Abstract

Nowadays digital imagery is used for many purposes. Starting just as a hobby of photography up to the purpose of security or identification. For more sensitive purposes, an image needs to be encrypted so that the image is not recognized by an unauthorized person. In this study, hybrid transposition is used to encrypt and decrypt RGB images. The hybrid transposition here involves the process of randomization and repositioning of pixels before transposition is made. The performance of the encryption is measured by the correlation coefficient where the good result is indicated by the correlation coefficient value close to 0 (zero). The smallest coefficient values obtained are -0.0227 for test images in the form of chessboard pieces that have almost the same black and white areas. The decryption process produces the exact same image as the original image, this is indicated by the MAE value equal to 0 (zero) and the correlation coefficient equal to 1.0.
