1. A method comprising the steps of: measuring one or more hidden states internal to a computing system related only to a user's active task with the computing system; using one or more deterministic mapping functions to directly map, without interpretation of the hidden states as being benign or malicious, the measurements to a representational output; and presenting the representational output in real-time and peripheral to the user's active task with the computing system, wherein the presented representational output does not label information pertaining to the hidden states.
