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.
