APPARATUS, SYSTEMS, AND METHODS FOR AUTHENTICATION ON A PUBLICLY ACCESSED SHARED INTERACTIVE DIGITAL SURFACE
First Claim
1. Apparatus for use with a publicly accessible digital surface to provide collaborative data processing among a plurality of users of the digital surface, the apparatus comprising:
- a personal digital device (PDD) adapted for storing and processing data for a user of the PDD, the PDD communicatively coupled with the digital surface; and
a stylus adapted for communication with the PDD and adapted for wireless communication with the digital surface, the stylus adapted to authenticate exchanges between the PDD and the shared digital surface initiated by the stylus in communications with the digital surface.

Abstract
Apparatus, systems and methods for authentication of use by multiple personal digital devices (PDDs) of a publicly shared digital surface. The digital surface provides a displayed work area for each personal digital device (PDD) in communication with the digital surface. Each PDD establishes secured communication with the digital surface identified by a security token. Each PDD may include a stylus adapted to receive the security token for use in exchanges with the digital surface to thereby associate the exchange with the authenticated PDD with which it is coupled. Actions taken by a user of a stylus on the digital surface are authenticated based on the security token and based on the location of the stylus when the action is requested.

12. A method operable a personal digital device (PDD) and a digital surface, the method comprising:
-
communicatively coupling the PDD to the digital surface; establishing between the PDD and the digital surface a security token associated with a session for exchange of information between the PDD and the digital surface; providing the security token to a stylus device communicatively coupled with the PDD; communicatively coupling the stylus with the digital surface; receiving the security token at the digital surface from the stylus; determining the location of the stylus on the digital surface; and authenticating actions of the stylus communicated from the stylus to the digital surface using the location of the stylus and the security token received from the stylus. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A system comprising:
-
a digital surface adapted for wireless communication with a plurality of personal digital devices (PDDs) and adapted to display information exchanged between the digital surface and each of the plurality of PDDs; at least one PDD adapted to store and process information on behalf of a user of the PDD wherein each PDD further comprises; a stylus adapted for wireless communication with the digital surface and communicatively coupled to its associated PDD, wherein the digital surface and each PDD are adapted to exchange information to establish a security token associated with said each PDD for exchanges of information among the plurality of PDDs through the digital surface, wherein the stylus associated with each PDD is adapted to receive the security token from its associated PDD and is adapted to communicate the security token to the digital surface, wherein the digital surface is adapted to detect the location on the digital surface of the stylus associated with each PDD and is adapted to receive the security token from the stylus associated with each PDD, wherein the digital surface is adapted to receive actions from a stylus associated with each PDD and is adapted to authenticate a received action based on the location of the stylus and based on the security token received from the stylus. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
