UBIQUITOUS CODE AND INFORMATION SYSTEM USING UBIQUITOUS CODE

摘要

PURPOSE: An information system using a ubiquitous code extensible in temporal and spatial axes is provided to obtain information of the ubiquitous code through an input device to which the ubiquitous code is attached. CONSTITUTION: Information of a ubiquitous code(500) is inputted through a recognition device including a scanner or a camera. The ubiquitous code information is expressed in a PC(Personal Computer)(510). The value of the ubiquitous code is transmitted to a lower server(520). The lower server decides permitted code in which the value of the ubiquitous code is allowed. If the authentication is required, the lower server demands authentication of the ubiquitous code server(530). The code value of the ubiquitous code is registered in the ubiquitous code server. An authentication contents server offers the information to be interactive with the certificate contents server.
