System and method for authentication with a computer stylus
First Claim
1. A device comprising:
- a display;
a digitizer sensor configured to detect input from a signal emitting stylus;
a circuit associated with the digitizer sensor and configured to;
recognize a pre-defined gesture performed by a stylus on the touch screen that displays a plurality of items, the pre-defined gesture defined as a user command to deny user access to one of the plurality of items displayed on the display;
determine a location at which the gesture was performed; and
determine an identity code of the stylus performing the gesture; and
a controller configured to;
compare the identity code of the stylus to a pre-stored identity code, wherein the pre-stored identity code is registered as authorized to perform secure operations with the digitizer sensor; and
deny user access to an item that was displayed at the location determined based recognizing the pre-defined gesture and based on the identity code matching the pre-stored identity code.

Abstract
A method for securing operation of a computing device operated with a stylus includes recognizing a pre-defined gesture performed by a stylus on a touch screen, the pre-defined gesture defined as a user command to lock an item displayed on the touch screen, determining a location of the gesture, determining identity of the stylus, locking an item displayed at the location determined, and recording identity of the stylus. A method for operating a computing device with a stylus includes receiving a command with a stylus to add restricted annotations to a document, receiving identity of the stylus, linking an annotation to the identity, restricting display of the annotation on the document to a computing device receiving input from the stylus; and displaying the document absent the at least one annotation on a computing device on which input from the stylus is not received.
