Optimized Block Steganography based Crypt Encryption for Secured Data Transfer

In this paper a new steganographic technique using an advanced cryptographic technique has been proposed. In the encryption part of this paper the concept of ASCII value of the English alphabets have been used. Besides this the binary conversion of those ASCII values and the concept of hamming distance measurement are also used here. Multiple Auxiliary keys are generated using one password and after the encryption, the steganographic part is done with the help of grey-scale concept.
