Image Encryption for mobile devices

Encryption is used to transmit data in open networks with security. Each type of image has its own features, therefore different techniques can be adopted to protect the image from unauthorized access. Most of the available encryption algorithms are mainly used for large devices. There is no such image encryption algorithm with smallest key for smaller devices like cell phone, smart card etc. In this paper, we introduce an algorithm 'Elliptic Curve Cryptography for Image Encryption'. This algorithm has been applied as an efficient technique to resolve issues involving image encryption. The original image, represented as a set of two dimensional picture elements on a coordinate system can be encrypted using ECC.
