Abstract

An apparatus includes a memory of a mobile compute device, and a hardware processor of the mobile compute device. The hardware processor is configured to implement an operating system and an authentication module. The operating system is configured to receive a first authentication identifier, and is also configured to authorize use of the mobile compute device based on the first authentication identifier meeting a first criterion. The authentication module is configured to, in response to the operating system authorizing use of the mobile compute device, disable at least one function of the mobile compute device and request a second authentication identifier. The authentication module is also configured to receive the second authentication identifier. The authentication module is also configured to enable the at least one function in response to the second authentication identifier meeting a second criterion.

Claims (26)

1. A method, comprising:

receiving, at a native authentication application on a compute device, an indication from an operating system of the compute device that the operating system has authorized use of at least one function of the compute device, the indication from the operating system being sent by the operating system based on a valid first authentication;

disabling, via the native authentication application, the at least one function of the compute device in response to the indication from the operating system of the compute device that the operating system has authorized use of the at least one function of the compute device but before verifying a valid second authentication;

receiving, at the native authentication application, an indication of a location of the compute device;

confirming that the location is associated with the valid second authentication; and

enabling, via the native authentication application and based on the valid second authentication, the at least one function of the compute device.

2. The method of claim 1 , wherein the indication of the location of the compute device includes a global positioning service (GPS) location of the compute device.

3. The method of claim 1 , wherein the indication of the location of the compute device includes a presence of a specific wireless network detected by the compute device.

4. The method of claim 3 , further comprising:

confirming, at the native authentication application, that the specific wireless network is associated with the valid second authentication, the enabling, via the native authentication application being further based on the confirming that the specific wireless network is associated with the valid second authentication.

5. The method of claim 1 , wherein the disabling the at least one function of the compute device is in response to a predetermined period of inactivity of a user of the compute device.

6. The method of claim 5 , wherein the predetermined period of inactivity is based on the indication of the location of the compute device.

7. The method of claim 1 , wherein a timeout time period associated with the operating system periodically requesting an identifier associated with the valid first authentication is different from a timeout time period associated with the native authentication application periodically requesting the indication of the location of the compute device.

8. The method of claim 1 , wherein the indication of the location of the compute device includes at least one of an indication of a presence of a specific wireless access point or an indication of a presence of a Bluetooth® device.

9. The method of claim 1 , wherein the receiving the indication from the operating system of the compute device is based on the operating system receiving an authentication identifier.

10. The method of claim 9 , further comprising:

requesting the authentication identifier periodically via the operating system of the compute device; and

requesting the indication of the location of the compute device periodically via the native authentication application.

11. The method of claim 10 , wherein a timeout time period associated with the periodically requesting the authentication identifier via the operating system is different from a timeout time period associated with the periodically requesting the indication of the location of the compute device via the native authentication application.

12. The method of claim 9 , wherein the authentication identifier is a biometric authentication identifier.

13. The method of claim 1 , wherein the native authentication application is executed by the operating system but is not integrated with the operating system.

14. The method of claim 1 , further comprising:

registering the native authentication application with the operating system to receive the indication from the operating system that the operating system has authorized use of the at least one function.

15. The method of claim 1 , further comprising:

monitoring for the indication from the operating system broadcast by the operating system that the operating system has authorized use of the at least one function.

16. The method of claim 1 , wherein the disabling the at least one function of the compute device includes disabling use of the at least one function by applying an opaque view to a display of the compute device.
