Spread-Spectrum (SS) Steganography is attracting increasing interest among researchers and practitioners in the fields of authentication and covert communications. Steganography is the technique for hiding secret information in other data such as still, multimedia images, text, and audio. Whereas Steganalysis is the reverse technique in which detection of the secret information is done in the stego image. Digital data embedding in digital media is an information technology field of rapidly growing commercial as well as national security interest. It considers the problem of extracting blindly data embedded over a wide band in a spectrum domain of a digital medium. To develop a novel embedding and extracting algorithm to demonstrate this problem. Least Significant Bit (LSB) algorithm is used to embed the secret message into the image. Special Cryptography algorithm called triple Data Encryption Standard (DES) is used to encrypt and decrypt the secret message for strengthens the security of this process.
