Adaptive Hiding Algorithm Based on Mapping Database
Keywords:Information hiding, Hash function, message digest 5 (MD5), Database, stego-systems.
Information hiding one of the important field of security which provide secure level for the information. Achieving multi levels of security system often researchers used cryptography side by side with steganography. Utilizing message digest algorithm to play the role of crypto which is extracted from secret created database. Message digest algorithm (MD5) used two times as one-way function to provide data integrity. The implemented system evaluated based on peak signal to noise ratio (PSNR) metric and the best value reaches 62.46. the proposed system works in adaptive behavior due to the different use of images as well as the selected point could be used to generate the hash code as well. The implemented system reaches up to sufficient level of security through using both steganography and cryptography.
