Association of unique person to a mobile device using repeat face image matching
First Claim
1. A method for associating a physically identifiable feature of a person with a unique identifier of a mobile device utilizing at least a camera, at least a mobile signal sensor, and at least a processor for the association comprising the following steps, repeated for each visit of the mobile device:
- a. detecting the unique identifier of the mobile device using a mobile signal sensor for at least one physical location using a Mobile Device Visit Detection module, wherein a Mobile Device Visit Detection module captures a timestamp indicating the time when the mobile device was detected,b. capturing a plurality of input images of a face of at least a person at the physical location using at least a camera using a Candidate Face Collection module, wherein the Candidate Face Collection module captures the plurality of input images during a period of time when the mobile device was detected by the mobile signal sensors at the physical location,c. storing the unique identifier of the mobile device and plurality of input images in a database,d. clustering the plurality of input images into a face group using a Face Clustering module, ande. matching a particular face group to a particular mobile device using a Face to Mobile Matching module.

Abstract
A method and system for associating a physically identifiable feature of a person with the unique identifier of a mobile device carried by the person as detected across repeat visits to a physical location or multiple locations. Specifically, associating the face of a repeat visitor with a unique identifier of a mobile device, such as the device'"'"'s MAC address, by means of a repeat visit analysis without any explicit or voluntary participation of the person, for example, in a form of providing their information by participation in a survey. For each detection of a particular MAC address associated with a mobile device at a particular physical location, a set of candidate faces can be captured at that physical location. Revisiting faces can be identified and grouped together, and a probability that each group of faces is associated with a particular MAC address can then be calculated. After satisfying several constraints, a maximum probability can be determined, resulting in a match of a particular face to a particular MAC address.
