WebAug 13, 2024 · Random projection can be utilized for creating cancelable biometric templates [ 36 ]. Random projection is performed through the multiplication of the obtained feature vector with a random matrix as follows. {\mathbf {y}} = {\mathbf {Mx}} (1) where {\mathbf {x}} is the feature vector extracted from the iris image, \mathbf {M} is the … Weboutputs a pre-hash vector which is then converted to a biometric hash vector through random projection and thresholding. We use angular distance measure to train pre-hash vectors which is more related with the Hamming distance that is used between hashes in veri cation time. Our experiments show that the introduced method can outperform a WebFeb 20, 2024 · 2.3 Cancelable Biometrics Realization with Multispace Random Projections One of the main disadvantages of biometrics is that if the biometric template is compromised then it cannot be changed. To meet this disadvantage the author proposed an approach which is a two-factor biometric formulation [ 5 ]. rayna iranian princess milwaukee
