| Abstract(in English) | Currently, huge amounts of image/video are being recorded and uploaded every day by surveillance systems or SNS services etc. Recent popularized edge/cloud computing is widely used for handling and analysis such huge amount of image/video data. 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. In this manuscript, we propose an encrypted image classification method by using secure sparse coding based on a random unitary transform. We carry out experiments of detecting human in images on the INRIA person dataset. It is shown that the encrypted mage classification method enables us to not only protects images, but also have the same classification performance as that of sparse coding with unprotected images. |
