Secure multimedia data transfer using crypto and stegano algorithms

Abstract

Recent developments in Steganalysis have made it difficult to secure personal content, messages, or digital images using steganography. Using Steganalysis can easily reveal the presence of hidden information in storage files. This paper presents a new Steganographic approach to communication between two individuals. The approach presented in this paper uses both Steganographic and cryptographic methods. Cryptography uses Rivest–Shamir–Adleman (RSA) and Steganography use image Steganography to hide data. It also uses the mutual authentication process to satisfy all services in the field of cryptography, i.e., access control, confidentiality, integrity, and authentication. In this way, it can store data more securely. Since it uses the RSA algorithm to protect the data again, it performs Steganography to hide the data in the image. Thus, any other person on the network cannot access the data present on the network. Only the sender and receiver can extract the message from the data.
