1. A method comprising:
- recognizing a pre-defined gesture performed by a stylus on a 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 touch screen;
determining a location at which the gesture was performed;
determining identity of the stylus performing the gesture;

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.

15. A method comprising:
-
receiving a command with a stylus to add an annotation to a document, wherein the document is displayed on a first computing device receiving input from the stylus and on a second computing device that does not receive input from the stylus; receiving identity of the stylus providing the command; linking the annotation to the identity of the stylus, based on receiving the command; displaying the document with the annotation on the first computing device; and displaying the document absent the annotation on the second computing device. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
