A new block cipher for image encryption based on multi chaotic systems
In this paper, a new algorithm for image encryption is proposed based on three chaotic systems which are Chen system, logistic map and two-dimensional (2D) Arnold cat map. First, a permutation scheme is applied to the image, and then shuffled image…

Iris images encryption based on QR code and chaotic map
In this paper an Iris image is encrypted based on QR (quick response)
code and chaotic map. The main idea of the proposed system is generating a QR code depending on the input text and then extract the features from QR code by using convolution,…
