Abstract (in Japanese) (See Japanese page) 
(in English) Since biometric features are personal and irrevocable data, some schemes to protect the features (templates) extracted from biometric information are indispensable.
In the template protection, it is required that the cross-matching between templates protected by different keys is avoidable.
This paper proposes a scheme to improve cross-matching performance by extending the unitary transformation-based template protection method.
The proposed scheme can generate L-dimensional ($L geq N$) protected templates from N-dimensional original templates.
When a common key among all templates is used, the convensional unitary transformation-based template protection method has the same recognition performance as that of non-protected method, under the linear combination approach.
In this paper, it is shown that the proposed scheme keeps this property and, furthermore, can enhance the cross-matching performance.
By doing some face recognition experiments, the effectiveness of the proposed scheme is evaluated.
