An encapsulation technique for cryptography based on steganography

In cryptography, plain data is transformed into an incomprehensible form. In this paper, we propose an integrated approach to integrated cryptography and steganography for RGB images. A steganography method for concealing secure information using another cover form, such as images, voice, or videos. The Elliptic Curve Cryptography (ECC) encryption method and Pixel-Value Differencing (PVD) method are used here to achieve that extremely high security level. As a result, the robust protection algorithm uses higher bit sizes within the Red, Green, and Blue channels of the cover image, yielding very high-level security levels when transferring the secure information over unsecure communication channels.
