Abstract

This application relates to an information hiding method and device. The method includes: acquiring an image to be hidden and a carrier audio; extracting sub-audios whose number is a first value from the carrier audio, the length of the sub-audio matches the size of the image to be hidden; The hidden image and the sub-audio of the first value are input into the information hiding model component, and the secret-carrying audio is output through the information hiding model component. By using the information hiding method and device provided by each embodiment of the present application, it is possible to use audio as a carrier to hide information in the audio. In a specific embodiment, the image steganography is realized by hiding the multi-level residual information of the image into different sub-audio. This method can not only control the amount of image information steganography conveniently, but also make the image information Hiding is more efficient.

Description

Information hiding method and device technical field [0001] This application relates to the technical field of information security, and in particular, to a method and device for hiding information. Background technique With the continuous development of digital media technology and computer networks, people's awareness of information security is becoming more and more Strong, how to ensure the safe transmission of data has begun to attract widespread attention. as a more advanced and efficient data Security protection technology, information steganography has become an important research topic in the field of information security. Many previous researchers have Focus on hiding binary sequences into images or audio, or images into other images, and express A nice hidden effect. With the advent of the era of big data, data forms have become more and more diverse, such as graphs image, video, audio, etc., therefore, encrypted data and carrier data are also becomin...
