Claim:
A method for facilitating the detection of misuse of an identity during an electronic transaction at a first location, comprising the steps of: updating a cached position of a first wireless terminal; receiving a notification to authenticate the use of an identity at the first location, wherein the identity is associated with the first wireless terminal; determining whether a cached position is stale based on a predetermined time period; determining a second location of the first wireless terminal based on the cached pre-transaction position if the cached pre-transaction position is not stale; determining a third location of the first wireless terminal based on a requested position if the cached pre-transaction position is stale; determining whether the first and second locations match in geographical proximity; determining a third location of the first wireless terminal based on the requested position if the first location does not match in geographical proximity with the second location; determining whether the first and third locations match in geographical proximity; and generating an alert if the first and third locations do not match in geographical proximity.
