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 central processer unit disposed in the housing and operable to process information; memory disposed in the housing and interfaced with the CPU, the memory operable to store information; an operating system stored in the memory and operable to execute on the CPU, the operating system having a security subsystem to lock access to information and to unlock access to information in response to an operating system authentication input by an end user; plural sensors disposed in the housing and operable to detect conditions external to the housing; and a context engine operable to execute on one or more processing components disposed in the housing, the context engine establishing a context based upon external conditions sensed by the plural sensors in response to the operating system authentication input by the end user, the context including at least a wireless local area network identifier, an image captured by a camera, and motion detected by an accelerometer, the security subsystem locking access to a first set of information after a first time out period having a length set based on context sensed by all of the wireless local area network identifier that is detected, the camera image that is detected, and the motion that is detected by the accelerometer defines the context, the first set of information comprising less than all information accessible at the information handling system, and locking access to the first set of information after a second time out period different from the first time out period if only one of the wireless local area network identifier that is detected, the camera image that is detected or the motion that is detected by the accelerometer defines the context, the security subsystem locking access to all information accessible at the information handling system after a third time out period different from the first and second time out periods.
