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

Abstract

Embodiments of the present application provide a text information hiding method, device, electronic equipment, and storage medium. The method includes: inserting the text to be hidden into any of the M+1 positions determined by M second characters in a preset random character set to obtain M+1 kinds of text strings; for each text character String, exchange each character in the text string with other characters, and for each character, calculate the difference between the character distance between the character before and after the character exchange position and the character distance of the corresponding character in the text to be hidden ; For each character of each text string, according to the difference between the character distance between the characters before and after the character exchange position and the character distance of the corresponding character in the text to be hidden, calculate the different values ​​obtained before and after the character exchange position The comprehensive difference value of the text character set; one or more text character sets corresponding to the comprehensive difference value meeting the preset requirements are used as the 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...

Problems solved by technology

[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
