  The present disclosure relates to control of an information processing terminal and a mobile terminal, and particularly relates to a technique for restricting use of a service provided by the information processing terminal.

  Mobile terminals such as smartphones that can use MFP services by communicating with MFPs (Multi-Functional Peripherals) have become widespread. An example of the MFP service is a print service. A user of the mobile terminal can print a photo stored in the mobile terminal by using the MFP print service. Recent portable terminals are equipped with electronic payment functions such as a PrePad function, a credit function, and an electronic money function, and a user of the portable terminal uses these electronic payment functions to use the print service of the MFP. Sometimes.

  When the portable terminal is stolen, the electronic payment function of the portable terminal may be abused. Therefore, a technique for determining whether or not the user of the mobile terminal is a regular user has been developed. With regard to such a technique, for example, Japanese Unexamined Patent Application Publication No. 2012-73724 (Patent Document 1) discloses a portable terminal that “performs user authentication by collating with a previously registered authentication image”.

Therefore, detailed description thereof will not be repeated. Each embodiment and each modified example described below may be selectively combined as appropriate.

<First Embodiment>
[Outline of Information Processing System 500]
With reference to FIG. 1, information processing system 500 according to the first embodiment will be described. FIG. 1 is a diagram illustrating an example of a device configuration of an information processing system 500.

  FIG. 1 shows an information processing terminal 100 as an MFP. Hereinafter, the information processing terminal 100 as an MFP will be described, but the information processing terminal 100 is not limited to the MFP. For example, the information processing terminal 100 may be an image forming apparatus having a FAX or other printing functions.

  Moreover, the portable terminal 300 as a smart phone is shown by FIG. Below, although the portable terminal 300 as a smart phone is demonstrated, the portable terminal 300 is not limited to a smart phone. For example, the mobile terminal 300 may be a tablet terminal, a notebook PC (Personal Computer), a digital camera, an electronic dictionary, a PDA (Personal Digital Assistant), or the like.

  The information processing system 500 includes, for example, an information processing terminal 100, a management server 200, and a mobile terminal 300. The information processing terminal 100, the management server 200, and the mobile terminal 300 are connected to each other on a network.

  The management server 200 is a web server that manages websites. The website includes, for example, an SNS (Social Networking Service) site. One of the services provided by the SNS site is a content management service such as an album service. The user can upload content such as image data and document data to the SNS site by using the content management service. The image data is, for example, photographic data or video. The document data is, for example, mail data or word data.

  The mobile terminal 300 can upload content to the SNS site of the management server 200. More specifically, the user logs in to the SNS site via the mobile terminal 300. Thereafter, the user selects content to be uploaded from the content stored in the mobile terminal 300. When the user performs upload, the mobile terminal 300 transmits the selected content to the management server 200. The management server 200 stores the content and the login information after associating the content received from the mobile terminal 300 with the login information input at the time of login.

  The content uploaded to the SNS site can be printed from the information processing terminal 100. More specifically, the information processing terminal 100 accepts input of login information to the SNS site of the management server 200 and logs in to the SNS site with the input login information. The information processing terminal 100 acquires the content uploaded to the login destination of the SNS site from the SNS site, and prints the acquired content.

  The content uploaded to the SNS site of the management server 200 is highly likely to be stored in the mobile terminal 300. Therefore, when the content uploaded to the login destination of the SNS site and the content stored in the mobile terminal 300 match or are similar, the information processing terminal 100 determines that the user of the mobile terminal 300 is a regular user. to decide.

  On the other hand, when the portable terminal 300 is stolen, the unauthorized user logs in to the SNS site using his / her login information. In this case, the content uploaded to the login destination of the SNS site is different from the content stored in the mobile terminal 300. Therefore, the information processing terminal 100 compares the content uploaded to the login destination of the SNS site with the content stored in the mobile terminal 300, and the comparison result indicates that these contents are dissimilar to each other. In this case, the use of the service of the information processing terminal 100 is prohibited. As a result, the information processing terminal 100 can prohibit the provision of services to unauthorized users of the mobile terminal 300.

  Preferably, the mobile terminal 300 has an electronic payment function. The electronic payment function includes a payment function such as a PrePid function, a credit function, and an electronic money function. Services of the information processing terminal 100 that are prohibited from use include services that use the electronic payment function of the mobile terminal 300. Thereby, the information processing terminal 100 can prevent the electronic payment function of the mobile terminal 300 from being used by unauthorized users.

[Prohibition of service]
Processing for prohibiting a service in the information processing system 500 will be described with reference to FIGS. FIG. 2 is a sequence diagram showing a data flow in information processing system 500. 3 and 4 are diagrams illustrating an example of screen transition of the information processing terminal 100. FIG. In the following, description will be made by taking photo data as an example of content as an example.

  2, the control device 101 (see FIG. 8) of the information processing terminal 100, the control device 201 (see FIG. 8) of the management server 200, and the control device 301 (see FIG. 8) of the portable terminal 300 execute programs. It is realized by doing.

  In step S210, the information processing terminal 100 displays a menu screen on the display 107 (see FIG. 3). It is assumed that the user of the information processing terminal 100 has selected a photo printing service from the menu screen.

  Preferably, when the photo printing service is selected, the display 107 of the information processing terminal 100 displays a selection screen for selecting a target SNS site from a plurality of types of SNS sites. The user selects an SNS site to which his / her photo data is uploaded from a plurality of types of SNS sites.

  When the SNS site is selected, the display 107 of the information processing terminal 100 displays a selection screen for selecting a payment method. Examples of the payment method include payment using cash, payment using the electronic payment function of the mobile terminal 300, and the like. Assume that the electronic payment function of the mobile terminal 300 is selected as the payment method.

  In step S212, based on selection of payment by the electronic payment function of the mobile terminal 300, the display 107 of the information processing terminal 100 displays a message for establishing communication with the mobile terminal 300 (see FIG. 3). ). The user touches the information processing terminal 100 with his / her mobile terminal 300. Thereby, communication between the information processing terminal 100 and the portable terminal 300 is established. Communication between the information processing terminal 100 and the portable terminal 300 is realized by, for example, short-range wireless communication means. As an example, the short-range wireless communication means includes NFC (Near field communication) (registered trademark), Bluetooth (registered trademark) communication, WiFi (registered trademark) communication, or the like.

  In step S214, the information processing terminal 100 accepts input of login information to the SNS site. For example, the information processing terminal 100 displays a login screen for inputting login information on the display 107 (see FIG. 3). The user inputs his / her account as login information on the login screen. The input login information is, for example, a user ID (Identification) or a password.

  In step S <b> 216, the information processing terminal 100 transmits the input login information to the management server 200. The management server 200 determines whether the user ID and password included in the received login information are registered. When the user ID and the password are registered, the management server 200 executes login to a login destination corresponding to the user ID. When the ID and the PW are not registered, the management server 200 transmits a message indicating that the login has failed to the information processing terminal 100. In the example of FIG. 2, it is assumed that login has been performed normally.

  In step S <b> 218, the user designates the posting period for the photo data to the information processing terminal 100. As an example, the information processing terminal 100 displays an input screen for a posting period of photo data on the display 107 (see FIG. 4). The input screen accepts designation of at least one of the start date and time and the end date and time of the posting period. Preferably, the posting period that can be specified is a past period.

  In step S222, the information processing terminal 100 transmits a request for acquiring photo data uploaded to the SNS site to the management server 200. When the management server 200 receives a request for obtaining photo data from the information processing terminal 100, the management server 200 uploads the photo data stored in the storage device 220 (see FIG. 8) during the period specified in step S214. Search the photograph data that has been saved.

  In step S224, the management server 200 transmits photo data that satisfies the search condition to the information processing terminal 100. Thereby, the information processing terminal 100 receives from the management server 200 the photo data uploaded to the SNS site during the period specified in step S214.

  In step S <b> 226, the information processing terminal 100 transmits a request for acquiring photo data to the mobile terminal 300. When the portable terminal 300 receives a request for acquiring photograph data from the information processing terminal 100, the portable terminal 300 generates the photograph data stored in the storage device 320 (see FIG. 8) during the period specified in step S214. Search the photograph data that has been saved.

  In step S <b> 228, the mobile terminal 300 transmits photo data that satisfies the search condition to the information processing terminal 100. Thereby, the information processing terminal 100 receives the photo data uploaded to the SNS site from the portable terminal 300 during the period designated in step S214.

  In step S230, the display 107 of the information processing terminal 100 displays a selection screen for selecting photo data to be printed from the photo data received in step S224 (see FIG. 4). The user selects the photo data to be printed from the photo data displayed on the selection screen.

  In step S232, the information processing terminal 100 compares the photo data acquired from the SNS site in step S224 with the photo data received from the mobile terminal 300 in step S228. Details of the photo data comparison process will be described later.

  In step S234, if the photo data acquired from the SNS site and the photo data received from the mobile terminal 300 are identical or similar to each other, the information processing terminal 100 determines that the user of the mobile terminal 300 is a valid user. . In this case, the information processing terminal 100 executes printing of the photo data selected in step S230. Alternatively, the information processing terminal 100 prints the photo data in the mobile terminal 300 that is similar or coincident with the photo data selected in step S230. Photo data uploaded to the SNS site may be compressed to reduce the data capacity. The information processing terminal 100 can print high-quality photo data by printing the photo data stored in the mobile terminal 300, not the photo data uploaded to the SNS site.

  When the photo data acquired from the SNS site and the photo data received from the mobile terminal 300 are dissimilar, the information processing terminal 100 determines that the user of the mobile terminal 300 is an unauthorized user. In this case, the information processing terminal 100 prohibits the use of the photo data printing service. As described above, the prohibited services of the information processing terminal 100 include a photo data printing service. The display 107 of the information processing terminal 100 displays a message indicating that the photo printing service is prohibited (see FIG. 4).

  Preferably, the information processing terminal 100 performs processing for acquiring photo data from the SNS site (steps S222 and S224), processing for receiving photo data from the mobile terminal 300 (steps S226 and S228), photo data acquired from the SNS site, A process of comparing the photograph data received from the portable terminal 300 (step S232) is executed in the background. Execution in the background refers to executing these processes without suggesting to the user that the processes in steps S222, S224, S226, S228, and S232 are being performed. That is, the content suggesting that these processes are being executed is not displayed on the display 107 of the information processing terminal 100. When the photo data acquired from the SNS site and the photo data received from the mobile terminal 300 are dissimilar, the information processing terminal 100 sends a notification indicating unauthorized use of the mobile terminal 300 to another information processing terminal (not shown). ). As described above, by executing each process of the information processing terminal 100 in the background, the information processing terminal 100 can send a notification indicating unauthorized use without being noticed by an unauthorized user.

  In the above description, an example in which the information processing terminal 100 receives photo data from the management server 200 and the portable terminal 300 based on the period specified in step S218 has been described. However, the period need not necessarily be specified. There is no. For example, the period may be determined in advance when the information processing terminal 100 is designed or manufactured. In this case, the information processing terminal 100 receives content uploaded to the SNS site from the management server 200 during a predetermined past certain period (hereinafter also referred to as “first period”). The information processing terminal 100 receives from the mobile terminal 300 photographic data generated during a predetermined past fixed period (hereinafter also referred to as “second period”). The first period and the second period may be the same or different.

[Photo data comparison process]
With reference to FIG. 5 and FIG. 6, the photographic data comparison process in step S232 of FIG. 2 will be described. FIG. 5 is a conceptual diagram showing comparison processing of photographic data. FIG. 6 is a conceptual diagram showing a photographic data comparison process in the modification.

  FIG. 5 shows photo data 230A and 230B and photo data 330A to 330C. The photo data 230 </ b> A and 230 </ b> B is photo data selected as a print target from photo data uploaded to the SNS site of the management server 200. The photo data 330 </ b> A to 330 </ b> C is photo data stored in the mobile terminal 300. Hereinafter, the photo data 230A and 230B are collectively referred to as photo data 230. Photo data 330A to 330C are also collectively referred to as photo data 330.

  The information processing terminal 100 calculates the similarity between the photo data 230 and the photo data 330. When the similarity satisfies the condition indicating that the photograph data 230 and the photograph data 330 are dissimilar (hereinafter, also referred to as “dissimilar condition”), the information processing terminal 100 is a user of the portable terminal 300. It is determined that the user is an unauthorized user, and use of the service of the information processing terminal 100 is prohibited. Below, the calculation method of similarity and dissimilar conditions are demonstrated in order.

(Similarity calculation method)
In one aspect, the information processing terminal 100 calculates the similarity between the photo data 230 and the photo data 330 by comparing the Exif information included in the photo data 230 with the Exif information in the photo data 330. Exif information is information relating to the shooting conditions of the photographic data. As an example, the Exif information includes the shooting date and time, the manufacturer name (manufacturer, etc.) of the shooting device, the model name of the shooting device (model name of the smartphone, etc.), the resolution of the photo data, the shooting direction, the shutter speed, and the aperture (so-called F value). , Sensitivity, presence / absence of flash, focal length, position information at the time of shooting (for example, latitude, longitude, altitude), and the like. When the photo data 230 includes Exif information and the photo data 330 includes Exif information, the information processing terminal 100 compares the Exif information of the photo data 230 with the Exif information of the photo data 330. Thus, it is determined whether or not the photo data 230 and the photo data 330 are dissimilar.

  In the example of FIG. 5, the information processing terminal 100 calculates the degree of similarity between the Exif information of the photo data 230A and the Exif information of the photo data 330A to 330C, and the Exif information of the photo data 230B and the photo data 330A to 330C. Similarity with each of the Exif information is calculated. Thereby, the information processing terminal 100 obtains the same degree of similarity as the number of combinations of each of the photo data 230A and 230B and each of the photo data 330A to 330C. Preferably, the degree of similarity increases as the contents of Exif information match.

  In another aspect, the information processing terminal 100 calculates the similarity between the photo data 230 and the photo data 330 by comparing the image information of the photo data 230 and the image information with the photo data 330. The image information includes, for example, pixel values and feature amounts extracted from photo data. As an example, the similarity corresponds to a correlation value between the image information of the photo data 230 and the image information of the photo data 330. As a correlation value calculation method, for example, SSD (Sum of Squared Difference), SAD (Sum of Absolute Difference), NCC (Normalized Cross-Correlation), or ZNCC (Zero-mean Normalized Cross-Correlation) is adopted.

  In the example of FIG. 5, the information processing terminal 100 calculates the similarity between the image information of the photographic data 230A and the image information of the photographic data 330A to 330C, and the image information of the photographic data 230B and the photographic data 330A to 330C. The similarity with each of the image information is calculated. Thereby, the information processing terminal 100 obtains the same degree of similarity as the number of combinations of each of the photo data 230A and 230B and each of the photo data 330A to 330C.

(Dissimilar condition)
Below, dissimilar conditions are demonstrated. When the similarity calculated by the above method satisfies the condition indicating that the photograph data 230 and the photograph data 330 are dissimilar to each other (that is, the dissimilar condition), the information processing terminal 100 And the photo data 330 are determined to be dissimilar. In other words, when the similarity calculated by the above method does not satisfy the dissimilarity condition, it is determined that the photo data 230 and the photo data 330 are similar.

  In one aspect, the information processing terminal 100 determines that the dissimilarity condition is satisfied when at least a part of the photograph data 230A and 230B acquired from the SNS site is dissimilar to the photograph data 330A to 330C. In other words, the information processing terminal 100 determines that the dissimilarity condition is not satisfied when all of the photo data acquired from the SNS is stored in the mobile terminal 300.

  For example, the information processing terminal 100 determines that any of the similarities between the photo data 230A and the photo data 330A to 330C exceeds a predetermined threshold (for example, 90%), and the photo data 230B and the photo data 330A to 330C. If any of the similarity degrees exceeds a predetermined threshold (for example, 90%), it is determined that the dissimilarity condition is not satisfied. In the example of FIG. 5, it is determined that the photograph data 230A and the photograph data 330A are similar, and it is determined that the photograph data 230B and the photograph data 330C are similar. As described above, since all the photo data 230A and 230B acquired from the SNS site are stored in the mobile terminal 300, the dissimilar conditions are not satisfied, and the information processing terminal 100 is that the user of the mobile terminal 300 is a valid user. Judge.

  In another aspect, the information processing terminal 100 determines that the dissimilarity condition is satisfied when all of the photo data 230A and 230B acquired from the SNS site are dissimilar to the photo data 330A to 330C. In other words, the information processing terminal 100 determines that the dissimilarity condition is not satisfied when at least one of the photo data 230A and 230B acquired from the SNS is stored in the mobile terminal 300.

  For example, the information processing terminal 100 determines that the similarity between the photo data 230A and the photo data 330A to 330C exceeds a predetermined threshold (for example, 95%), or the photo data 230B and the photo data 330A. When any of the similarities to ˜330C exceeds a predetermined threshold (for example, 95%), it is determined that the dissimilarity condition is not satisfied. In the example of FIG. 6, it is determined that the photograph data 230A and the photograph data 330A are similar. Thus, since the photo data 230A, which is one of the photo data acquired from the SNS site, is stored in the mobile terminal 300, the dissimilarity condition is not satisfied, and the information processing terminal 100 is authorized by the user of the mobile terminal 300. Determine user.

  Note that the photo data 230 and the photo data 330 do not need to be completely matched. The photo data 230 uploaded to the SNS site of the management server 200 may be compressed in order to reduce the data capacity. Therefore, the photo data 230 and the photo data 330 may not completely match.
