Image Encryption using Elliptic Curve Cryptography in MATLAB

This is the code which simulates the encryption and decryption of an image using random and private keys in MATLAB. The elliptic curve cryptography is applied to achieve the security of any image before transmitting it to some one so that no other can see the data hidden in the image. At the receiver end the destined user will already have the decryption key used for this. If key is altered, image will not be decrypted.
