| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | With the development of image recognition technology and the spread of mobile devices, photo-based information query services, in which users can get some guide information for a sight-seeing spot or a shop by taking its photo and sending it to an image recognition server, will be realized in the near future. However, this kind of client-server-based services can cause a privacy issue; the user's location history is disclosed to the server when the user uses the service many times. This is a kind of privacy leak from the user's viewpoint. To tackle the privacy issue, in this paper, we propose a novel framework of image recognition that can protect user's location history. In our experiments, the proposed framework can decrease the server's recognition accuracy to about 40% while keeping more than 90% of recognition accuracy on the user side. | |
