Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to facilitate secure screen input. An example disclosed system includes a user interface (UI) manager to generate a UI comprising a quantity of ordinal entry points, each one of the quantity of ordinal entry points comprising a repeating selectable pattern, an ordinal sequence generator to generate an initial randomized combination of the quantity of ordinal entry points, the randomized combination stored in a trusted execution environment, and an offset calculator to calculate a password entry value by comparing an offset value and direction value retrieved from the UI with the initial randomized combination of the quantity of ordinal entry points.

Abstract: A platform including a security system is described. The security system comprises, in one embodiment, a multi-state system having a plurality of modes, available whenever the platform has a source of power. The modes comprise an unarmed mode, in which the security system is not protecting the platform, an armed mode, in which the platform is protected, the armed mode reached from the unarmed mode, after an arming command, and a suspecting mode, in which the platform is suspecting theft, the suspecting mode reached from the armed mode, when a risk behavior is detected.
