The present application relates to a cheating determination method, device, storage medium and computer equipment, the method comprising: acquiring a video frame formed during the game; extracting the pixel value of the target color from the video frame to obtain the A frame image composed of pixel values; according to the frame image, it is determined that the video frame contains a virtual object displayed due to a perspective obstacle; when it is detected that the sight for positioning the virtual object is turned on, the displayed Among the virtual objects, it is determined that there is at least one virtual object in the field of view area corresponding to the aimer; when it is detected that the projection operation is performed, it is determined that there is cheating during the game. The scheme provided by this application can improve the efficiency of judging cheating behavior.

The present invention provides a method, device, electronic device, and storage medium for training a cheat recognition model. The method includes: determining the training samples of the cheat recognition model based on the behavior information of the target user, and determining the characteristics of the cheat portrait in the cheat recognition environment. ; According to the behavior information of the target user, determine the corresponding behavior sequence information; determine the model parameters that are compatible with the plug-in identification model, so that the behavior of the target user can be monitored in real time through the plug-in identification model, and According to the risk prediction results, the matching event execution strategy is executed, which makes the generalization ability and data processing ability of the cheat recognition model stronger, adapts to different cheat recognition environments, and reduces the robustness of the cheat recognition model. At the same time, there is no need to obtain a large number of labeled samples to train a model dedicated to identifying cheating behaviors, so the cost of identifying cheating behaviors can be effectively reduced.

The invention discloses an intelligent billiards referee anti-cheating method and system, comprising: acquiring the batter's batting parameters, and calculating the batting energy value according to the batting parameters; after the batter finishes hitting the ball, acquiring Continuous frame images of the table and billiards on the table; analyzing the continuous frame images to obtain the movement trajectory of each billiard ball; obtaining the corresponding energy loss value of each billiard ball according to the movement trajectory of each billiard ball; calculating the energy consumption of all billiard balls value, judging whether the sum of the energy loss values ​​is greater than the energy value of hitting the ball, and if it is determined that the sum of the energy loss values ​​is greater than the energy value of hitting the ball, it indicates that there is cheating. According to the relationship between the energy value of hitting the ball and the energy loss value of the billiard ball after hitting the ball, it is accurately judged whether the player is cheating.

The invention discloses a method, an apparatus and a system for preventing cheat during step count. The method comprises the following steps: acquiring amount of steps collected by accumulation of a step counting sensor in an intelligent wearable device; counting collected step number at every preset time interval, calculating difference values between adjacent two counted step numbers, and obtaining a step increment in each preset time interval; determining whether step counting is suspected to be cheated according to the step increment in each preset time interval, if step counting is suspected to be cheated, acquiring heart rate data collected by a heart rate sensor in the intelligent wearable device, and confirming whether the step counting is really cheated according to heart rate data. The method fills the blank for preventing users cheating in the aspect of step count in the prior art, provides a real sports rank; prevents deviation appeared in evaluation of user health state due to step count data errors; and prevents improper incomes obtained by cheating in step count matches which causes losing match meanings.

A cheating detection method, device and terminal including: determining the data to be detected, and select the observation index to be observed as well as a variety of dimensions, each dimension has to be observed at least one value; According to the plurality of dimensions to be observed, the values of each dimension to be observed are combined to form a plurality of observation dimension combinations; According to the data to be tested, the index value of the observed index is calculated for each observation dimension combination; The candidate anomaly combination in the observation dimension combination is determined according to the index value; Based on the historical data, the candidate anomaly combination is analyzed to determine the abnormal combination in the candidate anomaly combination.The abnormal combination is used to determine the flow of cheating. The technical scheme of the invention can detect the flow of cheating.

The invention relates to the field of network education technology, and particularly to an intelligent cheating preventing method and a device thereof, wherein the method comprises the steps of acquiring position distribution of intelligent devices by a server, and further determining n intelligent devices with a cheating risk around a random intelligent device A; distributing examination questions to each intelligent device by a server according to different sequences so that each intelligent device successively displays the problems according to a distributed sequence; and dynamically adjusting the displaying sequence of the questions on each intelligent device by the server based on the question answering progress of each examinee, so that the current displaying questions on a random intelligent device in the n intelligent devices and the intelligent device A are different. According to the method and the device, not only can the examination questions be distributed to the intelligent devices according to different sequences in advance, but also the question sequence is dynamically adjusted according to the question answering progress in an examination process so that displayingof the same question on the screens of adjacent examinees at the same time is prevented, thereby reducing cheating behaviors.

The invention discloses a reading cheating behavior identification method, computing equipment and computer storage medium. Wherein, the method includes: for any sampling unit, acquiring the attribute information of multiple page turning behaviors contained in the sampling unit; according to the attribute information of the multiple page turning behaviors contained in the sampling unit, calculating the corresponding page turning behavior of the sampling unit Behavior difference degree; if the difference degree of page-turning behavior corresponding to the sampling unit is less than a preset threshold, it is determined that the reading behavior corresponding to the sampling unit is a cheating behavior. This scheme can accurately identify reading cheating based on page-turning behavior, thus providing a basis for the prevention and control of reading cheating. Moreover, the implementation process of this scheme is simple and easy, the identification efficiency is high, and it is suitable for large-scale application and implementation.

The invention provides a method and device for identifying machine assisted cheating. The method includes the following steps that: a time interval sequence is generated according to the operation time of an assessed device or account; the time interval sequence is discretized, so that a discrete time interval sequence can be formed; the entropy rate of the discrete time interval sequence is calculated; and when the entropy rate is smaller than a preset threshold value, it is identified that the assessed device or account adopts machine assisted cheating in operation. According to the method and device of the invention, the entropy rate of the discrete time interval sequence is calculated, so that rhythmic operation and arrhythmic operation can be accurately distinguished, and therefore, the machine assisted cheating can be accurately identified.
