SECURITY SYSTEM AND METHOD FOR DIGITAL CONTENTS ENABLING USER AUTHENTICATION WITHOUT OBLIGATORY CONSULTATION TO AUTHENTICATION SERVER

摘要

PURPOSE: A security system and a method for digital contents are provided to eliminate an inconvenience to connect to an authentication server at every contents usage by storing an authentication control set and using the set at following contents usages. CONSTITUTION: A security system for digital contents includes a contents producer server(10), a contents provider server(20) and an authentication server(40). The contents producer server generates a producer control set having information for classifying contents to be supplied based on a predetermined service classification criterion. The contents producer server generates and provides contents having the producer control set. When the contents and the contents producer control set are received, the contents provider server conveys the producer control set to the authentication server and provides the service corresponding to the contents. When the contents producer control set is received, the authentication server maps the contents according to the service classification criterion and provides the mapped information when the service classification information is required from a user terminal. The authentication server alternatively provides a user authentication control set having required information when a particular service group is required from the user terminal.
