A Novel Dual Encryption Algorithm to Enhance the Security in Image Transmission Using LSB 3-2-2 Technique

Abstract

Nowaday’s providing the security for image is essential for correspondence. Steganography and cryptography are a technical method for the transfer of information to eliminate burglary and stealing of information. Cryptography steganography hides the occurrence of a mystery message. We need more Secured and confidential images to transfer. Steganography procedure on RGB genuine nature utilizing LSB 3-3-2 technique. On the RED & GREEN line, on the LSB Three-Three-two is a procedure, while on the blue channel, it is just 2 LSB. Messages are not exactly RED and GREEN on BLUE platforms. Double encryption techniques are used, such as Caesar cipher & Vigenere cipher, to preserve the nature of the stegno photos and to increase message safety. Use of steganographic strategies are insufficient to give security to informing it is imperative to join the strategy of cryptography. A combination of Caesar Encryption and Vigenere applies to message until they are inserted in LSB Three-Three-Two methods to provide extra protection. At this point we are providing the Caesar code and Vigenere image estimating to enhance security. The target of this is to upgrade the secrecy & security of the image steganography. It will be more efficient because using the two fold layer of security.
