HIDING AN IMAGE INSIDE ANOTHER IMAGE USING VARIABLE-RATE STEGANOGRAPHY
Journal Title: International Journal of Advanced Computer Science & Applications - Year 2013, Vol 4, Issue 10
Abstract
A new algorithm is presented for hiding a secret image in the least significant bits of a cover image. The images used may be color or grayscale images. The number of bits used for hiding changes according to pixel neighborhood information of the cover image. The exclusive-or (XOR) of a pixel’s neighbors is used to determine the smoothness of the neighborhood. A higher XOR value indicates less smoothness and leads to using more bits for hiding without causing noticeable degradation to the cover image. Experimental results are presented to show that the algorithm generally hides images without significant changes to the cover image, where the results are sensitive to the smoothness of the cover image.
