Binary image steganography method based on disturbance distortion and pixel selection

Abstract

The invention provides a binary image steganography method based on disturbance distortion and pixel selection, which is characterized in that a distortion condition brought about by pixel overturn of a binary image is calculated according to a more appropriate disturbance measurement method, secret information is embedded through STC encoding, the embedding capacity of the secret information is improved, a secret carrying image is acquired, post-processing is performed on the secret carrying image according to a pixel selection strategy, and a binary steganographic image used for channel transmission is acquired. The binary steganographic image acquired according to the invention is higher in visual quality and higher in safety and anti-detection capacity compared with previous methods. The invention further provides a post-processing strategy for pixel selection in consideration of mutual influences existing between turnover pixels, and a safer binary steganographic image with higher visual quality is acquired. The binary image steganography method can be used for the information security and especially for the aspect of binary image secret information transmission.

Description

technical field [0001] The present invention relates to the fields of digital forensics and information security, and more particularly relates to a binary image steganography method based on disturbance distortion and pixel selection. Background technique [0002] With the continuous development of science and technology, the continuous improvement of digital forensics and information hiding technology, input a carrier image, information hiding technology can write secret information in the carrier image, and generate a steganographic image that can be used for public channel transmission , for this technology, it is necessary to find the pixel position of the carrier image that is suitable for embedding information. In this part of the pixel, the secret information is embedded through the steganographic technology, and the obtained steganographic image can be transmitted in the public channel without will be found. Binary images are images with only two values ​​​​"0" and...

AI Technical Summary

Problems solved by technology

[0004] Most of the previous binary image steganography methods cannot find ideal embedding positions, resulting in the generated steganographic binary image with obvious visual distortion, which can even be detected by human eyes.
