Abstract

The invention discloses a dependency maintaining lossless video encryption compression transmission method based on ranking permutation, and relates to the field of video secure transmission. The method comprises the following steps that original video frame sequences from an information source are received and stored in sequence; the ranking permutation sequence of a current video frame in the original video frame sequences is calculated; permutation is carried out on the current video frame by utilizing the ranking permutation sequence of the current video frame in the original video frame sequences to obtain the current permutated video frame; compressing is carried out on the current permutated video frame through a lossless video image compressing standard M-JPEG-LS video image encoder to obtain an encryption compression video frame used for transmission. According to the method, video image compression is combined with video image encryption, and a novel technical approach is provided for video encryption and compression.

Description

technical field [0001] The invention relates to the field of secure video transmission, in particular to a correlation-preserving lossless video encryption and compression transmission method based on sorting and permutation. Background technique [0002] Video generally refers to various technologies that capture, record, process, store, transmit, and reproduce a series of still images in the form of electrical signals. Since video contains redundancy in space and time, uncompressed video transmission is not optimistic in terms of transmission efficiency. Compression efficiency directly depends on the redundancy of the source data, the more related the data, the better the compressibility, and vice versa. Strong encryption, on the other hand, is a process of making random data. In existing video encryption applications, there are problems such as incompatible codec standards, incompatible data formats, low encryption compression efficiency, and security. Therefore, it is...
