  • Patent number: 10667132
    Abstract: This disclosure relates to systems and methods for managing mobile device network access. Systems and methods are described that allow for a mobile device to identify and selectively authenticate with one of a plurality of mobile network operators based on one or more policies associated with the mobile device and/or its user. Based on one or more policies, the mobile device may determine that a particular network is a preferred network and used provisioned electronic subscriber information stored on the device associated with the preferred network to connect to the preferred network. In various embodiments, other available networks may be checked, and the mobile device may switch networks in the event a new preferred network is identified.

  • Publication number: 20200162449
    Abstract: This disclosure relates to systems and methods for managing the operation of unmanned vehicles within policy managed locations and/or areas. In some embodiments, an unmanned vehicle may issue an operator signed request to enter a policy managed area and/or use a certain sensor system within a policy managed area to an unmanned vehicle management system. The unmanned vehicle management system may verify the operator's identity and associated rights with a trusted authority, identify a policy associated with the policy managed area, and enforce the identified policy in connection with generating a response to the request. In this manner, the use of unmanned vehicles and/or associated systems may be managed in accordance with certain policies and/or rules associated with a particular operating location and/or area.

  • Patent number: 10412071
    Abstract: 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.

  • Patent number: 10389868
    Abstract: This disclosure relates to, among other things, systems and methods for authenticating a device with a network carrier using secure hardware and software systems. Embodiments disclosed herein may provide for a hybrid SIM implementation that uses both trusted software and hardware. A hybrid SIM implementation consistent with aspects of the disclosed embodiments may leverage a relatively small amount of trusted hardware in conjunction with secure software to perform SIM-related operations. In various embodiments, such a hybrid solution may provide a SIM implementation that is more secure than solutions implemented by software alone, while still relating retaining some of the benefits of software solutions including improved update flexibility and/or carrier portability.
