Encryption processing method for high-performance video coding standard

The present invention discloses a high-performance video coding standard encryption processing method, the method comprising: an instruction input by the user according to the encryption, it is determined whether the current video frame using a region of interest (ROI) encryption; if yes, using the tracking detection algorithm (TLD ) calculated from the encoded video frame, the current ROI areas of the video frame, with restrictive and restrictive motion search mode is selected, and the syntax element to be encrypted in the ROI proposed and / or discrete DC coefficients cosine transform DCT is performed disorder encrypted, complete ROI is encrypted; otherwise, the DC coefficient to be encrypted syntax elements of the current video frame is raised and / or a discrete cosine transform DCT is performed disorder encryption processing, completion of the whole frame encryption . It achieved full frame encryption encryption and high-performance video ROI area by using the method disclosed in the present invention.
