Abstract
The present invention relates to a method, a system and a computer-readable medium storing computer-executable components for authenticating a digital pen. The invention is based on the idea that a paper look-up server issues an authentication receipt used by a service handler to authenticate a digital pen. The authentication receipt comprises such information that the service handler can use it to authenticate the digital pen without having to communicate with the paper look-up server.
Claims43
A method for authenticating a digital pen at a service handler in a system including at least one paper look-up server, at least one digital pen and at least one service handler, the method including the steps of:
- sending encrypted data and a digital pen identifier from said digital pen to said paper look-up server, said encrypted data including position data obtained by using said digital pen to read a position code from a surface of a position-coded product;
- identifying at said paper look-up server, based on said position data, a service handler that provides a service associated with said position-coded product;
- authenticating said digital pen and creating an authentication receipt at said paper look-up server;
- sending an indication of the identified service handler and said authentication receipt from said paper look-up server to said digital pen;
- sending said authentication receipt from said digital pen to said identified service handler;
- and
- authenticating said digital pen at said identified service handler based on the received authentication receipt thereby allowing said identified service handler to provide a service associated with said position-coded product.
A system for authentication including:
- at least one digital pen;
- at least one paper look-up server;
- and
- at least one service handler, wherein
- said digital pen is arranged to send encrypted data, including position data obtained by using said digital pen to read a position code from a surface of a position-coded product, and a digital pen identifier to said paper look-up server, receive an authentication receipt from said paper look-up server and send said authentication receipt to said service handler;
- said paper look-up server is arranged to authenticate said digital pen, create said authentication receipt, identify, based on said position data, a service handler that provides a service associated with said position-coded product, and send an indication of the identified service handler and said authentication receipt to said digital pen;
- and
- said identified service handler is arranged to authenticate said digital pen based on the received authentication receipt thereby allowing said identified service handler to provide a service associated with said position-coded product.
