Random unitary matrices-based template protection methods have been proposed as one of biometric template protection schemes.
In the prior studies, a template is protected by two matrices, i.e, an unitary matrix with fixed values and one with random values.
These methods have lower calculation costs than these of the Gram-Schmidt orthogonalization, and can also generate integer protected templates.
However, these methods have been pointed out that the cross matching performance and the randomness of a protected template depend on the combination of random unitary matrices.
In this study,to overcome these problems, we propose a new generation method of a random unitary matrix.
In the proposed method, a template is protected by three matrices, i.e, an unitary matrix with fixed values and two unitary matrix with random values.
In addition, we propose to use a permutation matrix having plus or minus sign in a random order as a random matrix.
We perform some face recognition experiments to evaluate the cross matching performance and the randomness of a protected template and show the effectiveness of the proposed scheme. |
