Biometric based applications guarantee for resolving numerous security hazards. One among them, fingerprint recognition is most popular and successful method used for user identification. There are numerous methods available for person verification such as PIN/password, smart cards and so on. However, this knowledge based, token based security methods have crucial limitations that can be lost, stolen, or forgotten. Hence, this paper proposes a new algorithm for secure access control using fingerprint at high level. Utilizing the unique nature of human fingerprints while accessing the system, the fingerprint images of the authorized users are verified and validated by the fingerprint reader system. By comparing similarity between two feature sets, it is decided whether the two fingerprints match or not.
