| Abstract(in English) | In face recognition systems, facial images are recognized by comparing features (template) extracted from them. This paper proposes a generation scheme of protected templates which are tolerant to template leakage and applies the scheme to the sparse representation-based face recognition. Template leakage leads to disclose users' personal information so that templates should be protected. The proposed scheme for template protection consists of random pixel permutation and downsampling. It is difficult to reconstruct visual information of facial images from the templates protected with the proposed scheme even though parameters for random pixel permutation and down-sampling are disclosed to the public. Furthermore, the templates protected with the proposed scheme can be more effectively compressed in terms of the data size than those with the conventional scheme using random projection because the histogram of the templates protected with the proposed scheme is denser than that with the conventional scheme. Experimental results with two major database of facial images demonstrate the effectiveness of the proposed scheme in terms of recognition performance, difficulty of visual information reconstruction, and data compression. |
