Description

Method for checking legality of virtual items, method for transferring virtual items, and game system

technical field

The invention relates to a technology for ensuring the security of a network application system, in particular to a method for checking the legality of virtual items, a method for transferring virtual items and a game system.

Background technique

With the development of the Internet, online games are becoming more and more popular, and various problems of virtual items in games are becoming more and more prominent. Virtual items refer to equipment, pets, etc. in the game. Game users usually spend a lot of time and communication costs in order to obtain these virtual items. Therefore, if the game system mishandles and manages the user's virtual items improperly, it will greatly affect the user's satisfaction.

There are two main types of operations on virtual items: the user obtains virtual items through the client to the game server, and the transfer of virtual items between different users through their respective clients.

Referring to FIG. 1, FIG. 1 is a schematic structural diagram of a game system in the prior art. Wherein the user data table is stored in the database 101, and this data table stores the user's information, for example: the main information of " user 1 " and " user 2 " stored in the user data table shown in table 1, other information has nothing to do with the present invention relationship, so Table 1 does not show it. User ID game logo virtual item identification user 1 Game A virtual item a user 2 Game B virtual itemb

Table 1

The game server 102 stores the game logic, accepts operations such as login, registration, and joining the game performed by the user through the client 103, and performs corresponding processing.

At present, the user executes the game program through the client 103, logs in to the game server 102, and after joining the game, obtains virtual items through game logic, and realizes the transfer of virtual items between different users.

It can be seen from Table 1 that since the data of the virtual item in the current game does not have any identification information, it is impossible to tell from the data whether the virtual item is indeed recognized by the system, nor whether it really belongs to the user specified in the data , but can only analyze the answers to these two questions from the logs saved by the system. In this case, once a database is illegally invaded, it is easy to copy, steal by modifying the corresponding records of virtual items, and even create some counterfeit virtual items that are not recognized by the system. Because the user cannot identify the legitimacy of a certain virtual item as soon as possible, it brings certain risks to the user to transfer the virtual item. For example: the user obtains these counterfeit virtual items, which will be deleted by the system sooner or later, and the time, energy and communication costs paid by the user are wasted in vain.

That is to say, the data management of virtual items in the game is too simple, resulting in the problems of easy copying, theft and poor anti-counterfeiting of virtual items.

And the game server 202, after receiving the virtual item transfer request sent by the client 203, or after receiving the virtual item legitimacy check request sent by the client 203, determines that the virtual item for which the request needs to be checked for legality, and will It is only necessary to check the legality of the virtual item information or the information before and after the transfer of the virtual item to be transferred, and send it to the issuing server 204; and after receiving the inspection result returned by the issuing server 204, perform the virtual item transfer operation or check The result is returned to the client 203.

The issuing server 204 generates and stores the issuer verification information and the owner verification information of the virtual item according to the virtual item information requested by the client; Perform legality check with the stored publisher verification information and attribution verification information, and return the check result to the game server 202, or further use the transferred virtual item information to generate new verification information to update the stored verification information and attribution information.

In this embodiment, the issuing server 204 can store and update the verification information in two ways: first, the issuing server 204 directly stores the virtual item and its verification information in the database 201 correspondingly. In the second way, the issuing server 204 returns the verification information of the generated virtual item to the game server 202, and the game server 202 stores the virtual item and its verification information in the database 201 correspondingly.

In this embodiment, the database 201 is the user data storage device, which stores the user data table, which contains the verification information of the virtual item, for example: "user 1" and "user 2" stored in the user data table shown in Table 2 The main information of ", other information has nothing to do with the present invention, so table 2 does not show. User ID game logo virtual item identification Publisher Verification Information Attribution Verification Information user 1 Game A virtual item a 1A3 1Aa5 user 2 Game B virtual itemb 2B4 2Bb6

Table 2

In this embodiment, the issuing server 202 can obtain the stored virtual item verification information from the database 201, and check the validity of the virtual item.

The method for checking the validity of the virtual item and transferring the virtual item in the embodiment shown in FIG. 2 will be described in detail below.

First, the process of generating verification information by the issuing server in this embodiment will be described in detail.

Referring to FIG. 3 , FIG. 3 is a flow chart of the process of distributing virtual items by the game server in the embodiment shown in FIG. 2 . The process includes the following steps:

Step 301, the client sends a virtual item request to the game server.

Step 302, the game server checks the legality of the received virtual item request, and if the check passes, execute step 303, otherwise, return a prompt that the request is illegal to the client, and end the process.

In this step, the game server can check the legality of the request in various ways, for example: according to the message identifier contained in the request, check whether the request is a message that can be received by itself, and if so, it is a legal request; or Calculate the checksum, and compare the calculated checksum with the checksum included in the request. If they are the same, it is a legal request.

Step 303, the game server sends the virtual item information to the issuing server along with a request for generating virtual item verification information.

The virtual item information includes: the ID of the virtual item to be allocated and the ID of the game to which it belongs, and the user ID of the client requesting the virtual item.

In step 304, the issuing server checks the validity of the request for generating virtual item verification information, and if the check is passed, executes step 305; otherwise, returns a prompt that the request is illegal to the game server, and ends the process.

In this step, the issuance server can verify the validity of the request by using the same method as the game server in step 303 to verify the validity of the request, which will not be repeated here.

Step 305, the issuing server generates verification information according to the virtual item information.

In this step, the issuing server may first use the virtual item ID and the game ID to which it belongs to generate publisher verification information, and then use the virtual item ID and user ID to generate owner verification information. In fact, which verification information is generated first does not affect the effect of this embodiment, and can be set arbitrarily.

Step 306, the distribution server returns the verification information to the game server, and responds to the request for obtaining the verification information.

In step 307, the game server checks the legality of the response information, and if the check passes, execute step 308; otherwise, it returns an illegal response prompt to the issuing server, and ends the process. The checking method is the same as step 303.

Step 308, the game server correspondingly stores the virtual item and the returned verification information into the database.

In this embodiment, the verification information is stored in the database by the game server. In practical applications, the verification information can also be directly stored in the database by the issuing server.

Step 309, the game server responds to the virtual item request to the client, and completes the distribution of the virtual item.

Referring to FIG. 4 , FIG. 4 is a flow chart of the issuing server in the process shown in FIG. 3 . The process includes the following steps:

Step 401 , check the validity of the request to generate virtual item verification information, and judge whether it is passed, if yes, execute step 402 , otherwise execute step 405 .

Step 402, use the virtual item ID and the game ID to which it belongs to generate publisher verification information.

Step 403, using the virtual item ID, the game ID to which it belongs, and the user ID to generate owner verification information.

In this embodiment, corresponding codes are set in advance for all game IDs, virtual item IDs and user IDs in the game system. The method for generating the publisher verification information in step 402 is: combine the codes corresponding to the received virtual item ID and the corresponding game ID to form the publisher verification information. The method for generating the attribution verification information in step 403 is: combining the received virtual item ID and the codes corresponding to the game ID and user ID to which it belongs, respectively, to form the attribution verification information.

In practical applications, a fixed code indicating a non-system game, a fixed code for a non-system virtual item, and a code for a non-system user are also set. When the virtual item ID or game ID in the received virtual item information or User ID, if no corresponding code is found, combine the above fixed codes into the verification information. In this way, when checking the legality of virtual items, verification information is generated for the virtual items to be checked. If the virtual items to be checked are non-system games or non-system virtual items or non-system users, it can be reflected through the above fixed code , which is convenient for comparison with the stored verification information to determine the legitimacy of the virtual item.

Step 404: Reply the game server with success information, and end the process.

Step 405: Respond to the failure message of the game server, and end the process.

In this embodiment, it is assumed that the user data table is as shown in Table 2, and the specific encoding is as follows:

Codes of all games provided by this system: "Game A" is represented by 1, "Game B" is represented by 2, non-system games are represented by 3; codes of all virtual items in this system: "Virtual item a" is represented by A, "Virtual item b" is represented by B, and non-system virtual items are represented by C; the codes of all users of this system: "User 1" is represented by a, "User 2" is represented by b, and non-system users are represented by c.

Then, the specific process of generating the issuer verification information can be referred to FIG. 4 a , which is a flow chart of the issuing server generating the issuer verification information in the process shown in FIG. 4 . The process includes the following steps:

Steps 410-411, judge whether it is game A according to the received game ID, if yes, set the first digit of the publisher verification information to "1", and execute step 415; otherwise, execute step 412.

Steps 412-414, determine whether it is game B, if yes, set the first digit of the publisher verification information to "2", and execute step 415; otherwise, set the first digit of the publisher verification information to "3" .

Steps 415-416, judge whether it is virtual item a according to the received virtual item ID, if yes, set the second digit of the issuer verification information to "A", and execute step 420; otherwise, execute step 417.

Steps 417-419, determine whether it is a virtual item b, if yes, set the second digit of the issuer verification information to "B", and execute step 420; otherwise, set the second digit of the issuer verification information to "C" ".

Step 420, use the first and second digits of the issuer's verification information to generate a check digit as the third digit of the verification information, and end the process.

The specific process of generating the attributor verification information can be referred to FIG. 4 b , which is a flowchart of the process of generating the attribution verification information by the issuing server in the process shown in FIG. 4 . The process includes the following steps:

In steps 430-439, the first and second digits of the attribution verification information are generated according to the received virtual item ID and the game ID to which it belongs. This process is basically the same as steps 410-419 in FIG. 4a, except that step 440 is executed after the second bit of the verification information is set, which will not be described in detail here.

In steps 440-441, judge whether the user is user 1 according to the received user ID, if yes, set the third digit of the attribution verification information to "a", and execute step 445; otherwise, execute step 442.

Steps 442-444, determine whether it is user 2, if yes, set the third digit of the attribution verification information to "b", and execute step 445; otherwise, set the third digit of the attribution verification information to "c" .

Step 445, use the first, second, and third digits of the verification information of the owner to generate a check digit as the fourth digit of the verification information, and end the process.

The publisher verification information and the attribution verification information generated according to Fig. 4a and Fig. 4b are added to the user data table and stored in the database.

Then, the process of transferring virtual items by the user in this embodiment will be described in detail, which includes the process of checking the validity of the virtual items to be transferred.

Referring to FIG. 5 , FIG. 5 is a flow chart of the process of transferring virtual items by the user in the embodiment shown in FIG. 2 . The process includes the following steps:

In steps 501-502, the game server receives the operation request for transferring virtual items sent by the client of the user before the transfer, and interacts with the client of the user after the transfer to confirm the transfer operation, and confirms that the transfer belongs to the user.

Step 503, the game server sends the pre-transfer information and post-transfer information of the virtual item to be transferred to the issuing server together with the request for modifying the verification information of the virtual item. The pre-transfer and post-transfer information of the virtual item, except the information of the user after the transfer, can be obtained by querying the database.

Among them, the pre-transfer information of the virtual item to be transferred includes: the identifier of the virtual item to be transferred and the game ID to which it belongs, and the user ID of the client before the virtual item is transferred; the post-transfer information of the virtual item to be transferred includes: The virtual item ID and the game ID to which it belongs, and the user ID of the client after the virtual item is transferred.

In step 504, the issuing server performs a legality check on the request for modifying the verification information of the virtual item, and if the check is passed, then step 505 is executed; otherwise, step 509 is executed.

Step 505, the issuing server checks the legality of the virtual item to be transferred according to the pre-transfer information of the virtual item to be transferred and the stored publisher verification information, if the check is passed, the virtual item is a virtual item of a game approved by the issuing server , go to step 506; otherwise go to step 509.

In this step, the issuing server regenerates the issuer verification information with the virtual item information before the transfer, compares the newly generated issuer verification information with the issuer verification information of the virtual item obtained from the database, and determines whether they are the same, if they are the same, Then the check is passed; otherwise, it is not passed.

Step 506, the issuing server checks the legality of the virtual item to be transferred according to the pre-transfer information of the virtual item to be transferred and the stored attribution verification information, if the check is passed, the attribution information of the virtual item is correct, and step 507 is executed; Otherwise, execute step 509.

In this step, the issuing server regenerates the attribution verification information with the virtual item information before the transfer, compares the newly generated issuer verification information with the attribution verification information of the virtual item obtained from the database, and determines whether they are the same; if they are the same, Then the check is passed; otherwise, it is not passed.

Step 507, the issuing server generates new issuer verification information according to the post-transfer information of the virtual item to be transferred.

Step 508, the issuing server generates new verification information of the owner according to the post-transfer information of the virtual item to be transferred.

Step 509, the issuing server responds to the game server with a request for modifying the verification information of the virtual item. If the request legitimacy check fails or the virtual item legitimacy check fails, the response is a request failure response, and step 511 is directly performed; if the request legitimacy check passes and the virtual item legitimacy check also passes, the response is a request If the response is successful, the response includes new issuer verification information and new attributor verification information, and step 510 is executed.

Step 510, the game server modifies the data in the database according to the received response. Including: modifying the attribution information of the virtual item, that is, adding the virtual item to the transferred user, and adding new verification information in the transferred user data table.

In this embodiment, the game server comes to the database to modify data. In practical applications, the issuing server may directly modify data in the database after generating new verification information.

In step 511, the game server sends the result of success or failure of the transfer operation to the user before the transfer and the user after the transfer.

In practical applications, the barter transaction of virtual items can be realized through two transfer processes of virtual items. At the same time, since the virtual currency also belongs to the virtual item, the virtual item transaction with the virtual currency can also be realized through a transfer process of the virtual currency and a transfer process of the virtual item.

Referring to FIG. 6 , FIG. 6 is a flow chart of the issuing server in the process shown in FIG. 5 . The process includes the following steps:

Step 601 , check the validity of the request to modify the verification information of the virtual item, and judge whether it is passed, if yes, execute step 602 , otherwise execute step 604 .
