Image Encryption Scheme Based on Filter Bank and Lifting

Abstract

In this paper, the quality of image encryption using filter bank with lifting scheme has been studied and evaluated. Many extensive techniques have been applied to examine the security of the image encryption using the filter bank cipher with one or two rounds. To analyze and evaluate the proposed scheme, many parameters have been employed, such as, histogram analysis, correlation coefficient, global entropy, block entropy, avalanche effect, number of pixel change rate (NPCR), unified average change intensity (UACI), compression friendliness, exhaustive key analysis, and key sensitivity test. The simulation results showed that, the quality of the image encryption passes all these tests. Moreover, it reaches or excels the current state-of-the-arts. So that, the proposed image encryption process produces random-like output from the statistical point of views.

Bit-Level Image Encryption Algorithm Based on Composite Chaotic Mapping

“…Then, the one-dimensional sequence Q is converted to a bit matrix M 2 , which size is h×8w. Finally, according to the order from left to right and from top to bottom, each 8 bits are converted to an integer [14][15][16]. In this way, the bit level image scrambling is completed.…”
