Summary:Today, data and communication security have become challenging issues. Since in cryptography, encrypted messages are available to eavesdroppers, security is the subject of concern and the need for steganography and hiding the information has been raised. In this paper, by integrating cryptography and Steganography, a new scheme is proposed to enhance the data security. In encryption section, the CBC (Cipher Block Chaining) mode of operation is used, and in steganography section, we use graph coloring problem and the correlation of pixel blocks in LSB (Least Significant Bit) method. This helps to increase the capacity and security of steganography. The analysis of the quality functions shows that, in this method, the PSNR (Peak Signal-to-Noise Ratio) increases more than other methods.KEYWORDSCryptography, Steganography, Correlation of Pixel Blocks, Graph coloring,
