Abstract: Information security is one of the most exigent problems in today’s technological world. In order to secure the transmission of secret data over the public network (INTERNET) various schemes have been presented to the last decennium. Stenography combined with cryptography, can be one of the best choices for solving this problem. This paper advance a new steganographic method based on the gray-level modification for true color images using image reciprocity, secret key and cryptography.
