A Global Positioning Satellite (GPS) receiver is used to determine the location of the PC and restrict access to one or more features based on a previously-defined security policy. The GPS receiver is bound to a secure and/or unique component of the PC (e.g., a Trusted Platform Module (TPM)) to ensure that the receiver is not replaced with another, unapproved GPS receiver. A location-based security policy is used to specify security zones and the restrictions that are imposed when the the computer is within or outside of the zones. During normal use, the GPS card is automatically used to verify the location of the PC and access to various features is either granted or blocked based on the location-based security policy. Advantages of this method include: accurate implementation of the "where you are" paradigm, reduction of concern regarding forgotten passwords or stolen tokens, and implementation of multiple zone-specific security policies.
