An Implementation of Catmap-Rijndael (AES) Algorithm For Image Security (Case Study on A Software For Making Students Card At Universitas Jenderal Soedirman)
Abstract: The function of
image encryption is to transform known have that meaning to images that cannot
be read or irregular images in order to security. Storing the image data in
local computer system will bring some risks on the image security.
The aim of this research is to construct an image encryption system based
on Catmap-Rijndael algorithm. The system is implemented on a software form
making students card at Universitas Jenderal Soedirman. The result shows that
the combination of Catmap-Rijndael algorithm on bitmap image 200x200 pixel by
using 3 times repetition of the Catmap algorithm (with parameter a=1 and b=1)
can overcome the problem of textured of the object that caused by base colour
on the image and uniform histogram of the encrypted image in short time
process.
