Your Video Can ID You Through Walls

For the first time ever, determining whether the person behind a wall is the same person who appears in a given video footage, using only a pair of WiFi transceivers outside, is now possible, thanks to researchers from UC Santa Barbara.

This novel video-WiFi cross-modal gait-based person identification system, which they refer to as XModal-ID (pronounced Cross-Modal-ID), could have a variety of applications, from surveillance and security to smart homes. For instance, consider a scenario in which law enforcement has a video footage of a robbery. They suspect that the robber is hiding inside a house. Can a pair of WiFi transceivers outside the house determine if the person inside the house is the same as the one in the robbery video? Questions such as this have motivated this new technology.
