Image scrambling methods for digital image encryption

摘要

Information security is main concern at present. Image scrambling is one of the way to encrypt the digital image data. This paper present novel image scrambling method using Non-Commutative wavelet transform and Poker Shuffle transform. Due to suitability of Non-commutative Wavelet transform for image scrambling application over conventional Wavelet transform and non-linearity and non-analytic computation characteristics of Poker Shuffling increases the performance of proposed methodology. The proposed method compared with different existing image scrambling algorithm on the ground of image encryption.
