An Information Hiding System Based on Image Steganography for Color Images

Abstract: Information Hiding is one of the challenging issues in the field of security. Steganography is one of the most important fields in information hiding system. Steganography is used to hide the existence of secret message by embedding the message inside any cover object like image, text, audio and video files. This paper proposes a new method based on modified PVD method in order to obtain larger embedding capacity and produce acceptable stego image quality. To prove the better performance of the proposed method, the comparison analysis is performed according to Peak Signal to Noise Ratio (PSNR) values and embedding capacity. Experimental results show that the proposed method provides an average hiding capacity gain of 1.85 times over the existing method while maintaining acceptable of stego image quality.
