[Previous Technical Literature] [Patent Document]

[Patent Document 1] International Publication No. 2013/077158

[Patent Document 2] Japanese Patent Laid-Open Publication No. 2012-3467

A computer program called a bot that automatically interacts with a server on a specific website on a network such as the Internet is known.

As a countermeasure against improper login by such a robot, a technique for determining whether a request from a terminal device is required for human-based operation has been proposed (for example, refer to Patent Documents 1 and 2 above).

In Patent Document 1, as an authentication device that authenticates an access request from a client terminal, an authentication device that generates authentication for authentication is received upon receiving an access request from a client terminal. By using a string, the image data of the authentication image and the input request of the authentication string included in the authentication image are transmitted to the client terminal, and are transmitted from the client terminal upon receiving the input request. The input string determines whether the input string matches the authentication string, and if the input string matches the authentication string, the access request from the client terminal is authenticated.

By using an authentication string as an image that can be recognized by illusion as an authentication image, it is difficult for a robot that does not cause erroneous interpretation to correctly answer the authentication string, thereby achieving authentication accuracy for access requirements. Upgrade.

Further, Patent Document 2 discloses that the terminal device displays an image for which the color is not processed and a processed image, and determines which image is a processed image to determine whether the request is based on a human operation or a robot. Certification method.

Here, whether or not the authentication process involved in the determination of the person as described above is important in preventing various troubles caused by the robot.

Accordingly, the present invention overcomes the above problems and aims at the operation for determining whether a request from a terminal device is a human operation. The authentication process seeks to improve the authentication accuracy.

The information processing device according to the present invention includes: a request accepting unit that accepts a request transmitted by the terminal device; and an image selecting unit that is defined based on user identification information that can be obtained based on the pre-recorded terminal device The image is a user-selected image, and one or a plurality of images are selected as the display target image; and the display control unit causes the pre-recording terminal device to display a question screen, wherein the image is selected by the pre-recording image selection unit. The object image is displayed in the front note, and one or more of the image of the display object is displayed in such a manner that the user's strange feeling is evoked; and the input information receiving unit receives the input information of the question mark screen. And the answer determination unit determines whether the answer to the pre-question question screen is a correct answer based on the pre-record input information received by the pre-recorded information receiving unit; and the request processing unit determines based on the pre-answer determination unit The result is the processing of the pre-request.

According to the above-mentioned questioning screen, it is easy for a person to make a correct answer by using a user-related image that is related to the user's user identification information, and it is easy to make a correct answer, as opposed to Therefore, it is difficult for the robot to determine whether it will arouse the strange feeling that human beings have and it is difficult to answer correctly.

Moreover, the questioning screen can be changed with each user (each user identification information), so that the cracking of the authentication process by the robot can be made more difficult.

According to the information processing device of the present invention, the front-view user-related image system is managed in association with the text, and the pre-recording display control unit displays the target image and the image corresponding to the pre-recorded object. It is preferable that the combination of the pre-recorded characters displayed is such that the pre-recording terminal device displays a pre-recording question screen that evokes a strange feeling.

If the strange feeling is evoked by the combination of the characters displayed corresponding to the display target image, the image processing required to evoke the strange feeling can be realized by synthesizing the characters of the image. Or, when the image is separated from the text, image processing is not required.

According to the information processing device of the present invention, the pre-recording image selecting unit manages the pre-recorded user-related image of the number of images as the pre-recorded display image for each of the pre-recorded user identification information and corresponds to The combination of the pre-recorded characters of the user-related image selects the pre-recorded display target image and the text displayed corresponding to the pre-recorded display target image from among the pre-recorded user-related images and the pre-recorded characters managed by the user; the pre-recording display control unit It is preferable that the pre-recording question screen is displayed by the pre-recording terminal device based on the pre-recorded display target image and the pre-recorded character selected by the pre-recording image selecting unit.

Thereby, by preparing a relatively small number of combinations of images and characters for use, it is possible to display a large number of variations of the questioning screen by these combinations.

The information processing device of the present invention, wherein the information is managed for each of the pre-recorded user identification information: by the user knowledge The action history information related to the browsing of the user's image defined by the information; the pre-recording image selection unit selects the pre-recorded user-related image of the browsing performed by the pre-recording user based on the pre-recorded action history information. It is preferable to know the estimated image and select one or a plurality of images to know the estimated image as the pre-recorded target image.

Thereby, the estimated estimated image that is estimated to be known by the user actually browsing can be displayed at the time of authentication.

According to the information processing device of the present invention, it is preferable that the pre-recording image selection unit excludes past information that has been equal to or longer than a predetermined time from the previous action history information, and selects the pre-recorded known estimated image.

In this way, images that are newer to the user will be displayed at the time of authentication.

According to the information processing device of the present invention, the pre-recorded display control unit is managed by the pre-recorded display image, and the pre-recorded display control unit is displayed by the pre-recorded display target image and the pre-recorded display target image. The combination of the preceding characters is displayed so that the pre-recording terminal device displays the pre-recording question screen that evokes the pre-recording feeling; the information of the pre-character text corresponding to each of the pre-recorded pre-determined images is obtained, and is displayed on the pre-recording question screen. It is ideal to manage the information on the different pages of the web page together with the pre-recorded notification image.

In this way, on the question screen, the image to be displayed is displayed with the knowledge of the estimated image and the text combined with the image to be displayed. The newsletter also displays information that is presumed to be known to the user.

According to the information processing device of the present invention, the information of the type of tendency preferred by the user defined by the user identification information is managed for each of the pre-recorded user identification information; the pre-recording image selection unit In the image in the memory portion in which the image is managed and memorized for each type, the image to which the type of the tendency preferred by the user is preferred is selected as the estimated estimated image. It is preferable to select one or a plurality of pre-recorded known estimation images to display the target image as a pre-record.

Thereby, as the known estimated image, an image other than the image actually estimated by the user is selected.

According to the information processing device of the present invention, the pre-recording control unit preferably selects one or a plurality of pre-recorded user-related images that are moving images as the pre-recording target image.

Thereby, a moving image is displayed as a display target image in the question screen.

Further, the information processing method according to the present invention is an information processing method executed by the information processing device: the request accepting step is a process of accepting a request sent by the terminal device; and the image selecting step is based on the pre-recording The image defined by the user identification information obtained by the terminal device is one of the user-related images, and one or more images are selected as the display target image; and the display control step causes the pre-recording terminal device to display the questioning screen. Among them, the image to be displayed is selected before the image selection step is selected, and the image of the display object is displayed first. Or a plurality of images are displayed in such a manner as to arouse the user's strange feeling; and the input information receiving step is to receive the input information of the previous questioning screen; and the answer determining step is based on the pre-recording information. The pre-recorded input information received by the step determines whether the answer to the pre-question question screen is the correct answer; and the request processing step performs the processing of the pre-log request based on the determination result made by the pre-answer step.

Even with such an information processing method, the same effect as the information processing apparatus described above can be obtained.

Further, the program of the present invention is a program for causing the information processing apparatus to execute processing to execute the above-described information processing method.

Moreover, the memory medium of the present invention is a memory program. The above information processing device is realized by these programs or memory media.

According to the present invention, it is possible to improve the authentication accuracy for the authentication processing required for determining whether or not the request from the terminal device is a human operation.

Moreover, the question screen can be changed with each user (each user identification information), so that the cracking of the authentication process by the robot can be made more difficult, and the authentication accuracy can be improved.

[1-1. Outline of Network System]

Fig. 1 shows an example of a network system 1 as a premise in the first embodiment. The network system 1 functions as an EC (EC: electronic commerce) system.

The network system 1 is configured, for example, through the Internet 2 as the Internet, and allows the shopping website management system 3, the plurality of user terminals 4, 4..., the plurality of shop terminals 5, 5... Communicate with each other.

The user terminal 4 is a computer device having a web browser. As the user terminal 4, for example, a high-performance mobile phone can be cited. A smart phone), a mobile phone, a portable information terminal (PDA), a portable or desktop personal computer (PC), etc., but the type of the user terminal 4 is not limited to these.

The user terminal 4 transmits an HTTP (Hypertext Transfer Protocol) request to the shopping server 3a or the like in the shopping site operation system 3 to request a web page or a predetermined process. Further, the user terminal 4 receives and displays the web page sent in response to the HTTP request on the web browser. Thereby, the user can browse or operate the desired webpage.

The shopping website operation system 3 includes a shopping server 3a composed of a computer device, a product DB (database) 3b, a user DB 3c, and an image DB 3d. Each of these devices can communicate with each other through a network such as a LAN (Local Area Network).

The shopping server 3a performs various processes based on an HTTP request sent from the user terminal 4. For example, the generation and delivery of various web pages (for example, product web pages, shopping basket web pages, ordering web pages, etc.), and purchase processing corresponding to the order determination operation by the user are performed.

In the network system 1, the virtual shopping mall website (EC website: shopping server) is provided to the user (user of the user terminal 4) by the shopping server 3a. There are a plurality of stores (the franchise stores of the virtual shopping malls) in the EC website. The staff of each store registers the products of their own stores through the computer device that is the store terminal 5, and various types of products of various types of stores are uploaded to the EC website. The user can access the EC website by the user terminal 4. And buy the goods you want.

Further, in this example, although the case where the business transaction in the network system 1 is the object of the commodity is exemplified, the object of the business transaction may also be the service.

In the shopping website operation system 3, the product DB3b stores information on the products registered through the shop terminal 5. Specifically, the identification element required to identify the product is the product ID, and the product information, the product image, the specification, the product summary information of the product, or the advertisement information, etc., are memorized. . In addition, the product DB3b also stores a data file of a product web page written in a markup language such as HTML (HyperText Markup Language) or XML (Extensible Markup Language).

With such a product DB3b, for example, a product search or the like can be performed based on an input keyword or the like.

Here, when the user uses the EC website, the user can log in to the shopping website management system 3. When the member logs in, the user registers the necessary information such as the user ID (user identification information), password, name, mail address, delivery destination information (address information), credit card number, and the like. The user logs in to the EC website by using the user ID and password that have already been registered, and the trouble of re-entering the necessary information can be saved when the product is purchased in the EC website.

The user DB3c memorizes the user information registered by the user who is a member as described above.

Even in user DB3c, the system also follows each user ID. The memory includes: information on the browsing of the product page, the input of the product to the shopping basket, the purchase of the product (ordering), and the information of the product that has been bookmarked as a favorite product (Zhongyi Information), etc. Information related to the resume (hereinafter referred to as "action history information").

Further, in the user DB 3c, the interest information of each user analyzed based on the action history information and the like described above is also stored for each user ID. The interest information is, for example, information on the type of tendency that the user prefers from the browsing history of the product, the purchase history, the bookmarked product, or the like, or the price band or manufacturer of the purchased product. . In the following interest information, the information on the type of tendency preferred by the user is referred to as "preference type information Ij".

Here, in the following, the above-mentioned information managed by the user DB 3c for each user ID is collectively referred to as "user management information Iu".

Here, the shopping server 3a performs authentication processing on a specific request made to the terminal device such as the user terminal 4. In an embodiment, the authentication process is performed to determine whether the request from the terminal device is based on a human operation or based on a computer program that is a robot.

Such authentication processing can be performed, for example, at the time of being requested to log in to accept a particular service provided by the EC website. Specifically, it is required to use the login box (for example, the input box of the user ID and the password) for logging in on the top-level webpage of the EC website, and to purchase the product on the EC website. At the time of login, when you are logged in to view the user information that has been logged in, When the user who has registered the user information is edited and requested to log in, etc.

At this time, authentication is required for each login, which is an excessive burden for a normal user and is not ideal. Thus, the terminal device requiring authentication can also be defined based on the predetermined criteria. For example, if the previous authentication has passed the predetermined time or longer, or the terminal device that has failed to log in for the specified number of times within the specified time by the same IP address, it may be estimated as an improper terminal, and the terminal is requested. Certification.

Further, the authentication process can be performed for the terminal device that is logged in. For example, when the user of the terminal device requests to download a specific file provided by the EC website during login, the user of the terminal device considers authentication as the permission condition for the download.

Here, in order to use the robot to try to make improper use of the service in the login service such as the download service, the robot must log in by an account (user ID and password), but as a case where the robot may log in. For example, using an account that is improperly obtained from others, that is, a so-called "counterfeiting".

The details of the authentication process performed by the shopping server 3a will be described later.

Here, in FIG. 1, there are various examples of the configuration of the network 2. For example, the Internet is the first to be considered as: intranet, inter-enterprise network, LAN (Local Area Network), CATV (Community Antenna TeleVision) communication network, virtual private network (Virtual Private Network), telephone line network, Mobile communication Network, satellite communication network, etc.

Further, various examples of the transmission medium constituting all or part of the network 2 are also conceivable. For example, IEEE (Institute of Electrical and Electronics Engineers) 1394, USB (Universal Serial Bus), power line carrier, telephone line, etc., infrared, Bluetooth (registered trademark), 802.11 wireless such as IrDA (Infrared Data Association) Wireless such as mobile telephone networks, satellite lines, and surface wave digital networks are available.

[1-2. Hardware configuration of computer device]

FIG. 2 shows a hardware configuration of a computer device constituting each device (product DB3b, user DB3c, user terminal 4 (terminal device), shop terminal 5) including the shopping server 3a shown in FIG. .

In FIG. 2, the CPU (Central Processing Unit) 101 of the computer device is loaded in accordance with a program stored in the ROM (Read Only Memory) 102 or a program loaded from the storage unit 108 to the RAM (Random Access Memory) 103. Perform various processing. The RAM 103 is also suitable for storing information necessary for the CPU 101 to execute various processes.

The CPU 101, the ROM 102, and the RAM 103 are connected to each other through the bus bar 104. An input/output interface 105 is also connected to the bus bar 104.

An input device 106, an LCD (Liquid Crystal Display), and a keyboard, a mouse, a touch panel, and the like are connected to the input/output interface 105. A memory (display device) such as a CRT (Cathode Ray Tube) or an organic EL (Electroluminescence) panel, and a memory device such as an output device 107, an HDD (Hard Disk Drive), or a flash memory device. The unit 108 and the communication unit 109 required to communicate with each other with the external device.

The input/output interface 105 can also be connected to the media drive 110 as needed, and can be suitably loaded with a removable medium 111 such as a magnetic disk, a optical disk, an optical disk, or a semiconductor memory. The removable medium 111 is removable. Write or read information.

In such a computer device, data or programs are uploaded or downloaded by communication caused by the communication unit 109, or data or programs can be received through the removable medium 111.

The CPU 101 performs processing operations based on various programs, and particularly in the computer device as the shopping server 3a, the information processing or communication described below is executed.

[1-3. Authentication method of the first embodiment]

Referring to the functional block diagram of Fig. 3, the authentication process performed by the shopping server 3a in response to a request from the terminal device of the user terminal 4 or the like will be described.

In addition, in the following description, unless otherwise indicated, it is assumed that the service requested by the terminal device is a service that can be enjoyed during login. In other words, the robot is a request for performing a service request by improperly logging in with another person's account as described above.

In FIG. 3, the various processes executed by the shopping server 3a to realize the authentication process of the first embodiment are divided into blocks for each function.

As shown in the figure, the shopping server 3a can be divided into a function receiving request unit F1, a video selection processing unit F2, a display control processing unit F3, an input information reception processing unit F4, and an answer determination processing unit F5. And request processing unit F6.

The request acceptance processing unit F1 performs reception of a specific request transmitted by the terminal device. That is, in this example, it is a request for a service that can be enjoyed in the above login.

The image selection processing unit F2 selects a plurality of images as the display target image Gd from among the images defined by the user ID acquired from the terminal device that transmitted the request, that is, the user-related image.

The display target image Gd is an image to be placed on the question screen used for the authentication process, and as will be described later, the fixed number is displayed on the question screen to evoke a strange feeling of the user.

In this example, as the "user-related image" described above, the image that is estimated to be known to the user is known, that is, the estimated image Gi is known.

The estimated image Gi is selected from the product images stored in the product DB 3b. In other words, the display target image Gd arranged on the question screen is an image selected from among product images that the user may know.

The image selection processing unit F2 selects and knows the estimated image Gi based on the user management information Iu stored in the user DB 3c. Specifically, the estimated estimated image Gi is selected based on the action history information stored in the user DB 3c for each user ID. For example, based on the purchase history information of the product, the product image of the product having the history of purchase is selected as the known estimated image Gi. Alternatively, based on the bookmark information of the product, the product image of the bookmark product is selected as the known estimated image Gi. The known estimated image Gi in the first embodiment is an image that is estimated to be known by the user.

At this time, the number of images selected as the known estimated image Gi is at least the number of images selected as the display target image Gd (in this example, "3"). In this example, one piece of the product for knowing the estimated image Gi is selected. Therefore, as the process of selecting the estimated image Gi, each of the plurality of products that meet the condition that "the user is already known" is selected. The processing of the product image.

Further, in the EC website provided by the shopping server 3a, the product image is displayed on the product web page, and the product bookmark is performed by operating the "zhongyi" button arranged on the product web page, so in this example, The action history information is equivalent to "action history information related to images".

In the first embodiment, a method for causing the user to evoke a strange feeling to the display target image Gd is to display a different product name corresponding to the product image as the display target image Gd. This method of information.

Therefore, the image selection processing unit F2 performs the selection process of knowing the selection of the estimated image Gi or the selection of the display target image Gd as described above, and also performing selection processing for displaying the desired product name information in association with the display target image.

In the question screen, the display target image Gd that does not arouse the strange feeling and the display target image Gd that evokes the strange feeling are displayed on the question screen, and the display object that does not arouse the strange feeling is displayed as the product name information. The image Gd is a product name information for selecting a product to be matched, and a product name information for a product that is different from the matching product is selected for the display target image Gd that evokes a strange feeling.

Further, in the EC website, the product name information can be expressed as information displayed on the same product web page together with the corresponding product image.

Here, the knowledge of the estimated image Gi or the product name necessary for the display of the question screen can be selected one by one in response to the request from the terminal device.

However, in this example, in order to avoid the selection process of knowing the estimated image Gi or the product name information every time the authentication process is performed in response to the request, the image selection processing unit F2 performs the action for each user ID in advance. The selection of the estimated estimated image Gi and the product name information of the candidate display image Gd displayed on the question screen.

Specifically, the image selection processing unit F2 selects and satisfies all the user IDs managed by the user DB 3c for each user ID based on the action history information and satisfies the "presumed to be known by the user". After a plurality of products of the condition, the product image of the product is selected as the estimated estimated image Gi, and the product name information of the product is also acquired, and the image ID of the selected estimated image Gi and the acquired image are obtained. The product name information is stored in correspondence with each user ID.

In this case, in order to prevent the image of the user's memory from being blurred based on the old action history, the image selection processing unit F2 selects the past information that has been equal to or longer than the predetermined time in the action history information. Excluding and then knowing the selection of the estimated image Gi and the product name information.

FIG. 4 is a diagram showing an example of the challenge picture material management information I1 constructed by the prior selection process performed for each user ID.

As shown in the figure, in the challenge picture material management information I1, each user ID is associated with: an image ID selected as a product image for knowing the estimated image Gi, and corresponding to the selected product image (also That is, the product name information (text information) for the same product.

Further, the challenge picture material management information I1 is stored in the shopping website operation system 3 in a state in which the shopping server 3a can read it. In this example, the question screen material management information I1 is stored in a memory device provided in the shopping server 3a such as the memory unit 108 shown in FIG.

The image selection processing unit F2 in this example selects the display target image Gd and the display target image Gd based on the question screen material management information I1 as described above when receiving the request from the terminal device. And the information of the displayed text.

In other words, the image selection processing unit F2 is an image ID and a product name information corresponding to the user ID corresponding to the user ID acquired from the terminal device among the user IDs in the challenge screen material management information I1. Among them, the image ID and the product name information which should be displayed on the number of question screens ("3" in this example) are selected. In this case, regarding the product name information, it is not simply selecting information corresponding to each of the selected image IDs, and in order to realize the above-described strange feeling calling method, at least one of the selected image IDs is selected. The image ID establishes the corresponding product name information (deliberately selects a text that is inconsistent with the product image). For example, if "I0001", "I0002" and "I00XX" in the figure are selected as the image ID, the product name information is selected, for example, the product name information associated with "I0001" and "I0002", and "I00XX" The image ID other than the image ID is created.

Specifically, the image selection processing unit F2 selects the image of the image (hereinafter referred to as the "aliased object image Gc") that is to be used for the sense of the strangeness, and is consistent with the texture information management information I1. The image ID of the fixed number (in this example, "1") is selected among the image IDs corresponding to the user ID, and among the image IDs corresponding to the user ID, the selection and the image ID are different from The other image ID of the selected image ID establishes the corresponding product name information.

Further, the image selection processing unit F2 selects a display target image Gd other than the different sense target image Gc from the user ID corresponding to the user image management information I1. The image ID of the fixed number (in this example, "2") is selected among the IDs, and the product name information corresponding to the selected image ID is selected.

At this time, the selection of the image ID may be performed according to the predetermined rule, but in consideration of the doubt that the algorithm of the robot for cracking the authentication process is constructed by the selection rule of the display target image Gd, the design is random. Choice is ideal.

Referring back to FIG. 3, the display control processing unit F3 performs a process of causing the terminal device that has transmitted the request to display the question screen required for authentication. Specifically, in the question screen of the present example, the display target image Gd selected by the image selection processing unit F2 is disposed, and the display target image Gd of the predetermined number of the display target images Gd is combined by the combination. The product name information is displayed to evoke the sense of the user's sense of dissimilarity.

Fig. 5 is a diagram showing a first example of a question screen.

As shown in the figure, in the question screen of the first example, the display target image Gd selected by the image selection processing unit F2 is combined with the image system in which the product name information selected by the image selection processing unit F2 is also configured. At the same time, it is also configured to: text information (a, b, c) assigned to each image as an identification element of the image, text information as a question text, and text information of an option to answer the question, used to select any A check box cb1~cb3 required for an option.

In the case of the display target image Gd, the product image corresponding to the product "crab" is selected as the strange image target image Gc. Specifically, the product corresponding to the product "crab" The image obtained by synthesizing the product name information corresponding to the product "sea urchin" is displayed as an image required to evoke the strange feeling. In addition, in FIG. 5, the product image information corresponding to the product "camera" corresponding to the product image corresponding to the product "camera" is synthesized, and the same product is synthesized for the product image corresponding to the product "toilet paper". The image of the product name information corresponding to the toilet paper is displayed as an image that does not evoke a strange feeling.

Fig. 6 is a diagram showing a second example of the question screen.

In the question screen of the second example, the display target image Gd selected by the image selection processing unit F2 and the product name information selected by the image selection processing unit F2 are individually (separated), and are also arranged: The text information (a, b, c) assigned to each image as the identification element of the image, the text information as the text of the question message, the text information of the choice of the answer to the question, and the check required to select any option Box cb1~cb3.

In the example of FIG. 6, the display target image Gd selected as the abnormal image target image Gc is a product image corresponding to the product "crab". In other words, in the example of FIG. 6, the position corresponding to the product image (display target image Gd) corresponding to the product "crab" (in this example, the vicinity of the lower side of the image) is arranged corresponding to the product "sea urchin". The product name information is displayed, and the display object image Gd is displayed in such a manner as to evoke a strange feeling of the user. On the other hand, for the product image corresponding to the product "camera" and the product image corresponding to the product "toilet paper", the product name information corresponding to the product "camera" and the product "toilet paper" are placed at their respective positions. The corresponding product name information, about these The display target image Gd is displayed in such a manner that it does not evoke a strange feeling of the user.

The display control processing unit F3 generates a question screen caused by the aspects exemplified in the first example or the second example based on the display target image Gd and the product name information selected by the image selection processing unit F2, and causes the image to be sent out. The requested terminal device is displayed.

In FIG. 3, the input information reception processing unit F4 receives input information to the question screen. Specifically, in the question screen of FIG. 5, the check operation information of any one of the check boxes cb1 to cb3 is received from the terminal device as input information to the question screen, and is the question screen of FIG. Then, the information input in the input box ib is received from the terminal device as input information to the question screen. These input information can be said to be the answer information to the question screen.

The answer determination processing unit F5 determines whether or not the answer to the question screen is the correct answer based on the input information received by the input information reception processing unit F4.

In the case of the question screen shown in the previous FIGS. 5 and 6, the answer to select the image that will evoke the strange feeling is set as the correct answer, so whether or not the correct answer is determined is the image displayed on the question screen. Among them, it is judged whether or not the answer is selected, and the trade name information selected so as not to satisfy the correspondence relationship between the image ID and the product name information (text information) in the question picture material management information I1 shown in FIG. 4 is Corresponding to the displayed image.

The request processing unit F6 is based on the answer determination processing unit F5. The result of the determination is made to perform processing on the request of the terminal device. Specifically, when the result of the determination that the answer to the question screen is the correct answer is obtained, the web page (hereinafter referred to as "service web page") required to provide the service for the response request is displayed on the terminal device, and the pair is obtained. When the answer to the question screen is not the result of the determination of the correct answer, the process of causing the terminal device to display the service page is not executed, and the error answering process is performed.

In the error response processing of this example, it is not immediately recognized as an authentication error with a false answer, but the number of times the terminal device makes a false answer within a predetermined time (hereinafter referred to as "the number of false answers m"), When the number of misrecognition allowable times M (M is a natural number of 2 or more) is exceeded, at least the reception of the input information to the question screen from the terminal device and the determination of the answer to the question screen are repeated. In other words, when the result of the determination of the incorrect answer is obtained by the answer determination processing unit F6, the request processing unit F6 executes at least the input information reception processing unit F4 if the number of misrecognitions m is equal to or greater than the allowable number of misrecognitions M. The answer of the input information received and the answer determination by the answer determination processing unit F5 determines that the authentication error process is performed if the number of misrequests m is equal to or greater than the number of misrecognition allowable times M. Specifically, as the authentication error processing, a process of causing the "error page" indicating the authentication error to be displayed by the terminal device is performed.

Here, when the error is allowed within the allowable number of misrecognitions M as described above, in this example, each time the mis-answer is made, the terminal device displays a different question screen to prevent the authentication accuracy from being lowered. . In this case, as the "different kinds of question screens", the combination of the image and the product name information remains unchanged, and only the question text is changed, and vice versa. or It is also possible to make the question text, and the combination of the image and the product name information different.

In this example, at least the combination side of the image and the product name information is different. When the number of misrecognitions m is within the number of times of the misrecognition, the display object image Gd and the product name are obtained from the image selection processing unit F2. The selection of information will be processed again.

[1-4. Processing procedure]

A procedure for executing the processing to be performed in the above-described authentication method of the first embodiment will be described with reference to the flowcharts of Figs. 7 to 9 .

Fig. 7 is a diagram showing a procedure for performing processing for knowing the above-described prior selection of the estimated image Gi and the article name information. Further, the processing shown in FIG. 7 is executed by the CPU 101 in the shopping server 3a based on a program stored in a predetermined memory device such as the ROM 102 or the storage unit 108.

In FIG. 7, the shopping server 3a sets the start value nS as the processing target ID identification value n in step S101. The processing target ID identification value n is a value required to identify the user ID of the execution target of the process related to the pre-selection of the estimated image Gi and the product name information.

In this example, the pre-selection processing of the estimated image Gi and the product name information can be performed by dividing the range of the user ID of the object. The start value nS and the end value nE to be described later are, for example, an operator of the shopping server 3a, etc., in order to determine the range of the user ID of the target. The value set.

When the start value nS is set as the processing target ID identification value n in step S101, the shopping server 3a is estimated to be the user-known by the action history information for the nth user ID in step S102. Product images and trade name information are selected. In other words, based on the action history information, the nth user ID stored in the user DB 3c satisfies the condition that the product having the purchase history or the bookmarked product satisfies the condition that the user is already known. After the plurality of products are selected, the product images of the selected products are selected as the known estimated image Gi, and the product name information of the product is selected.

At this time, the shopping server 3a excludes the past information that has been equal to or longer than the predetermined time in the action history information, and then selects the known estimated image Gi and the product name information.

In the subsequent step S103, the shopping server 3a stores the video ID and the product name information of the product image that is selected as the estimated image Gi, and the user ID (nth user ID).

Then, in the next step S104, the shopping server 3a determines whether or not the processing target ID identification value n is equal to or greater than the end value nE. When the processing target ID identification value n is not equal to or greater than the end value nE, the shopping server 3a proceeds to step S105 to increment the processing target ID identification value n (n←n+1), and returns to step S102.

That is, the processing object ID identification value n = start value nS - end value nE Within the range, the selection of the estimated image Gi and the product name information corresponding thereto and the corresponding memory with the user ID are known for each user ID. Thereby, the question picture material management information I1 as shown in the previous FIG. 4 is constructed.

When the processing target ID identification value n is equal to or greater than the end value nE, the shopping server 3a ends the prior selection processing shown in the figure.

FIG. 8 illustrates a process performed corresponding to the time of authentication.

In addition, in FIG. 8, the processing shown as "shopping server" is executed by the CPU 101 in the shopping server 3a based on a program stored in a predetermined memory device such as the ROM 102 or the storage unit 108.

In FIG. 8, the terminal device of the user terminal 4 or the like, as the access request processing of step 201, is a request for the shopping server 3a to access the service web page required to accept the specific service provided by the EC website. .

The shopping server 3a, upon receiving an access request from the terminal device, executes a question screen generation process in step S301.

FIG. 9 illustrates a process executed as the question screen creation processing of step S301.

In FIG. 9, the shopping server 3a acquires the user ID corresponding to the terminal device in step S401. As described above, since the premise is that the service requested by the terminal device is a service that can be enjoyed during login, the shopping server 3a obtains the login information corresponding to the terminal device by transmitting the login information of the requested terminal device. User ID.

In the subsequent step S402, the shopping server 3a selects the display target image Gd used in the question screen based on the user ID and the question screen material management information I1. In other words, in the challenge picture material management information I1, an image to be displayed on the number of question screens (for example, "3") is selected from among the image IDs associated with the user ID acquired in step S401. ID. At this time, the selection of the image ID is to prevent the image displayed on the challenge screen from being fixed as much as possible, and is randomly selected among the image IDs associated with the user ID acquired in step S401.

In the next step S403, the shopping server 3a selects the image of the number of the display target images Gd as the different sense target image Gc. Specifically, in this example, one of the display target images Gd is selected as the image ID of the abnormal image of the target image Gc.

Thereafter, in the subsequent step S404, the shopping server 3a selects and acquires the product name information of the strange object image Gc. In other words, among the image IDs associated with the user ID acquired in step S401, the image IDs different from the image IDs that have been selected as the different sense image Gc are selected in the challenge picture material management information I1. Create corresponding product name information to select and obtain.

Then, in the next step S405, the shopping server 3a selects and acquires the product name information of the remaining display target image Gd. In other words, among the image IDs of the display target image Gd selected in step S402, the image IDs for which the image ID of the different sense target image Gc is excluded are recorded in the question screen material management information I1. These image IDs are created and corresponding information is selected and obtained.

In the subsequent step S406, the shopping server 3a generates HTML data of the question screen using the selected display target image Gd and the acquired product name information. For example, when the question screen of the first example illustrated in FIG. 5 is displayed, the shopping server 3a generates step S404 for the display target image Gd selected as the strange image target image Gc in step S403. The image obtained by the product name information obtained in the middle, and the image obtained by synthesizing the product name information acquired in step S405 on the remaining display target image Gd, as the image displayed on the question screen, and these are The image, the text information as the identification element of the image, the text information as the question text, the text information of the answer option, and the check box cb are the HTML data of the web page set as the predetermined composition, and are generated as the HTML data of the question screen.

Further, when the question screen as the second example (FIG. 6) is displayed, the shopping server 3a sets the display target image Gd selected in step S402 and the product name information acquired in steps S404 and S405, respectively. The text information of the image recognition element, the text information as the question text, the text information of the answer option, and the check box cb are the HTML data of the web page set to the predetermined composition, and are generated as the HTML data of the question screen. At this time, the product name information acquired in step S404 is framed at a position corresponding to the display target image Gd selected as the abnormal image target image Gc, and the product name information acquired in step S405 is patterned. It is placed at the position corresponding to the remaining display object image Gd.

In addition, for the sake of confirmation, the display target image Gd is displayed first. The image ID acquired in step S402 is acquired from the product DB 3b.

In accordance with the execution of the processing of step S406, the shopping server 3a ends the question screen generation processing of step S301.

Hereinafter, the HTML data of the question screen generated in step S406 is referred to as "question screen HTML data".

Referring back to Fig. 8, in step S302, the shopping server 3a transmits the question screen HTML data generated in the question screen creation processing described above to the terminal device that has made the request in the previous step S201.

In the terminal device, it is waited for the reception of the HTML data of the question screen in step S201, and if the HTML data of the question screen is received, the question screen display process is executed in step S203.

Then, the terminal device performs input acceptance of the answer to the displayed question screen in the subsequent step S204, and inputs the input answer information (input information to the question screen) to the shopping server 3a in step S205. send.

The shopping server 3a waits for the answer information from the terminal device in step S303, and if the answer information is received, analyzes the answer information in step S304, and determines whether the answer is consistent with the correct answer in the subsequent step S305. .

In step S305, if a negative result in which the answer does not match the correct answer is obtained, the shopping server 3a proceeds to step S306 to increment the value of the number of false answers m (m←m+1), and determines the error in step S307. Whether the number of answer m is the number of misrecognitions allowed M or more.

Here, the initial value of the value of the number of misrequests m is "0". The value of the number of misrequests m is reset to 0 for each terminal device that has made the request, after a predetermined time has elapsed from the point at which the initial value increase of the initial value is performed. Although the illustration is omitted, the shopping server 3a performs the reset processing of the number of misrequests m of each of the terminal devices in parallel with the processing of FIG.

In step S307, if the number of misrecognitions m is not equal to or greater than the number of misrecognition allowable times M, the shopping server 3a transmits a false alarm to the terminal device in step S308, and returns to the previous step S301.

In other words, the error answer within the allowable number of misrecognitions M is a process of causing the terminal device to display a new question screen.

On the other hand, if the number of false positives m is equal to or greater than the allowable number of false positives M in step S307, the shopping server 3a transmits an authentication error notification to the terminal device in step S309, in the subsequent step S310. The error web page HTML data is transmitted to the terminal device, and the processing shown in FIG. 8 is ended.

Further, in the previous step S305, if the answer is an affirmative result in accordance with the correct answer, the shopping server 3a transmits the correct answer notification to the terminal device in step S311, and the service web page HTML is transmitted in the subsequent step S312. The data is transmitted to the terminal device, and the processing shown in FIG. 8 is ended.

The terminal device waits for the above-mentioned false answer notification (S308), authentication error notification (S309), or correct answer notification in step S206. The reception of any of (S311) determines the notification type in step S207 when there is a reception.

If the notification type is a false answer, the terminal device returns to step S202 to wait for the reception of the new challenge screen.

If the notification type is an authentication error, the terminal device proceeds to step S208 and performs display processing of the error web page based on the error web page HTML data received from the shopping server 3a, and ends the processing shown in FIG.

When the notification type is the correct answer, the terminal device proceeds to step S209 and performs display processing of the service web page based on the service web page HTML data received from the shopping server 3a, and ends the processing shown in FIG.

In addition, in the above, although an example is given in which the question screen required for authentication is displayed in response to a request for a service that can be enjoyed during login, as a question screen, it is also considered to be used in the login screen. In the case where the input box of the ID and the password is displayed together, in this case, the terminal device that has made the request is in the non-login state, and the user ID corresponding to the terminal device may not be acquired. In the case of a legitimate user other than the robot, the information of the past login may also be a cookie of the browser remaining in the terminal device. In this case, the user ID can be obtained, but the robot is caused by the robot. Improper terminals have a high probability of not logging in in the past, and they are not able to obtain the corresponding user ID. When the user ID corresponding to the terminal device cannot be acquired in response to the request from the terminal device, the user ID cannot be obtained from the terminal device. When the image material management information I1 is acquired, the image or the product name information is acquired. Therefore, the display target image Gd and the product name information for the question screen are selected from the separately prepared plurality of images and product name information, and the predetermined number is given. The person feels the same feeling and shows it. At this time, in order to prevent the combination of the image or the product name information displayed on the question screen from being fixed, the selection system is performed at random.

The same manner as in the case where the user ID cannot be obtained is the same in the second embodiment to be described later.

In the above description, the number of display of the display target image Gd on the question screen is set to be plural. However, the display number system may be at least "1". In other words, it is also possible to know that one of the estimated images Gi is selected as the display target image Gd, and the selected display target image Gd is displayed on the question screen in a manner that evokes a strange feeling. As the question screen in this case, it is only necessary to arrange text information such as "Do you think this image has a strange feeling?" as the question text, and it is possible to ask for the presence or absence of a different sense of the displayed display image Gd. .

[1-5. Summary of the first embodiment]

As described above, the information processing device (the shopping server 3a) of the first embodiment includes the request accepting unit (the request accepting processing unit F1), and accepts the request transmitted by the terminal device; and the image selecting unit (image selection) The processing unit F2) selects an image that can be defined based on the user identification information acquired from the terminal device, that is, the user-related image. One or a plurality of images are selected as the display target image; and the display control unit (display control processing unit F3) causes the terminal device to display a question screen in which the display target image selected by the image selection unit is disposed, and One or more of the display target images are displayed in such a manner as to arouse the user's strange feeling; and the input information receiving unit (input information receiving processing unit F4) inputs the information to the questioning screen. And the answer determination unit (answer determination processing unit F5) determines whether the answer to the question screen is a correct answer based on the input information received by the input information receiving unit; and the request processing unit (request processing unit F6) The processing of the request is performed based on the determination result made by the answer determination unit.

According to the above-mentioned questioning screen, it is easy for a person to make a correct answer by using a user-related image that is related to the user's user identification information, and it is easy to make a correct answer, as opposed to Therefore, it is difficult for the robot to determine whether it will arouse the strange feeling that human beings have and it is difficult to answer correctly.

Therefore, the authentication accuracy required for the operation for determining whether or not the request from the terminal device is a person can be improved.

Further, the question screen can be changed with each user (each user ID), so that the cracking of the authentication process by the robot can be made more difficult, and the authentication accuracy can be improved. In particular, the administrator of the robot improperly obtains the information of the other person's account (user ID and password), and each of the requests is subjected to each authentication process when the respective account requests the robot to perform an inappropriate login. The displayed question screen changes with each user ID, so the authentication process The cracking will become difficult.

Further, in the information processing device according to the first embodiment, the user-related image system is managed in association with each other, and the display control unit displays the target image and the text displayed corresponding to the display target image. The combination is such that the terminal device displays a question screen that evokes a strange feeling.

If the strange feeling is evoked by the combination of the text displayed corresponding to the display object image, the image processing required to evoke the strangeness is synthesized by the text of the image (for example, as shown in FIG. 5). One example) is achievable and simple. Alternatively, when the image is separated from the text (for example, the second example shown in Fig. 6), image processing is not required.

Therefore, it is possible to reduce the display control processing of the challenge screen, that is, the processing load required for authentication.

Further, in the information processing device according to the first embodiment, the video selection unit manages each user identification information in that the number of the user-related images that are the number of images to be displayed as the display target image is more than the corresponding use. The combination of the characters of the related images, and the display target image and the text displayed corresponding to the display target image are selected from among the user-related images and characters managed by the user; the display control unit selects based on the image selection unit The display target image and text are displayed so that the challenge screen is displayed by the terminal device.

Thereby, by preparing a relatively small number of combinations of images and characters for use, it is possible to display a large number of variations of the questioning screen by these combinations.

Further, in the information processing device of the first embodiment, for each user identification information, the action history information related to the browsing of the image of the user defined by the user identification information is managed; the image selection is performed. The user selects the user-related image that the user has browsed based on the action history information to select the estimated image, and selects one or a plurality of known estimated images as the display target image.

Thereby, the estimated estimated image that is estimated to be known by the user actually browsing can be displayed at the time of authentication.

Therefore, the probability of correct answering by human beings can be improved, and the accuracy of authentication can be improved.

Further, in the information processing device according to the first embodiment, the video selection unit excludes the past information that has been equal to or longer than the predetermined time in the action history information, and selects the estimated estimated image.

In this way, images that are newer to the user will be displayed at the time of authentication.

Therefore, the probability of correct answering by human beings can be further improved, and the authentication accuracy can be further improved.

In the information processing device according to the first embodiment, the known estimated image system is managed in association with each other; the display control unit is a combination of the display target image and the text displayed corresponding to the display target image. In order to cause the terminal device to display a questioning screen that evokes a strange feeling; the information of the text corresponding to each of the known estimated images is taken as a text on the web page different from the web page displayed on the question screen. The images are managed together with information that prompts the user. Specifically, the information of the character in this example is regarded as being managed on the product web page together with the information that is known to the user by knowing the estimated image (product image).

As a result, on the question screen, the information to be displayed is displayed as the display target image, and the information of the character combined with the display target image is also displayed as information that is estimated to be actually viewed by the user.

Therefore, it is easier for the user to make a correct answer, which can improve the authentication accuracy.

<2. Second embodiment>

[2-1. System Overview and Certification Techniques]

In the second embodiment, instead of evoking the strange feeling of the user by the combination of the image and the character, the image is processed by the original image to evoke a strange feeling. In particular, in the following description, an image belonging to a type matching the type of tendency preferred by the user is selected as the known estimated image Gi, and at least one of the display target images Gd selected from the known estimated image Gi is selected. The object image Gd is displayed, and an example of processing required to evoke a strange feeling is performed.

In the following description, the same portions as those already described herein are denoted by the same reference numerals, and their description will be omitted.

Fig. 10 is a diagram showing an example of a network system 1' which is a premise in the second embodiment.

The difference from the network system 1 shown in Fig. 1 is to replace the shopping website operation system 3 and to set the shopping website operation system 3'. The shopping website operation system 3' replaces the shopping server 3a with the shopping server 3a' and the video DB3d, which is different from the shopping website operation system 3.

In the video DB3d, a plurality of images are managed and memorized according to each type. As a type, it can be inferred from the tendency of browsing or purchasing of a product, for example, regarding the type of fun. As an example, it is a type of baseball, soccer, golf, surfing, diving, mountain climbing, photography, railway, car, reading, music appreciation, and the like.

The image to be stored in the video DB3d is either a still picture or an animation, or both.

Fig. 11 is a diagram showing an example of image management information Im required for managing images stored in the image DB 3d.

The image management information Im is associated with each of the types exemplified in the above description, and the image IDs of the plurality of images selected in advance as the persons belonging to the type are associated with each other.

Such image management information Im is stored in the shopping website operation system 3' in a state where the shopping server 3a' can be read. In this example, the image management information Im is stored in, for example, the image DB 3d.

Fig. 12 is a functional block diagram in which the shopping server 3a' performs various processes for realizing the authentication process of the second embodiment, and is divided into blocks for each function.

The difference from the shopping server 3a in the first embodiment is that Instead of the display control processing unit F3, the display control processing unit F3' is replaced by the image selection processing unit F2' instead of the image selection processing unit F2.

The video selection processing unit F2' acquires the preference type information Ij of the user defined by the user ID based on the user ID acquired from the terminal device that has transmitted the request, based on the acquired preference type information Ij and The image management information Im shown in FIG. 11 selects the plural image belonging to the type of the tendency preferred by the user as the known estimated image Gi. Thereafter, a plurality of the selected estimated images Gi are selected and selected as the display target image Gd.

Also in the second embodiment, it is known that the selection of the estimated image Gi is performed in advance by the method of selecting the process in advance.

Specifically, the video selection processing unit F2' acquires the preference type information Ij corresponding to the user ID and the video management information Im for each user ID managed by the user DB 3c. Among the image IDs, the selection of the plurality of image IDs corresponding to the information of the type matching the acquired preference type information Ij and the processing of associating the selected image ID with the user ID are It is pre-executed by selecting the processing method beforehand.

FIG. 13 is a diagram showing an example of the question screen material management information I2 constructed by the above-described prior selection processing.

As shown in the figure, in the challenge picture material management information I2, for each user ID, the image ID of the complex image that is known as the estimated image Gi is selected based on the preference type information Ij.

The question screen material management information I2 is stored in the shopping website operation system 3' in a state where the shopping server 3a' can be read. In this example, it is stored in a memory device provided in the shopping server 3a' such as the storage unit 108 shown in Fig. 2 .

The video selection processing unit F2' selects the display target image Gd based on the challenge picture material management information I2 as described above in response to the request from the terminal device. In other words, the video selection processing unit F2' is among the video IDs corresponding to the user IDs corresponding to the user IDs acquired from the terminal device among the user IDs in the challenge screen material management information I2. The image ID to be displayed on the number of question screens ("2" in this example) is selected as the image ID of the display target image Gd.

Further, the selection process of knowing the estimated image Gi may be performed after receiving a request from the terminal device.

The display control processing unit F3' performs image processing on a predetermined number of display target images Gd among the display target images Gd selected by the image selection processing unit F2' so as to evoke a strange feeling of the user on the question screen. The appearance is shown.

Fig. 14 is a diagram showing an example of a question screen displayed by the control of the display control processing unit F3'.

In FIG. 14, it is shown that, as the question screen, the two display target images Gd selected by the image selection processing unit F2' respectively display images that have not been subjected to image processing and image processing (ie, intention) An example of a total of four images of an image that evokes a strange image. Specifically, in In the example of the figure, the image information of the text information of "a" and "b" in the figure is set as a non-processed image, and the image information of the text information of "c" is marked as "b". The image in which the text information is displayed is subjected to image processing by color reversal processing, and the image information marked by "d" is the image processing for up-and-down processing of the image indicated by the text information of "a". Processed image.

In the question screen at this time, the above-mentioned non-processed, processed images, and the text information (a~d) marked as the identification elements of each image, together with the text information and answer options as the question texts The check boxes cb1~cb4 required to select the answer are displayed.

In addition, as the image processing required to evoke the strange feeling, in addition to the color reversed or upside down, it is also possible to make various considerations. For example, it is conceivable that only the highlighted portion or the shaded portion of the original image is shaded upside down (the color is reversed), or the shape of the subject is curved or the like, or combined with other images, and the like.

Further, in particular, when the display target image Gd is a moving image, the image processing system can be implemented such that the reproduction speed is different from the original image (for example, slow reproduction or double speed reproduction), or the reproduction order is reversed from the original image ( This is called "reverse regeneration" processing.

The display control processing unit F3' generates a question screen based on the display target image Gd selected by the image selection processing unit F2' in the manner illustrated in Fig. 14 and displays it on the terminal device that transmitted the request.

Further, in the above description, all the images selected as the display target image Gd are all required to evoke the image required for the strange feeling. In the example of being displayed on the question screen as in the case of processing, the image processing required to evoke the strange image may be performed on at least one of the images selected as the display target image Gd.

[2-2. Processing procedure]

The procedure to be executed in order to realize the authentication method of the second embodiment described above will be described with reference to the flowcharts of Figs. 15 and 16 .

The processing shown in Figs. 15 and 16 is executed by the CPU 101 in the shopping server 3a' based on a program stored in a predetermined memory device such as the ROM 102 or the storage unit 108.

In addition, in FIGS. 15 and 16, the same processing as the processing already described is denoted by the same step number, and the description is omitted, unless otherwise specified.

Fig. 15 is a diagram showing a procedure for performing processing to know the pre-selection of the estimated image Gi.

In FIG. 15, the shopping server 3a' sets the start value nS as the processing target ID identification value n in step S101, and acquires the preference type information about the nth user ID in the subsequent step S501. Ij.

Then, in the next step S502, the shopping server 3a' obtains the image ID of the image to which the type belongs to the type of the tendency preferred by the user by the image DB 3d. That is, in the image management information Im memorized in the product DB3d, among the image IDs to which the information of the type corresponding to the acquired preference type information Ij is associated, the selected complex is selected. A plurality of image IDs are used as image IDs for knowing the estimated image Gi.

In the subsequent step S503, the shopping server 3a' stores the acquired image ID in association with the user ID.

When the memory processing of the step S503 is executed, the shopping server 3a' advances the processing to the previously described step S104, and if the processing target ID identification value n is not the end value nE or more, the processing object ID is recognized in the step S105. When the processing target ID identification value n is equal to or greater than the end value nE, the processing shown in FIG. 15 is ended.

By the processing of the above, the processing target ID identification value n = the start value nS to the end value nE, and the selection of the estimated image Gi and the product name information corresponding thereto, and the user are known for each user ID. The corresponding memory of the ID is performed, and the question picture material management information I2 as shown in FIG. 13 is constructed.

Fig. 16 is a diagram showing the question screen generation processing in the second embodiment.

In addition, the shopping server 3a' of the second embodiment performs the same processing as the processing shown in FIG. 10 in response to a request from the terminal device, but the difference from the first embodiment is only the step S301. Since the question screen generation processing is performed, only the question screen generation processing in step S301 will be described here.

In FIG. 16, the shopping server 3a' obtains the user ID corresponding to the terminal device that has transmitted the request in step S401, and proceeds to step S601 to select the preference type corresponding to the acquired user ID. Information Ij was obtained.

Then, in the subsequent step S602, the shopping server 3a' selects the display object image Gd used in the question screen based on the preference type information Ij and the question screen material management information I2. In other words, the image ID corresponding to the user ID corresponding to the user ID acquired in step S401 among the user IDs in the challenge picture material management information I2 is selected and displayed on the question screen. The number of image IDs is used as the image ID of the display target image Gd.

Further, the selection of the image ID in step S602 is difficult in order to make the authentication process by the robot difficult, for example, random selection, etc., and is preferably designed such that the same user ID does not select the same image every time.

When the selection process of step S602 is performed, the shopping server 3a' selects a predetermined number of images (image IDs) among the display target images Gd (the image IDs) as the different sense image Gc in step S403. (Image ID), in step S603, processing processing is performed on the strange image target image Gc. That is, the image defined by the image ID of the selected strange image to be imaged Gc in step S403 is obtained from the image DB 3d, and the image processing required to evoke the strange image is performed on the acquired image. The type of image processing to be carried out in step S603 is as described above, and examples thereof include color inversion, upside down, and the like. Further, when the strange image data Gc is a moving image, it also includes processing for causing the moving image to be subjected to slow reproduction, double speed reproduction, or reverse reproduction in the terminal device.

In addition, the image Gc has been selected as the strange object image The types of image processing to be performed by the images are not the same every time, and it is preferable to make the authentication processing by the robot difficult, for example, randomly selecting them to be different each time.

Then, in the subsequent step S604, the shopping server 3a' generates HTML data of the question screen using the processed image, the pre-processed image, and the remaining display target image Gd. In other words, the image subjected to image processing in step S603 among the display target image Gd selected in step S602, the display target image Gd before the image processing, and the remaining display target image Gd are recognized as images. The text information of the meta, the text information as the question text, the text information of the answer option, and the check box cb are the HTML data of the web page set to the predetermined composition, and are generated as the HTML data of the question screen. At this time, the display target image Gd remaining in the above is acquired by the video DB 3d based on the video ID selected in step S602.

In addition, the question screen shown in FIG. 14 is an example in which all of the display target images Gd selected in step S602 are selected as the different sense target image Gc in step S403. In this case, since the "remaining display target image Gd" does not exist, the image Gd is of course not displayed on the question screen.

In accordance with the execution of the processing of step S604, the shopping server 3a' ends the question screen creation processing of step S301.

In addition, in the case of the second embodiment, the method of recognizing the strange image is also known, and the estimated image Gi (display target image Gd) can be used as the first embodiment. Product image in product DB3b. In this case, the image DB 3d shown in FIG. 10 does not need to be specially set.

In addition, in the above, as the known estimated image Gi (display target image Gd), the image of the type that is preferred by the user is selected and displayed on the question screen, but the estimated image Gi may be known. As exemplified in the first embodiment, it is selected based on the action history information. For example, there is an image of a product that browses a history or a purchase history, an image of a product that has been placed in a shopping basket, an image of a product that has been bookmarked, and the like.

[2-3. Summary of the second embodiment]

As described above, in the information processing device (shopping server 3a') of the second embodiment, it is managed for each user identification information: the type of tendency preferred by the user defined by the user identification information. The information selection unit (image selection processing unit F2') is a preference for the user's preference among the images in the memory unit (image DB3d) that are managed and stored for each type of image. The image to which the type of the type is the same is selected as the estimated estimated image, and one or a plurality of known estimated images are selected as the display target image.

Thereby, as the known estimated image, an image other than the image actually estimated by the user is selected.

Therefore, it is possible to increase the number of options for displaying the display target image displayed on the screen, and it is possible to increase the change of the challenge screen, and it is difficult to solve the authentication process by the robot.

Further, in the information processing device of the second embodiment, the display control unit (display control processing unit F3') selects one or a plurality of user-related images that are moving images as display target images.

Thereby, a moving image is displayed as a display target image in the question screen.

When the computer program that is a robot analyzes the display target image on the question screen to display it, it is displayed when the target image is a moving image, and the target image is a still image. It takes more time to analyze and so on, which makes analysis more difficult. Therefore, the cracking of the authentication process by the robot can be made more difficult, and the authentication accuracy can be further improved.
