More technical applications are to trace the leaker through some digital watermarking (clear watermarking, invisible watermarking) technical means, but it is irreversible for the secret-related incidents that have occurred. Existing technical means can prevent the confidential information of the display device from being There are obvious deficiencies in the shooting problem

Embodiment Construction
[0017] Combine below Figure 1 to Figure 4 , the present invention is described in further detail.
[0018] refer to figure 1 , the invention discloses a behavior detection method based on target recognition, comprising the following steps: A, analyzing the main target and associated targets in the behavior to be detected; B, taking images or videos of the area to be monitored; C, performing image or video Identifying the main target and the associated target to obtain the position and probability information of the main target and the associated target; D. Correct the probability of the main target according to the position and probability information of the associated target to obtain the occurrence probability of the behavior to be detected. Behavior analysis and detection has always been a relatively difficult point. Here, behavior detection is achieved by analyzing the main targets and associated targets related to the behavior, and then recognizing the target. At presen...

The invention particularly relates to a photographing behavior detection method. The method comprises the following steps: S100, photographing an image or a video of a to-be-monitored area; S200, performing camera and associated target identification on the image or video of the to-be-monitored area to obtain the probability that the camera appears in the image or video and the probability that the associated target appears in the image or video; and S300, calculating the probability of the candid shooting phenomenon in the image or the video according to the formula in which the minimum value is taken, and the influence factor is obtained through calculation. Target recognition is carried out on the camera and the associated target to obtain the probability of occurrence of the target, then the probability of occurrence of the candid shooting phenomenon is calculated according to the probability value, implementation is very convenient, when target recognition is carried out, an accurate frame does not need to be obtained, the probability value does not need to be very accurate, and after correction is carried out through an influence factor, the identification accuracy of the candid photographing phenomenon can be improved, the misjudgment rate can be reduced, and the real-time performance and the accuracy are effectively improved.
Description
technical field [0001] The invention relates to the technical field of information security, in particular to a method and system for detecting video recording behavior. Background technique [0002] Under the trend of information development, the convenience of electronic processing has been recognized by more and more private enterprises, public institutions, and state-owned enterprises. It not only improves office efficiency, but also provides an efficient entrance for future operations such as maintenance inquiries. For the control and confidentiality of confidential documents under some secret-related units, traditional network security companies mainly manage and control through physical isolation and multiple authentication. For example, restrict network transmission and U disk and other transmission media transmission for confidential files in computers. [0003] With the rapid development of software and hardware in the security industry, electronic devices with ca...
