Abstract

A method of enabling a lock screen of an electronic device operating an electronic device that includes an electronic processor and a display screen. The method includes receiving, by the electronic processor, a request to unlock the electronic device. The method further includes determining, by the electronic processor, an authentication state for the electronic device. The method further includes, determining, by the electronic processor, a lock screen authentication mode based on the authentication state, and displaying, on the display screen, a lock screen including the lock screen authentication mode. The electronic device includes a display screen and an electronic processor. The electronic processor is configured to receive a request to unlock the electronic device. The electronic processor is further configured to determine an authentication state for the electronic device, determine a lock screen authentication mode based on the authentication state and display on the display screen, a lock screen including the lock screen authentication mode.

First claim

We claim:

1 . A method of enabling a lock screen of an electronic device that includes an electronic processor and a display screen, the method comprising:
receiving, by the electronic processor, a request to unlock the electronic device; determining, by the electronic processor, an authentication state for the electronic device; determining, by the electronic processor, a lock screen authentication mode based on the authentication state; and displaying, on the display screen, the lock screen including the lock screen authentication mode.

2 . The method of claim 1 , wherein determining the lock screen authentication mode includes
when the authentication state is not valid, determining a relatively lower authentication level relative to when the authentication state is valid, and when the authentication state is valid, determining a relatively higher authentication level relative to when the authentication state is not valid.

3 . The method of claim 2 , further comprising:
upon receiving a successful user authentication, determining, by the electronic processor, a home screen state; and displaying, on the display screen, a home screen based on the authentication state and the home screen state.

4 . The method of claim 2 , further comprising:
determining, by the electronic processor, a network connectivity requirement for the electronic device; and determining, by the electronic processor, a network connectivity state for the electronic device.

5 . The method of claim 4 , wherein determining the network connectivity state for the electronic device includes
determining, by the electronic processor, whether an identity server connection exists.

6 . The method of claim 4 , further comprising:
upon receiving a successful user authentication, displaying, on the display screen, a home screen based on the network connectivity requirement, the network connectivity state, and the authentication state; wherein determining the lock screen authentication mode is further based on the network connectivity requirement and the network connectivity state.

7 . The method of claim 4 , further comprising:
when network connectivity is required and exists, or network connectivity is not required, determining, by the electronic processor, a home screen state for the electronic device; and determining, by the electronic processor, a pre-selected lock screen authentication mode based on the home screen state; wherein determining the lock screen authentication mode is further based on the home screen state; and the lock screen further includes the pre-selected lock screen authentication mode.

8 . The method of claim 7 , further comprising:
receiving, by the processor, an authentication mode selection; and upon receiving a successful user authentication, displaying, on the display screen, a home screen based on the authentication mode selection.

9 . The method of claim 8 , wherein receiving the successful user authentication includes receiving a valid single sign-on token.

10 . The method of claim 8 , wherein receiving the successful user authentication includes receiving a valid secure container credential.

11 . An electronic device, the electronic device comprising:
a display screen; and an electronic processor configured to
receive a request to unlock the electronic device;
determine an authentication state for the electronic device;
determine a lock screen authentication mode based on the authentication state; and
display on the display screen, a lock screen including the lock screen authentication mode.

12 . The electronic device of claim 11 , wherein the electronic processor is further configured to
when the authentication state is not valid, determine a lock screen authentication mode including a relatively lower authentication level relative to when the authentication state is valid, and when the authentication state is valid, determine a lock screen authentication mode including a relatively higher authentication level relative to when the authentication state is not valid.

13 . The electronic device of claim 12 , wherein the electronic processor is further configured to
upon receiving a successful user authentication, determine, a home screen state; display, on the display screen, a home screen based on the authentication state and the home screen state.

14 . The electronic device of claim 12 , wherein the electronic processor is further configured to
determine a network connectivity requirement for the electronic device; and determine a network connectivity state for the electronic device.

15 . The electronic device of claim 14 , wherein the electronic processor is further configured to
determine whether an identity server connection exists; wherein the network connectivity state is based on whether the identity server connection exists.

16 . The electronic device of claim 14 , wherein the electronic processor is further configured to
upon receiving a successful user authentication, display, on the display screen, a home screen based on the network connectivity requirement, the network connectivity state, and the authentication state; wherein the lock screen authentication mode is further based on the network connectivity requirement and the network connectivity state.

17 . The electronic device of claim 14 , wherein the electronic processor is further configured to
when network connectivity is required and exists, or network connectivity is not required, determine a home screen state for the electronic device; and determine a pre-selected lock screen authentication mode based on the home screen state; wherein the lock screen authentication mode is further based on the home screen state; and the lock screen further includes the pre-selected lock screen authentication mode.

18 . The electronic device of claim 17 , wherein the electronic processor is further configured to
receive an authentication mode selection; and upon receiving a successful user authentication, display, on the display screen, a home screen based on the authentication mode selection.

19 . The electronic device of claim 18 , wherein the successful user authentication is a valid single sign-on token.

20 . The electronic device of claim 18 , wherein the successful user authentication is a valid secure container credential.
