Claims20
A method of operating a user device, comprising:
- detecting whether the user device is located within a restricted zone by a monitoring entity of the user device;
- and
- limiting access to the user device by the monitoring entity in response to detecting the user device as being outside the restricted zone.
A non-transitory computer readable storage medium, comprising instructions which, when executed by a processor, performs steps of operating a user device, the steps comprising:
- decrypting a storage device of the user device after the user device is powered on;
- launching an operating system of the user device from the decrypted storage device;
- and
- performing a monitoring operation and detecting whether a risk condition of the user device exists.
A user device, comprising:
- a processor;
- a storage device coupled to the processor;
- and
- a monitoring entity coupled to the processor and the storage device and configured to perform the steps of:
- detecting whether the user device is located within a restricted zone;
- and
- limiting access to the user device in response to detecting the user device as being outside the restricted zone.
