NOTIFICATION OF ELECTRONIC DOCUMENTS TRANSMITTED ON THE INTERNET {METHOD OF A NOTARIAL ACT OF THE ELECTRICAL DOCUMENTS DELIVERED THROUGH THE INTERNET}

The present invention relates to a notarization method for an electronic document transmitted over the Internet, and more particularly, to a notarization method for giving a fixed date for the transmission of the digital file in the transmission over the Internet.

Copyrights originate from the time of creation, but if the work is not registered, it is difficult to accurately identify the point of occurrence of the copyright, especially in the case of a work such as digital content on a computer, the amount of creation, ease of delivery method, ease of technical modification, etc. Because of this, there is a possibility of infringement more than any other work, and it is necessary to prepare for it. However, it is difficult to actually expect a large number of digital content files to be registered as copyrighted works due to costly and cumbersome procedures.

Therefore, when it is publicly recognized that such a digital content work existed in a certain form at least at a certain point in time, or that a file of some type was transferred between users, it is compared with the date of copyright occurrence and the form of the original work. Easily handled in case of infringement disputes.

In order to be publicly recognized as above, at the present time, you go directly to a notary public office to receive a notary for the case or access a server that notifies the notary service on the Internet, accumulate it in the database of the server, and present evidence in case of dispute. It stays at the stage of use.

As the Internet is popularized, the transmission of digital files in the form of digital files is very common, but the countermeasure is very weak. Conventionally, there is a method of accessing a server through the Internet and storing it in a database, but not only may it be damaged due to an error or hacking of an electronic device, but also the notarized date is notarized when it is transmitted to a specific person through the Internet. Receiving is still a difficult problem.

The present invention is to solve the above problems, when transmitting a digital file through the Internet, etc., is encrypted by a separate notarized server and is confirmed for the electronic document transmitted through the Internet by giving a confirmation date when the transmission is complete Its purpose is to provide a notary method of giving a date.

1 is a configuration diagram of a network system for implementing the present invention;

2 is a flowchart illustrating a notary method according to the present invention;

3 is a flowchart illustrating a process of confirming a confirmation date of a notarized file.

In order to achieve the above object, a notary method for an electronic document transmitted through the Internet according to the present invention, the terminal of the sender to transfer the file and the terminal of the receiver to receive it is connected to a notary web server through the Internet It is run on a network system.

The present invention is characterized in that, when the sender and the receiver connect to a notary web server and input predetermined member information, the notary web server stores the same and transmits a plug-in program to the terminal of the sender and the receiver. If the sender wants to transmit a file to the receiver, the encryption key is received from the notary web server, combined with the file and transmitted to the receiver, and a confirmation date is given when the reception completion signal is transmitted from the receiver terminal. And a second step of storing the same in a database of the notary web server, and when the sender or the receiver wants to confirm a confirmation date, when the file is transmitted to the notary web server using a plug-in program, the notary web server is encrypted. Contrast check the key and issue a certificate if the encryption key matches Are those that consist of a third step.

Here, in the second step, when the sender wants to transmit a file to the receiver, the sender terminal transmits file information and member information to the notary web server and requests an encryption key. When the encryption key is transmitted to the sender terminal, the sender terminal combines the encryption key and the file to be transmitted, and then performs a DRM process and a watermarking process, and the sender terminal accesses the receiver terminal through the Internet. Transmitting a file, and if the reception is completed normally, the receiver terminal transmits a reception completion signal to the notary web server, and the notary web server stores file information, member information, encryption key information, and a confirmation date in a database. It can be done in steps.

In the third step, when the sender or the receiver selects a file for which the confirmation date is to be confirmed, the sender or the receiver terminal transmits a file including an encryption key to the notary web server and the notary web. The server detects a file stored in the database, extracts an encryption key from each file, the notary web server checks the identity by comparing the encryption key extracted from each file, and the encryption key is identical In this case, it may be to issue a certificate containing the date of confirmation, file information, sender and recipient information, and to store it.

In addition, after the reception is normally completed at the receiver terminal in the second step and the notary web server gives and stores a confirmation date, information about the confirmation date of the file is transmitted to the sender and the receiver through an e-mail. It is another feature of the present invention to further include the step of notifying.

Hereinafter, with reference to the accompanying drawings will be described in more detail.

1 is a block diagram of a network system for implementing a notary method according to the present invention.

As shown in Fig. 1, in the network system for implementing the present invention, a file transmitter 10, a file receiver 20, and a notary web server 30 are connected through the Internet, and the notary web server 30 is connected. Comprises a member information database 40, a file information database 50, a watermarking encryption key information database 60, and a notary public information database 70.

The database may include a database 40 for managing member information, a database 50 for storing file information of a content file such as a transmission date of a digital content and a creator over a network, and a file sender wishing to transfer a file. Notarized information database that stores notarized information such as the date of confirmation such that the adoption of the evidence is effective for the illegal determination of illegal use, such as the time of copyright, or the watermarked encryption key information database 60 for watermarking. 70.

The file sender 10 and the file receiver 20 are connected via the Internet, for example, using a terminal such as a personal computer, and the notary web server 30 is also accessible through the Internet. The sender 10 transmits a file through a plug-in program installed in the terminal, and the program is downloaded and installed from the notary web server 30 at the time of membership registration.

When the sender 10 attempts to transfer a file, the file information and member information are transmitted to the notified web server 30 by the plug-in program, and the encryption key is transmitted. The file is combined with the encryption key and transmitted to the terminal of the receiver 20, and the terminal of the receiver receives and stores it, and when the storage is normally completed, transmits the reception completion signal to the notified web server 30.

The notary web server 30 stores all the information necessary for the file transfer process in the database.

The notary method will be described in more detail with reference to FIG. 2.

First, a sender and a receiver who want to receive a service given a fixed date for an electronic document transmitted through the Internet access a notary web server through the Internet (S100).

Next, when the sender and the receiver input predetermined personal information and an annual fee payment method, the notary web server stores the information in a database and performs a membership registration procedure (S110).

Next, when the registration process is completed, the notary web server transmits and installs the plug-in program to the terminal of the sender or the receiver (S120). The plug-in program performs a series of processes for encrypting and transmitting an electronic document created based on various application programs according to the notary method according to the present invention.

Next, when a sender who is a member wants to transmit a file using a terminal on which a plug-in program is installed, file information, for example, a file creation date, a transfer date, and the like, are sent to the web server notified by the plug-in program. The notified web server stores the file information in the file information database and the member information database (S130).

Next, the notary web server transmits a predetermined encryption key to the sender terminal (S140).

Then, the sender terminal inserts the encryption key into the file, and digital rights management (DRM) processing to prevent the alteration, tampering, and forgery of the inserted information so that the inserted information is kept securely and the owner information of the digital file. A digital watermarking process is performed to conceal (S150).

Next, the processed file is transmitted to the notary public information database on the notary web server side and the receiver terminal (S160).

However, the receiver terminal receives the file and stores the file in a storage medium such as a hard disk. When the reception is completed normally, the receiver terminal transmits a reception completion signal to the notary web server (S170).

Next, when the reception is normally completed, the notary web server notifies the sender and the receiver by e-mail of information such as a confirmation date for the file (S180).

Such a series of processes can be used as important evidence in the disputes that will occur in the future, such as to secure the safety and at the same time give a confirmation date in the file transfer over the Internet.

A process for confirming a confirmation date for a file for which transmission is completed will be described in detail with reference to FIG. 3.

As shown in Fig. 3, the sender or receiver who wants to confirm the confirmation date first accesses a notary web server through the Internet using a terminal (S200).

Then, log in by entering the accounting information, for example, ID and password (S210).

Next, select a file to confirm the confirmation date, and transmits it to the notary public web server (S220).

The notarized web server receiving the file extracts the encryption key from the file, and also extracts the encryption key from the corresponding file stored in the database of the notary web server (S230).

Next, the notary web server checks the identity of the extracted encryption key (S240).

If the extracted encryption key is not the same, a message such as, for example, "confirmation date is not determined" is transmitted to the sender or receiver's terminal for output (S260).

If the extracted encryption key is the same, a verification certificate is issued (S250).

After issuing the verification certificate and store it in the database (S270).

As described above, using the notarization method for the electronic document transmitted through the Internet according to the present invention, it is possible to secure the public reliability of the fixed date in the Internet environment, since the fixed date is given online, There is an effect that anyone can secure copyright of digital contents easily with little effort and cost without going through registration process.

Accordingly, in the present invention, when generating a digital file or transmitting a digital file electronically between network users through a wired / wireless network, the sender information, for example, the creation date or the transmission date of the corresponding file, is transmitted to the file creator. After insertion into the digital file, DRM (Digital Right Management) processing to prevent the alteration, alteration and forgery of the inserted information so that the insertion information is secured against the authorized or unauthorized third party, Using digital watermarking process to conceal owner information and other digital technology to control electronic access, it establishes cyber occupancy rights while proving the fact of electronic commerce through digital file on network such as internet. Recognize private property rights in electronic commerce All.

In addition, notarization that transactions or exchanges of digital files have occurred in cyberspace can be legalized for the smooth trade and exchange of digital files, and the use of evidence as evidence for illegal judgment in the case of illegal or illegal use of digital files will result in the use of the Internet. Document exchange can be made more stable.
