Blind Signature Theory was introduced in 1982. After that many other experts together introduced a new concept, which is called Fair Blind Signature to improve the weakness of the Blind Signature Theory. Although many enhancements were made after Fair Blind Signature Theory’s first introduction, its applications are still rare. However, we believe that Blind Signature Theory can substantially improve the system security and performance if it applies to a suitable application such as anonymous poll system, e-auction and e-cash etc. Therefore, We propose and implement a web-based auction system in which we applied the blind signature theory. We build a web-based auction system that can be achieved by purely applying Blind Signature Theory. The result of the implementation shows that blind signature theory is feasible and could easily applied to a web-based auction system.
