 Alignment-Free Fingerprint Cryptosystem Based On Multiple ...
In the functional transformation method, transformation was based on a Gaussian function. However, all three methods required alignment before transformation. To align the fingerprints, these methods used singular points. Authors in [5] proposed a cancelable fingerprint template using fingerprint minutiae....

1) The Issue of Feature Set Suitability and Fingerprint Matching With Template Protection Over the Encrypted Domain: In spite of significant improvement in recognition accuracy by using the Delaunay triangle-based structure in the unencrypted domain (without template protection) [11]–[18], (for example, the EERs of the method [18] are ......

1. Introduction
To relinquish the process of global registration and also reduce the impact of nonlinear distortion [29, 30], registration-free local structure based methods have been proposed; see, e.g., [5 – 11, 13, 14, 31 – 40]. In [5], Yang et al. proposed a cancelable template design based on geometric transformation. Each local Delaunay triangle ......

In , Rathgeb et al. presented an adaptive Bloom filter-based cancelable iris recognition system. The Bloom filters can map part of a binary template to Bloom filter-based representations, which are irreversible. This system is alignment-free because the Bloom filter-based features do not require image pre-alignment....
Performance evaluation of cancelable biometrics
Method 1: GRAY COMBO template based row shift and combination – Step 1: for each row shift circularly: – Step 2: combine two rows together to get a new one: • Intensity +, - • One row can be used more than once • Easy methods: odd+even, fold like a mirror 0-1 1-4-6 4-3-1 Combine rows 1, 3 to the new 1 st row Combine rows 2, 8 to the ...

Method and device for fingerprint authentication - SUPREMA ...
The fingerprint authentication method of claim 1, wherein the reference comparison data is selected based on a sum or an average of matching rates which are calculated by matching each of the partial fingerprint registration data with all of the other partial fingerprint registration data or based on the number of matched data when matching ......
Biometrics - Wikipedia
Several methods for generating new exclusive biometrics have been proposed. The first fingerprint-based cancelable biometric system was designed and developed by Tulyakov et al. Essentially, cancelable biometrics perform a distortion of the biometric image or features before matching. The variability in the distortion parameters provides the ......
