Ensuring the Data Integrity in Infocommunication Systems

Abstract

The article is devoted to the study of the perspectives of steganography to ensure integrity. The definition of information integrity is presented, which meets the new requirements and the definition of cybersecurity. Integrity is achieved through the control and recovery of information. The article provides a detailed analysis of existing approaches to the construction of modern steganometric systems. The greatest attention in the article was paid to the method of hiding information in graphic containers. The proposed method is a modification of the well-known method of replacing the least significant bits. The main difference from the known method is that not all least significant bits are changed. The selection of the bits to be changed is carried out using a pseudo-random sequence generator, while, thanks to the proposed algorithm, no more than 3.12 percent of the bits are changed, which is the limit of visibility for the steganalyst. There are 6.25 percent of information bits in such a message.
