Analysis and Implementation of Selective Image Encryption Technique Using Matlab

Abstract

Encryption plays a very significant role in secure transmission of digital images from one place to another. There are a number of encryption algorithms available which perform the task of encryption. However some algorithms are fully layered which perform the encryption of the whole content of the images. But sometimes there is a requirement of partial image encryption so that there is reduced execution time and hence increases in performance. This type of partial image encryption can be achieved through Selective image encryption technique. This paper aims to propose an analysis and implementation of Selective image encryption technique using Matlab.
