Abstract:
Steganography is the art and science of hidinginformation. The goal of steganography is to avoid drawingsuspicion to the transmission of a hidden message. Thesuccess of steganography depends on the secrecy of the covercarrier. Once the steganographic carrier is disclosed then thesecurity depends on the robustness of the algorithm and thecryptographic methods used. Therefore, to maintain secrecyeither we need to make the carrier more robust againststeganalysis or discover new and better carriers. This paperdiscusses a new steganography technique for palette basedimages. Secret message is encrypted using public keycryptography before hiding. The bits of encrypted messagewill be hidden inside the stretched palette of image.
