Digital images can be secured by using methods of scrambling/encryption. A number of techniques have been proposed to encrypt the digital images. One such technique, which secures the content of the digital image by making it unreadable to the spying eyes, has been proposed in this paper. This paper proposes an image scrambling technique, using transforms for assorted color spaces. A comparison of...
In order to realize the scrambling aim of combination of pixels position substitution and the pixels values change, and moreover, in order to make up this deficiency which the low security of image encryption using one-dimensional chaotic system to encrypt digital image, a digital image encryption algorithm based on bit plane scrambling and multiple chaotic systems combination is proposed. Firstly,...
In the past decade, a number of image encryption algorithms based on chaotic maps have been proposed. Recently, an image encryption algorithm based on chaotic map lattice (CML) is proposed that allows direct encryption and decryption of color digital images. In this paper, we propose an enhanced CML based algorithm for image encryption to improve the security of the algorithm. The performance of the...
