Encryption systems have been developed for image viewing applications using the Hill Cipher

algorithm. This study aims to evaluate the image encryption quality of the Hill Cipher algorithm. Several

traditional metrics are used to evaluate the quality of the encryption scheme. Three of such metrics have

been selected for this study. These include, the Colour Histogram, the Maximum Deviation (comparing

the original image) and the Entropy Analysis of the encrypted image. Encryption quality results from all three

schemes using a variety of images show that a plain Hill Cipher approach gives a good result for all kinds of

images but is more suited for colour dense images.
