When executing the above program, the server device 50 realizes various functions by using the above hardware resources. The functional configuration realized by the server device 50 will be described. FIG. 3 is a block diagram showing an example of the functional configuration of the server device 50.

As shown in FIG. 3, the server device 50 has an acquisition unit 50A, a permission unit 50B, and a prohibition unit 50C as a functional configuration. Each functional configuration is realized by the CPU 51 reading and executing the registration permission program stored in the ROM 52 or the storage 54.

The acquisition unit 50A acquires the application information for which the registration application for the registration image 70 (see FIGS. 6 and 7) in the profile of the provided service has been made. Specifically, the user acquires the application information for which the user has applied for registration of the registration image 70 to the server device 50 via the device 20.

In addition, the acquisition unit 50A acquires the information of the image 70 for registration (see FIGS. 6 and 7) in the profile of the provided service. Specifically, the acquisition unit 50A acquires the information of the registration image 70 transmitted by the user to the server device 50 via the device 20.

In addition, the acquisition unit 50A acquires the information of the first face image 71 (hereinafter referred to as the proof face image 71 (see FIGS. 6 and 7)) used for the identification card. Specifically, the acquisition unit 50A acquires the information of the proof face image 71 transmitted by the user to the server device 50 via the device 20.

Further, the acquisition unit 50A acquires the information of one or more second face images 72 (see FIG. 8) from the cooperation service linked with the providing service. The linked service is a service linked with the provided service, and is a service in which a face image can be registered. Specifically, the linked service is a service that is linked in advance with the provided service. More specifically, the cooperation service is, for example, a social networking service (hereinafter referred to as SNS) that is linked in advance with the provided service and in which images (photographs) can be registered (posted). Therefore, the acquisition unit 50A acquires the information of the second face image 72 (hereinafter, referred to as the SNS face image 72) from the image of the photograph posted on the SNS, for example. The linked service is not limited to the service that has been linked in advance with the provided service. The linked service may be, for example, a service linked by the application of the registrant.

The permission unit 50B permits the registration of the registration image 70 in the profile when the similarity between the registration image 70 and the proof face image 71 is equal to or higher than the first threshold value. In other words, if the registration image 70 and the proof face image 71 are similar to each other according to a predetermined standard, the registration of the registration image 70 in the profile is permitted.

The degree of similarity can be calculated as a numerical value by using a known pattern matching method such as template matching.

In the present embodiment, as the first threshold value, when the similarity is equal to or higher than the value, it is considered that the person shown in the registration image 70 and the person shown in the proof face image 71 are the same person. A value obtained in advance is applied as a possible value. The first threshold value is not limited to this, and is not limited to this, for example, depending on the accuracy required for registration in the profile of the provided service, the purpose of the provided service, and the like, depending on the administrator of the server device 50 or the like.

When the similarity between the registration image 70 and the SNS face image 72 is equal to or higher than the third threshold value, the registration of the registration image 70 in the profile is permitted. In other words, if the registration image 70 and the proof face image 71 are similar to the SNS face image 72 according to a predetermined standard, the registration of the registration image 70 in the profile is permitted. The SNS face image 72 whose degree of similarity to the registration image 70 is determined and the SNS face image 72 whose degree of similarity to the proof face image 71 may be determined may be different.

In the present embodiment, as the second threshold, when the similarity between the proof face image 71 and the SNS face image 72 is equal to or higher than the value, the person in the proof face image 71 and the SNS face image 72 are captured. A value obtained in advance is applied as a value that can be regarded as the same person as the person in question. Further, in the present embodiment, as the third threshold value, when the similarity between the registration image 70 and the SNS face image 72 is equal to or higher than the value, the person in the registration image 70 and the SNS face image 72 are captured. A value obtained in advance is applied as a value that can be regarded as the same person as the person in question. The second threshold value and the third threshold value are not limited to these, and for example, the management of the server device 50 is performed according to the accuracy required for registration in the profile of the provided service, the use of the provided service, and the like. A second threshold value and a third threshold value may be set in advance by a person or the like via the input unit 56 or the like.

In the prohibition unit 50C, when the similarity between the registration image 70 and the proof face image 71 is less than the first threshold value, the similarity between the proof face image 71 and the SNS face image 72 is less than the second threshold value. Or, when the similarity between the registration image 70 and the SNS face image 72 is less than the third threshold value, the registration of the registration image 70 in the profile is prohibited.

(Action according to this embodiment)
Next, the operation of this embodiment will be described. 4 and 5 are flowcharts showing the flow of registration permission processing executed by the server device 50.

This process is performed by the CPU 51 reading the registration permission program from the ROM 52 or the storage 54 and executing it. This process is performed, for example, when a user applies for registration of the registration image 70.

As shown in FIG. 4, when the present process is started, the CPU 51 first acquires the information of the registration image 70 (see FIGS. 6 and 7) in the profile of the provided service (step S102). FIG. 6 shows a case where a face image obtained by capturing the user's face from the front (hereinafter, referred to as a front face image) is used as the registration image 70. FIG. 7 shows a case where a face image obtained by capturing the user's face from the side surface (hereinafter, referred to as a side face image) is used as the registration image 70.

Next, the CPU 51 acquires the information of the proof face image 71 (see FIGS. 6 and 7) used for the identification card (step S104). 6 and 7 show a case where the face image 71 of the front of the user shown on the identification card issued by a public institution such as a driver's license or a passport is used as the face image 71 for proof. .. The order of acquiring the information of the proof face image 71 and the information of the registration image 70 is not limited to the order of this processing, and the information of the proof face image 71 may be acquired first.

Next, the CPU 51 determines whether or not the similarity between the registration image 70 and the proof face image 71 is equal to or higher than the first threshold value (step S106).

When the CPU 51 determines in step S106 that the similarity between the registration image 70 and the proof face image 71 is equal to or higher than the first threshold value (step S106: YES), the registration image in the profile of the provided service Registration of 70 is permitted (step S108), and this process is terminated. In the example shown in FIG. 6, the case where the first threshold value is 0.7 and the degree of similarity between the registration image 70 and the proof face image 71 is 0.9 is shown. In the example shown in FIG. 6, registration of the registration image 70 is permitted.

On the other hand, when the CPU 51 determines in step S106 that the similarity between the registration image 70 and the proof face image 71 is less than the first threshold value (step S106: NO), step S110 (see FIG. 5). Move to. In the example shown in FIG. 7, the case where the first threshold value is 0.7 and the degree of similarity between the registration image 70 and the proof face image 71 is 0.5 is shown. In the example shown in FIG. 7, the process proceeds to step S110.

As shown in FIG. 5, in step S110, the CPU 51 acquires face image information from the posted image list 79 posted on the user's SNS, and creates the face image list 80. Here, as shown in FIG. 8, the posted image list 79 includes, for example, an image including a face image and an image not including a face image. Examples of the image that does not include the face image include a landscape image in which a landscape is captured, a food image in which a dish is captured, and a product image in which a product is captured. Then, the CPU 51 recognizes the face from the image of the posted image list 79, saves the image in which the face is recognized as a face image, and creates the face image list 80. The face image to be saved may be a face image cut out from an image including the face image. Further, a face image may be cut out from the moving image posted on the SNS.

Next, the CPU 51 acquires information on the degree of similarity (hereinafter, referred to as similarity A) of the face image (hereinafter, referred to as face image A) having the highest degree of similarity to the face image 71 for proof from the face image list 80 (step). S112). Specifically, as shown in FIG. 9, the CPU 51 calculates the similarity between each of the face images in the face image list 80 and the face image 71 for proof, and has the highest value among the similarity. Get similarity information.

Next, the CPU 51 determines whether or not the similarity A obtained with the information in step S112 is equal to or higher than the second threshold value (step S114).

When the CPU 51 determines in step S114 that the similarity A is equal to or higher than the second threshold value (step S114: YES), the CPU 51 proceeds to step S116. In the example shown in FIG. 9, the case where the second threshold value is 0.7 and the similarity A is 0.79 is shown. In the example shown in FIG. 9, the second threshold value has the same value as the first threshold value. Further, in the example shown in FIG. 9, the process proceeds to step S116.

On the other hand, when the CPU 51 determines in step S114 that the similarity A is less than the second threshold value (step S114: NO), the registration of the registration image 70 is prohibited (step S118). End the process.

In step S116, the CPU 51 acquires information on the degree of similarity (hereinafter, referred to as similarity B) of the face image (hereinafter, referred to as face image B) having the highest degree of similarity to the registration image 70 from the face image list 80. As shown in FIG. 10, the CPU 51 calculates the similarity between each of the face images in the face image list 80 and the registration image 70, and acquires information on the highest similarity among the similarity. To do.

Next, the CPU 51 determines whether or not the similarity B for which information has been acquired in step S116 is equal to or higher than the third threshold value (step S120).

When the CPU 51 determines in step S120 that the similarity B is equal to or higher than the third threshold value (step S120: YES), the CPU 51 permits the registration of the registration image 70 (step S122), and ends this process. To do. In the example shown in FIG. 10, the case where the third threshold value is 0.7 and the similarity A is 0.81 is shown. In the example shown in FIG. 10, the third threshold value is the same as the second threshold value and the first threshold value. Further, in the example shown in FIG. 10, registration of the registration image 70 is permitted.

On the other hand, when the CPU 51 determines in step S120 that the similarity B is less than the third threshold value (step S120: NO), the registration of the registration image 70 is prohibited (step S118). End the process. The registration image 70 whose registration is permitted in the registration permission process described above is finally registered in the profile of the provided service by the CPU 51.

As described above, in the present embodiment, the CPU 51 resembles the proof face image 71 and the SNS face image 72 when the similarity between the registration image 70 and the proof face image 71 is less than the first threshold value. When the degree is equal to or higher than the second threshold value and the degree of similarity between the registration image 70 and the SNS face image 72 is equal to or higher than the third threshold value, the registration of the registration image 70 in the profile is permitted. That is, in the present embodiment, even if the similarity between the registration image 70 and the proof face image 71 is less than the threshold value, the registration of the registration image 70 in the profile is permitted if certain conditions are satisfied.

Here, in the configuration in which the registration of the registration image 70 in the profile is permitted only when the similarity between the registration image 70 and the proof face image 71 is equal to or higher than the threshold value (hereinafter referred to as the first configuration), the proof is obtained. Only images whose similarity to the face image 71 is equal to or greater than the threshold value can be registered.

For example, when the face image of the identification card issued by a public institution such as a driver's license or a passport is used as the face image 71 for proof, the face image 71 for proof is the front face image. Therefore, as the registration image 70, only the front face image or the face image close to the front face image is permitted to be registered, and as the registration image 70, the face image obtained by capturing the face from the side (hereinafter, the side surface). (Face image) etc. cannot be used.

On the other hand, in the present embodiment, the similarity between the proof face image 71 and the SNS face image 72 is equal to or higher than the second threshold value, and the similarity between the registration image 70 and the SNS face image 72 is the third. When the value is equal to or greater than the threshold value, the registration of the registration image 70 in the profile is permitted, so that the degree of freedom of the image that can be registered is increased as compared with the first configuration described above. That is, according to the configuration of the present embodiment, as the registration image 70, for example, a side face image or the like can be used.

Further, in the present embodiment, when the similarity between the registration image 70 and the proof face image 71 is less than the first threshold value, the CPU 51 has the second degree of similarity between the proof face image 71 and the SNS face image 72. Registration of the registration image 70 in the profile is prohibited when it is less than two thresholds or the similarity between the registration image 70 and the SNS face image 72 is less than the third threshold.

Here, when the degree of similarity between the proof face image 71 and the SNS face image 72 is less than the second threshold value, or the degree of similarity between the registration image 70 and the SNS face image 72 is less than the third threshold value, In the configuration that allows the registration of the registration image 70 in the profile (hereinafter referred to as the second configuration), registration may be permitted even if the registration image 70 is not the image of the registrant himself / herself.

On the other hand, in the present embodiment, the similarity between the proof face image 71 and the SNS face image 72 is less than the second threshold value, or the similarity between the registration image 70 and the SNS face image 72 is the third. When the value is less than the threshold value, the registration of the registration image 70 in the profile is prohibited, so that the reliability that the registration image 70 is the image of the registrant himself is enhanced as compared with the second configuration described above.

(Modification example)
In the present embodiment, as described above, the face image information is acquired from the posted image list 79 posted on the SNS (step S110), and the information on the similarity A of the face image A is acquired (step S112). , It was determined whether or not the similarity A was equal to or higher than the second threshold value (step S114). In other words, in the present embodiment, the information regarding the face image A is acquired before the similarity determination by the face image A is performed (step S114). Specifically, before performing the similarity determination based on the face image A (step S114), after determining that the similarity between the registration image 70 and the proof face image 71 is less than the first threshold value (step). Information about the face image A was acquired in S106: NO). More specifically, the information about the face image A was acquired immediately before the similarity determination by the face image A was performed (step S114). The information about the face image A is not limited to the case where the information is acquired immediately before the similarity determination by the face image A is performed (step S114). For example, the degree of similarity between the registration image 70 and the proof face image 71 is the first threshold value. The configuration may be acquired in advance before determining whether or not the above is the case (step S106).

Further, in the present embodiment, the same values are used as the first threshold value, the second threshold value, and the third threshold value, but the present invention is not limited to this. For example, different values may be used for the first threshold value, the second threshold value, and the third threshold value. Specifically, the second threshold value may be a high value or a low value with respect to the first threshold value. Further, the third threshold value may be a high value or a low value with respect to the first threshold value and the second threshold value.

Further, considering that an image other than the face image (for example, an image of a landscape, an animal, etc.) is used as the registration image 70, the following processing may be performed. For example, after step S102 in FIG. 4 and before step S106, a face image determination as to whether or not the registration image 70 is a face image may be performed. That is, the face image determination may be performed between step S102 and step S104, or between step S104 and step S106.

In this case, for example, when the face image determination is performed between step S102 and step S104 and it is determined that the registration image 70 is a face image, the process proceeds to step S104. Further, when it is determined that the registration image 70 is a face image as a result of performing the face image determination between step S104 and step S106, the process proceeds to step S106.

If, as a result of the face image determination, it is determined that the registration image 70 is not a face image, the determination in step S106 is not performed, the process proceeds to step S118, and the registration of the registration image 70 is prohibited (step). S118), this process may be terminated. In this case, it is suppressed that an image other than the face image is registered as the registration image 70.

If, as a result of the face image determination, it is determined that the registration image 70 is not a face image, the registration image 70 does not perform the determination in step S106, proceeds to step S108, and transfers to the profile of the provided service. The registration of the registration image 70 may be permitted (step S108), and this process may be terminated. In this case, an image other than the face image can be registered as the registration image 70, but at least the registration of the face image of another person other than the registrant is suppressed. That is, it can be said that the process tries to allow the registration of an image other than the face image unless the face image of another person other than the registrant is registered.

In this way, by encouraging additional registration of the face image to the profile and additionally registering the face image to the profile, the image information registered in the profile is enriched.

As described above, in the present embodiment, apart from the registration image 70 whose similarity with the proof face image 71 is equal to or higher than the first threshold value, additional registration of the side face image to the profile is urged. Here, the registration image 70 having a similarity with the proof face image 71 of the first threshold value or more is considered to be a front face image or a face image close to the front face image. , Since the additional registration of the side face image to the profile is urged, the additional registration of the image of an angle different from the registration image 70 for which registration is permitted is urged to the profile.

<< Fifth Embodiment >>
Next, the fifth embodiment will be described. FIG. 15 is a flowchart showing a part of the flow of the registration permission process executed by the server device 50 according to the fifth embodiment. The same parts as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

As described above, in the first embodiment, the permission unit 50B has the similarity between the proof face image 71 and the SNS face image 72 of the different SNS face images 72 equal to or higher than the second threshold value, and the registration image. Even when the similarity between the 70 and the SNS face image 72 is equal to or higher than the third threshold value, the registration of the registration image 70 in the profile is permitted.

On the other hand, in the fifth embodiment, the permission unit 50B has a similarity with the proof face image 71 of the same SNS face image 72 or more and is similar to the registration image 70. When the degree is equal to or higher than the third threshold value, the registration of the registration image 70 in the profile is permitted.

The operation according to the fifth embodiment will be described below.

In the present embodiment, as shown in FIG. 4, when the CPU 51 determines in step S106 that the similarity between the registration image 70 and the proof face image 71 is less than the first threshold value (step S106). : NO), the process proceeds to step S510 (see FIG. 15) instead of step S110. For example, in the example shown in FIG. 7, the case where the first threshold value is 0.7 and the degree of similarity between the registration image 70 and the proof face image 71 is 0.5 is shown. In the example shown in FIG. 7, the process proceeds to step S510.

As shown in FIG. 15, in step S510, the CPU 51 acquires face image information from the posted image list 79 posted on the user's SNS, and creates the first face image list 81 and the second face image list 82. To do.

Here, as shown in FIG. 16, the posted image list 79 includes, for example, a face image and an image other than the face image. Examples of images other than the face image include a landscape image in which a landscape is captured, a food image in which a dish is captured, and a product image in which a product is captured. Then, the CPU 51 recognizes the face from the image of the posted image list 79, and creates the first face image list 81 and the second face image list 82 by using the face image for the image in which the face is recognized. The first face image list 81 and the second face image list 82 are lists having the same face image. The face image to be saved may be a face image cut out from an image including the face image. Further, a face image may be cut out from the moving image posted on the SNS.

Next, the CPU 51 acquires information on the degree of similarity (hereinafter, referred to as degree A) of the face image (hereinafter, referred to as face image A) having the highest degree of similarity to the face image 71 for proof from the first face image list 81. (Step S512). Specifically, as shown in FIG. 17, the CPU 51 calculates the similarity between each of the face images in the first face image list 81 and the face image 71 for proof, and is the most value among the similarity. Gets high similarity information.

When the CPU 51 determines in step S514 that the similarity A is equal to or higher than the second threshold value (step S514: YES), the CPU 51 proceeds to step S515. In the example shown in FIG. 17, the case where the second threshold value is 0.7 and the similarity A is 0.79 is shown. In the example shown in FIG. 17, the second threshold value has the same value as the first threshold value. Further, in the example shown in FIG. 17, the process proceeds to step S515.

On the other hand, when the CPU 51 determines in step S514 that the similarity A is less than the second threshold value (step S514: NO), the registration of the registration image 70 is prohibited (step S518). End the process.

In step S515, the face image A is stored in the first similarity list 91, and the face image A is deleted from the first face image list 81 (step S516). In the example shown in FIG. 17, the face image 4 as the face image A is stored in the first similarity list 91. Further, as shown in FIG. 18, the face image 4 is deleted from the first face image list 81.

Next, the CPU 51 acquires information on the degree of similarity (hereinafter referred to as similarity B) of the face image (hereinafter referred to as face image B) having the highest degree of similarity to the registration image 70 from the second face image list 82 (hereinafter referred to as “similarity B”). Step S516). Specifically, as shown in FIG. 19, the CPU 51 calculates the similarity between each of the face images in the second face image list 82 and the registration image 70, and the highest value among the similarity is calculated. Get high similarity information.

Next, the CPU 51 determines whether or not the similarity B for which information has been acquired in step S516 is equal to or higher than the third threshold value (step S520).

When the CPU 51 determines in step S520 that the similarity B is equal to or higher than the third threshold value (step S520: YES), the CPU 51 proceeds to step S521. In the example shown in FIG. 19, the case where the third threshold value is 0.7 and the similarity A is 0.81 is shown. In the example shown in FIG. 19, the third threshold value is the same as the second threshold value and the first threshold value. Further, in the example shown in FIG. 19, the process proceeds to step S521.

On the other hand, when the CPU 51 determines in step S520 that the similarity B is less than the third threshold value (step S520: NO), the registration of the registration image 70 is prohibited (step S518). End the process.

In step S521, the face image B is stored in the second similarity list 92, and the face image B is deleted from the second face image list 82 (step S521). In the example shown in FIG. 19, the face image 2 as the face image B is stored in the second similarity list 92. Further, as shown in FIG. 20, the face image 2 is deleted from the second face image list 82.

Next, the CPU 51 determines whether or not the same face image exists in the first similarity list 91 and the second similarity list 92 (step S523).

When the CPU 51 determines in step S523 that the same face image exists in the first similarity list 91 and the second similarity list 92 (step S523: YES), the CPU 51 permits the registration of the registration image 70, and this End the process.

On the other hand, when the CPU 51 determines in step S523 that the same face image does not exist in the first similarity list 91 and the second similarity list 92 (step S523: NO), the process returns to step S512.

In the example shown in FIGS. 17 and 18, after returning to step S512, the face image 2 having the second highest degree of similarity after the face image 4 is first, as shown in FIG. It is stored in the similarity list 91, and the face image 2 is deleted from the first face image list 81.

Further, through steps S520 and S522, as shown in FIG. 22, the face image 3 having the second highest degree of similarity after the face image 2 is stored in the second similarity list 92, and the face image 3 is the second face image. Removed from Listing 82.

Then, since the face image 2 which is the same face image exists in the first similarity list 91 shown in FIG. 21 and the second similarity list 92 shown in FIG. 22 (step S523: YES), the registration image. The registration of 70 is permitted, and this process is terminated.

As described above, in the present embodiment, for the same SNS face image 72, the similarity with the proof face image 71 is equal to or higher than the second threshold value, and the similarity with the registration image 70 is equal to or higher than the third threshold value. If, the registration of the registration image 70 in the profile is permitted.

Therefore, for different SNS face images 72, only when the similarity with the proof face image 71 is equal to or higher than the second threshold value and the similarity with the registration image 70 is equal to or higher than the third threshold value, the profile is entered. Compared with the configuration that allows the registration of the registration image 70, the reliability that the registration image 70 is the image of the registrant is enhanced.

<< 6th Embodiment >>

On the other hand, in the sixth embodiment, the permission unit 50B has a degree of similarity with the proof face image 71 of the different SNS face image 72 or more and a degree of similarity with the registration image 70. Is equal to or greater than the third threshold value, and if the additional condition is satisfied, the registration of the registration image 70 in the profile is permitted. Specifically, the additional condition is a condition that the similarity of the different SNS face images 72 is equal to or higher than the fourth threshold value.

The operation according to the sixth embodiment will be described below. The same parts as those according to the fifth embodiment are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

In the present embodiment, when the CPU 51 determines in step S523 that the same face image does not exist in the first similarity list 91 and the second similarity list 92 (step S523: NO), the process proceeds to step S602. .. In other words, for the same SNS face image 72, the condition that the similarity with the proof face image 71 is equal to or higher than the second threshold value and the similarity with the registration image 70 is equal to or higher than the third threshold value is satisfied. If not satisfied, the process proceeds to step S602. In other words, for different SNS face images 72, when the similarity with the proof face image 71 is equal to or higher than the second threshold value and the similarity with the registration image 70 is equal to or higher than the third threshold value, the step. Move to S602.

In step S602, it is determined whether or not the additional condition is satisfied. When it is determined in step S602 that the additional condition is satisfied (step S602: YES), the registration of the registration image 70 is permitted, and this process is terminated.

It is determined whether or not the similarity with the image 72 is equal to or higher than the fourth threshold value.

In the example shown in FIG. 24, the fourth threshold value is 0.7, and the degree of similarity between the face image 4 having the similarity with the proof face image 71 is equal to or higher than the second threshold value and the registration image 70. The case where the similarity with the face image 2 which is equal to or higher than the third threshold value is 0.75 is shown.
