A New Approach of Dynamic Encryption using Steganography

This paper proposes to concentrate on the security of the image information or data. The objective of proposed work is to secure or protect confidential information which is traveling over network by using the cryptography concept. To fulfill the objective of the proposed work we have proposed a new encryption algorithm by analyzing the principle of the encryption algorithm based on the combination of symmetric and steganography. The performance and security of the proposed algorithm is also evaluated. Presented results show the effectiveness of the proposed work, and the combination of these two techniques symmetric and steganography show large variation in key space and provides high-level security. The cipher image generated by this method can be approximately less in size as the original and is suitable for practical use in the secure transmission of confidential information over the Internet.
