Abstract: A method and computer system for providing a measure of confidence of the identity of a user of a remote computer system. Information from the remote computer system about the purported identity of the user is received. A plurality of images of street scenes located within a geographical area of a neighbourhood surrounding a physical address associated with the user is collected along with the plurality of images of street scenes located outside of the geographical area. Signals are sent to the remote computer system allowing it to display the users of the streets scenes and asking the user to select those images which are in the geographical area. Information about the user's selection is received and a rating of confidence that the purported identify of the user is correct is made as a function of the user's selection.
