Maintaining user authenticaitons with common trusted devices

摘要

Various embodiments are generally directed to an apparatus, method, and other techniques to maintain user authentications with common trusted devices. If a user is in possession of a first computing device (e.g., a smartphone), an unlocked state of the first trusted device is maintained if the user is using a nearby trusted device (e.g., a computer) within a certain amount of time. If the first trusted device is in a pocket or other container, a longer span of time is granted to the user to register an on-body state.

主权项

1. An apparatus for maintaining a user authentication status comprising:
a processor circuit; a network interface to exchange data communications with a trusted device; an activity-detection component to determine whether the trusted device has received user input within a screen-lock-timeout time of the apparatus; an in-container detection component to determine whether the apparatus is disposed within a container based at least in part on data received from an in-container detection sensor; an on-body detection component to determine whether the apparatus is in an on-body state based at least in part on data received from an on-body detection sensor; and a user-authentication component to authenticate the user to the apparatus and thereafter transition a display of the apparatus from a locked state to an unlocked state and to maintain the unlocked state of the display of the apparatus for a length of time greater than the screen-lock-timeout time based on a determination that the trusted device has received user input user within the screen-lock-timeout time of the apparatus, a determination that the apparatus is disposed within the container, and a determination that the apparatus is in the on-body state.
