A Novel Information Security Scheme using Cryptic Steganography

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