Software Implementation of Modified LSB Algorithm with Shamir`s Secret Sharing

Abstract

Today, it is often necessary to transmit a confidential message of a small volume, while the use of complex cryptographic systems is difficult for some reasons. One of these reasons is the impossibility of using reliable products, which, as a rule, are commercial and unavailable to the average computer user. In modern information society, many services are provided with the help of computer networks and information technologies. Information presented in digital form must be reliably protected from many threats: unauthorized access and use, destruction, forgery, leakage, violation of license agreements, disclaimer of authorship, etc. Information protection is extremely important in both commercial and government spheres. The issues of developing effective methods of protecting digital information, in particular methods of computer steganography and steganalysis, are relevant and important for the state and society. To achieve the goal, it is necessary to propose a method of increasing stego-resistance, determine the effectiveness of the created solution and analyze the obtained results. The object of research is the process of protecting information embedded in a graphic econtainer. The subject of research is methods and algorithms of computer steganography and steganalysis for images. The research methods used in this work are based on steganographic algorithms.
