Abstract: A method for authenticating a user prior to allowing a transaction or access to a website, in which the user's computer is identified via a recognized computer signature that is associated with a geographical location. The location of the user's cell phone is compared to the associated location, and the transaction or access is permitted if the difference in locations is within a predetermined acceptable distance.

Abstract: The invention provides a method and system for accomplishing two-factor authentication for internet transactions, wherein the user of the device through which the transaction is negotiated needs to give only a single yes/no verification to the system. In some embodiments, the second factor authentication is automated without any action on the part of the user. The method calls on the user's wireless voice device for the detection of environmental wireless signals (“Short Distance Wireless Information” or “SDWI”), and uses these signals collectively as a “fingerprint” that uniquely identifies the wireless signals near the wireless voice device. The system stores these SDWI fingerprints, and later uses the stored information to establish whether or not the user's wireless voice device is near a previously-recognized SDWI.

Abstract: A method and system for acquiring an internet user's consent to be geographically located via at least two independent sources of geographical information, where at least one independent source of geographical information is the wireless location of the internet user's communication voice device. The method does not require any user intervention other than the user's interaction with an internet site via the internet user's internet browser.

Abstract: The invention provides methods for facilitating the identification of internet users, for detection of misuse of an identity during an electronic transaction, and for controlling access to web sites. The method employs determining the location of the user's wireless communication device, based on the geographical proximity of Wi-Fi locations and cached position information.

Abstract: The invention provides a method for detection of misuse of an identity during an electronic transaction. In a first embodiment, the method comprises the steps of: receiving a notification to authenticate the use of an identity at a first location, wherein the identity is associated with a first wireless terminal; determining an approximate location of the first wireless terminal based on cached position information, the approximate location of the first wireless terminal being a second location; determining whether the first and second locations match in geographical proximity; and generating an alert if the first and second locations do not match in geographical proximity. In a second embodiment, an approximate location of the first wireless terminal is determined based on cached position information stored in a GPS position database. In a third embodiment, the approximate location of the first wireless terminal is automatically determined prior to the initiation of a transaction.
