Abstract
ABSTRACTIn this paper we proposed a method for image steganography in which the cover image represented using a pseudo hexagonal structure is used for hiding the secret image. As we know, the conventional method of representing a digital image is using square-shaped pixels. Using hexagonal-shaped pixels to represent a digital image is a new approach because of its various advantages like symmetry, higher angular resolution, consistent connectivity, and higher sampling efficiency. This paper describes a method for hiding an image using a pseudo hexagonal structure cover image. In this method the conventional square pixel secret image is embedded in a cover image with pseudo hexagonal structure. Using this method we can hide an image by preserving its quality and the experimental results show that the mean square error between the secret image and the image retrieved from the stego image is zero.
