A new hybrid security allocation steganography algorithm

Abstract

Security, authentication, and identification are essential requirement for confidential data transmission. The will known methods of data encryption attain certain security levels, they make the encrypted data unreadable and unnatural this attracts some unintended observer attention. To search for a higher security approach, Steganography and Cryptography are two popular ways of sending vital information in a secret way. One hides the existence of the message and the other converts the message into an unreadable format. This paper, describes a method for integrating the advantages of Cryptography and Steganography together through image processing. The paper introduces a New Hybrid Security message Allocation Algorithm (NHSA) to achieve a higher level of security. The statistical evaluation of this system shows that, a higher PSNR and MSE are achieved comparing with the other systems.
