Description

  The present invention relates to a service system for executing a predetermined process using a cookie and a password, the service system including an electronic device and a server device that provides the service to the electronic device, and a method thereof.

  Currently, a service system including an electronic device and a server device that provides services to the electronic device is widely spread, and various types of services such as providing life information and selling products through online shopping are provided.

  In providing such a service, it is necessary for the server device to be able to recognize the electronic device and to recognize that the electronic device is being used by a genuine user. Generally, cookies and passwords are used as a mechanism for this purpose.

  A cookie generally refers to an information file transmitted from a Web server and stored on the hard disk of a terminal on which a Web browser is operating. For example, a device for identifying an electronic device as the content recorded in the file Since the ID is included and the fact that the cookie has already been sent to the electronic device identified by the device ID or the like is recorded on the server device side, the server device can identify the electronic device by such a mechanism. It becomes. The password is used to prevent leakage of personal information, and generally a number string, code string, etc. known only to the user of the electronic device are used. As a result, the server device can identify the electronic device and its user, and the same user can receive service from the server device using the same electronic device.

For example, Patent Document 1 discloses a system and method for performing electronic commerce while performing authentication using a cookie and a password.
Japanese translation of PCT publication No. 2003-508838

  By the way, an electronic device can be used by a third party other than a genuine user to illegally access the server device, fail and become unrepairable, or disposed of as a new device. There are cases in which a transfer to (replacement) is made. In this case, the same user is transformed into a form in which service is provided from the server device using the same electronic device. For example, in the case of unauthorized access by a third party, the electronic devices are the same, but the users are different. In this case, if the unauthorized user tries to receive a service related to personal information from the server device using the electronic device, the electronic device stores the cookie normally. This is recognized as a genuine device. However, since the password is set for the user and the personal information cannot be accessed unless the authentic password is inserted, the server device can be accessed from the authentic user even if an unauthorized accessor inputs an incorrect password. Recognize that it is not an access and perform a process that does not provide the service. As a result, the personal information is prevented from leaking. Then, for example, a method may be employed in which an electronic device is locked when an incorrect password is input a certain number of times, and the electronic device cannot be used unless an unlocking measure is taken thereafter. In the case of transfer to a new device, the user is the same, but the electronic device is changed. Therefore, naturally, since the new electronic device communicates with the server device for the first time, the electronic device newly acquires a cookie. Since the association between the electronic device and the personal information is also disconnected, the user is recognized as a new user for the electronic device, and a new password is issued. In other words, in this case, the password previously used by the user is not taken over and the service is provided as a completely new user.

  As described above, there are various patterns when the electronic device or its user is changed. At present, the server apparatus is suitable for each case by appropriately responding to these patterns and appropriately responding to the needs of the user by the server device. A mechanism for providing (or not) providing services has not been established. In particular, when transferring to a new device, it is necessary to receive a service as a completely new user without passing over the password that the user has previously used, even though the user is the same. This is inconvenient for the user.

  Accordingly, the problem to be solved by the present invention is that the server apparatus responds finely to these patterns according to various patterns when the electronic device or its user changes, and the server device makes an appropriate judgment while responding to the user's needs. It is to provide a mechanism for providing (or not) providing a service suitable for the case. In particular, in the case of switching to a new device, the inconvenience for the user that the user needs to be provided with a service as a completely new user is eliminated.

  In order to solve the above problems, the present invention is a service system including an electronic device and a server device that provides a service to the electronic device, and the electronic device is device identification information that is identification information unique to the electronic device. Device identification information holding unit, a cookie holding unit that holds a cookie that is information indicating whether or not communication with the server device has been performed in the past, and password information input for inputting password information to be sent to the server device Unit, a control unit, and an electronic device communication unit for exchanging information with the server device. The server device provides services to the electronic device with the server device communication unit for exchanging information with the electronic device. An information acquisition and registration unit that registers information sent from electronic devices as electronic device information in units of electronic devices so that they can be provided, and the electronic devices try to receive services The device identification information comparison unit that compares the device identification information sent to the device and the device identification information stored in the information storage unit, and when the electronic device attempts to receive a service, obtains an appropriate cookie from the electronic device A cookie determination unit that determines whether the electronic device is ready to receive a service, a password information comparison unit that compares password information that is transmitted when the electronic device attempts to receive a service, and password information that is stored in the information storage unit, A service system having a process execution unit that executes a process determined based on a result, and an operation method of a server device of the system are provided.

  As described above, the service system according to the present invention uses the device identification information, the cookie, and the password information unique to the electronic device, and the information sent from the electronic device and the information registered and stored in the server device. Etc., and perform predetermined processing based on the results. Therefore, according to various patterns when electronic devices or their users are changed, these patterns are finely supported and user needs It is possible to provide a mechanism for the server apparatus to provide (or not perform) a service suitable for each case by making an appropriate determination while supporting the above. In particular, in the case of switching to a new device, it is possible to eliminate the inconvenience for the user that the user needs to receive service provision as a completely new user.

  <Configuration>

  FIG. 1 is a diagram illustrating an example of functional blocks of the service system according to the present embodiment. Each unit, which is a component of the present invention, is configured by either hardware, software, or both hardware and software. For example, as an example for realizing these, when a computer is used, hardware composed of a CPU, a memory, a bus, an interface, peripheral devices, and the like, and software executable on these hardware are listed. Can do.

  Specifically, the functions of the respective units are realized by sequentially executing the programs developed on the memory, by processing, storing, and outputting data on the memory and data input through the interface. Functions of each part are realized by data processing, storage, and output.

  In the figure, the “service system” 0100 of the present embodiment includes an “electronic device” 0110 and a “server device” 0120. Among these, the electronic device includes a “device identification information holding unit” 0111, a “cookie holding unit” 0112, a “password information input unit” 0113, a “control unit” 0114, and an “electronic device communication unit” 0115. Have.

  The “device identification information holding unit” is configured to hold device identification information that is identification information unique to an electronic device. The “device identification information” may be, for example, the device manufacturing number of the Internet terminal device as long as it is identification information uniquely (as a unique) for each device, or attached separately from the device manufacturing number. It may be done. In either case, the device identification information may be unique in the world, or may be unique only within the scope of a server constituting the network including the device. Further, it is desirable that the device identification information has a structure in which the contents are not easily seen from the outside, that is, a structure held in the tamper-resistant region.

  The “cookie holding unit” is configured to hold a cookie that is information indicating whether the server apparatus has communicated with the server in the past. A cookie generally refers to an information file transmitted from a Web server and stored on the hard disk of a terminal on which a Web browser is operating. However, the cookie is limited to this meaning. Further, the information is information that can be identified by the server device itself that transmitted the cookie.

  The “password information input unit” is for inputting password information to be sent to the server device. The password is used to prevent leakage of personal information, and generally refers to a number sequence, code sequence, etc. known only to the user of the electronic device.

  With the configuration of the cookie holding unit and the password information input unit as described above, the server device is a genuine device that the electronic device has surely communicated with itself in the past, and the electronic device is confirmed by the password. Since it can be recognized that the electronic device is used by an authentic user, the electronic device can receive a service from the server device as an authentic electronic device used by the authentic user.

  The “control unit” is configured to perform control. The “control” here includes a wide range of processing necessary for the electronic device to receive service provision from the server device. For example, the device identification information held in the device identification information holding unit is sent to the server device, the cookie is sent to the server device, and the password information input in the password information input unit is sent to the server device. For example.

  The “electronic device communication unit” is for exchanging information with the server device. Specifically, the electronic device communication unit is configured to enable communication with the server device. Thereby, transmission of the above-mentioned device identification information and password information and transmission / reception of a cookie become possible. In addition, it becomes possible for the electronic device to receive a service from the server device. Here, the information related to the service that is an object that the electronic device can communicate with is information related to the service using personal information. Specifically, for example, it is conceivable that information related to an online shopping service using automatic debit from a bank deposit course, automatic payment by credit card, or the like is a communicable target. In this case, the bank account number or credit card number corresponds to the personal information. In addition, information relating to distribution services for movies, music, etc. using such a payment method, broadcasting services for pay broadcasting and pay cable broadcasting, services for providing living information such as weather forecasts and shopping information, etc. may be targeted for communication. Conceivable. Alternatively, only information related to a billing service using personal information related to the provision of these contents may be considered as a communicable target. In order to prevent personal information from being misused by others in the service using such personal information and improper transfer by impersonation, etc., device identification information, cookies, and password information are used. That is, these pieces of information are transmitted and received between the electronic device and the server device, and based on the result of the server device comparing and judging these pieces of information, the electronic device is authentic, and the subject relating to the personal information and the electronic device Such misuse can be prevented by configuring so that the service can be provided from the server device only when the identity with the subject user is confirmed.

  Next, the “server device” includes a “server device communication unit” 0121, an “information acquisition registration unit” 0122, a “device identification information comparison unit” 0123, a “cookie determination unit” 0124, and a “password information comparison unit”. "0125" and "Processing execution unit" 0126.

  The “server device communication unit” is for exchanging information with an electronic device. Specifically, the server device communication unit is configured to enable communication with the electronic device. Thereby, the above-described device identification information and password information can be received and cookies can be transmitted and received. In addition, the server device can provide services to the electronic device. Here, the service that is the target that the server apparatus can communicate with is a service that uses personal information. Specifically, the example given in the above description of the electronic device communication unit can be considered. As described above, device identification information, cookies, and password information are used in order to prevent personal information from being misused by others in the service that uses such personal information and improper transfer due to impersonation. The That is, these pieces of information are transmitted and received between the electronic device and the server device, and based on the result of the server device comparing and judging these pieces of information, the electronic device is authentic, and the subject relating to the personal information and the electronic device Such misuse can be prevented by configuring the server apparatus to provide the service only when the identity with the subject user is confirmed.

  The “information acquisition / registration unit” is configured to register information sent from an electronic device as electronic device information in units of electronic devices so that a service can be provided to the electronic device. Here, information sent from an electronic device and registered as electronic device information in units of electronic devices includes device identification information and password information. However, it is not essential that all these pieces of information are included. For example, password information may not be included. In addition, the “electronic device” referred to herein as “information sent from the electronic device” may be the same device as the electronic device to which the service is provided or may be a different device. As an example of the latter, for example, in the case of device transfer, it is possible to transfer from the old device to the new device using a special password (the specific contents will be described later) transmitted from the old device. Therefore, there is a case where the password information is transmitted from the old device.

  The “device identification information comparison unit” is configured to compare the device identification information transmitted when the electronic device attempts to receive a service with the device identification information stored in the information acquisition registration unit. This comparison is a comparison of whether the device identification information sent from the electronic device matches the device identification information stored in the information acquisition registration unit. Note that the “match” here may include all matches as well as some matches. For the latter, for example, when the device identification information is composed of a part used by the user, a part used by the manufacturer, a part specifying the CP and the service provided by the user, the device identification information comparison unit For example, it is possible to compare whether or not only the portions to be used match.

  The “cookie determination unit” is configured to determine whether an appropriate cookie has been acquired from the electronic device when the electronic device is to receive a service. This determination is made, for example, in advance when the server device first communicates with the electronic device, the server device sends a cookie to the electronic device, and the server device transmits the cookie to the electronic device. This is done by determining whether or not the cookie sent from the electronic device is appropriate in light of the history information, assuming that the information is retained.

  The “password information comparison unit” is configured to compare the password information transmitted when the electronic device attempts to receive a service with the password information stored in the information acquisition registration unit. This comparison is a comparison of whether or not the password information sent from the electronic device matches the password information stored in the information acquisition registration unit.

  The “process execution unit” is configured to execute a process determined based on the result of each unit. More specifically, “execute a predetermined process” means that a process for providing a service to an electronic device is executed according to a result of the comparison / determination in each unit, or an electronic device is The processing to disable the service is executed, the processing to register the electronic device information is executed, and the device identification information included in the electronic device information including the password information that matches the comparison result is compared. For example, the registration processing is executed by replacing the device identification information that the results do not match. For example, if the comparison result in the device identification information comparison unit is the same, the determination result in the cookie determination unit is the appropriate determination result, and the comparison result in the password information comparison unit is the same. In the case of the comparison result, the process execution unit executes a process for providing a service to the electronic device.

  Next, a system configuration of a service system for enabling such processing execution will be described.

  FIG. 2 is a diagram illustrating an example of a system configuration from the hardware viewpoint of the server device of the service system. In the figure, a CPU 0201, a main memory 0202, a memory 0203, a communication interface 0204, and an I / O 0205 bus line 0206 are connected. The memory stores device identification information 0207 sent in advance from the electronic device, history information 0208 for sending cookies to the electronic device, and password information 0209 sent from the electronic device. These pieces of information may be stored in an external storage device such as an HDD. In addition, the main memory compares the device identification information stored in the memory and the like with the device identification information transmitted from the electronic device and acquired by the server device using the interface and I / O, and is stored in the memory or the like. Judgment of cookie based on history information of cookie transmission and comparison of password information stored in memory etc. with password information sent from electronic device and acquired by server device using interface and I / O, A control program for executing processing according to the result is developed. This program is, for example, a process list table 0211 based on each comparison / judgment result. For example, if the result is A, the process based on Program 1 is executed, and if the result is B, Program 2 is executed. This is a program for instructing that processing can be performed according to a table in which results and instructions based thereon are associated with each other. Specifically, for example, the result A is a comparison result that the comparison result of the device identification information matches, a determination result that the determination result of the cookie is appropriate, and a comparison result that the comparison result in the password information comparison unit matches. Yes, Program 1 associated therewith is a process for executing a process for providing a service to an electronic device. When an information request is sent from the electronic device together with device identification information and password information, and execution of the control program is requested, processing according to the instruction of the control program developed in the main memory is executed by the CPU. That is, first, the device identification information sent from the electronic device is compared with the device identification information stored in the memory, etc., the cookie is judged based on the history information of the cookie transmission stored in the memory, etc., and sent from the electronic device. The password information stored in the memory or the like is compared. Further, processing corresponding to the comparison / determination result is executed. For example, when the comparison / determination result is A, a process based on Program 1 is executed and output.

  As is apparent from the above description, in the system configuration of the server apparatus of this example, the acquisition performed by the information registration acquisition unit is performed via the communication interface, and the registered information is stored in a memory or the like. In addition, the processing execution based on the comparison / judgment performed by the device identification information comparison unit, the cookie judgment unit, the password information comparison unit, and the processing execution unit when the service is provided after registration is performed by the CPU using a memory or the like. Done.

  FIG. 3 shows a procedure for registering information sent from an electronic device as electronic device information in units of electronic devices so that the server apparatus can provide services to the electronic devices. (2) The server device compares and determines the device identification information, cookie and password information sent from the electronic device when receiving the service, based on the information registered as described above, and executes the processing. It is the conceptual diagram demonstrated using an example for the example of the point to perform.

  First, an example of a procedure for registering information sent from an electronic device as electronic device information in units of electronic devices so that the server apparatus can provide services to the electronic device will be described. In the example shown in the figure, the electronic device A holds “XYZ001” as device identification information. When the user first communicates with the server device B using the electronic device A, a screen for prompting the user to input password information is transmitted from the server device B to the electronic device A, and the electronic device A Inputs password information “7890” set by the user. Then, the electronic device A sends the device identification information “XYZ001” and the password information “7890” to the server device B. In response to this, the server apparatus B acquires and registers the device identification information “XYZ001” and password information “7890” sent from the electronic device A. With this registration, a cookie “a” that is information indicating that the electronic device has communicated with the server device B is sent from the server device B to the electronic device A. Hold. On the other hand, the server device holds history information “b” indicating that the cookie “a” has been transmitted to the electronic device A. Unlike the above example, transmission of a screen or the like for prompting input of password information from the server device B to the electronic device A is performed when the server device B determines that the user of the device already has a password, for example. It may be configured to perform only. In this case, it is a matter of course that the processing following the input of password information is not performed, and another processing (for example, processing for disabling service provision) is performed. As a result of the above, the device identification information “XYZ001” and password information “7890” are registered and stored in the server apparatus B, and “b”, which is transmission history information of the cookie “a”, is held. become.

  Next, when the electronic device tries to receive service, the server device compares and judges the device identification information, the cookie, and the password information sent from the electronic device based on the information registered as described above, and executes the processing. An example of the procedure to be performed will be described. When the user of the electronic device A wants to receive a service for providing information “C” from the server device using the electronic device A, as shown in FIG. Along with this information request, the device identification information “XYZ001”, the cookie “a”, and the password “7890” are transmitted to the server apparatus B. Then, the server apparatus B compares the transmitted device identification information “XYZ001” with the registered and accumulated device identification information “XYZ001”. In this example, a comparison result that the two match is obtained. Further, the server device B determines whether or not the transmitted cookie “a” is appropriate in light of the transmission history information “b”. In this example, a determination result that the cookie “a” acquired from the electronic device A is appropriate is obtained. Further, the server apparatus B compares the transmitted password “7890” with the registered and accumulated password “7890”. In this example, a comparison result that the two match is obtained. As a result, the server apparatus B provides the service by transmitting “C” information related to the request to the electronic device A.

  In the above example, the server device acquires and registers the device identification information and password information used for comparison with the device identification information and password information transmitted from the electronic device, which are sent from the electronic device to the server device. , Explained with an example of what accumulates. However, other embodiments are possible. That is, if the device identification information and password information used for the comparison are configured to be registered in advance, the server device is configured to acquire, register, and store the information by other methods. Also good. For example, these pieces of information are mailed from the user of the electronic device to the administrator of the server device, and based on this, the administrator of the server device directly inputs these information to the server device. The information may be acquired and registered.

  <Process flow>

  FIG. 4 is a diagram illustrating an example of a processing flow in the service system of the present embodiment.

  First, in electronic device information registration step S0401, the service system registers information sent from the electronic device as electronic device information for each electronic device so that the service can be provided to the electronic device. Information sent from the electronic device includes device identification information and password information. However, it is not essential that all these pieces of information are included. For example, password information may not be included. In addition, when password information is included, the information is input to the electronic device and sent based on an input prompt from the server device to the electronic device.

  Next, in the device identification information sending step S0402, the service system sends the device identification information from the electronic device to the server device when the electronic device is to receive a service.

  Next, in cookie sending step S0403, the service system sends a cookie from the electronic device to the server device when the electronic device is to receive a service.

  Next, in the password information sending step S0404, the service system sends password information from the electronic device to the server device when the electronic device tries to receive a service.

  Note that the processing in the device identification information transmission step, the cookie transmission step, and the password information transmission step does not necessarily have to be performed in this order, and may be performed in any order. In addition, it is not essential that the processing is performed in all steps, and some of the steps may be missing. For example, the password information may not be sent because the password information is not sent from the electronic device when the electronic device tries to receive a service.

  Next, in the device identification information comparison step S0405, the service system is registered and stored in the electronic device information registration step and the device identification information sent from the electronic device when the electronic device is to receive service. Compare the device identification information.

  Next, in cookie determination step S0406, the service system determines whether or not an appropriate cookie has been acquired from the electronic device when the electronic device is to receive the service. The determination is made, for example, by checking a cookie sent from the electronic device with history information held in the server device.

  Next, in the password information comparison step S0407, the service system uses the password information transmitted from the electronic device when the electronic device is to receive service and the password information registered in the electronic device information registration step. Compare.

  Note that the processing in the device identification information comparison step, the cookie determination step, and the password information comparison step does not necessarily have to be in this order, and may be in any order. In addition, it is not essential that the processing is performed in all steps, and some of the steps may be missing. For example, since the password information is not sent from the electronic device when the electronic device tries to receive a service, the password information comparison step may be omitted.

  Further, in the process execution step S0408 for executing the acquisition of the result in each step and the predetermined process based on the result, the service system includes the device identification information comparison step, the cookie determination step, and the password information comparison step. A result is acquired and the process defined based on the result is executed. For example, a comparison result that the comparison result in the device identification information comparison step matches, a comparison result that the determination result in the cookie determination step is appropriate, and a comparison result in the password information comparison step matches If it is a result, the result is acquired, and processing for providing a service to the electronic device is executed based on the result. This process is, for example, a process list table based on the comparison / determination result in each step in the server device of the service system. For example, if the result is A, the process based on Program 1 is executed, and if the result is B, This is performed according to a table in which a result and a command based on the result are associated with each other in the form of executing Program2. Specifically, for example, when a result of A is obtained in each of the above steps, the program 1 stored in the storage memory is expanded to the execution memory in order to perform the process according to the program 1 based on this. The CPU executes processing according to Program1.

  <Effect>

  The service system of this embodiment uses device identification information, cookies, and password information unique to the electronic device, and compares and determines the information sent from the electronic device and the information registered and stored in the server device. However, by executing a predetermined process based on the result, the server apparatus can respond to these patterns finely according to various patterns when the electronic device or the user is changed, while responding to the needs of the user. It is possible to provide a mechanism for (or not) providing a service suitable for each case by appropriate judgment.

  <Overview>

  The service system of the present embodiment is a comparison result that the comparison result of the device identification information matches, a determination result that the determination result of the cookie is appropriate, or a comparison result that the comparison result in the password information comparison unit does not match In this case, processing for disabling the provision of services to electronic devices is executed. When the electronic devices themselves are authentic, it is possible to cope with unauthorized access by others other than genuine users. It is assumed.

  <Configuration>

  FIG. 5 is a diagram illustrating an example of functional blocks of the service system according to the present embodiment. In the drawing, the “service system” 0500 of the present embodiment includes an “electronic device” 0510 and a “server device” 0520. Among them, the electronic device includes “device identification information holding unit” 0511, “cookie holding unit” 0512, “password information input unit” 0513, “control unit” 0514, and “electronic device communication unit” 0515. Have. The “server device” includes “server device communication unit” 0521, “information acquisition registration unit” 0522, “device identification information comparison unit” 0523, “cookie determination unit” 0524, and “password information comparison unit”. 0525 and a “process execution unit” 0526.

  The “process execution unit” of the “server device” includes a comparison result that the comparison result in the device identification information comparison unit matches, a determination result that the determination result in the cookie determination unit is appropriate, and a password information comparison unit When the comparison result indicates that the comparison results do not match, a process for disabling the provision of service to the electronic device is executed. The comparison result that the comparison result in the device identification information comparison unit does not match, the determination result that the determination result in the cookie determination unit is inappropriate, or the comparison result that the comparison result in the password information comparison unit matches In this case, the process execution unit is configured to execute a process other than the above that is determined based on the result of each unit.

  Since the rest of the configuration is the same as the configuration of the service system of the first embodiment, a description thereof will be omitted.

  Such a configuration includes, for example, a service related to personal information of a user by impersonating a person other than the genuine user who impersonates the genuine user of the electronic device, including when the electronic device is stolen. (E.g., shopping at a pre-registered shopping site so that the user can be debited from the bank account by entering a password). That is, in this case, since the electronic device itself is authentic, if an unauthorized access person operates the electronic device to access the server device, the comparison result in the device identification information comparison unit of the server device matches. As a result of comparison, the determination result in the cookie determination unit is also determined to be appropriate. However, as for the password, since the authentic password cannot be entered unless an unauthorized accessor obtains the authentic user password separately, the comparison result in the password information comparison unit of the server device does not match. It becomes. In this case, since the process execution unit is configured to execute a process for disabling service provision, an unauthorized accessor pretends to be a genuine user, and the service related to the personal information of the user The situation of receiving provision can be prevented.

  The “process for disabling service” corresponds to, for example, a process of locking the function of the device so that subsequent electronic device operations cannot be performed. In this case, in order to release the lock, for example, it is necessary to separately apply to the server device administrator using information (such as a genuine password) that only a genuine user can know. Preventing unauthorized processing by the accessor is guaranteed. As an example of locking and unlocking, if illegal password information is input a certain number of times, the I / O function of the electronic device is partially stopped (for example, input using a keyboard or mouse becomes impossible). In order to cancel this, it is conceivable that a signal that only a genuine user and an administrator of the server device can know must be input to the electronic device.

  <Process flow>

  FIG. 8 is a diagram illustrating an example of the flow of processing in the service system of the present embodiment.

  In the process execution step S0808 for providing a service to the electronic device, the service system determines that the comparison result in the device identification information comparison step S0805 is the same, and the determination result in the cookie determination step S0806 is appropriate. If the result of the determination is that the comparison results in the password information comparison step S0807 match, a process for providing a service to the electronic device is executed. If the comparison result in the device identification information comparison step does not match, the determination result in the cookie determination step is incorrect, or the comparison result in the password information comparison step does not match In the predetermined process execution step S0809, the service system executes processes other than those described above based on the results in the respective steps.

  The rest of the processing flow is the same as the processing flow in the service system according to the first or second embodiment, and a description thereof will be omitted.

  <Effect>

  The service system according to the present embodiment enables a user of an electronic device to receive a service from a server device using a normal state, that is, a cookie and password information.

  <Overview>

  The service system according to the present embodiment registers the electronic device information in the server device when the comparison result that the device identification information comparison results do not match and the determination result of the cookie is inappropriate. This processing is executed, and it is assumed that it is possible to cope with cases such as new purchase of electronic equipment. At this time, in order to distinguish from the processing in the embodiment that assumes the later-described transfer, for example, the presence / absence of password information is determined, and the processing is executed when there is no password information.

  <Configuration>

  FIG. 9 is a diagram illustrating an example of functional blocks of the service system according to the present embodiment. In the figure, the “service system” 0900 of this embodiment includes an “electronic device” 0910 and a “server device” 0920. Among them, the electronic device includes “device identification information holding unit” 0911, “cookie holding unit” 0912, “password information input unit” 0913, “control unit” 0914, and “electronic device communication unit” 0915. Have. The “server device” includes “server device communication unit” 0921, “information acquisition registration unit” 0922, “device identification information comparison unit” 0923, “cookie determination unit” 0924, and “password information comparison unit”. 0925 and a “process execution unit” 0926.

  The “process execution unit” of the “server device” is an electronic device if the comparison result in the device identification information comparison unit is not the same, or the determination result in the cookie determination unit is an inappropriate determination result. It is configured to execute processing for registering device information in the information acquisition and registration unit of the server device. “Registration process” refers to a process for prompting an electronic device to register. Specifically, for example, a registration format is input to the electronic device, a user password is input to the format, and the server This includes processing such as sending a message prompting the device to reply. As a result, when password information is sent back together with the device identification information from the electronic device, the information acquisition / registration unit of the server device can acquire them and register them as electronic device information in units of electronic devices. When the registration is completed, the server device sends a cookie to the electronic device, and holds sending history information related to the cookie. As a result, when there is an information request for providing the service from the electronic device thereafter, the server apparatus can provide the service related to the above processing execution. Service provision after registration is completed is performed according to the description in the other embodiments. If the comparison result in the device identification information comparison unit is the same as the comparison result, or the determination result in the cookie determination unit is a determination result that is appropriate, the process execution unit determines the result in each unit. It is comprised so that the process other than the above defined based on this may be performed.

  This configuration is based on the premise that the device identification information once registered by the server device is kept without being erased thereafter. For this reason, since the server device is a comparison result that the comparison result in the device identification information comparison unit does not match, the electronic device has never been registered in the server device, that is, completely new to the server device. It is possible to know that the device is an electronic device, and it is possible to execute a process for prompting registration, which is an appropriate process in this case. In other words, in the light of social significance, when a user accesses for the first time using a newly purchased electronic device to receive a service using personal information, it is necessary to provide such a service. Where registration is required in association with personal information and device identification information, it can be said that the processing of this example is a process for that purpose.

  Further, as described later, even if the comparison result in the device identification information comparison unit does not match, even if the determination result in the cookie determination unit is inappropriate, the password information comparison unit Based on the comparison result in, a process different from the process for registering the electronic device information in the information acquisition / registration unit of the server device may be performed. Therefore, in order to be able to accurately distinguish between such cases, the server device of the present embodiment is a comparison result that the comparison result in the device identification information comparison unit matches, or the determination result in the cookie determination unit is appropriate. In the case of the determination result, it is desirable to have means for determining the presence or absence of password information. In this case, if the comparison result in the device identification information comparison unit is the same, or the determination result in the cookie determination unit is appropriate, the presence or absence of password information performed by the means When the determination result regarding “no password information” is obtained, the process execution unit executes the process for registering the electronic device information in the information acquisition registration unit of the server device for the first time. In addition, when the result of determination regarding the presence or absence of password information is a result of “password information present” and the comparison result in the password information comparison unit is the same, the electronic information including the password information with the same comparison result is obtained. The device identification information included in the device information is replaced with the device identification information for which the comparison result does not match, and the process for registration is executed. If the comparison result indicates that the comparison result in the password information comparison unit does not match, the processing different from the above may be performed.

  The determination of the presence / absence of password information in these cases is specifically based on, for example, a comparison result indicating that the comparison results regarding the device identification information do not match and a determination result regarding the cookie being inappropriate. It is possible that the device can determine that there is no password information by sending a question “whether it is new registration or transfer” to the electronic device and obtaining an answer that selects “new registration”. .

  The rest of the configuration is the same as the configuration of any one of the service systems according to the first to third embodiments, and a description thereof will be omitted.

  In such a configuration, for example, when a user of an electronic device newly purchases an electronic device, a password that has not yet been set is set, and a new service is provided from the server device using the electronic device. Make it possible.

  <Process flow>

  FIG. 10 is a diagram illustrating an example of a processing flow in the service system of the present embodiment.

  In the processing execution step S1007 for registering the electronic device information in the server device, the service system determines that the comparison result in the device identification information comparison step S1005 does not match, and the determination result in the cookie determination step S1006. When it is determined that the information is inappropriate, processing for registering information about the electronic device in the server device is executed. In the case where the comparison result in the device identification information comparison step is the same as the comparison result or the determination result in the cookie determination step is an appropriate determination result, in the predetermined process execution step S1008, the service system Processing other than the above determined based on the result in the step is executed.

  In addition, as described above, even if the comparison result in the device identification information comparison step does not match and the determination result in the cookie determination step is inappropriate, the password information comparison step further If the comparison result indicates that the comparison results match, a process different from the process for registering the electronic device information in the information acquisition / registration unit of the server device may be performed. So that the server device of the present embodiment further includes a comparison result that the comparison result in the device identification information comparison step does not match and a determination result in the cookie determination step is an inappropriate determination result. It is desirable to perform processing in the step of determining whether or not there is password information. Specifically, if the comparison result in the device identification information comparison step does not match and the determination result in the cookie determination step is an inappropriate determination result, (1) next to the electronic device Processing in the step of determining the presence or absence of password information is performed, and if the determination result is “no password information”, processing for registering information on the electronic device in the server device is executed. (2) Next, the electronic device Is processed in the step of determining whether or not there is password information, and if the determination result is “password information is present”, the process further proceeds to the password information comparison step. The device identification information included in the electronic device information including the password information that matches the comparison result is the device identification information that does not match the comparison result. Execute processing for replacement and registration. (3) Next, processing is performed in the step of determining whether or not there is password information for the electronic device. If the determination result is “with password information”, password information comparison is further performed. In the step, when the comparison result indicates that the comparison result does not match, there are three patterns in which processing different from the above is performed.

  The remaining processing flow is the same as the processing flow in the service system according to any one of the first to third embodiments, and thus the description thereof is omitted.

  <Effect>

  With the service system of the present embodiment, the user of the electronic device can newly set a password in a form prompted by the server device and can receive service from the server device.

  <Overview>

  The service system of this embodiment has a comparison result that the comparison result of the device identification information does not match, a determination result that the determination result of the cookie is inappropriate, and a comparison result that the comparison result of the password information matches. The device identification information included in the electronic device information including the password information that matches the comparison result is replaced with the device identification information that is determined not to match the comparison result, and a process for registering the device identification information is executed. It is assumed to cope with the case of transfer or failure. The replacement here is to replace the device identification information of the old device (device before transfer) associated with the personal information with that of the new device (device after transfer).

  <Configuration>

  FIG. 11 is a diagram illustrating an example of functional blocks of the service system according to the present embodiment. In the drawing, a “service system” 1100 of the present embodiment includes an “electronic device” 1110 and a “server device” 1120. Among them, the electronic device includes “device identification information holding unit” 1111, “cookie holding unit” 1112, “password information input unit” 1113, “control unit” 1114, and “electronic device communication unit” 1115. Have. The “server device” includes a “server device communication unit” 1121, an “information acquisition registration unit” 1122, a “device identification information comparison unit” 1123, a “cookie determination unit” 1124, and a “password information comparison unit”. 1125 and a “process execution unit” 1126.

  The “process execution unit” of the “server device” is a comparison result that the comparison result in the device identification information comparison unit does not match, a determination result that the determination result in the cookie determination unit is inappropriate, and a password information comparison unit If the comparison results indicate that the comparison results match, the device identification information included in the electronic device information including the password information that matches the comparison results is replaced with the device identification information that is determined not to match. It is comprised so that the process for performing may be performed. In addition, it is a comparison result that the comparison result in the device identification information comparison unit matches, a determination result that the determination result in the cookie determination unit is appropriate, or a comparison result that the comparison result in the password information comparison unit does not match In some cases, the process execution unit is configured to execute a process other than the above, which is determined based on the results of the respective units.

  Since the remaining configuration is the same as that of any one of the service systems according to the first to fourth embodiments, the description thereof is omitted.

  Such a configuration makes it possible, for example, when a user of an electronic device changes (purchases) from an old electronic device to a new electronic device, compared with a case where registration of a new device is completely new. Specifically, the user had password information when using the old device to receive the service, but it would be more convenient to continue using the same password information when switching to the new device. It is. Therefore, the service system according to the present embodiment is configured to execute a process for realizing transfer when the password sent from the new device matches the password used in the old device. That is, in this case, when the password information that has been used conventionally is sent from the new device among the information sent from the new device, the comparison / judgment result in the server device indicates that the device identification information is the new device. Therefore, it does not match the device identification information of the registered old device, and the new device has never communicated with the server device in the past, so the cookie judgment result is also incorrect, but only the password information is old. Since the registered password information is sent, the comparison results match. Therefore, the server apparatus can recognize from the password information comparison result that this user is a registered user and a person who has changed the device. Therefore, the server device can cut off the association between the device identification information of the old device and the password information and newly register the password information in association with the device identification information of the new device. Specifically, the device identification information registered in association with the password information (the device identification information of the old device) is replaced with the device identification information (the device identification information of the new device) sent this time for registration. As a result, the user can use the password information used on the old device as it is on the new device to receive service, and a system suitable for the convenience of the user can be realized.

  In the service system of this embodiment, if only the passwords match, the transfer from the old device to the new device is realized, so there is a risk of unauthorized access by others due to leakage or accidental matching of the password. It is necessary to avoid it strictly. For this reason, for example, a special password used exclusively for such a transfer is provided, and the special password is associated with the device identification information of the old device together with the device identification information of the new device. It is desirable to be able to confirm that the person accessing from the new device is definitely the user of the old device by sending a password. In addition, it is desirable that the special password at that time is longer than a normal password (the number of numbers and symbols is large) in order to minimize the chance of coincidence.

  In addition, the configuration of the service system of the present embodiment is that the user continued to use the old device (failed device) even when, for example, the electronic device failed to be repaired and was replaced with a new device. It is also possible to receive services by using the password information as it is on the new device (the device after replacement).

  <Process flow>

  FIG. 12 is a diagram illustrating an example of a processing flow in the service system of the present embodiment.

  In the processing execution step S1208 for registering the device identification information included in the electronic device information including the password information with the comparison result matching the device identification information with the comparison result not matching, the service system A comparison result that the comparison result in the identification information comparison step S1205 does not match, a determination result that the determination result in the cookie determination step S1206 is inappropriate, and a comparison result that the comparison result in the password information comparison step S1207 matches. In this case, the device identification information included in the electronic device information including the password information with the matching comparison result is replaced with the device identification information with which the comparison result does not match, and processing for registration is executed. If the comparison result in the device identification information comparison step is the same, the determination result in the cookie determination step is appropriate, or the comparison result in the password information comparison step is not the same In the predetermined process execution step S1209, the service system executes processes other than those described above based on the results in the respective steps.

  Since the remaining process flow is the same as the process flow in any one of the service systems according to the first to fourth embodiments, the description thereof will be omitted.

  <Effect>

  With the service system of the present embodiment, the user of the electronic device can receive the service by using the password information used in the old device as it is in the new device in the case of a transfer or failure of the electronic device, A system suitable for the convenience of the user can be realized.

  <Overview>

  In the service system of the present embodiment, if the comparison result in the device identification information comparison unit is the same and the determination result in the cookie determination unit is a determination result that is inappropriate, the process execution unit This is a process that prompts the server to send information to be registered so that services can be provided to the device, and is intended for use when second-hand products of other people's electronic devices are used. is there.

  <Configuration>

  FIG. 13 is a diagram illustrating an example of functional blocks of the service system according to the present embodiment. In the drawing, a “service system” 1300 according to the present embodiment includes an “electronic device” 1310 and a “server device” 1320. Among these, the electronic device includes a “device identification information holding unit” 1311, a “cookie holding unit” 1312, a “password information input unit” 1313, a “control unit” 1314, and an “electronic device communication unit” 1315. Have. The “server device” includes “server device communication unit” 1321, “information acquisition registration unit” 1322, “device identification information comparison unit” 1323, “cookie determination unit” 1324, and “password information comparison unit”. 1325 and a “process execution unit” 1326.

  The “process execution unit” of the “server device” is an electronic device if the comparison result in the device identification information comparison unit is the same and the determination result in the cookie determination unit is an inappropriate determination result. It is configured to execute a process for prompting transmission of information to be registered to the server device so that a service can be provided to the device. If the comparison result in the device identification information comparison unit does not match or the determination result in the cookie determination unit is appropriate, the process execution unit determines whether the result in each unit is It is comprised so that the process other than the above defined based on may be performed.

  Since the rest of the configuration is the same as that of any one of the service systems according to the first to fifth embodiments, the description thereof is omitted.

  Such a configuration makes it possible to cope with, for example, a case where an electronic device is rented and the password information of the same electronic device is re-registered and reused every time the user changes. Specifically, for example, it is assumed that a certain user uses an electronic device by rental, and his password information is registered in association with the device identification information of the electronic device. Thereafter, the rental period ends, for example, when the user withdraws from the user, and the electronic device is temporarily returned to the owner (such as an administrator of the server device). Then, the cookie remaining in the electronic device is deleted. In the server device, the password information associated with the device identification information is discarded. Thereafter, the electronic device is rented to a new user. Therefore, when a new user accesses from the electronic device, the device identification information is that of the same device that has been used conventionally, so the comparison results match. However, since the cookie has been deleted, the determination result is inappropriate. The password is not sent because it is not set. Therefore, in the case of the comparison / determination result as described above, the processing execution unit of the server device prompts transmission of information to be registered to the server device so that the service can be provided to the electronic device. It is possible to receive a service using the electronic device which is a used product.

  <Process flow>

  FIG. 14 is a diagram illustrating an example of the flow of processing in the service system of the present embodiment.

  In processing execution step S1407 for prompting transmission of information to be registered to the server device so that the service can be provided to the electronic device, the service system compares the comparison result in the device identification information comparison step S1405 with the comparison result. When the determination result in the cookie determination step S1406 is an inappropriate determination result, a process for prompting transmission of information to be registered to the server device is executed so that the service can be provided to the electronic device. To do. If the comparison result in the device identification information comparison step does not match, or if the determination result in the cookie determination step is a determination result that is appropriate, in a predetermined process execution step S1408, the service system Processing other than the above determined based on the result in each step is executed.

  Since the remaining process flow is the same as the process flow in any one of the service systems according to the first to fifth embodiments, the description thereof will be omitted.

  FIG. 15 shows an example of predetermined processing execution contents according to the results in the device identification information comparison step, the cookie determination step, and the password information comparison step for reference. For example, in the case where the comparison result in the device information comparison step S1505 matches the comparison result, and in the case where the determination result in the cookie determination step S1506 is the determination result, the comparison result in the password information comparison step S1507 does not match. If YES, processing execution S1508 is performed to make it impossible to provide a service to the electronic device. In such a case, if the comparison result in the password information comparison step matches, the service is provided to the electronic device. The process execution S1509 for providing is performed. In addition, if the comparison result that the comparison result in the device information comparison step matches, and the determination result in the cookie determination step is a determination result that is inappropriate, the server device so that the service can be provided to the electronic device Processing execution S1510 for prompting transmission of information to be registered is performed. On the other hand, in the case where the comparison result in the device identification information comparison step is that the comparison result does not match, in the case where the determination result in the cookie determination step S1511 is a determination result that is inappropriate, the determination step whether or not there is password information If it is determined in S1512 that there is no password information, a process execution S1513 for registering the electronic device information in the server apparatus is performed, and it is determined that there is password information in the determination step of whether there is password information. If it is determined in the password information comparison step S1514, the device identification information included in the electronic device information including the password information with the same comparison result is replaced with the device identification for which the comparison result does not match. Process execution S1515 for registering and replacing information It is made.
