Abstract

The invention relates to the technical field of information hiding and detection. A digital steganography and steganalysis method for a color image is characterized in that a secret information embedding step comprises the following small steps: generating a general image data buffer and data steganography factors; performing a series of function transformations on the color image and the data steganography factors to generate a steganography data-contained color image. A secret information extracting step comprises the following small steps: generating the general image data buffer, and performing a series of function transformations on the steganography data-contained color image to read out steganography data. According to the digital steganography and steganalysis method for the color image disclosed by the invention, by solidifying the steganography data, the steganography speed is increased, and the data steganography CPU (central processing unit) time and the steganography data reading CPU time are shortened. The digital steganography and steganalysis method for the color image supports various color image formats. By adopting the thread pool technique, the data steganography concurrence number is improved, and the robustness of data of preventing steganography attack is enhanced.

Description

technical field [0001] The invention relates to the technical field of information hiding and detection, in particular to a color image digital steganography and an analysis method thereof. Background technique [0002] With the rapid development of computer technology, information processing technology and network communication technology, human beings have entered an unprecedented digital information age. In particular, the popularity of the Internet has brought about many changes in people's thinking, work, and lifestyle. People are more and more inclined to obtain all kinds of information through the convenient and fast network. E-commerce, e-government, network office, etc. have become indispensable working methods for the efficient operation of society. Email, Internet chat, BBS, etc. Way. While the network brings convenience to people, it also brings challenges in information security: whether documents related to national security and government secrets can be safe...
