An investigation into image hiding steganography with digital signature framework

Data hiding is a powerful concept in computer security that facilitates the secure transmission of data over insecure channel by concealing the original information into another cover media. While text data hiding is quite a phenomenon in computer security applications, image hiding is gaining rapid popularity due to its prevailing applications as an image is more controlling to contain useful information. In this paper, we have carefully investigated the concept of steganography by incorporating image hiding within another image with a secure structural digital signature framework. Our proposed work includes the initial image preprocessing tasks through filtering of the host image followed by embedding of the secret image and description of the image data within the host image. Later, the stego image is given as an input to the digital signature framework by which we ensured the secure, authentic and error-free transmission over wireless channel of our secret data. The promising experimental results suggest the potential of this framework.
