Description

Non-additive steganography method for enhancing JPEG image block boundary continuity
Technical Field
The invention relates to the technical field of steganography, in particular to a non-additive steganography method for enhancing the continuity of JPEG image block boundaries.
Background
Steganography is a technology of covert communication, and aims to realize covert communication by using digital multimedia (such as images) as a carrier to cover secret information. At present, the mainstream adaptive steganography technology is to reasonably define an additive distortion function based on image texture and further utilize a minimized distortion steganography code STC to achieve high security. However, due to the correlation between natural image elements, non-additive distortion functions are more suitable for steganography requirements. At present, a principle of defining non-additive distortion is provided for each of spatial domain images and DCT domain images, the first principle is independently proposed by Li et al and Denmark et al, and the principle is called as a direction consistency principle (SMD), which indicates that the anti-detection performance of adjacent pixels in the homodromous modification in the steganography process is higher. However, the principle is not applicable to JPEG images, and as JPEG images become mainstream media of social networks, requirements for steganography of JPEG images are more and more vigorous, and then Li et al propose a "block boundary consistency principle (BBC)" for JPEG images by studying the correlation of coefficients at the same position of adjacent DCT blocks, wherein the purpose of the principle is to improve the anti-detection performance by maintaining the continuity of space block boundaries in the steganography process.
Although the BBC principle has some effect, Li et al only consider the influence of DCT coefficients at the same position in adjacent blocks on the boundary of a spatial block, which is not sufficient, because changing one DCT coefficient may affect 64 pixels, and a plurality of DCT coefficients may be changed in the same block during steganography, and thus, the anti-detection performance still needs to be improved.
