[0002] At present, there are cases of cheating by using secret codes in chess and card games. For example, in the current round of playing cards, sending a tea pouring emoticon to teammates means that teammates need to play bombs, and sending a three-stick emoticon to teammates means that teammates need to play three and bring one. In order to avoid the above situation, the anti-cheating methods in the prior art usually force users to turn on the microphone and camera. For example, in the competition, chess players are required to use laptops or desktops with cameras and microphones to play the game. This method requires additional equipment, which increases the cost of the game and the burden on the game server; or the game itself does not provide communication or prohibits communication, but this method seriously affects the user's experience in the game. Summary of the invention

[0035] Figure 1A process diagram of a cloud game anti-cheating method provided by the present disclosure Figure 1 ,like Figure 1 As shown, a cloud game anti-cheating method according to an embodiment of the present disclosure includes:

[0036] S111, identifying a valid game area in a game screen of a current game;

[0037] The server identifies the valid game area in the game screen of the current game, where the valid game area refers to the area in the game screen that the user needs to present to himself and other users in the game when playing the game, and the user and other users in the game need to judge further game operations based on the content presented in this area. For example, in a chess and card game, the user's card-playing area and the user's own hand area belong to the valid game area, while the area for displaying emoticons and the chat dialogue area do not belong to the valid game area. This part of the area belongs to the interactive experience area, and the user cheats by transmitting secret codes in the interactive experience area.

[0038] S112, copying the video stream of the current game to obtain a copied video stream;

[0039] Copy the video stream of the current game to obtain a copied video stream.

[0040] S113, superimposing the video stream of the effective game area of ​​the current game on the copied video stream for real-time playback, and the copied video stream is played with a delay of a preset time.

[0041] Among them, the preset time is set according to the game settings, and it is required that the preset time must be greater than or equal to the specified time for the user to perform game operations. For example, in chess and card games, there is a system-specified time for playing cards. If the time is exceeded, the system will automatically play the cards.

[0042] In the disclosed embodiment, the server identifies the valid game area in the game screen of the current game; and copies the video stream of the current game into a copy of the video stream; the video stream of the valid game area of ​​the current game is superimposed on the copy of the video stream and played in real time, and the copy of the video stream is played after a preset delay. This solution plays the video stream in the valid game area in real time, and delays the playback of the video stream outside the valid game area. Even if a user cheats by sending emoticons or other secret codes, the secret code cannot be transmitted to the other party's client before the user makes the next game operation. Without the need for additional equipment, anti-cheating in online games can be achieved more simply and timely, and the impact on user communication in the game is also relatively small, ensuring user experience.

[0043] Figure 2 A process diagram of a cloud game anti-cheating method provided by the present disclosure Figure 2 ,like Figure 2As shown, a cloud game anti-cheating method provided by the embodiment of the present disclosure includes the following steps:

[0044] First, assume that all users are cheating, and start from the cheater's end and perform the following operations:

[0045] Step S201, the server identifies a valid game area in the game screen of the current game;

[0046] The effective game area refers to the area on the game screen that the user needs to present to himself and other users in the game when playing the game, and the user and other users in the game need to judge further game operations based on the content presented in this area. For example, in a chess and card game, the user's card-playing area and the user's own hand area belong to the effective game area, while the area for displaying emoticons and the chat area do not belong to the effective game area.

[0047] Figure 3 A schematic diagram of a game screen in a cloud game anti-cheating method provided by an embodiment of the present disclosure, such as Figure 3 As shown, for chess and card games, the server finds the card-playing area in the game screen ( Figure 3 In the embodiment disclosed herein, the effective game area is the card-playing area framed by the dotted lines and the user's own hand area.

[0048] The card-playing area can be determined by comparing the previous and next frames to find the boundary where the pixels change, forming a rectangle, which is the card-playing area. In the disclosed embodiment, the effective game area in the game screen of the current game is identified by the following method:

[0049] Image acquisition: For a single game, the server captures the current image frame (game screen screenshot) every 1 second. For example, if the game lasts 5 minutes, a total of 300 images (width*height) are obtained.

[0050] Image preprocessing: For each frame, perform some grayscale preprocessing to obtain a width*height matrix with pixel values ​​0-255.

[0051] Pixel difference calculation: The pixel difference of corresponding positions is the key to finding the changed area. This is achieved by calculating the absolute difference between corresponding pixels of the two images, that is, |pixel1-pixel2|.

[0052] Threshold processing: Use a threshold for binarization, with an empirical value of 30. Differences exceeding the threshold are considered changes, and changes are set to 1, and no changes are set to 0, resulting in a 0,1 matrix A of width*height.

[0053] Connected region analysis: traverse the 0, 1 matrix A, identify the areas with the same and adjacent pixel values, and obtain the 0, 1 matrix B of width*height.

[0054] Mark the changed area: Traverse B to find the largest rectangle (with the largest number of 0s) in the changed area and mark it on the image, which is the red rectangle in the figure.

[0055] Step S202, copying the video stream of the current game to obtain a copied video stream;

[0056] After identifying the valid game area, the video stream A of the current game is copied to the video stream B (copying the video stream), that is, the instance copy of the cloud game.

[0057] The basic principle of cloud gaming is that the user sends a command stream to the cloud, which performs rendering and encoding and returns the video stream. This step implements instance replication, that is, saving the current game session and archive, persisting them to cloud storage or database, opening the game in the remaining idle instances and reading the session and archive, so that a single user's command stream is sent to two cloud instances at the same time to achieve replication.

[0058] Step S203: Video stream A retains the part of the valid game area, deletes the rest, and video stream A is superimposed on video stream B;

[0059] Video stream A displays the part outlined by the red frame, and deletes the rest. Video stream A is superimposed on video stream B. The main implementation logic of the above deletion is pixel interception. The server selects the cropping area (according to the coordinates of the four vertices of the red frame rectangle, the X min , X max , Y min , Y max ), extract the pixel data of the area through pixel interception operation. Further operations on the pixel array of the video frame are performed to retain only the pixel values ​​of the specified area and remove other areas, that is, to save the video frame smaller than X. min or Y min , greater than X max or Y max The pixels in the area are cleared. The above is a single-frame operation. For video, this operation is performed on each frame.

[0060] The main implementation logic of overlay is pixel coverage. The pixel values ​​of the cropped video stream A are replaced with the pixel values ​​of the corresponding positions of the video stream B according to the coordinates to achieve overlay. The output video stream is the final effect of video stream A after cropping and superimposed on video stream B.

[0061] Step S204, superimposing the video stream of the effective game area of ​​the current game on the copied video stream for real-time playback, and playing the copied video stream after a preset delay;

[0062] Figure 4 A schematic diagram of delayed playback of a copied video stream in a cloud game anti-cheating method provided by an embodiment of the present disclosure, such as Figure 4 As shown, the upper area is the video stream playback area, the lower area is the video stream preview area, the central area of ​​the video stream playback area plays video stream B, and the area outside the central area plays video stream A. For example, in the video stream preview area, video stream A plays normally, and video stream B plays with a delay of 10 seconds, that is, the video frame timestamps of video stream B are all increased by 10 seconds, and video stream A and the delayed video stream B are time-aligned.

[0063] The main operation of the server is: the server establishes a cache delay queue. On the queue, the data structure is mainly in the form of string + timestamp. When receiving the instruction stream, the instruction stream is stored in the string position in the queue, and the current time A to the timestamp position is recorded. A background thread or timer is used to poll the timestamps of all instructions in the queue every second. If the time of the instruction timestamp = current time - 10 seconds, it means that the instruction is actively delayed and aligned with the current time. The instruction is taken out of the queue and sent to the cloud for rendering to achieve video stream delay.

[0064] After the processing of steps S201-S204, it is achieved that from the user's perspective, the card-playing area and the personal hand area (i.e., the effective game area) are real-time; while the expression area and the chat area are delayed. Even if there is cheating by the player, the cheating screen information cannot be transmitted to the other terminal side in real time, and therefore the cheating cannot be successful.

[0065] Step S205: determine whether the user currently turns on background sound;

[0066] Through the output of the current audio stream of the game and the configuration information in the game archive (the user's configuration in cloud games is stored in the cloud, and whether to turn on background sound is one of the options), it can be determined whether the user currently has background sound turned on.

[0067] The corresponding game archive is generally a text file, such as:

[0068] [config]

[0069] Bgm=1

[0070] Step S206: If the user turns on the background sound, generate an opposite waveform for the background sound, superimpose the current audio stream C to eliminate the background sound D, and generate a new audio stream E;

[0071] Based on the digital audio of the background sound obtained in step S205, waveform analysis is performed on the audio to obtain the phase information of each frame, and each frame of the audio is phase-inverted by multiplying the phase value by -1, and the phase-inverted audio frames are reassembled into a complete audio file.

[0072] Step S207, delay the playback of audio stream E by 10 seconds, and then add background sound D (in the process of clouding the game, a folder is designated to store background sound files) to generate the final output audio stream F;

[0073] The logic of superposition mainly includes: taking the amplitude at the same time point through the digital signals of audio stream E and audio stream D, adding them to obtain a new amplitude, that is, the amplitude values ​​E(t) and D(t), and the superposition (addition) C(t) will be: C(t)=E(t)+D(t), and the result will be a new audio signal, which contains all the superimposed audio.

[0074] Through steps S205-S207, delayed playback of sound effects is achieved. The background sound is real-time, and the sound effect part is delayed (synchronized with the picture of the emoticon package). If there is cheating by the player, the sound information containing the cheating information cannot be transmitted to the other terminal side in real time.

[0075] Step S208, collecting the game data of the user before and after the steps S201-S207 are implemented;

[0076] The user's game data includes: records of sending emoticons, records of sending quick chats, room attributes, game results, game retention, etc.

[0077] Among them, single user data includes:

[0078] Number of sent expression records X1 (via server-side logging);

[0079] Send quick chat records X2 (via server-side logging);

[0080] Room attributes x3 (enumeration: 1 for individual play, 1 for friends play, 2 for experience points) (through server-side logging);

[0081] Number of wins x 4 (through personal records);

[0082] Number of losses x5 (according to personal records);

[0083] Total duration X6 (by personal record);

[0084] Second-round retention rate X7 (based on personal records);

[0085] Next-day retention rate X8 (through personal records);

[0086] All user data includes:

[0087] Number of sent expression records AVG1;

[0088] Send quick chat history AVG2.

[0089] Step 209: For users whose user behaviors f(x) differ greatly (e.g., greater than 50%) before and after anti-cheating is implemented, continue to execute steps S201-S207;

[0090]

[0091] Step 210: If the number of user behaviors is similar before and after the implementation of anti-cheating, and the results of the games are not much different, the user behavior is judged to be normal behavior and a non-cheating user, and the real-time rendering of the video and audio streams is restored, and the user process starts from the trusted end.

[0092] At the same time, the user data of the user in step S208 is also collected normally. If the number reaches the threshold, cheating is suspected and steps S201-S207 are repeated.

[0093] In the disclosed embodiment, the server identifies the effective game area in the game screen of the current game; and copies the video stream of the current game into a copy of the video stream; the video stream of the effective game area of ​​the current game is superimposed on the copy of the video stream and played in real time, and the copy of the video stream is played after a preset delay. This solution plays the video stream in the effective game area in real time, and delays the playback of the video stream outside the effective game area. Even if a user cheats by sending emoticons or other secret codes, the secret code cannot be transmitted to the other client before the user makes the next game operation; and further adopts the real-time playback of the background sound in the audio stream of the current game, and the delayed playback of the sound effect sound in the audio stream of the current game to prevent the cheating of the sound effect sound; and further by judging whether the user has cheating behavior, executing whether to perform anti-cheating operations, and continuously looping judgments, it is possible to achieve anti-cheating in online games more simply and timely. The above solution does not require additional equipment, and at the same time has little impact on user communication in the game, ensuring user experience.
