Internet has become an Integral part and prime need of every human being in their day to day life. People now prefer to do transaction over the internet than doing it offline as it reduces time consumption. In such scenarios, securing customer data is one of the biggest challenges for software developers. For this reason Security protocols like Blind Signature Scheme came into picture where requester is allowed obtain a signature from the signer who signs a message without reading the content of the message, and cannot link the protocol with the resulting message signature pair. Blind Signature scheme is mostly used for E-commerce applications like Digital payment system, Electronic-voting system as it provides security goals like blindness, untraceability, correctness and nonforgeability. Neal Koblitz and Victor S. Miller has presented Elliptic curve cryptography (ECC) which is an approach to public key cryptography based on algebraic structure of elliptic curves in over finite fields. Elliptic curve cryptosystem is more efficient than other public key cryptosystem due to difficulty in solving elliptic curve discrete logarithm problem. Using the benefits of elliptic curve cryptography we have presented implementation of blind signature scheme using JAVA.
