Reversible steganographic method of hiding information based on image interpolation

When information is exchanged through open communication networks, there is a possibility of third-party interception. Various methods of data protection have been developed and applied to eliminate this flaw. In this work, a task of developing a new reversible steganographic method of concealing information based on interpolation of an image is set and solved. The developed algorithm has a higher payload of secret information while preserving the high visual quality of the stego image. Results of the pilot studies confirm this and are presented in this article.
