An Analysis of Biometric Transformative Schemes

K. Kanagalakshmi, K. Lakshmipriya


There is a complexity in creating a secure Biometric system is protecting the templates of the user stored in Central Database. If there is any Compromise in saving templates then it will cause serious problem in security. The Cancellable Biometric is one of the safest methods used to store the template without duplication. In order to avoid the theft of iris biometric pattern, it is very must to design irrevocable and non- invertible transformation to create cancellable biometric template. In cancellable biometric many transformation techniques are used. In this attempt, two transformation techniques, i.e., Bio-hashing and Huffman Encoding with DCT are taken for comparative study in creating cancellable iris Biometric.


Biometrics, Cancelable Biometric Templates, BioHashing, Huffman Encoding & DCT.
