Claim:
1. A computer-implemented method to identify users at locations by comparing facial imaging of users against facial templates of users known to be at particular locations, comprising: broadcasting, by a computing device, an identifier associated with the computing device at a location; receiving, by the computing device and from one or more other computing devices, one or more facial templates, each facial template associated with a corresponding user associated with a corresponding user computing device that received the broadcasted identifier at the location and retransmitted the identifier to the one or more other computing devices, each facial template comprising a representation of a respective facial image of the respective user; storing, by the computing device, the one or more received facial templates; capturing, by a camera module of the computing device, a video feed of an environment external to the computing device; extracting, by the computing device, a facial image of a particular user from the video feed; generating, by the computing device, a facial template of the particular user based on the facial image of the particular user, wherein the facial template of the particular user is a representation of the facial image of the particular user; determining, by the computing device, a similarity between the generated facial template of the particular user and each of the one or more stored facial templates; identifying, by the computing device, a particular stored facial template as corresponding to the generated facial template of the particular user based on the determined similarity between the generated facial template of the particular user and the particular stored facial template exceeding a threshold value indicating that the stored facial template corresponds to the generated facial template of the particular user; transmitting, by the computing device, a response to a request to identify a user comprising an indication of the identified particular user.
