Contextual device locking/unlocking

One or more computer-readable non-transitory storage media embodying software operable when executed to:

• by a computing device associated with a first user, detect an event using one or more sensors of the computing device;
• by the computing device, in response to detecting the event, determining unique data associated with a second user, wherein the event was triggered by the second user;
• by the computing device, assess a state of the computing device;
• by the computing device, identify the second user based on social-networking information associated with the first user and the second user, wherein the computing device looks up the social-networking information using the unique data;
• and
• by the computing device, update a lock status of the computing device, wherein the lock status comprises a level of access to access interfaces of the computing device, functionality of the computing device, or content accessible from the computing device, the updating based on the event, the social-networking information, and the state, and wherein the level of access of the updated lock status is based on the social-networking information.

A computing device comprising:

• one or more processors of a computing device associated with a first user;
• a sensor;
• and
• a memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to:
• detect an event using the sensor;
• in response to detecting the event, determine unique data associated with a second user, wherein the event was triggered by the second user;
• assess a state of the computing device;
• identify the second user based on social-networking information associated with the first user and the second user, wherein the processors look up the social-networking information using the unique data;
• and
• update a lock status of the computing device, wherein the lock status comprises a level of access to access interfaces of the computing device, functionality of the computing device, or content accessible from the computing device, the updating based on the event, the social-networking information, and the state, and wherein the level of access of the updated lock status is based on the social-networking information.
