Abstract
Techniques are provided for the lightweight authentication of a user to an application, a computer or other device. An interaction element such as a stylus, a pen or marker is uniquely identified. The interactive element is associated with a user. The interaction element provides a means for interacting with the application. The proximity of the identification element within the interaction element during data entry operations to the authentication sensor signals the controlled application that the user has been authenticated.
