Embodiment Construction

[0029] In order to verify the performance of the algorithm proposed in this paper, an 8-bit grayscale image H with a size of 512×512 is used in the simulation experiment to carry out information carrying transmission and restoration by the method of the present invention.

[0030] Secret information is arbitrary data: images or other data.

[0031] Example:

[0032] For image format data (length in bytes), each pixel is composed of 8 bits to form a byte, or each LSB of 8 bytes forms a byte.

[0033] Select data with the following characteristics or processed data with the following characteristics:

[0034] (1) Dataset 1:

[0035] 000XX000

[0036] 001XX001

[0037] 010XX010

[0038] 011XX011

[0039] 100XX100

[0040] 101XX101

[0041] 110XX110

[0042] 111XX111

[0043] The original data is:

[0044] 00XX0000 is 000XX000 after cyclic shift left by 1 bit

[0045] 01XX0010 is 001XX001 after cyclic shift left by 1 bit

[0046] 10XX0100 is 010XX010 after cyclic shif...

Abstract

The present invention proposes a method for carrying information losslessly in arbitrary byte data, which can carry out carrying (hiding) transmission of information in byte data of any format without changing the amount of data; information can be extracted losslessly and losslessly while carrying concealment Restore carrier data. The lossless information hiding in arbitrary byte data is realized by searching redundant bits in any type of data files according to the byte format, and the information hiding capacity is only related to the structure of the data itself. The typical carrying (hiding) capacity is between 3.75% and 37.5%, which is suitable for carrying (hiding) transmission of various types of data such as raw data transmission systems and compressed data.

Description

technical field [0001] The invention relates to a method for data communication, in particular to a method for embedding information in arbitrary byte data for lossless transmission, and belongs to the field of communication (such as data communication technology, etc.). Background technique [0002] The current society is an information society, and the issue of information security has become an increasingly urgent problem. Information hiding (data hiding) is an important branch of information security. It uses human visual redundancy to embed secret information into the carrier to achieve security. The purpose of transmitting secret information or improving the efficiency of data transmission. [0003] With the development of science and technology, the efficient transmission of image data and the security of transmission have become more and more important. Through information hiding (also called data hiding) technology, secret information can be embedded in the data wi...
