ABSTRACT:
A method and system are disclosed for authenticating on-line updates to listings maintained by a network-based directory service. An exemplary method for authenticating updates submitted on-line includes: (1) receiving an on-line update for a listing; (2) receiving origination information associated with a telephone call initiated by a user of a phone line corresponding to the listing; and (3) detecting a match between the origination information and at least a portion of the listing to authenticate the update. In one embodiment of the present invention, the origination information is a telephone number common to both the phone line from which the user is calling and the listing.
