Method for detecting misuse of identity in electronic transactions
The invention provides methods for determining whether a transaction has taken place in geographic proximity to a wireless device. Upon receiving a notification to authenticate the use of an identity at a transaction location, where the identity is associated with a wireless terminal, the method determines an approximate location of the wireless terminal based on cached position information, GPS location, cellular geo-location, and/or Wi-Fi geolocation, and determines whether one or more of these is in geographic proximity to the location of the transaction.
1. A method of detecting possible fraudulent use of an identity associated with a user in a transaction, comprising:
(a) associating a user identity with a wireless terminal;
(b) caching on the wireless terminal a pre-transaction second location of the wireless terminal;
(c) receiving a notification to authenticate the use of the identity at a first location;
(d) obtaining from the wireless terminal the cached pre-transaction second location of the wireless terminal;
(e) obtaining a first time stamp for the first location and a second time stamp for the second location, and calculating a speed required to move from the first location to the second location in the time elapsed between the first time stamp and the second time stamp;
(f) generating an alert if the speed is above a predetermined value; and
(g) communicating the alert to a predetermined device.
2. The method of claim 1 , wherein the second location in step (b) is identified via detection of a Wi-Fi unique ID corresponding with a known location, said Wi-Fi unique ID comprising a MAC Address.
3. The method of claim 1 , further comprising the step of determining whether the second location cached at step (b) is stale.
4. The method of claim 3 , further comprising the step of requesting a fresh second location of the wireless terminal if the second location cached at step (b) is determined to be stale.
5. The method of claim 3 wherein the cached second location is determined to be stale if the cached second location has not been updated within a predetermined time period.
6. The method of claim 1 wherein the first location is the user's home address.
7. The method of claim 1 wherein the first location is the user's work address.
8. The method of claim 1 wherein the notification to authenticate is received in connection with an online transaction, and the first location and second location are obtained vii the Internet.
9. The method of claim 1 wherein the first location is the user's work address.
10. The method of claim 1 wherein the notification to authenticate is received in connection with an online transaction, and the first location and second location are obtained via the Internet.
11. A method of detecting possible fraudulent use of an identity associated with a user in a transaction, comprising:
(a) associating the user identity with a wireless terminal;
(b) receiving a notification to authenticate the use of the identity at a first location;
(c) obtaining a pre-transaction second location of the wireless terminal based on cached position information stored on the wireless terminal, if the cached position information is stored on the wireless terminal; otherwise
(d) obtaining from the wireless terminal a post-transaction second location of the wireless terminal;
(e) obtaining a first time stamp for the first location and a second time stamp for the second location, and calculating a speed required to move from the first location to the second location in the time elapsed between the first time stamp and the second time stamp;
(f) generating an alert if the speed is above a predetermined value; and
(g) communicating the alert to a predetermined device.
12. The method of claim 11 , wherein the second location in step (c) is identified via detection of a Wi-Fi unique ID corresponding with a known location, said Wi-Fi unique ID comprising a MAC Address.
13. The method of claim 11 wherein the first location is the user's work address.
14. A method of detecting possible fraudulent use of an identity associated with a user in a transaction, comprising:
(a) associating a user identity with a wireless terminal;
(b) caching on a remote database a pre-transaction second location of the wireless terminal;
(c) receiving a notification to authenticate the use of the identity at a first location;
(d) obtaining from the remote database the cached pre-transaction second location of the wireless terminal;
(e) obtaining a first time stamp for the first location and a second time stamp for the second location, and calculating a speed required to move from the first location to the second location in the time elapsed between the first time stamp and the second time stamp;
(f) generating an alert if the speed is above a predetermined value; and
(g) communicating the alert to a predetermined device.
15. The method of claim 14 , wherein the second location in step (b) is identified via detection of a Wi-Fi unique ID corresponding with a known location, said Wi-Fi unique ID comprising a MAC Address.
16. The method of claim 14 , further comprising the step of determining whether the second location cached at step (b) is stale.
17. The method of claim 16 , further comprising the step of requesting a fresh second location of the wireless terminal if the second location cached at step (b) is determined to be stale.
18. The method of claim 16 wherein the cached location is determined to be stale if the cached second location has not been updated within a predetermined time period.
19. The method of claim 14 wherein the first location is the user's work address.
20. The method of claim 14 wherein the notification to authenticate is received in connection with an online transaction, and the first location and second location are obtained via the Internet.
