Method and a system for secure management of information from an electronic pen

Abstract

In an information management system for handling digital position data recorded by an electronic pen, the pen is controlled to convert recordings of a first code on a product to position data in a coordinate system, to convert recordings of a second code to input data, and to process the position data on the basis of the input data. The input data may define one or more functional areas in the coordinate system, and the pen may map the position data against the input data and take appropriate action if the position data is deemed to fall within a functional area. This allows the pen to be dynamically provided with a description of all or parts of the functional layout of a product, thereby reducing the need of the pen to pre-store such descriptions for all products. Encryption or usage may also be controlled based on data encoded by the second code. The product may be generated, via a computer-implemented method, to include the first code, the second code and any supporting graphics. The input data may alternatively be derived from another import interface of the pen, such as a communications interface or a replaceable memory unit.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Patent Application No. 60 / 617193, filed October 12, 2004, Swedish Patent Application No. 0501520-1, filed June 30, 2005, and U.S. Provisional Patent Application No. 05, 2005 Priority to Application No. 60 / 695,851, all of which are hereby incorporated by reference. technical field [0003] The present invention relates to a method and system for providing security to position data recorded by an electronic pen. Background technique [0004] The applicant of the present invention has developed a system architecture in which a product with a writing surface equipped with a position code is used. In such a system, an electronic pen, also called a digital device, is used to write on the writing surface while being able to record the position of the position-encoded surface. The electronic pen detects the position code through the sensor, and calculates the position corresponding to...

Problems solved by technology

[0011] A drawback of this type of system is that if the ASH associated with the location of a particular area of ​​the location-coding pattern wants the pen to encrypt the location data with a specific encryption key in order to configure security services in the system, an intermediary server of the type described above is required interaction to configure the corresponding management rules with that encryption key
