Description
The present invention relates to an electronic document management system for registering and managing an electronic document through a communication network. More particularly, the present invention relates to an electronic document registration environment for uploading, creating, or modifying an electronic document, By registering the requested electronic document as a standard electronic document, the user can use the standard electronic document management service based on the cloud at any time as an author, and insert metadata including a time stamp into the electronic document to be registered, The present invention also relates to an electronic document management system for ensuring uniqueness of a stored electronic document and guaranteeing a license by blocking the registration of a standard electronic document by a non-copyright holder.
The e-book is a digital book in which the content of a work that has been published as a book is recorded as an electronic document using digital data. The electronic book format includes EPUB (electronic pul- bitioning) and PDF / A- 1). EPUB is a technology standard for e-books enacted by the International Digital Publishing Forum (IDPF), and many e-book makers have adopted it, but compared with the PDF / A-1 format, (PDF / A-1) is also used in its own domain.
In order to create such a standard e-book, it is necessary to use an e-book exclusive editor (or program). It is not only costly to prepare and use an editor separately for each author, It was also inefficient because it was difficult to learn how to use it.
Thus, as disclosed in Japanese Patent Application Laid-Open No. 10-2011-0121405, an electronic document management server system which is accessed through a network and provided with an electronic document uploading, editing and downloading service has been proposed. As a standard electronic document A technology was developed that not only manages registration but also distributes it under digital rights management (DRM).
However, since the electronic document management server system is a system in which a plurality of authors independently register and manage their own electronic documents, there arises a problem that non-copyright holders can also register copying, distribution, or normally distributed electronic documents, The damage caused by the distribution of the electronic document registered by the copyright owner can also be drastically increased.
In other words, digital rights management (DRM) is basically a technology that only authorized users can access and view standard electronic documents. It is a technology that allows non-copyright holders to manage standard electronic documents readable or duplicated or leaked, When registering with a server system, it was not developed as a technology to block such registration.
Accordingly, although the server system disclosed in Japanese Patent Application Laid-Open No. 10-2011-0121405 manages the electronic document of the author as a standard electronic document, it does not protect and manage the copyright, I have a problem that I can leave the contention to the user.
In addition, if a public entity such as a military unit establishes a server and registers and manages an electronic document, there are cases where an electronic document is registered in duplicate by different users. At this time, When registered in the operated state, there may be a problem due to cross-talk in contents delivery by reading the electronic document.
Therefore, in the present invention, when a system for registering and managing an electronic document is constructed and used through a communication network, when an electronic document to be distributed, leaked, or reproduced is requested to be registered by a non-copyright holder, And the electronic document management system which manages the electronic document while protecting the rights of the copyright owner without managing the copyright strife.
According to another aspect of the present invention, there is provided an electronic document management system comprising: a database for registering and storing an electronic document in which metadata is inserted and metadata inserted in an electronic document by matching with user account information of a copyright holder; A user connection unit configured to authenticate a user connected through a communication network according to a user account, and to allow a user to independently request registration and download or browse an electronic document; When there is no metadata in the electronic document to be registered, metadata including a time stamp and file attribute information is generated and inserted into the electronic document to be registered, and the registered user is registered as a copyright holder in the database A metadata input unit for storing the metadata; If there is metadata in the electronic document to be registered, if the request for registration is made by the copyright holder, the electronic document requested to be registered is judged as the original document and registered and stored in the database. If the request is a registration by a non- And rejects the registration; .
The registration request of the electronic document includes an upload, and the document verification unit stores the login record of the registration request of the electronic document in the database, and inquires the login record for the copy tracking.
The document verifying unit searches the database for user account information matched with the metadata matching the metadata of the electronic document requested to be registered, and judges the copyright holder as a genuine document if the user who requests registration is the same as the copyright holder. If the user is not the same person And judges that the metadata is identical to the metadata of the electronic document requested to be registered even if the metadata does not exist in the database.
The document verifying unit temporarily stores the electronic document determined as the original in the database for a preset period separately from the electronic document previously stored in the database, and links the electronic document previously stored in the database to download or browse .
Wherein the electronic document to be stored in the database is a standard electronic document of a predetermined format and includes a document conversion unit for converting the electronic document into a standard electronic document of a predetermined format, Converts the metadata into a document, inserts the metadata into the metadata input unit, and stores the metadata in the database.
Wherein the predefined formats are designated as a plurality of standard formats and are converted into a plurality of standard electronic documents in accordance with each format, the user connection unit providing an environment for creating and modifying standard electronic documents of any one of a plurality of formats, The document conversion unit generates a standard electronic document in a different format, and the metadata input unit inserts metadata having the same time stamp into a standard electronic document generated by the user connection unit and the document conversion unit, respectively, and stores the inserted metadata in a database And to download or browse an electronic document in a format supported by a terminal of a user connected through a communication network.
According to the present invention configured as described above, a time stamp indicating a registration time is inserted when registering and storing an electronic document, and when requesting registration of an electronic document in which a time stamp is inserted, a registration request by a non-copyright holder is rejected, So that the user can receive the management service of the electronic document while protecting the copyright.
In addition, the present invention can manage a plurality of authors as a standard electronic document under a cloud environment through a communication network, record and manage registration attempts by a non-copyright holder, and provide traceability data, The copyright protection at a registration time different from that of the DRM may be introduced to strengthen the protection of the rights of the author.
