Abstract

Digital Images for seamless transmission over mobile network are required to be ensured with authentication and increasing concern for their integrity, originality and non repudiation qualities. In this paper, a novel approach of digital signature scheme of an image is introduced. The proposed scheme consists of three main steps. First, pixel selection, second, pixel values digest through hash function, and finally, creation of digital signature using elliptic curve cryptography based on public key cryptosystem. In this process, the sender uses the private key for hash value encryption, and the recipient uses the public key for signature verification. Instead of directly sending an original image to the recipients, the embedded copy is sent with signed digital signature for authentication.
