1. A stolen device detection method, the method comprising the steps of:
- storing, in a storage device, a list of device identifiers corresponding to stolen devices;
receiving an IP packet from a device including an IP address associated with said device;
using said IP address associated with said device to determine a device identifier also associated with said device;
comparing the determined device identifier to said stored list of device identifiers corresponding to stolen devices; and
determining that said IP address corresponds to a stolen device when said determined device identifier matches a device identifier in said stored list.

Abstract
Methods and apparatus for determining, in a reliable manner, a port, physical location and/or device identifier, such as a MAC address, associated with a device using an IP address and for using such information, e.g., to support one or more security applications is described. Supported security applications include restricting access to services based on the location of a device seeking access to a service, determining the location of stolen devices, and verifying the location of the source of a message or other IP signal, e.g., to determine if a prisoner is contacting a monitoring service from a predetermined location.

10. A system for detecting stolen devices using IP addresses, the system comprising:
-
a stored list of device identifiers corresponding to stolen devices; means for receiving an IP packet from a device including an IP address associated with said device; means for determining a device identifier associated with said device from said IP address associated with said device; means for comparing the determined device identifier to said stored list of device identifiers corresponding to stolen devices; and means for determining that said IP address corresponds to a stolen device when said determined device identifier matches a device identifier in said stored list. - View Dependent Claims (11, 12, 13)
