Title:

DISTRIBUTED SERVICE PROCESSING SYSTEM

Document Type and Number:

Japanese Patent JP2005039569

Kind Code:

A

Abstract:

To avoid concentrating process loads of services about providing contents on one station.

An authentication system (2) authenticates the user of a user terminal (6) requesting to provide contents and, if the authenticate result is justifiable, sends authorization information to the user terminal (6). Upon acquisition of the authorization information from the user terminal (6), a cancel information providing system (4) decides whether the authorization information is proper, and, if proper, provides the user terminal (6) with cancel information for canceling a protection process of the contents. Upon acquisition of a contents request from the user terminal (6), a contents providing system (5) provides the user terminal (6) with protection-processed contents.
