The LSB steganographic algorithm and its implementation in a GUI application with MATLAB App Designer are described. Computer and digital steganography are considered and an algorithm is implemented that allows one to hide useful information in an image. This application allows users to secretly exchange text messages using images of certain formats. These image formats use lossless compression algorithms. The program provides algorithms that make it difficult to steganalize files by statistical methods. An RSA electronic digital signature algorithm is also implemented, which allows you to confirm the authorship of the user and verify the integrity of the message.
