Abstract
Purpose:
This paper presents a methodology for an image
cryptosystem to ameliorate the problems of many
existing digital image cryptosystems. The
cryptosystem is based on a gray code number
system.
Design/Methodology/Approach:
The gray code number system design is used to
transform the pixel information of an image.
Images are first binarized and based on the
location of a particular pixel value an algorithm is
selected for its transformation. This is later
followed by a gray code transformation and
reconstruction of the image (cipher).
Findings: Based on the mathematical analysis
performed with the encryption and decryption
designs, it is being envisaged that the proposed
technique will efficiently encrypt digital images.
Research Limitation: This paper only presents
the methodology for image cryptosystem based on
the gray code number system. The designed
system is yet to be implemented and tested to
confirm its efficiency.
Originality/Value: In the literature, a lot has been
done in the area of applying unconventional
number system in image encoding but this
research laid emphasis on the use of gray code
number system in image security. Many recent
journals were considered.
Keywords: Gray code, spatial domain, image
scrambling, image encryption, Java programming.
Paper Type: Research Paper.
