Figure 4 shows a flow chart in which the digital work 6 is provided to a shop, a shop, and sold to a consumer (buyer) in the present invention.

Various types of digital works are produced by the authors. For example, literary works such as novels, essays, nonfiction, criticisms, periodic and irregular publications, professional magazines, newspapers, leaflets, reference books, test papers, textbooks, etc. For example, record works such as recorded tapes, art works, blueprints, manuals, industrial works such as plays, dances, performance works such as dances, etc. In other words, literature, art, music, video, academic, For example, various works (or digital contents) such as research, education, statistics, analytical information, translations, and computer programs.

In addition, the copyrighted work is processed into a digital work (6) in the form that can be executed and processed in a digital device is commercialized, the digital work (6) is given an authentication code based on the digital work registration data and the encryption process The product is then completed and stored in the database. The encryption may be performed in the shop client (A) (B) ... (n), but it is preferable to process the security when commercialized using the encryption / decryption engine 26 of the digital work management server (4). Do.

In the present invention, the digital work 6 downloaded to the consumer is managed by DRM (Digital Rights Management) technology. The DRM technology prevents illegal distribution and copying of various digital contents such as e-books, music, video, games, software, stock information, and images, and manages the profits generated by copyright-related parties by using such protected contents. Products and services.

Currently, copyright protection technology is divided into "encryption" technology that gives a secret key to a normal user and "watermarking" technology that tracks illegal use by inserting copyright information into content. In addition, a DRM solution has been developed that combines these two technologies.

The superiority of DRM is that it does not disable the content duplication itself, but allows the duplication freely, but charges the fee again even if the copied content is used. For example, if you send an MP3 file purchased by a friend to a friend, there is no problem with the transfer, but you will be charged for using the transferred file, which is convenient in situations where it is impossible to block 100% of the digital content. It is attracting attention as a realistic solution (T2 stage).

The digital work 6 thus produced is stored in a file format in the database 37 of the digital work management server 4. The file has different extensions depending on the expression or processing status of the work, which is well known and should be avoided further. In addition, the digital work 6 is classified and stored in various classification methods (step T3).
