Abstract

In modern communication, security, privacy, and integrity of the secret data being transmitted is the most important issue and steganographic techniques help in accomplishing this task. In this paper, we have proposed a data hiding scheme using steganography and cryptography in spatial domain. RGB 24 bit bitmap image carries the secret DES encrypted message that is embedded by utilizing the different pixel intensities of the cover RGB image. At receiver side, message is received and message is extracted by applying the reverse of embedding process. The proposed system results in high embedding capacity and also successfully resists statistical attacks like RS analysis, histogram analysis, and chi-square analysis.
