A Review on Implementation of Cryptographic Method for Secure Audio Data Hiding in Digital Images

Information security is a major obstacle in different areas like military, network application, are illegally access the information. So, it is very important to hide the secret data efficiently. By means of cryptography we can hide information to be transmitted over network. The cryptography makes the secret message not understood unless the decryption key is available. In this project a symmetric key is introduced which provides secret arrangement of secret signal data bits in cover signal data bits. The encryption process is performed on secret audio signal. File is forwarded from one location to another location in the network. The algorithm used for file encryption provides more security. Cryptography along with the steganography provides perfect security.
