Abstract

PURPOSE: A method for selling and renting an electronic document through a piracy proof is provided to enable a user to purchase a book off line, and to prevent an illegal distribution by respectively authorizing the user to use an electronic document in case that the user purchases the electronic document. CONSTITUTION: An electronic document is made from a general book. The electronic document is registered in a database server 2. The database server 2 is interlocked with a web server. A user selects the electronic document on a web site which sells electronic documents and pays for the document. User information and other necessary information of the user are extracted. An encoding generation engine server reads the electronic document. The electronic document is transformed. Information on an encoding key is recorded in a database server 1. The electronic document is transmitted to the web server. The web server transmits the electronic document which the user selects. A download record of the user is recorded in a database server3.

Description

Electronic document sales and lease method make use of reproduction suppression technology

Previously, electronic documents (e-books) were produced in a form of compatible files and sold to users. However, the biggest reason for the lack of generalization and generalization is the lack of direct watermarking technology for the electronic documents and the technical standardization to prevent such duplication. As a result, there was no trust in electronic documents from the copyright holders or publishers, and users could not easily obtain these documents through other illegal distribution channels, so they did not try to purchase them at a financial price. However, in the case of this technology, when a user wants to purchase an electronic document for an electronic document, the user is legally guaranteed to use a legally guaranteed document for each user, and the electronic document itself is encrypted to suppress illegal distribution of the electronic document. I could get rid of the above problems. Also, technical compatibility is not a problem because it is based on document passwords that are commonly applied to existing file structures.

This technology grants the user the right to use the electronic document when the user purchases the electronic document based on the current user information, thereby simultaneously enjoying the effect of buying the book offline and illegally suppressing distribution. Its practical purpose is to make it possible. In addition, this technology allows electronic documents to be sold and leased like an offline book, allowing an individual to present a book to an individual or indirectly lend information to an enterprise. In addition, if it is illegally copied and distributed, it may trace back the path and hold the responsible person to the responsibility for copyright protection. It is a technology based on the minimum compatibility that can be applied.

The second part of the diagram illustrates the flow chart of flow charts, management methods, and sales and leasing of electronic documents.

① E-mail general books from editing files to compatible files

② Register the registration file on DB Server 2 (List on Web Server)

③ DB Server 2 and Web Server interwork

④ The user selects the document and pays it (requires download to server)

⑤ Request transformation into encrypted electronic document

⑥ Extract user's user information and other necessary information (creation of user authentication information code)

⑦ Read electronic document A from the password generation engine server

⑧ Transform and produce electronic document A 'by inserting as document password in electronic document based on encryption key

⑨ Record information about the encryption key in DB server 1.

⑩ Deliver electronic document A 'to web server

Web server sends selected electronic document to user

다운로드 Record user's download record in DB server3

General offline e-books are converted into electronic document files in PDF, DOC, HWP, SWF, EBK, XML, etc. in advance and are registered in DB Server 2. DB server 1 can be linked with the web server so that the electronic document is displayed as a list, users can select and choose. A user who wants to purchase an electronic document then enters a website (e-book sales site) that sells the electronic document, registers and logs in. At this time, when logging in, personal information and payment information, a purchase method, a payment method, and a purchase target are selected in advance. If you select the electronic document you want to buy from this website and make a payment (payment to purchase), the web server sends it from the DB server 2 where the electronic document is registered to the password generation engine server. Automatically collects the personal information, usage information, and other necessary information of the user to make a single encryption key. The encryption key is inserted into the electronic document as a document password to produce an encrypted electronic document. This encryption key is registered in DB server 1, and DB server 1 assists with the task of repurchasing or leasing later. Encrypted electronic documents must be composed of at least 15 ciphers in combination with 24 uppercase and lowercase letters, 16 international symbols, and 10 numeric characters. That's 50 to 15 wins (50 ^ 15 = 5 ^ 15 * 10 ^ 15 = 30,517,578,125 * 1000 trillion) (this would take hundreds of thousands of years if you tried to solve this password with the fastest computer on the planet).

Then, the encrypted generation engine server sends the encrypted electronic document back to the web server, and the web server sends the electronic document back to the user. When the transmission of the electronic document to the user is completed, the web server leaves the record on the DB server 3 to minimize the problem that can occur in the future retransmission. To open the received electronic document, the user opens the dedicated browser (dedicated READER program) downloaded from the web server, logs in like the website, and loads and opens the electronic document to check the encryption key in the electronic document. If it is correct, the document will be opened and if it is incorrect, the document will be closed. (For the user authentication code, the user serial number and personal identification code according to the unique ID and password, the method of purchase, the available time value, other restrictions, server grant code. Even if a user copies and spreads this electronic document through another illegal distribution channel, the information of the spreader remains in the document. Therefore, the DB server 1 and DB server 3 are searched to trace back illegal users. You can search for it. Also, even if you open an illegally distributed electronic document with a general program, there is a document password, so you cannot open the electronic document unless you know the exact password.

The effects of the present invention are as follows. Because this technology is based on existing compatibility, it does not require a separate watermarking technology and can maximize file compatibility for the minimum file size. In addition, various sales and leasing methods are available for users, and the user's right to use electronic documents can be applied individually, and because the user's purchase information is provided for each document, accurate resale is possible. Since illegal distribution channels can be traced back on the basis of personal information, illegal copying can be suppressed. And if you apply this technology, you can expand to not only electronic documents but also pictures, flash files, multimedia files, audio files, video files, MP3, etc. In the end, this approach becomes the basis for less courtship because it allows copyright protection with minimal file structure and compatibility.

In other words, when renting an electronic document, it is possible to lease the electronic document for a certain period of time, and the instant purchase and postpay payment can also be enabled by using the electronic document as a real time payment function. In addition, since the direct information about the user is stored in the DB server and the individual user is given as a serial number like a social security number, even if the user finds out the password, it is impossible to modify it (and also random distribution is impossible).

Claims (3)

① General offline book ⇒ electronic document (pdf / hwp / doc / swf ...) ⇒ save as electronic document A in DB Server 2 ② Register Electronic Document A to DB Server 2⇒ Link electronic document list on the website ③ Select User ⇒ Member Registration ⇒ Login ⇒ Electronic Document and select the electronic document that you want to rent or purchase. ④ The user selects the electronic document A and inputs the payment information on the website ⇒ request for payment processing ⇒ payment processing ⇒ payment approval in connection with the payment processing system. ⑤ Since the user requested the electronic document A, extract the user information from the server equipped with the password generation engine program and generate the user authentication information code. In this case, the user authentication information code is encrypted and the DB server 1 Register to ⑥ encrypt the document itself to insert the code as the "document password" in the electronic document A in the password generation program engine "with the electronic document server ⇒ A 'in strain ⑦ Transfer electronic document A ' from server equipped with password generation engine program to web server ⑧ The web server sends the electronic document A ' to the user (download the electronic document A' from the user's point of view) ⑨ When the transfer is completed for the user, the web server registers the download information in DB server 3. ⑩ The user executes a dedicated browser (dedicated READER PROGRAM) and logs in to open the electronic document A'.At this time, the dedicated browser checks the validity of the user login information by contacting the server. 문서 If document usage time is exceeded, login is incorrect, or the document password is incorrect after opening the document randomly, the electronic document A ' is not opened.
