9,813,897, "Systems and methods for vehicle policy enforcement," assigned to Intertrust Technologies.
This disclosure relates to systems and methods for vehicle policy management and enforcement. In certain embodiments, a method for enforcing a policy may include receiving policy information at a device including one or more conditions relating to a policy-managed location in a vehicle. A determination may be made whether the device is within the policy-managed location based on signals received by a short-range communication system included in the device and/or the vehicle. The received policy information may be evaluated to determine and implement one or more device actions associated with the one or more conditions.
9,807,069, "Secure transaction systems and methods," assigned to Intertrust Technologies.
Systems and methods are described that use tag authentication and presence verification techniques in connection with a variety of transactions. In certain embodiments, an authentication device may verify the authenticity of a secure tag by determining whether the secure tag stores secret information provisioned by a trusted authority. In some embodiments, such an authentication process may be performed without exposing the secret information to the authentication device, thereby maintaining integrity of the secure tag. In other embodiments, insecure tags and/or tags that do not include secret information are used.
