Context analysis at an information handling system to manage authentication cycles

摘要

Context captured with sensors of an information handling system is applied to selectively lock access to currently unlocked information, with conditions for locking access based upon the context. Nervous states enforce locking of selected information based upon the confidence of the security of the information under sensed external conditions. Increased sensitivity for locking access includes reduced timeouts to a lock command, increased response to sensed conditions, and more rapid response where unlocked access is to sensitive information.

主权项

1. An information handling system comprising:
a housing; a processing components disposed in the housing and operable to cooperate to process information; one or more input/output (I/O) devices interfaced with the processing components and operable to accept touch inputs; a display interfaced with the processing components and operable to present information as visual images; one or more optical sensors operable to sense light for adapting brightness of the display; one or more cameras operable to capture images proximate the display; one or more wireless communication devices operable to communicate with wireless signals; and a nervous state engine operable to execute on one or more of the processing components, the nervous state engine transitioning between plural nervous states, each nervous state disenabling access to currently authorized secure information with predetermined conditions defined by each nervous state, the nervous state engine transitioning between nervous states based upon a context sensed by one or more of the I/O devices, optical sensors, camera and wireless communication devices; wherein the nervous states include at least a first user-present nervous state that transitions to a second user-absent nervous state, the first user-present nervous state having one or more indications that an authorized user is proximate the information handling system, the first user-present nervous state disenabling a first access if a first predetermined condition is detected, the second user-absent nervous state having one or more indications that an authorized user is not proximate the information handling system, the second user-absent state disenabling a second access if the first predetermined condition is detected; and wherein the predetermined condition comprises a detection of discontinuity between the amount of light sensed by the one or more optical sensors and the one or more cameras, the second access comprising a complete lock of the information handling system.
