Color Image Encryption using Random Password Seed and Linear Feed BackShift Register

Abstract

With the fast progress of electronic data exchange, information security was become more
important in data storage and transmission. And because of widely use of images in industrial
process, it is important to protect the confidential image data from unauthorized access. In this
paper, a proposed seed was generate as a key to a Linear Feed Back Shift Register (LFBSR) which
applied on the RGB color image (Bmp image) with random keys=2100. The performance of this
algorithm has been implemented on two types of Bmp image, the 8-bit Bmp image (palletized
image) and 24-bit Bmp image.
