摘要:The demand for effective information security schemes is increasing day by day with the exponential growth of Internet. Cryptography and Steganography are the two popular techniques for secret communication. The contents of message are kept secret in cryptography, where as in steganography the message is embedded into the cover image (text, video and image (pay load)). In this proposed system we developed a system in which cryptography and steganography are used as integrated part along with newly developed enhanced security model. In cryptography we are using MD-5 Algorithm to encrypt a message and a part of message is hidden in DCT of an image, remaining part of the message is used to generate three ( 3 ) secret keys which make the system highly secured. To avoid the problem of unauthorized data access steganography along with cryptography called as Cryptic-Steganography scheme is the right most solution.
