Text information hiding method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a text information hiding method and device, electronic equipment and a storage medium. The method comprises the steps of inserting a to-be-hidden text into any one of M+1 positions determined by M second characters in a preset random character set to obtain M+1 text character strings; for each text character string, exchanging the position of each character in the text character string with other characters, and for each character, calculating the difference value between the character distance between the characters before and after the character exchange position and the character distance of the corresponding characters in the to-be-hidden text; for each character of each text character string, according to the difference value between the character distance between the characters before and after the character exchange position and the character distance of the corresponding characters in the to-be-hidden text, conducting calculating to obtain the comprehensive difference value of different text character sets obtained before and after the character exchange position; and taking one or more of the text character sets corresponding to the comprehensive difference values meeting the preset requirements as a target character set.

Description

technical field [0001] The present application relates to the technical field of information security, and in particular, the present application relates to a text information hiding method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] At present, the requirements for information security are getting higher and higher, and the means of protecting information security are becoming more and more abundant. Many encryption and decryption methods of text information have been made public. In some special cases, it is not suitable to encrypt text information or as an auxiliary means of encryption, and text hiding is often used. [0003] The basic principle of text hiding is to store the text information that needs to be protected in a large number of text information that has similar characteristics but does not need to be protected, so that it is not easy for information thieves to obtain the protected text information by analy...

[0003] The basic principle of text hiding is to store the text information that needs to be protected in a large number of text information that has similar characteristics but does not need to be protected, so that it is not easy for information thieves to obtain the protected text information by analyzing the probability characteristics of the text

The existing text hiding methods mainly use the normal text data collected from the Internet as a text library to hide, and the text to be hidden is easier to find
