Real-time video sensitive information protection system and method

Abstract

The invention provides a real-time video sensitive information protection system and method. The real-time video sensitive information protection method comprises the following steps: S1, collecting a real-time video stream; S2, separating the video stream, separating the video stream by an equal interval, adopting a detection algorithm to extract a preset foreground stream in each segment of video stream, and hiding privacy and sensitive information in the foreground stream through a reversible algorithm, wherein the reversible algorithm refers to a public key generated in a corresponding time interval, the detection algorithm comprises target detection and template matching algorithms, the reversible algorithm comprises a scrambling algorithm and a password book translation algorithm, and a scrambling algorithm performs data encryption through image splitting, data expansion and image combination; S3, adopting an irreversible algorithm to erase sensitive information in the video stream so as to obtain a background stream, wherein the irreversible algorithm comprises a mosaic method, a color block covering method and a frosted glass effect; and S4, restoring the original video stream. The encryption degree of the video stream can be improved, encryption is reversible, and the protection degree of personal privacy is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of data privacy protection, and in particular relates to a real-time video sensitive information protection system and a method thereof. Background technique [0002] With more and more cameras, information such as human faces and human bodies will inevitably be captured in real-time videos, but these are all sensitive information. In the usual road monitoring, elevator monitoring, back kitchen monitoring and other scenarios, in order to protect personal privacy, privacy protection operations should be performed in real-time images. When an abnormal situation occurs, the original video is retrieved and used as evidence. [0003] In the prior art, sensitive information such as human faces, human bodies, and windows in videos captured by cameras need to be blurred to prevent leakage of sensitive information. For example, the patent publication No. CN111654664A discloses a high-altitude parabolic detection me...

Problems solved by technology

Although it plays a certain role in privacy protection, when the video is leaked, it is very easy for technicians to analyze the blurring method of the video and find an inverse calculation method to crack all the videos processed by the blurring method, resulting in the leakage of sensitive information and threatening The video files stored in the entire system, and the above-mentioned patent does not provide a method to obtain the original information, the video perception is poor
