[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0046] Application scenario: when monitoring the interaction (such as data transmission) of a network game, some monitoring methods often have the problems of not comprehensive and not accurate monitoring; for example, some monitoring methods only monitor and analyze behaviors (such as abnormal moving track, attack mode, etc.), but ignore the monitoring of target objects (such as game characters or props, etc.) and target files (such as local files) in the network game. This monitoring method is easy to be bypassed by a game plug-in. Once the game plug-in bypasses the monitoring, it is easy to modify or replace the appearance of the target object or the target file to achieve the purpose of cheating, thereby causing great damage to the fairness of the game.

[0047] Please refer to Figure 1 The data transmission method for a network game provided by the embodiment includes the following steps:

[0048] S1, determining a target object of a network game, and determining a target file based on the target object;

[0049] S2, determining an update key point, and establishing a secure channel between the target object and the target file based on the update key point, wherein the update key point includes appearance features and logical features corresponding to the target object. It should be noted that the secure channel is established between the target object and the target file through the appearance features and the logical features. The secure channel corresponds to a plurality of secure tracks for monitoring the target object and the target file, and each secure track is deployed with a plurality of security probes for monitoring the secure track, so that whether the target object and the corresponding code segment of the target file are modified or replaced can be monitored, and the game plug-in can be prevented from modifying or using the target object by modifying the target file.

[0050] S3, determining the target object based on the secure channel, not updating the target object that does not meet the preset condition, updating the target object that meets the preset condition, and updating and recording the update key point of the target object after the update.

[0051] In the embodiment, the security channel is established between the target object and the target file through the appearance feature and the logic feature corresponding to the target object, so that the interaction between the target object and the target file in the network game can be monitored to determine whether the target object meets the preset condition. Only when the target object meets the preset condition, the target object can be updated or used, so that the game plug-in cannot modify or use the target object by modifying the target file, the game plug-in can be blocked in advance before the target object in the network game transmits data, and the fairness of the network game can be maintained. The appearance feature and the logic feature corresponding to the target object are virtually connected with the corresponding code segment in the target file to form a security track, and the security track is monitored by the plurality of security probes, so that the tampering behavior of the game plug-in on the target object or the target file can be accurately identified.

[0052] As an optional embodiment, the step of determining the target object of the network game based on the target object to determine the target file comprises:

[0053] S11, determining the game ID of the player, determining the target object corresponding to the player in the network game based on the game ID, and the target object is bound to the game ID of the player;

[0054] S12, determining the target file corresponding to the target object according to the target object, and associating the target object with the corresponding target file, wherein the target object corresponds to at least one target file;

[0055] It should be noted that the target object is a game character or a prop of the player in the network game, and the game character and the prop of the player in the network game are bound to the game ID of the player. Each target object corresponds to a local file (such as a network game, an installation package, an update package, a plug-in, etc.) in the game device (such as a computer, etc.) of the player. The part of the file corresponding to the target object in these local files is the target file, and the target file can be used for the use and update of the game character or the prop by the player. Through the association of the target object and the target file and the binding to the game ID of the player, whether the player can use and update the target object can be determined according to the game ID of the player, and the use of the network game plug-in is avoided.

[0056] As an optional embodiment, the step of determining the update key point based on the update key point to establish the security channel between the target object and the target file comprises:

[0057] S21, acquiring the appearance feature and the logic feature corresponding to the target object, and taking the appearance feature and the logic feature corresponding to the target object as the update key point of the target object;

[0058] S22, establish a secure channel between the target object and the target file based on the appearance feature and the logic feature, the secure channel corresponds to a plurality of secure trajectories for monitoring the target object and the target file, and each secure trajectory is deployed with a plurality of security probes for monitoring the secure trajectory;

[0059] As an optional embodiment, the step of obtaining the appearance feature corresponding to the target object comprises:

[0060] extracting the contour, color and size of the target object, i.e. obtaining the appearance feature corresponding to the target object;

[0061] As an optional embodiment, the step of obtaining the logic feature corresponding to the target object comprises:

[0062] S211, obtaining the purchase record of the game ID corresponding to the player of the target object, and associating the target object with the purchase record of the game ID corresponding to the player to obtain behavior association;

[0063] S212, obtaining the permission information of the game ID corresponding to the player of the target object, and associating the target object with the permission information of the game ID corresponding to the player to obtain permission association;

[0064] S213, marking a plurality of code segments with front and back logical dependencies in the target file corresponding to the target object, and associating the target object with the plurality of code segments with front and back logical dependencies to obtain dependency association;

[0065] S214, marking a redundant code segment existing in the target file corresponding to the target object, and associating the redundant code segment with the corresponding target object to obtain disturbance association;

[0066] S215, binding the behavior association, the permission association, the dependency association and the disturbance association to the corresponding target object, i.e. obtaining the logic feature corresponding to the target object;

[0067] It should be noted that the contour includes the contour of the target object (such as the head contour, body contour, and contour of the props of the game character), the color includes the color of the target object (such as the skin color of the game character and the color of the props), the size includes the length, width, and the like of the game character or the props; the behavior association is whether the game ID of the player corresponding to the target object exists a purchase behavior and a recharge behavior, and the permission association is the unlocking and skill upgrading of the game character, and the like. These behavior associations and permission associations are associated or bound with the game ID of the player, so that some game players without purchase or recharge behaviors can be avoided from modifying the target object by using game hacking; the dependence association is that the target object corresponding to the target file has associated code segments before and after the code segment (which can also be a plug-in or the like), the code segment and the associated code segments before and after the code segment form a logical chain and are associated with the target object, so that part of the hacking can be avoided by modifying the code segment of the target file to modify or update the target object; the perturbation association is that the target object corresponding to the target file has redundant code segments (the redundant code segments are additional code segments), the redundant code segments are associated with the target object, and only when the target object receives a hidden function (the hidden function (such as hidden_debug_function) controls the visibility of the code segment by a condition (such as debug_mode), when debug_mode = False, the redundant code segment will be hidden and cannot be detected or modified by hacking, and this mechanism (perturbation association) increases the difficulty of hacking to modify the target file or the target object), the hidden function hides the redundant code segment, so that part of the hacking can be avoided to replace or delete part of the code segment to modify or update the target object; by subsequently establishing a secure channel between the target object and the target file, the secure channel corresponds to a plurality of secure trajectories, and the formation of the secure trajectory is as follows: for example, a secure trajectory corresponding to an appearance feature (such as a contour) is formed between the appearance feature (such as a contour) corresponding to the target object and the target file (such as a code segment corresponding to the contour), and a secure trajectory corresponding to a logical feature (permission association, such as skill unlocking of the game character) is formed between the logical feature (permission association, such as skill unlocking of the game character) corresponding to the target object and the target file (the target file includes a code segment for controlling the skill unlocking of the game character), so that the secure trajectory formed by the appearance feature (such as the contour) and the logical feature (such as the permission association) can prevent the game hacking from modifying the target file, and ensure that the target file has uniqueness, security, and cannot be modified without permission of the server.

[0068] As an optional embodiment, the step of establishing a secure channel between the target object and the target file based on the appearance feature and the logical feature comprises:

[0069] S221, virtually connecting the appearance feature corresponding to the target object and the corresponding code segment in the target file to obtain a secure trajectory corresponding to the appearance feature;

[0070] S222, virtually connecting the logical feature corresponding to the target object and the corresponding code segment in the target file to obtain a security track corresponding to the logical feature, wherein the security tracks corresponding to the several appearance features and the logical feature form a security channel between the target object and the target file;

[0071] S223, deploying several security probes on each security track corresponding to the appearance feature and the logical feature, wherein the several security probes are associated with the corresponding security track;

[0072] S224, monitoring the security track corresponding to the appearance feature and the logical feature based on the several security probes, and binding the obtained monitoring result with the corresponding security channel;

[0073] It should be noted that if the target object is a game character, the appearance feature is the skin color of the game character, and the skin color corresponds to a code segment in the target file. Virtually connecting between the code segment and the skin color obtains the security track of the appearance feature (skin color). Monitoring the security track by the several security probes can obtain whether the security track has modification, transmission anomaly, etc. By establishing a security channel between the target object and the target file based on the appearance feature and the logical feature corresponding to the target object, the interaction between the target object and the target file in the online game can be monitored to determine whether the target object meets the preset condition (interaction includes but is not limited to data transmission). If not, the target object is not updated or used, which can avoid the use of online game plug-ins and avoid the modification or use of the target object by modifying the target file through the game plug-in, so as to maintain the fairness of the online game.

[0074] As an optional embodiment, the step of monitoring the security track corresponding to the appearance feature and the logical feature based on the several security probes and binding the obtained monitoring result with the corresponding security channel comprises:

[0075] S2241, determining a start end port, an end end port and a server front end port of the security track corresponding to the appearance feature and the logical feature, and deploying at least one security probe on the start end port, the end end port and the server front end port, wherein the security probe is used to monitor the state of the start end port, the end end port and the server front end port;

[0076] S2242, monitoring the state of the start end port, the end end port and the server front end port by the several security probes to obtain a monitoring result of the corresponding security track, and binding the monitoring result of the corresponding security track with the corresponding security channel;

[0077] It should be noted that the start end port, the end end port and the state of the server front end of the security trajectory are monitored and recorded by the security probe, and the security probe is equivalent to a RASP probe, an agent probe or a network protocol analyzer (such as Wireshark) and the like; the start end port of the security trajectory is the starting point of the security trajectory, such as the update key point A (skin color) corresponding to the target object, the end end port of the security trajectory is the end point of the security trajectory, such as the code segment (or plug-in) of the target file corresponding to the update key point A of the target object, and the state of the start end port and the end end port, such as the absence and change of the update key point A (skin color); the server front end port of the security trajectory, such as the communication end point (such as the interface or module of the server receiving and processing the request) between the update key point of the target object and the corresponding server when mobilizing the target file, the state of the server front end port, such as the transmission flow corresponding to the update key point of the target object when mobilizing the target file, when the target object or the target file is not modified, the transmission flow corresponding to each mobilization should be the same or change very little, when the transmission flow corresponding to the update key point of the target object when mobilizing the corresponding target file changes greatly, it is considered that this security trajectory may be modified, and the relevant personnel set the change range of the transmission flow (such as 1% to 3% change), which can consider that this security trajectory may be changed when the transmission flow changes greatly, so as to monitor the security trajectory from the transmission flow of the target file; by monitoring the start end port, the end end port and the server front end port of the security trajectory by the security probe, whether the security trajectory is changed can be monitored, if changed, the changed port is transmitted to the security trajectory, the update key point, the security channel and the server through the monitoring security probe, so as to realize the complete monitoring of whether the target object and the target file are modified, and to monitor any non-target file modification of the corresponding target object, avoiding the use of network game plug-in and maintaining the fairness of network game.

[0078] As an optional embodiment: the step of determining the target object based on the security channel, not updating the target object that does not meet the preset condition, updating the target object that meets the preset condition, and updating and recording the update key point of the target object after updating includes:

[0081] S33, updating the update key point of the target object after the target object is updated, recording and uploading the update content corresponding to the target object to the corresponding server;

[0082] It should be noted that the update of the target object herein represents the replacement of the game skin of the target object or the replacement of the game prop; by monitoring the plurality of safety tracks corresponding (bound) to the safety channel, the monitoring results of the safety tracks corresponding to the safety channel can be obtained, which can reflect whether the safety tracks and the corresponding safety channel exist changes and the content of the changes; by comparing the monitoring results with the preset conditions, the preset conditions are the changes (such as code modification, permission change, and change range of transmission flow) of the update key point of the target object or the target file allowed by the server, if the monitoring results are within the changes allowed by the server, it means that the preset conditions are met, that is, the changes of the target object and the target file are made under the conditions allowed by the server, so that the target file can be updated, otherwise, if the monitoring results are not within the changes allowed by the server, it means that the preset conditions are not met, that is, the changes of the target object and the target file are not made under the conditions allowed by the server, so that the target object is not updated, thereby avoiding the modification of the target object by the external hanging of the network game, and ensuring the fairness of the network game; by updating the update key point of the target object, and establishing new safety channels, safety tracks and safety probes between the target object and the target file through the updated update key point, the target object and the target file can be continuously monitored to avoid the modification of the target object or the target file by the external hanging of the network game; by recording and uploading the update content corresponding to the target object to the corresponding server, the server records and stores the update content, so as to long-term monitor the target object and avoid the modification of the target object by the external hanging of the network game.

[0083] As an optional embodiment: when the target file is updated, the target file needs to correspond to the target file record stored in the server;

[0084] It should be noted that in the network game, sometimes the target file needs to be updated, when the target file is updated, the target file record such as purchase record, permission information and version information is bound to the game ID of the player stored in the server, only when the target file corresponds to the target file record, the target file can be updated, thereby avoiding the case that the target file is replaced or modified, after the target file is updated, the safety channel between the target file and the target object is reconstructed, thereby the target object and the target file can be continuously monitored to avoid the use of the network game external hanging, and ensure that the target file has uniqueness, security and cannot be modified under the condition allowed by the server.
