Outsource Photo Sharing and Searching for Mobile Devices With Privacy Protection
With the proliferation of mobile devices, cloud-based photo sharing and
searching services are becoming common due to the mobile devices' resource
constrains. Meanwhile, there is also increasing concern about privacy in
photos. In this work, we present a framework \ourprotocolNSP, which enables
cloud servers to provide privacy-preserving photo sharing and search as a
service to mobile device users. Privacy-seeking users can share their photos
via our framework to allow only their authorized friends to browse and search
their photos using resource-bounded mobile devices. This is achieved by our
carefully designed architecture and novel outsourced privacy-preserving
computation protocols, through which no information about the outsourced photos
or even the search contents (including the results) would be revealed to the
cloud servers. Our framework is compatible with most of the existing image
search technologies, and it requires few changes to the existing cloud systems.
The evaluation of our prototype system with 31,772 real-life images shows the
communication and computation efficiency of our system.Comment: 10 pages, 13 figure
