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