The data security in the digital communication is the major issue in this technological era. There are lots of methods and protocols used for secure communication, steganography is one of them. In this paper, we present the χ Secure Crypto-Stego System for secure communication. A common 256 bits random key is used at the encryption and embedding phase. The entropy and joint image histograms are used for the evaluation of security measure for the method. Experiments were performed with different embedding rate in the selected cover data set of images. The results that we achieved, are the proof of the fact that the proposed scheme is a good contribution in the scientific community in the field of Information hiding.
