Description

Game content-based account authentication method and system {METHOD AND SYSTEM FOR AUTHENTICATING ACCOUNT BASED ON GAME CONTENT}

The following description relates to a method and system for authenticating an account based on game content.

There are various techniques for authenticating a user accessing a game as a valid user. The most common example for user account authentication is a method of authenticating a user by receiving a user's unique identification information and password and comparing the identification information with a pre-registered password. As another example, authentication through e-mail exists, but e-mail authentication is inconvenient for users who are reluctant to set up e-mail, and during actual e-mail authentication, it is inconvenient to get out of the game and check the e-mail authentication value. In addition, the biometric authentication method has a problem that a terminal supporting biometric recognition is required, and OTP (One Time Password) authentication requires a dedicated app to be installed, and OTP application to the game platform must be supported. There is a hassle to check the value.

In the embodiment of FIG. 3 , the content platform 310 , the user terminal 320 , the content provider terminal 330 and the content providing server 340 are shown. Here, each of the content platform 310, the user terminal 320, the content provider terminal 330, and the content providing server 340 may be implemented by the computer device 200 described above. In this case, the user terminal 320 may refer to a terminal device used by a user using content to access the content platform 310 and/or the content providing server 340 . Also, the content provider terminal 330 may refer to a terminal device used by a content provider to access the content platform 310 and/or the content providing server 340 .

In addition, although the embodiment of FIG. 3 shows one user terminal 320, one content provider terminal 330, and one content providing server 340, each may include two or more. For example, two or more content providers may each register one or more content on the content platform 310, and a plurality of content providing servers for the registered content may be operated. In this case, one content provider may register two or more content and operate two or more content providing servers. In addition, a plurality of users may receive content by accessing a content providing server providing desired content among a plurality of content providing servers via the content platform 310 .

At this time, the content provider terminal 330 uploads the computer program (for example, in the case of game content, a game app) for the content provider's content to the content platform 310, while uploading the content provider's content to the content platform ( 310) can be registered.

The user terminal 320 may download the above-described computer program through the content platform 310 and install and run it in the user terminal 320 . In this case, the user terminal 320 may receive content while communicating with the content providing server 340 under the control of the driven computer program.

At this time, the content platform 310 may include an account authentication system 311 to authenticate the account of a user accessing through the user terminal 320 . The account authentication system 311 may use various authentication methods such as password authentication and e-mail authentication. For example, the account authentication system 311 receives the user's account and password, firstly authenticates the user's account, and then secondarily authenticates the user's account using the account authentication method according to embodiments of the present invention. can As such, the account authentication system 311 may authenticate the user's account using two or more of various authentication methods, and at this time, an account authentication method according to embodiments of the present invention may be used as one of the various authentication methods. there is.

The account authentication method according to the embodiments of the present invention may be performed using information that is determined to be already known by the user in relation to the progress of the user's game content. For example, in the case of a game in which an area is given to each user within the game, authentication for the user's account may be performed using an image of the user's own area that the user already knows. This account authentication method will be described in more detail later with reference to FIG. 4 .

4 is a flowchart illustrating an example of an account authentication method according to an embodiment of the present invention. The account authentication method according to this embodiment may be performed by the computer device 200 implementing the content platform 310 or the account authentication system 311 described above with reference to FIG. 3 . In this case, the processor 220 of the computer device 200 may be implemented to execute a control instruction according to an operating system code included in the memory 210 or a code of at least one computer program. Here, the processor 220 controls the computer device 200 so that the computer device 200 performs steps 410 to 450 included in the method of FIG. 4 according to control commands provided by codes stored in the computer device 200. can control.

In step 410, the computer device 200 may collect and store information related to the progress of the user's game content in a database. Here, the information related to the progress of the game content includes (1) information about game objects stored in association with the user's identifier, (2) information about game events stored in association with the user's identifier, (3) information about the user and Information on other users with whom personal relationships have been established within game content, (4) information about other users with whom personal relationships have been established on social networks associated with users and game content, (5) users registered on the same content platform as game content It may include at least one of information related to the progress of other game contents, (6) information on text input by the user within the game contents, and (7) information on a device used by the user to progress the game contents.

In this case, (1) the information on the game object stored in association with the user's identifier may include an image including the game object. For example, in the case of a game in which an individual user is given a region within the game, an image of the user's own region that the user already knows may be collected as information related to the progress of the user's game content. As another example, an image of a character recently fostered by the user or an image of a character of a specific level possessed by the user may be collected as information related to the progress of the user's game content. As another example, in the case of a sports game, an image of an opposing team in which the user most recently played may be collected as information related to the progress of the user's game content. As such, various information about game objects stored in association with the user's identifier may be collected as information related to the progress of game content.

In addition, (2) information on game events stored in association with the user's identifier is, for example, the name set by the user for a specific character of the user, information related to the user's access time, the dungeon used by the user, or Information about the acquired item may be included. As another example, in the case of a sports game, the team name of the opponent team in which the user most recently played may be collected as information related to the progress of game content.

Also, (3) information on other users with whom a user has a personal relationship established within the game content may include, for example, information on other users belonging to a federation or guild of a user existing in the game. For example, an identifier identifying a corresponding other user in a game may be collected as information related to the progress of game content.

In addition, (4) information about other users whose personal relationships are established on social networks associated with the user and the game content is, for example, information on the personal relationship of the user can be collected in the content platform 310 in association with the game content. Information on a user's friends on a specific social network may be collected as information related to the progress of game content.

In addition, (5) information related to the progress of other game contents of a user registered on the same content platform as the game content may mean that information related to the progress of the game content may be collected from a plurality of game contents used by the user. . As an example, it is assumed that a user plays game content a and game content b among a plurality of game contents registered on the content platform 310 . At this time, when the user requests account recognition in relation to game content a, information related to the progress of game content b as well as game content a may be utilized. Information related to the progress of the game content may be collected from the game content of .

Also, (6) information on text input by the user within the game content may include, for example, information on a chatting message input by the user on the game.

Also, (7) information on a device used by the user to play game content may include a brand name or model name of the corresponding device.

Information related to the progress of the game content may already be distributed and stored in various databases, and may be newly generated as the user proceeds with the game content. The computer device 200 may collect and store information related to the progress of game contents distributed and stored in these various databases into one database for problem generation, and as new information is generated, the database for problem generation information can be updated.

In step 420, the computer device 200 may extract any information stored in the database in response to the user's account authentication request. At this time, the authentication request may be transferred from the user's terminal (eg, the user terminal 320) to the computer device 200 through the network 170. Meanwhile, problems to be presented to the user may vary depending on what type of information is extracted. As an example, (6) when information about the text entered by the user within the game content is extracted, the problem of selecting the content that the user most recently entered in the chatting window may be presented, and (2) the user's identifier and When information on game events stored in association with each other is extracted, a problem of selecting a correct answer for the corresponding event may be presented.

In step 430, the computer device 200 may create a problem having any extracted information as a correct answer. In one embodiment, the computer device 200 may generate at least one incorrect answer having a different value of the same type as the extracted arbitrary information, and a multiple-choice type having the extracted arbitrary information as the correct answer and having at least one incorrect answer. can create problems. In this case, as the number of incorrect answers increases, security may be improved. In another embodiment, the computer device 200 may extract a plurality of pieces of information of the same type stored in the database in step 420 . In this case, the computer device 200 generates one correct answer having a different value of the same type as the plurality of information extracted in step 430, and generates one correct answer having each of the extracted plurality of information as an incorrect answer. You can create multiple choice questions with In other words, multiple-choice questions can be created that look for information that is not collected about the user. As another embodiment, the computer device 200 may generate i (i is a natural number) wrong answers having different values of the same type as the extracted random information, including the extracted random information and i wrong answers. It is possible to create a multiple-choice problem with j (j is a natural number less than or equal to i) number of options randomly selected from among i+1 options. As another embodiment, a subjective question that requires an answer to an arbitrary extracted information as a correct answer may be created.

In step 440, the computer device 200 may provide the generated problem to the user. At this time, the computer device 200 may transmit the problem generated through the network 170 to the user's terminal (eg, the user terminal 310). In the user's terminal, the generated problem may be output to the user, and the user may select or input an answer to the problem.

In this case, when i or less of the i+1 options are randomly selected to generate a multiple-choice question, a correct answer according to information extracted from among the selected options may not be included. Accordingly, the computer device 200 may further provide a function for the user to re-select the j number of answers for the multiple-choice question when there is no correct answer among the j number of answers. Therefore, security can be improved because the probability of a randomly selected answer is reduced.

In step 450, the computer device 200 may authenticate the account of the user when the correct answer to the problem provided by the user is input. For example, when a user selects or inputs an answer to a presented problem, the selected or inputted answer may be transmitted to the computer device 200 through the network 170 . In this case, the computer device 200 may determine whether the delivered answer is correct, and if the delivered answer is correct, the user's account may be authenticated.

Meanwhile, according to the embodiment, the account authentication method according to steps 410 to 450 may be used as an n (n is a natural number) order authentication method for user account authentication. For example, the account authentication method according to the embodiment may further include a step (not shown) of first authenticating the user's account between steps 410 and 420 . In this case, authenticating the account of the user in steps 420 to 450 may be secondarily authenticating the account of the firstly authenticated user. A method of first authenticating a user's account may be one of various well-known account authentication methods.

In addition, since there is a probability that a randomly selected answer will be the correct answer in the case of a multiple choice type, the computer device 200 may generate and utilize a plurality of questions. To this end, the computer device 200 may extract two or more pieces of information stored in the database in step 420, and create two or more problems each having two or more pieces of information as a correct answer in step 430. In addition, the computer device 200 may improve security by allowing the user's account to be authenticated when correct answers are input to all of the two or more questions in step 450 . In addition, the computer device 200 may check macro detection as a countermeasure against a brute force attack by a hacking bot and reflect the macro detection result when authenticating an account. A brute force attack by a hacking bot may refer to an attack by a macro program that repeats problem solving until the hacking bot answers the problem correctly, and macro detection may be a technique for detecting the use of such a macro program. . For example, when the use of a macro program is detected in a terminal inputting an answer to a question, the computer device 200 may determine that user authentication has failed even if the terminal inputs the correct answer to the question. Conversely, the computer device 200 may determine that user authentication is successful when the terminal inputting the answer to the question does not detect the use of a macro program, and the terminal inputs the correct answer to the question. Even if m (m is a natural number) multiple-choice questions are used, the user simply selects an answer based on memory (for example, clicking the area where the selected answer is displayed with the mouse in the PC environment, or displaying the selected answer with the finger in the touch screen environment). The user's account can be authenticated with only m inputs by touching the area. Accordingly, the computer device 200 can obtain both convenience and security for user account authentication by appropriately setting m.

5 to 7 are diagrams illustrating examples of problems presented according to an embodiment of the present invention.

5 is an example of a user account authentication screen 510, in a specific game in which an island is given as the user's area in the game (1) of the user's information collected as information about game objects stored in association with the user's identifier An example of multiple-choice questions created through island images is shown. In this case, when the user selects his/her island image, authentication of the user account may be performed. If the user selects an island image other than the user's island image, authentication of the user account may fail.

The multiple-choice problem may basically include one correct answer and two or more incorrect answers, but is not limited thereto. As an example, FIG. 5 shows an example in which a multiple-choice question including three incorrect answers is presented. At this time, the "None" button may be used to refresh (or reselect) the view when there is no one's island among the presented views for the multiple-choice problem. In other words, in relation to a multiple-choice question presented with three options, a question may be generated so as to randomly select three out of four or more options including one correct answer and three or more incorrect answers. In this case, security can be improved by lowering the probability that a randomly selected answer is the correct answer.

As already explained, wrong answers can have different values of the same kind as correct answers. For example, in relation to the problem of finding the dungeon name, the correct answer to the problem of finding the name of the dungeon in which the user participated the most may be the name of the dungeon in which the actual user participated the most, and an incorrect answer may be the name of the dungeon in which the user participates the most. It may be the name of a dungeon in which the user participated less or the name of a dungeon in which the user did not participate at all. As another example, regarding the problem of finding the user's own character deck information, a correct answer may be the user's character deck information, and an incorrect answer may be another user's character deck information. In addition, game information set by the user, game information not set by the user, geographical location where the user has recently logged in to a game, and geographical location where the user has not logged in can be used as correct and incorrect answers, respectively.

6 is an example of a user account authentication screen 610, and (6) shows an example in which multiple-choice questions are generated through chatting contents collected as information on text input by a user in game contents. In this case, the user account can be authenticated by selecting the chat content that the user most recently entered into the chatting window on the game. If the user selects a chat content other than the most recently entered chat content in the chat window in the game, authentication of the user account may fail.

7 is an example of a user account authentication screen 710, (3) an example in which multiple choice questions are generated through information about other users collected as information about other users with whom the user has a personal relationship established within the game content represents In this case, when the user selects another user other than the user's guild member, authentication of the user account may be performed. If the user selects a guild member, authentication of the user account may fail.

According to an embodiment, the computer device 200 uses information about other users with whom the user has a personal relationship established within the game content or information about other users with whom the user has a personal relationship established with the game content on a social network associated with other users. You can request authentication for the user. For example, the computer device 200 may request other users who have established a personal relationship with the user who entered the correct answer to the problem to authenticate the user, and provide a channel for conversation with the user to other users who have accepted the request. can do. In addition, the computer device 200 may provide a function that allows other users to select whether or not to authenticate the user through a corresponding channel. At this time, the computer device 200 may further use a response from another user through the provided function to authenticate the user's account. For example, the computer device 200 may authenticate the user's account when another user selects that the user is the person with whom he or she had a conversation through the function.

In this way, according to embodiments of the present invention, an account can be authenticated based on knowledge using game content-related information that a user already knows.
