Research Team Develops Face-Mapping App For Global Smartphone Searching

View as: Print Mobile App Share:

Rice University researchers have developed a smartphone application that allows users to search images on other users' phones that have been transmitted by a centralized server. If the search finds a targeted image, the photo is sent back to the server for additional processing.

The application, called Theia, is designed for users that want to find a photo of someone or something that may have been taken unintentionally. Theia features a pair of key advancements to control search cost and enhance search efficiency. Incremental Search broadens search scope incrementally and exploits user feedback, while Partitioned Search leverages the cloud to lower the energy consumption of search in smartphones.

The researchers hope that Theia can be used to help identify people in recent child abduction or criminal manhunt cases. Although there are significant security issues, as users would have to approve opening up their phones to random searches by complete strangers, the researchers hope that Theia will be used for the public good.
