Anti-counterfeiting encryption method based on video stream

Abstract

The invention relates to an anti-counterfeiting encryption method based on a video stream. The anti-counterfeiting encryption method comprises the following steps: pre-training a character recognition model; transcoding and slicing the original video stream of the camera; accessing the processed video stream, reading information of each picture in the video stream, putting the picture information into a character recognition model, and recognizing the picture with a character through the character recognition model to find a corresponding slice; carrying out file header byte marking processing on the corresponding slices by adopting random codes; and encrypting the slices according to a byte encryption algorithm corresponding to the random code, so that each slice with the character mark is encrypted by adopting different encryption algorithms. The method has the advantages of being high in safety, small in performance occupation and high in encryption and decryption speed.

Description

technical field [0001] The invention relates to an anti-counterfeit encryption method based on video stream, in particular to a real-time encryption method for monitoring video. Background technique [0002] In the prior art, video files are usually encrypted and decrypted through an encryption algorithm, but there is no encryption and decryption for video streams. Moreover, encrypting and decrypting the entire video stream is too time-consuming and performance-intensive. Due to the sensitivity and confidentiality of video surveillance content, it is necessary to ensure the security and accuracy of video content, but the security of remote transmission in existing surveillance systems is low, and video data is easily stolen and tampered with during network transmission. cause information leakage. Contents of the invention [0003] The purpose of the present invention is to provide an anti-counterfeit encryption method based on video streams, so as to solve the problems r...
