First Claim
Patent Images
1. A method of authenticating a mobile wireless user device by establishing a logical location for the device, the method comprising:
- gathering tokens from a number of other wireless devices using wireless communication between the user device and the other devices;
determining whether said tokens match a number of predetermined authentication tokens defining a known logical association for said user device; and
authenticating said user device on the basis of said known logical association, wherein said logical association is determined by a previous proximity association of said user device to said other devices.

Abstract
The present invention relates to authenticating a mobile device using location information associated with the device. The present invention provides a mechanism for authenticating a mobile device based on location related information or a “logical location”, but without requiring an actual location. The mobile user device gathers tokens such as SIM data from other wireless devices using wireless communication between the user device and the other devices. A server determines whether these tokens match predetermined reference information, and if so authenticates the user device.

14. A method of authenticating a mobile wireless user device by establishing a logical location for the device, the method comprising at the user device:
-
receiving at the user device an authentication challenge from a server; responding to said authentication challenge by gathering tokens from a number of other wireless devices using wireless communication between the user device and the other devices; forwarding said tokens to said server in response to said challenge, said tokens collectively defining a known logical association for said user device, said logical association being determined by a previous proximity association of said user device to said other devices.

15. A method of authenticating a wireless user device, the method comprising:
-
sending an authentication challenge to the user device, said authentication challenge requiring the user device to establish a logical association with a plurality of other devices by receiving wirelessly communicated tokens from said other devices, said tokens collectively defining a known logical association for said user device, said logical association being determined by a previous proximity association of said user device to said other devices; receiving tokens associated with a number of other wireless devices from the user device in response to the challenge; determining whether said tokens match a number of predetermined authentication tokens establishing said known logical association; and
,in the event of a match, authenticating said user device.

17. A system for authenticating a wireless user device, the system comprising:
-
means arranged to gather tokens from a number of other wireless devices using wireless communication between the user device and the other devices; means arranged to determine whether said tokens match a number of predetermined authentication tokens defining a known logical association for said user device; and means arranged to authenticate said user device on the basis of said known logical association, wherein said logical association is determined by a previous proximity association of said user device to said other devices.

18. A wireless user device comprising:
-
means arranged to receive an authentication challenge from a server; means arranged to respond to said authentication challenge by gathering tokens from a number of other wireless devices using wireless communication between the user device and the other devices; and means arranged to forward said tokens to said server in response to said challenge, said tokens collectively defining a known logical association for said user device, said logical association being determined by a previous proximity association of said user device to said other devices.

19. A server for authenticating a wireless user device, the server comprising:
-
means arranged to send an authentication challenge to the user device, said authentication challenge requiring the user device to establish a logical association with a plurality of other devices by receiving wirelessly communicated tokens from said other devices, said tokens collectively defining a known logical association for said user device, said logical association being determined by a previous proximity association of said user device to said other devices; means arranged to receive tokens associated with a number of other wireless devices from the user device in response to the challenge; means arranged to determine whether said tokens match a number of predetermined authentication tokens establishing said known logical association; and
,authentication means arranged, in the event of a match, to authenticate said user device.
