[0030] Embodiment one

[0031] Referring to Figure 1 , a flowchart of a method for detecting an external plug-in of a table tennis game is shown, which can be executed by a table tennis game external plug-in detection device. The table tennis game external plug-in detection device can be realized in the form of hardware and / or software, and can be configured in an electronic device. As shown in Figure 1 , the method comprises:

[0032] Step 101, in the client, load the game physics engine of the table tennis game program, collect the hitting information generated when hitting the table tennis from the game physics engine, and send the hitting information to the server.

[0033] In actual application, a plurality of game programs can be integrated in the client in the manner of Flutter, ReactNative, Web, Hybrid, etc., especially some small game programs.

[0034] The game physics engine, such as Box2D, is configured in the client to support the running of a plurality of game programs.

[0035] The user can log in his account in the client, and select the table tennis game program from a plurality of game programs in the client. At this time, the game physics engine can be loaded to load the table tennis game program to run, wherein the table tennis game program is a game program simulating table tennis.

[0036] Different clients can participate in the same billiards game in the billiards game program through random matching, inviting friends, etc.

[0037] At present, the external plug-ins developed for the billiards game program are mostly to modify the physical parameters of the billiards game program for simulating billiards, such as the size of the billiards, the force of the hitting, the angle of the hitting, the friction coefficient, the trajectory of the collision, etc.

[0038] To this end, the embodiment performs initial anti-external plug-in verification on the game physics engine in the client, so that not only part of the anti-external plug-in operation can be shared in the client to reduce the computing power burden of the server, but also the behavior consistency verification of the same account when logging in on multiple devices (such as PC (personal computer), mobile terminal) can be adapted.

[0039] In the process of initial anti-external plug-in verification in the client, the hitting information generated by the current client when hitting the billiards each time can be collected from the game physics engine and sent to the server.

[0040] The hitting information includes the first billiard state information after hitting, and the first billiard state information is the state of the billiard table and each billiard when the billiard is still after hitting.

[0041] Exemplarily, the first billiard state information includes the size of the billiard table, the position of each billiard, etc.

[0042] Step 102, in the client, detecting the validity of the physical parameters for simulating billiards in the game physics engine, and sending alarm information to the server when the validity is invalid.

[0043] In the process of initial anti-external plug-in verification in the client, the validity of the physical parameters for simulating billiards in the game physics engine can be detected in real time, and when the validity is invalid, it indicates that the physical parameters for simulating billiards in the game physics engine may be tampered with. At this time, the client generates an alarm information and sends the alarm information to the server.

[0044] In an embodiment of the application, step 102 can include the following steps:

[0045] Step 1021, calling a callback function in the game physics engine when updating the billiards game program each frame.

[0046] In actual application, a probe implantation layer can be set in the game physics engine, that is, some key nodes are screened out in the game physics engine to inject monitoring code.

[0047] In the embodiment, a detection function can be set in the callback function for updating the billiards game program each frame in the game physics engine, and the monitoring code is injected.

[0048] Exemplarily, in the Box2D physics engine, the physical simulation is in units of "steps", and each time the onStep function (or the b2World::Step function) is called, the Box2D physics engine performs custom logic and calculates the physical state (such as position, velocity, collision, etc.) once.

[0049] In the present example, the detection function checkValid can be set in the onStep function, and the monitoring code is injected.

[0050] Then, the callback function is called each time the billiards game program is updated in the game physics engine, and since the callback function includes the detection function, the detection function is called synchronously at this time.

[0051] Step 1022, calling the detection function to detect the validity of the physical parameters for simulating billiards in the game physics engine.

[0052] In the process of running the detection function, the validity of the physical parameters for simulating billiards in the game physics engine is detected according to the detection logic defined by the detection function.

[0053] In an embodiment of the present application, step 1022 can further include the following steps:

[0054] Step 10221, reading the physical parameters of multiple types for simulating billiards from the memory of the game physics engine.

[0055] In the present embodiment, the detection function queries the memory allocated by the game physics engine, especially the memory address of the physical parameters for simulating billiards in the game physics engine, and reads the physical parameters of multiple types for simulating billiards from the memory allocated by the game physics engine in real time.

[0056] Step 10222, determining the standard parameters of multiple types for simulating billiards.

[0057] In the detection function, a set of physical parameters of multiple types for simulating billiards is built in, and the physical parameters of the detection function are independent of the physical parameters of the game physics engine and can be used as a standard for checking the physical parameters of the game physics engine. Therefore, the physical parameters of the detection function can be referred to as standard parameters.

[0058] In a specific implementation, the physical parameters of the detection function are encrypted in a symmetric key algorithm or the like, forming parameter ciphertext pre-embedded in the detection function. Therefore, the detection function can load the pre-set parameter ciphertext into the memory allocated by the detection function, decrypt the parameter ciphertext using a symmetric key algorithm or the like, and obtain the standard parameters of multiple types for simulating billiards.

[0059] Step 10223, for the same type, calculate the parameter difference between the physical parameter and the standard parameter.

[0060] Generally, the decryption process of the symmetric key algorithm is bit-level accurate matching. If the key and the ciphertext are stored or calculated using floating-point numbers, the precision error may cause:

[0061] 1. Key value deviation: for example, 1.23456789 is actually stored as 1.2345679, and the correct key cannot be restored during decryption;

[0062] 2. Inconsistent intermediate results: for example, different results are generated due to floating-point error in modulus operation and bit shift operation.

[0063] Therefore, for the same type, the absolute value of the difference between the physical parameter and the standard parameter can be taken to obtain the parameter difference between the physical parameter and the standard parameter.

[0064] The parameter difference corresponding to the physical parameter of each type is compared with the error threshold value corresponding thereto, wherein the error threshold value is usually a very small value, such as 0.000000001.

[0065] Step 10224, if the parameter differences of multiple types are all less than the preset error threshold value, it is determined that the validity of the physical parameter is valid.

[0066] If the parameter differences of multiple types are all less than the corresponding error threshold value, it indicates that the physical parameters of multiple types are within a reasonable error range, and the risk of tampering is low, and then it is determined that the validity of the physical parameter is valid.

[0067] Step 10225, if the parameter differences of at least one type are all greater than or equal to the preset error threshold value, it is determined that the validity of the physical parameter is invalid.

[0068] If the parameter differences of at least one type are all less than the corresponding error threshold value, it indicates that the physical parameters of at least one type are outside a reasonable error range, and the risk of tampering is high, and then it is determined that the validity of the physical parameter is invalid.

[0069] If the validity of the physical parameter is detected, the parameter ciphertext and the standard parameter are released from the memory to ensure security.

[0070] In an embodiment of the present application, step 1022 can further include the following steps:

[0071] Step 10226, determine the timer.

[0072] Step 10227, compare the time length with the preset time threshold value; when the time length is greater than or equal to the time threshold value, execute steps 10221-10225.

[0073] Tampering with the physical parameters of the game physics engine is usually a long-term behavior, in order to reduce the resource occupation of the client, a timer can be set in the game physics engine, which is used to count the time interval from the last detection of the validity of the physical parameters, that is, the timer is reset every time the detection of the validity of the physical parameters is completed.

[0074] The detection function reads the time interval from the last detection of the validity of the physical parameters from the timer, compares the time interval from the last detection of the validity of the physical parameters with a preset time threshold (such as 50 ms), and when the time interval from the last detection of the validity of the physical parameters is greater than or equal to the time threshold, detects the validity of the physical parameters in the game physics engine, and when the time interval from the last detection of the validity of the physical parameters is less than the time threshold, continues to wait.

[0075] Step 103, in the service end, comparing the first table ball state information of the opponent end, obtaining the ball hitting comparison information.

[0076] The service end filters the first table ball state information of the opponent end for secondary anti-hacking verification when receiving the first table ball state information sent by each client, and compares each item of data in the first table ball state information of the opponent end to obtain the ball hitting comparison information.

[0077] The opponent end is a client participating in the same table ball game.

[0078] Step 104, in the service end, when the alarm information and the ball hitting comparison information satisfy the preset detection condition, detecting whether the opponent end uses the external plug-in to modify the table ball game program according to the ball hitting information of the opponent end.

[0079] The service end maintains two data streams for the opponent end, one of which is the alarm information and the other of which is the ball hitting comparison information.

[0080] The service end compares the two data streams to trigger three anti-hacking verifications, specifically, when the alarm information and the ball hitting comparison information satisfy the preset detection condition, detecting whether the opponent end uses the external plug-in to modify the table ball game program according to the ball hitting information of the opponent end.

[0081] In the service end, when the alarm information appears and the ball hitting comparison information is the same as the first table ball state information, that is, the result of the first anti-hacking verification is different from the result of the second anti-hacking verification, it is determined that the opponent end (user) is suspected of using the external plug-in to modify the table ball game program.

[0082] In the recent period of time, if the frequency of a same user suspected of using the external plug-in to modify the table ball game program exceeds a preset frequency threshold, it can be determined that the user is suspected of using the external plug-in to modify the table ball game program.

[0083] Exemplarily, the detection condition comprises at least one of the following:

[0084] The ball hitting comparison information is that the first table tennis state information of the battle end is different, and the alarm information appears at the same time.

[0085] The ball hitting comparison information is that the number of times that the first table tennis state information of the battle end is the same is greater than or equal to a preset frequency threshold.

[0086] The former detection condition indicates that the primary anti-external hanging check and the secondary anti-external hanging check both show alarms, and the risk of the client using external hanging is higher. The latter detection condition indicates that the client is subjected to random inspection.

[0087] In an embodiment of the present application, the ball hitting information further comprises second table tennis state information before the ball hitting and a ball hitting operation instruction, wherein the second table tennis state information describes the state of the table and each table tennis when the table tennis is static before the ball hitting, and the ball hitting operation instruction comprises a ball hitting direction, a ball hitting strength and the like. Exemplarily, the second table tennis state information comprises the size of the table, the position of each table tennis and the like.

[0088] The game physics engine has loaded the table tennis game program.

[0089] Therefore, in the present embodiment, step 104 can comprise the following steps:

[0090] Step 1041, controlling the game physics engine to execute the ball hitting operation according to the ball hitting operation instruction on the basis of the second table tennis state information, and obtaining third table tennis state information.

[0091] The server can send the second table tennis state information and the ball hitting operation instruction to the game physics engine deployed thereby, control the game physics engine to execute the ball hitting operation according to the ball hitting operation instruction on the basis of the second table tennis state information, and obtain third table tennis state information.

[0092] The third table tennis state information describes the state of the table and each table tennis when the table tennis is static after the ball hitting.

[0093] Exemplarily, the third table tennis state information comprises the size of the table, the position of each table tennis and the like.

[0094] Step 1042, calculating a first difference value between the first table tennis state information of the battle end in the table tennis distribution.

[0095] In the present embodiment, the first table tennis state information of the battle end can be compared, and the first difference value between the first table tennis state information of the battle end in the table tennis distribution can be calculated.

[0096] In practical application, the first table ball state information includes positions of each table ball, and each table ball has an ID or the like identifier.

[0097] The absolute values of the differences between the positions of the same table ball on the battle side are obtained to obtain first ball deviation values.

[0098] The first ball deviation values corresponding to each table ball are compared.

[0099] The first ball deviation value with the largest value is screened out as a first difference value between the first table ball state information of the battle side in table ball distribution.

[0100] If the client A and the client B are the battle side, the first difference value can be expressed as Delta(A, B) = Max(abs(ai-bi)), wherein Delta(A, B) is the first difference value of the client A and the client B, ai is the i-th table ball in the client A, bi is the i-th table ball in the client B, abs is an absolute value function, and MAX is an absolute value function.

[0101] In step 1043, if the first difference value is greater than or equal to a preset difference threshold, a second difference value between the third table ball state information and the first table ball state information of the battle side in table ball distribution is calculated.

[0102] The first difference value is compared with the preset difference threshold (for example, 0.5).

[0103] If the first difference value is greater than or equal to the difference threshold, it is indicated that the difference in the hitting result of the battle side is large, and the possibility that at least one battle side uses an external plug-in is high, and then the second difference value between the third table ball state information of the service side and the first table ball state information of each battle side in table ball distribution is calculated.

[0104] In practical application, the third table ball state information includes positions of each table ball, and each table ball has an ID or the like identifier.

[0105] The absolute values of the differences between the positions of the same table ball on the battle side are obtained to obtain first ball deviation values.

[0106] The first ball deviation values corresponding to each table ball are compared.

[0107] The first ball deviation value with the largest value is screened out as a first difference value between the third table ball state information and the first table ball state information of the battle side in table ball distribution.

[0108] Supposing that client A and client B are the game ends, and C is the service end, then the second difference value can be expressed as Delta(A, C) = Max(abs(ai-ci)), Delta(B, C) = Max(abs(bi-ci)), wherein Delta(A, C) is the second difference value of client A and service end C, Delta(B, C) is the second difference value of client B and service end C, ai is the i th table ball in client A, bi is the i th table ball in client B, ci is the i th table ball in service end C, abs is the function of taking absolute value, and MAX is the function of taking absolute value.

[0109] Step 1044, if the second difference value is greater than or equal to the preset difference threshold, it is determined that the game end uses the external plug-in to modify the table ball game program.

[0110] The second difference value corresponding to each game end is compared with the preset difference threshold.

[0111] If the second difference value corresponding to a certain game end is greater than or equal to the preset difference threshold, it is determined that the game end (user) uses the external plug-in to modify the table ball game program.

[0112] If the game end using the external plug-in to modify the table ball game program is the serving end, the third table ball state information simulated by the service end is synchronously sent to the serving end, the serving end is prompted to commit a foul, and another game end (i.e. non-serving end) re-serve.

[0113] If the game end using the external plug-in to modify the table ball game program is the non-serving end, the third table ball state information simulated by the service end is synchronously sent to the non-serving end, the non-serving end is prompted to commit a foul, and the first table ball state information of the serving end is used as the criterion to continue the table ball game.

[0114] For the case that the client uses the external plug-in to modify the table ball game program, the client is suspected to use the external plug-in to modify the table ball game program, etc., the user can be processed according to the business rules.

[0115] In one case, if it is determined that the user uses the external plug-in to modify the table ball game program, the user can be listed as an abnormal user, and the game permission (such as matching queue, joining the game) is limited differently according to the number of times of using the external plug-in to modify the table ball game program, for example, when the number of times of using the external plug-in to modify the table ball game program reaches 3 times, the user enters the matching queue of the abnormal user in the future 14 days, and is prohibited from joining the game for 4320 minutes.

[0116] In another case, if it is determined that the user is suspected of using the external plug-in to modify the table tennis game program, different restrictions are imposed on the game authority (such as matching the queue and joining the game) according to the number of times of suspected use of the external plug-in to modify the table tennis game program. For example, if the number of times of suspected use of the external plug-in to modify the table tennis game program exceeds 10 times, the user will enter the matching queue of the abnormal user for 7 days in the future, and if the number of times of suspected use of the external plug-in to modify the table tennis game program exceeds 30 times, the user will be prohibited from joining the game for 720 minutes.

[0117] Of course, an appeal channel can be established, and when the user promises not to use the external plug-in to modify the table tennis game program in the future, the restriction on the game authority can be relaxed.

[0118] After the method in the embodiment is put into use, the number of users using the external plug-in of the table tennis game program is reduced from more than 1700 to a single digit, the initial violation rate is reduced from 0.5% to 0%, and part of the external plug-in manufacturing groups of the table tennis game program give up the external plug-in project of the table tennis game program and no longer update the external plug-in of the table tennis game program.

[0119] In the embodiment, in the client, a game physics engine of the table tennis game program is loaded, and hit information generated when a table tennis ball is hit is collected from the game physics engine and sent to the server; the hit information includes first table tennis state information after the hit; in the client, the effectiveness of the physical parameters for simulating the table tennis in the game physics engine is detected, and when the effectiveness is invalid, an alarm information is sent to the server; in the server, the first table tennis state information of the battle end is compared to obtain hit comparison information; the battle end is a client participating in the same table tennis game; in the server, when the alarm information and the hit comparison information satisfy a preset detection condition, whether the battle end uses the external plug-in to modify the table tennis game program is detected according to the hit information of the battle end. The embodiment establishes a three-level anti-external plug-in verification from the client to the server, which not only can verify the external plug-in that modifies the table tennis game program at the game physics engine level, avoids bypassing or rootkit hiding, improves the accuracy of external plug-in detection, and the client and the server have clear division of labor, which can reduce the computing power cost of the server.
