Abstract

In this manuscript, a new encryption approach for multiple images is proposed based on 4-weighted fractional
frequency transform (4-WFRFT) domain. First, the low frequency-components of all the images are obtained by
applying Fourier Transform on each image, which positioned at corner position of image, shifted to the central
position. Low-frequency component of each individual image is then scrambled with help of Arnold cat map
with its parameters and combined all scrambled image to form a single image with the same size that of original
image which is now ready for encryption process. Here, parameters of Arnold cat map and transform order of 4-
WFRFT treated as secret keys which are converted from Permanent Account Number (PAN) of authorize person.
The encrypted image information generated by authorize person can be recovered by applying PAN at receiver
side.
