Abstract: The exploration work is regarding the learning of cryptographic and steganography techniques and make available the advancement in security with the amalgamation of these procedures by the side of with the hashing techniques such as MD5 hash method has been worn out for offering the secrecy of information over the network. The communication of information necessitates being secured over the network. This paper projected the multiple coatings approach for security of data which comprises the hashing, cryptographic steps and steganography procedures for encryption and hiding of data. For supplementary security, the LSB technique has been regarded with audio file for hiding of encrypted data. The result has been generated with the MATLAB 2010 version.
