<P>PROBLEM TO BE SOLVED: To provide network service technology capable of reversely integrating the duplicates of contents which are gradually increased in a user device. <P>SOLUTION: The upload type information distribution system is provided with a contents storage part, a retrieval part, a registration part, and a data distribution part. The contents storage part has a function for storing contents. At the time of receiving a contents deposit procedure from a user, the retrieval part inquires whether the same contents exist in the contents storage part or not. When the same contents do not exist, the registration part stores contents uploaded from the user in the contents storage part and registers the user as a contents depositor. When the same contents exist, the registration part additionally registers the user as a depositor of the same contents. The data distribution part distributes the contents stored in the contents storage part to the user registered as the depositor. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
