A High Level System of Providing Security to the Fingerprint Template Using Bio-tokens

Fuzzy vault fingerprint Cryptosystem uses pair polar framework. In this framework the number of fake minutiae is added to the genuine minutiae to hide the original features to provide security to the template. The chaff points are placed at a distance to provide a frame work to hide the genuine features of the fingerprint template. The genuine and fake minutiae are distinguished. The implementation of this system provides high recognition accuracy. But when the genuine features are identified the template gets compromised. When the user has the access to multiple vaults the genuine features can be identified. To overcome this compromisation bio-token concept is proposed. It is also a cancellable biometric technique which provides identity to the template. The binary vault code is generated for the constructed vault and then it is stored in the database. The security to the template is enhanced. The EER can be decreased to about 30%. This system performs well in providing security to the fingerprint template.
