Abstract(in English) | In this paper,we propose a privacy-preserving SVM processing method with templates protected by using a random unitary transformation, and evaluate the effectiveness of the proposed scheme, where templates mean features extracted from images or biometric traits. Recently, cloud computing is spreading in many fields. However, the cloud computing has some serious issues for end users, such as unauthorized use and leak of data, and privacy compromise, due to unreliability of providers and some accident. Because of such a situation, this paper considers privacy-preserving SVM processing. It is shown that the unitary transformation-based template protection method enables us to not only protect templates, but also have the same classification performance as that of SVM processing with unprotected templates. Moreover, we consider how to update/assign secret keys, and then describe that it is possible to provide a higher performance than with unprotected templates. Some face recognition experiments are carried out as a SVM classification scheme to experimentally confirm the effectiveness of the method. |
