With the advancement in the field of communication technology, secure multimedia transmission has become an integral part of it. The strong correlations among the bits, pixels and blocks in a given arrangement of an image form the intelligible information. This perceivable information can be reduced by decreasing the correlation among these bits, pixels and blocks using certain techniques. This paper proposes a novel image encryption method based on changing the pixel positions as well as pixel values to confuse the relationship between the cipherimage and the plain-image. From the results, it is observed that the proposed technique significantly reduces the correlation among the pixels by shuffling the image matrix using a random vector. Moreover, the scheme has less computational complexity, good security and satisfies the property of confusion and diffusion.
