Chaos theory based cryptography in digital image distribution : visibility controlled image encryption scheme (ViCIEn)

Abstract

The amount of usual information available in digital format has grown exponentially in recent years due to the wide availability of equipments such as digital cameras and camera phones, changes in the way people socially interact by setting up community web pages, wide spread use of the Internet in all types of personal and business activities, and developments in high speed transmission of digital images with high reliability./ However, the wide accessibility of the Internet and its connected hosts and availability of technology to capture network traffic or penetrate hosts have made digital images vulnerable to unauthorized access while in storage and during transmission over a network. Hence users of the Internet and application that use or process digital images need to address security issues to protect commercial value of images and also ensure user privacy and other issues.
