Embodiment Construction

[0028] Referring to the accompanying drawings, preferred embodiments of the present invention are described below.

[0029] [First preferred embodiment]

[0030] figure 1 It is a block diagram showing the structure of the device for generating and distributing digital content information in the digital content data generating system based on the first preferred embodiment of the present invention. In this embodiment, an example will be described in which movie software (digital content information) desired by the user is obtained (or purchased) through an information terminal installed in a store or other locations. In this case, movie software such as movies is obtained (or purchased) through an information terminal installed in a store or the like.

[0031] refer to figure 1 , a content storage server 6 and a content delivery server 7 are connected to an information communication network 8 . And, one or more information terminals 10 are connected to the information commu...

Abstract

A system for preventing unauthorized use of digital contents information which disables the use of a storage medium having digital contents recorded thereon by those other than an authorized user. An information terminal 10 reads out digital contents information desired by a user from a contents storing server 6 for storing digital contents information, encodes the read out digital contents information based on ID information of a player 15, and writes it on a predetermined storage medium. The player 15 reads out the data from the storage medium and performs a decode process on the data based on its own ID information to restore the digital contents information.

Description

technical field [0001] The present invention relates to a digital content data generation system, and more particularly to a digital content data generation system that restricts use of digital content information copied for a specific user by users other than specified (authorized) users. Background technique [0002] In recent years, with the advancement of computer technology and the popularization of the Internet, there are more and more opportunities to buy products online. Also, video and music data, which are generally analog information, are now being distributed in the form of digital data storage media such as CDs. It is expected that a method of purchasing such digital data (contents) including video and music data via a network such as the Internet and downloading it locally to a digital storage device will become popular in the future. [0003] Although such digital content is provided to the user in the form of a storage medium, usually such as a CD, what is s...
