Abstract: Technologies for authenticating a user of a computing device based on an authentication context state includes generating context state outputs indicative of various context states of a mobile computing device based on sensor data generated by sensors of the mobile computing device. An authentication manager of the computing device implements an authentication state machine to authenticate a user of the computing device. The authentication state machine includes a number of authentication states, and each authentication state includes one or more transitions to another authentication state. Each of the transitions is dependent upon a context state output. The computing device may also include a device security manager, which implements a security state machine that includes a number of security states. Transition between security states is dependent upon the present authentication state of the user. The device security manager may implement a different security function in each security state.

Abstract: In embodiments, apparatuses, methods and storage media (transitory and non-transitory) are described that are associated with user profile selection using contextual authentication. In various embodiments, a first user of a computing device may be authenticated and have an access control state corresponding to a first user profile established, the computing device may select a second user profile based at least in part a changed user characteristic, and the computing device may present a resource based at least in part on the second user profile. In various embodiments, the computing device may include a sensor and a user profile may be selected based at least in part on an output of the sensor and a previously stored template generated by a machine learning classifier.

Abstract: In one embodiment, a system comprises: a processor including at least one core to execute instructions; a plurality of sensors, including a first sensor to determine location information regarding a location of the system; and a security engine to apply a security policy to the system. In this embodiment, the security engine includes a policy logic to determine one of a plurality of security policies to apply based at least in part on the location information, where the location information indicates a location different than locations associated with the plurality of security policies. Other embodiments are described and claimed.
