Patent ID: 8725652

Claim:
A server computer comprising: a processor; a storage medium coupled to the processor and storing associating information between accelerometer data of a plurality of users and one or more payment devices; and an interface module configured to communicate with one or more external systems, wherein the processor in conjunction with the interface module is programmed to: receive an authorization request for processing a payment transaction, the authorization request including information about a first payment device; determine a user associated with the first payment device; send an authentication request to a user device associated with the user requesting the user to send a video of the user; receive the video of the user in response to the authentication request, the video of the user including first accelerometer data associated with the video; compare the video of the user to one or more videos associated with a plurality of users to determine whether a match exists; based on a result of the comparison of the video of the user to the one or more videos associated with the plurality of users, extract the first accelerometer data from the received video of the user and compare that to the accelerometer data associated with the plurality of users; determine that a second accelerometer data from the accelerometer data of the plurality of users matches with the first accelerometer data; and send the authorization request message to an issuer computer associated with the first payment device.
