Contextual identification and information security

Abstract:

A system may identify a user based on inputs from multiple devices. The system may determine a confidence score based on the probability that the system accurately identifies the user. The system may provide a permissions level based on the confidence score. The permissions level may affect the type of interactions the user may perform with a device. The system may determine a privacy level for an interaction based on determining whether the user is in a public or private setting.
