FIG. 1 is a diagram showing a system 100 according to a first embodiment of the present invention. The system 100 is represented by a server 10, a network 60 that connects the server 10 and the base station 40 with a wired line, a first base station 40 a to a third base station 40 c represented by the base station 40, and a mobile terminal 50. The first mobile terminal 50a to the third mobile terminal 50c and the PC terminal 70 are included. The mobile terminal 50 includes, for example, a feature phone, a smartphone, a tablet terminal, and the like.

  In this system 100, a predetermined service is provided from the server 10 to the PC terminal 70 via the network 60 or to the mobile terminal 50 via the network 60 and the base station 40. This service includes, for example, a game service provided on SNS (Social Networking Service) and a service that uses a game application downloaded to the terminal from an application providing platform. The application providing platform may be integrated with the server 10 or provided separately.

  The system 100 also has a function of inviting unregistered users (invited users) from registered users (invited users) to the services in order to increase the number of users registered in these services. This invitation is performed by sending an invitation message including content information for invitation described later from the invitation source user to the invitation destination user by e-mail or the like. When the invitee user registers in the service and registers the content information for invitation, a privilege that can be used in the service can be given to the inviter user and / or the invitee user.

  In the following description, the invitation image is used as the invitation content information. However, not only the image but also information including binary data such as audio and moving images can have the same effect. Needless to say. In the case of image content, it is considered difficult to generate a completely identical image by means other than copying, so that security can be improved.

  In FIG. 1, only three base stations 40 and mobile terminals 50 are shown for convenience of illustration. However, the number of base stations 40 and mobile terminals 50 may be more than that. The same applies to the PC terminal 70. In addition, the first mobile terminal 50 a to the third mobile terminal 50 c are illustrated as being connected to different base stations 40, but not limited to this, a plurality of mobile terminals 50 are connected to one base station 40. Needless to say, the present invention is applicable. The base station 40 may be an access point such as a wireless LAN. Hereinafter, the mobile terminal 50 and the PC terminal 70 are collectively referred to as user terminals.

Here, for convenience of explanation, the configuration of the mobile terminal 50 will be described, but the PC terminal 70 has the same configuration. The mobile terminal 50 includes a terminal communication unit 51, a terminal control unit 52, a user interface 53, and a terminal memory 54.

  The terminal communication unit 51 receives application programs downloaded from the server 10 and various information transmitted from the server 10. Further, various information is transmitted to the server 10 in accordance with the user input operation received by the user interface 53.

  The terminal control unit 52 receives a user instruction from the user interface 53 and performs application installation control, application execution control, and the like while accessing the terminal memory 54.

  The user interface 53 includes a screen interface for displaying various screens such as a message to the user and a content viewing screen, a speaker for outputting sound and the like, and an input interface for receiving input from the user such as a keyboard and a touch panel. The user interface 53 accepts a selection operation from a user or an input operation of various information and transmits the received information to the terminal control unit 52.

  The terminal memory 54 is used to store an application program downloaded from the application providing platform when installing an application. Various information from the server 10 received by the terminal communication unit 51, user identification information (user ID) used in applications, and the like are stored.

  For example, when the terminal control unit 52 starts a game application in response to an operation of the user interface 53 by the user, the game proceeds while the terminal communication unit 51 communicates with the server 10 via the network 60. When receiving an instruction from the user via the user interface 53 during execution of the application, the terminal control unit 52 transmits an invitation request for inviting the invited user to the service via the terminal communication unit 51 to the server 10. An invitation image to be described later can be acquired.

  The terminal control unit 52 can create an invitation message including the acquired invitation image and send it to the invitee user's terminal according to the user's instruction. Here, the user terminal of the invitation destination accesses the server 10 using the link described in the invitation message and downloads the application. Further, by sending the invitation image attached to the invitation message to the server 10, the registration process for the service related to the application is easily executed. In this manner, the invitee user terminal can easily perform the registration process without requiring complicated operations such as inputting a plurality of alphanumeric characters that have been used in the past, thereby improving the service registration willingness. be able to.

  FIG. 3 is a diagram illustrating a configuration example of the server 10 of FIG. The server 10 includes a server communication unit 11, a user information management unit 12, a game processing unit 13, a screen display control unit 14, an invitation processing unit 15, a user registration unit 16, a privilege granting unit 17, and a server. And a memory 18. The server memory 18 stores a user information table 181 and an invitation information table 182.

  The server communication unit 11 receives a signal from the user terminal, performs a predetermined demodulation process, and performs a user information management unit 12, a game processing unit 13, a screen display control unit 14, an invitation processing unit 15, or a user registration unit. The demodulated signal is sent to 16 or the like.

  Also, the server communication unit 11 receives predetermined instructions from the game processing unit 13, the screen display control unit 14, the invitation processing unit 15, the privilege granting unit 17, and the like, modulates predetermined data, and transmits the data to the user terminal. To do. The predetermined data includes, for example, an image related to a game, an image for invitation, information related to a privilege, and the like.

  The modulation / demodulation processing in the server communication unit 11 may use a conventionally used modulation / demodulation technique, and it will be understood by those skilled in the art that the present invention can be applied even in such a mode. is there.

  The user information management unit 12 manages information related to users registered in the system 100 in the user information table 181 of the server memory 18. For example, as shown in FIG. 4, the user information table 181 includes a user ID, a user name, and a password. These pieces of user information are referred to in the game processing unit 13 or the like.

  The game processing unit 13 receives a game start request that can be executed on the system 100 from the user terminal via the server communication unit 11, starts the game, and manages the progress of the game. In addition, the game processing unit 13 accesses user information stored in the server memory 18 and executes predetermined processing when the game progresses.

  The screen display control unit 14 performs control to display a predetermined image on the screen of the user terminal according to the progress of the game or according to the instruction of the game processing unit 13. When the game application is activated for the first time, a user registration screen is displayed on the screen of the user terminal.

  The invitation processing unit 15 receives an invitation request transmitted from the terminal of the invitation source user of the service via the server communication unit 11, issues an invitation image for the service, and transmits the invitation image to the terminal of the invitation source user. To do. For example, as shown in FIG. 5, the issued invitation image is stored in the invitation information table 182 in the server memory 18 together with the identification information (invitation source user ID) of the invitation source user. The invitation image can include an outline of the service and advertisement information in addition to information indicating the service.

  “Including service information, service summary, advertisement information, etc.” means that service names and advertisements related to invited apps and benefits, or barcode information such as UUID can be recognized as characters or images. It may be superimposed on the invitation image in such a manner, or may be superimposed electronically using an electronic watermark technique or the like. By such an aspect, even if a binary change such as resizing the invitation image at the time of mail transmission is made, it is possible to collate. In addition, by including barcode information such as a barcode and a two-dimensional code in the invitation image, an appropriate registration process can be easily realized by image collation. In addition, when an advertisement is included in the invitation image, the user's visibility when searching for the invitation image stored in the user terminal is improved, and the user on the advertisement is compared with the invitation code based on the conventional inorganic text data. Can be invited as an attractive service. According to such an aspect, since a login attempt by a third party of a registration ID as a character string in the past, for example, a brute force attack that detects a registration ID in a brute force becomes difficult, safety is improved. Since it is extremely difficult to perform a brute force attack on information superimposed on an image, the security level can be increased. The invitation image may be a common image for the entire service, or a different image may be issued for each invitation source user.

  For example, when the application is started for the first time, the user registration unit 16 displays a user registration screen on the screen of the user terminal, and performs user registration processing based on the input user information.

  The privilege granting unit 17 compares the invitation image uploaded from the terminal of the invitation destination user with the invitation image stored in the invitation information table 182 when the invitation destination user is registered in the user registration unit 16. Based on the comparison result, a privilege is given to the inviting user and / or the inviting user. The benefits include, for example, presents such as in-game currency and items, points that can be used in common in other services provided by the system 100, and the like. In order to further enhance security, in addition to uploading and verifying invitation images, processing for identity verification, such as user ID verification and password verification, registration in other services provided by the same server 10 Matching with the situation may be made.

  Next, the operation of the system according to the first embodiment will be described with reference to FIGS. 6 and 7. FIG. 6 is a sequence diagram illustrating a processing procedure of the system according to the first embodiment. Here, a case where the user (invitation source user) of the first mobile terminal 50a invites the user (invitation destination user) of the second mobile terminal 50b to the game service will be described as an example.

  During the execution of the game service, the first mobile terminal 50a transmits an invitation request including the user ID to the server 10 by the operation of the inviting user (step S6a). Upon receiving this invitation request, the invitation processing unit 15 of the server 10 issues an invitation source user's invitation image and sets it in the invitation information table 182 together with the invitation source user ID, and the invitation image is sent to the first mobile terminal 50a. Transmit (step S6b).

  The invitation source user transmits an invitation message including an invitation image by e-mail, SNS or the like from the first mobile terminal 50a to the second mobile terminal 50b in order to have the invitee user install the application of the game service ( Step S6c). Instead of transmitting, the second mobile terminal 50b may acquire an invitation image using an electronic recording medium or a cloud storage on a network. Upon receiving this invitation message, the invited user installs the application of the game service on the second mobile terminal 50b (step S6d). For example, a download request is transmitted from an application download screen of the application providing platform, and an application program is received.

  The invitee user activates the installed application on the second mobile terminal 50b (step S6e), inputs user information on the user registration screen, and transmits it to the server 10 (step S6f).

  FIG. 7A shows an example of the user registration screen. The user registration screen 700 includes a user name input field 701, a password input field 702, and a registration button 703. In the user name input field 701 and the password input field 702, any combination of numbers and characters can be set. When the registration button 703 is pressed by the invitee user, the second mobile terminal 50b transmits the user name and password input in the user name input field 701 and the password input field 702 to the server 10.

  The user registration unit 16 of the server 10 receives the user name and password transmitted from the second mobile terminal 50b, and performs user registration processing (step S6g). For example, the user registration unit 16 issues a new user ID, and stores the user name and password in the user information table 181 in association with the issued user ID.

  When the user registration process is completed, an invitation image registration screen is displayed on the second mobile terminal 50b (step S6h). FIG. 7B shows an example of the invitation image registration screen. The invitation image registration screen 710 includes an upload button 711, an invitation image display field 712, and a registration button 713. When the upload button 711 is pressed, an image selection screen 720 indicated by a broken line is displayed so as to be superimposed on the invitation image registration screen 710, and an invitation image can be selected. The selected invitation image (here, image 1) is displayed in the invitation image display field 712. When the registration button 713 is pressed by the invitee user, the second mobile terminal 50 b transmits the selected invitation image to the server 10. The user registration screen 700 and the invitation image registration screen 710 are configured as one screen, and the user information and the invitation image are input simultaneously, and both the user information and the invitation image are transmitted to the server 10. May be.

  The privilege granting unit 17 of the server 10 compares the invitation image uploaded from the second mobile terminal 50b with the invitation image set in the invitation information table 182 (step S6i). By this comparison, when an invitation image that matches the uploaded invitation image can be found from the invitation information table 182, the invitation source user is specified, and the privilege granting unit 17 and the invitation source user specified by the comparison result A privilege is given to an invitation destination user (step S6j).

Here, the method for comparing the invitation images in step S6i will be described according to the following example.
Example 1
In the first embodiment, the privilege granting unit 17 compares binary data between the invitation image uploaded from the second mobile terminal 50 b of the invitation destination user and the invitation image set by the invitation processing unit 15. By comparing the binary data, it is possible to accurately determine whether or not the image data is the same, and the processed invitation image can be distinguished.

(Example 2)
In the second embodiment, the privilege granting unit 17 calculates the hash value calculated from the invitation image uploaded from the second mobile terminal 50 b of the invitation destination user and the hash value calculated from the invitation image set by the invitation processing unit 15. And compare. Since it is difficult to forge images having the same hash value, security can be improved.

(Example 3)
In the third embodiment, the invitation image includes a two-dimensional code such as a barcode or QR code (registered trademark) obtained by converting predetermined information, and the privilege granting unit 17 is uploaded from the second mobile terminal 50b of the invited user. The information read from the invitation image is compared with the information read from the invitation image set by the invitation processing unit 15. By including predetermined information in an identification code such as a barcode or a two-dimensional code, image comparison can be easily performed. Furthermore, by including the invitation source user ID in a barcode, two-dimensional code, etc., the invitation source user ID can be easily specified by image comparison, and the invitation source user ID can be omitted in the invitation information table 182. .

As described above, according to the first embodiment, the registration procedure can be performed simply by selecting and uploading the invitation image, so that manual input of the invitation ID can be omitted, and simple registration is possible.
Further, when it is desired to prevent leakage of the invitation ID such as pre-registration, it is difficult to generate the same image by using image data instead of the invitation ID, and security can be improved.
In addition, since the invitation image can include, for example, information representing the service, advertisement information, and the like, the invitation image is invited as a service that attracts the user for advertisement compared to the conventional invitation ID based on inorganic text data. Is possible.

(Second Embodiment)
In the first embodiment, the invitation image is issued on the server side, but in the second embodiment, the image held in the terminal of the invitation source user is used as the invitation image. Since the configuration of the system and apparatus is the same as that of the first embodiment, the description will be made with reference to FIGS. 1 to 3, and the description overlapping with that of the first embodiment will be omitted.

  The operation of the system according to the second embodiment will be described. FIG. 8 is a sequence diagram illustrating a processing procedure of the system according to the second embodiment. As in the first embodiment, a case where the user (invitation source user) of the first mobile terminal 50a invites the user (invitation destination user) of the second mobile terminal 50b to the game service will be described as an example.

  During the execution of the game service, the first mobile terminal 50a transmits an invitation request including the user ID and the invitation image to the server 10 by the operation of the invitation source user (step S8a). As the invitation image, an image held in the first mobile terminal 50a can be arbitrarily selected. Upon receiving this invitation request, the invitation processing unit 15 of the server 10 sets the invitation image selected by the invitation source user together with the invitation source user ID in the invitation information table 182 (step S8b).

  The invitation source user transmits an invitation message including an invitation image by e-mail, SNS, or the like from the first mobile terminal 50a to the second mobile terminal 50b in order for the invitation destination user to install the application of the game service. (Step S8c). In response to the invitation message, the invitee user installs the application of the game service on the second mobile terminal 50b (step S8d). For example, a download request is transmitted from an application download screen of the application providing platform, and an application program is received.

  The invitee user activates the application installed in the second mobile terminal 50b (step S8e), inputs user information on the user registration screen as shown in FIG. 7A and transmits it to the server 10 (step S8f). The user registration unit 16 of the server 10 receives the user name and password transmitted from the second mobile terminal 50b, and performs user registration processing (step S8g).

  When the user registration process is completed, an invitation image registration screen as shown in FIG. 7B is displayed on the second mobile terminal 50b. When the invitation user selects an invitation image on the invitation image registration screen, the second mobile terminal 50b uploads the selected invitation image to the server 10 (step S8h).

  The privilege granting unit 17 of the server 10 compares the invitation image uploaded from the second mobile terminal 50b with the invitation image set in the invitation information table 182 (step S8i). If an invitation image that matches the uploaded invitation image can be found from the invitation information table 182 by this comparison, the invitation source user is specified, and the privilege granting unit 17 performs the comparison result after the user registration of the invitee user. A privilege is given to the invitation source user and the invitation destination user specified by (step S8j).

  As described above, according to the second embodiment, the same effect as that of the first embodiment can be obtained, and an invitation destination user can be used as a service by using an image held by the invitation source user as an invitation image. It becomes easier to invite.
