A secure image steganography method and electronic device based on style transfer

Abstract

The invention discloses a style conversion-based secure image steganography method and electronic device. A secret information, a content picture and a style picture are input into a first convolution network to generate a secret picture. The invention directly uses the neural network technology to generate the secret image, hides the corresponding relationship between the carrier image and the secret image, and hides the secret information directly into the style texture, thereby realizing the safe transmission of the secret information; overcoming the limitation on the size of the carrier image, Increase the generality of the method.

Description

technical field [0001] The invention relates to the technical field of information security, and in particular, to a style-transfer-based secure image steganography method and electronic device. Background technique [0002] Steganography, as an important branch in the field of information hiding, can achieve the purpose of covert communication by embedding secret messages into multimedia files (such as digital images, audio, video, text, etc.). The multimedia files before and after steganography are visually and statistically indistinguishable, and thus do not raise suspicions for attackers. With the development of digital technology, image information has become more and more abundant in the Internet, and the secret information transmitted through images is not easy to arouse the alert of the other party. Moreover, due to the advantages of abundant data and widespread application, images have gradually become a popular secret communication carrier. [0003] Traditional im...

Problems solved by technology

However, these methods have the problems of poor imperceptibility and small steganographic capacity, and the performance indicators need to be further improved.

[0005] In general, although the existing information steganography methods have achieved high data transmission security, in image steganography, secret information is hidden by modifying some specific pixels or coefficients of the carrier image, resulting in pixels or The correlation between the coefficients changes, there is a risk of being detected by the steganographic detection algorithm

However, the mainstream steganalysis algorithm uses the classifier trained by the secret image and the corresponding carrier image to identify the embedded information, so the steganographic generation method still has a great security risk, and the security needs to be further improved.
