AI Technical Summary

Problems solved by technology

Since the ability of this method to resist RS analysis depends on the selection of the ratio of pixel value plus or minus 1, if the selection is inappropriate, this method may not be able to effectively resist the attack of RS analysis method

Embodiment Construction

[0016] 1. Principle of RS analysis method

[0017] Literature [3] gives the principle of RS analysis method. Assume that the pixel values ​​in the carrier image belong to a set V. For example, for an 8-bit grayscale image, V={0, 1, Λ, 255}. Use the description function f to examine the image spatial correlation, f represents a real number f(v 1 ,Λ,v n ) and a pixel group G=(v 1 ,Λ,v n ) between the corresponding relationship. For example: use

[0018] f ( v 1 , v 2 , Λ , v n ) = Σ i = 1 n - 1 | v i + 1 - ...

Abstract

An information-hiding method of anti-statistic analysis image based on chaos system includes selecting embedded-position by random sequence generated on basis of chaos system first then carrying out LSB random-embedding and carrying out dynamic compensation on embedded image.

Description

technical field [0001] The invention belongs to the technical field of communication and information security, in particular to a method for hiding image information against statistical analysis based on a chaotic system. Background technique [0002] Information hiding is one of the important research topics in the field of information security. It achieves the purpose of secret communication by embedding information into images, videos, sounds or other digital media for transmission. Among many image information hiding methods, LSB (Least Significant Bits, least significant bit) hiding is widely used due to its advantages of good concealment, large amount of information hiding and easy implementation. Many public information hiding software such as: S-Tools, EZStego and Steganos, etc. have adopted this method. [0003] In recent years, some analysis methods for LSB concealment in image spatial domain have emerged, which can accurately determine whether the image contains ...
