Apparatus and method for blocking illegal uploading in intermediate server

The present invention relates to an apparatus and method for preventing illegal upload in a relay server, and more particularly, a relay capable of detecting and blocking mass detour upload or digital code forgery using a filtering key generated by a filtering server when a filtering request is made. An apparatus and method for preventing illegal uploading in a server.

Web Hard is an Internet file management system that can secure, store a certain amount of storage space, store, edit, and download documents and files that have been worked on the Internet, and share files with multiple people. Web hard, which is provided by portal sites such as Naver, is a personal type that can create an account (creation of ID) and store its data and download it when needed, so I can't download files other than myself. On the other hand, the shared web hard site is an open shared type where others can download the files I uploaded, and I can download the files uploaded by others, so anyone can download the uploaded files. This shared web hard has evolved into a profitable shared web hard site where members can upload data from registered members, and other uploaded materials can be downloaded for a fee.

However, in a shared web hard, uploading or using an uploaded work such as a movie or music without the permission of the copyright holder while knowing that the uploaded work is illegal is a violation of copyright. Therefore, downloading illegal videos through online service providers was only possible at the risk of future criminal evaluation.

In order to solve this problem, a series of activities are protected by copyright law by sharing web hard service providers with online copyright contractors and providing “partnership contents”. Such 'partnered contents service' is a service that converts illegal contents into copyrighted works protected by copyright law by contract of web hard service provider and copyright holder (manufacturer), and sells them through web hard site. When the content is downloaded for a certain amount, the revenue is distributed to the copyright holder. In other words, when a user uploads illegal content that is illegally distributed, the webhard service user checks the content on the webhard site and displays it as allied contents collectively. You can use it freely. Filtering refers to determining whether the uploaded digital content is a digital asset or not, and an agency that specializes in such filtering is called a filtering company. In order to secure the efficiency and objectivity of filtering algorithms using electronic fingerprints and to reduce the cost of developing and maintaining filtering technology, many web hard service providers use specialized filtering companies. The filtering company determines whether the uploaded content is copyrighted content at the request of the web hard service provider. Therefore, the market size is expanded with the emergence of the legal download market by the provision of the affiliated content, and the number of users of the download service is increasing.

However, in recent years, despite the affiliated content, the billing is not normally processed or a lot of missing content is generated, and a huge damage is caused to the rights holder, and a serious blow is caused to the copyright to be protected. One of the biggest causes of such illegal digital content generation is a detour upload method using a server-to-server FTP method, rather than being uploaded through an upload module of a normal web hard server. Since the bypass upload method is difficult to properly recognize the upload of the digital content of the web hard server, the filtering is not properly performed, even though the affiliated content is downloaded as non-affiliated content, causing enormous damage to the copyright holder.

Recently, copyright holders have decided that the reason for the circumvention upload is not only an illegal uploader but also aiding or acquiring a relay service provider, and has shown a huge penalty for the relay service provider. However, the relay service provider has a financial burden of additional surveillance personnel to block the detour upload, and suffers from the problem that if the real-time monitoring for 24 hours does not detect it properly, all damages must be taken. It is true.

The present invention made as described above will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating the concept of digital content relay service for illegal upload according to the present invention.

1 is a digital content relay system for illegal upload according to an embodiment of the present invention, the upload terminal 100, the download terminal 200, relay server 300, filtering server 400, the owner It may be configured to include a terminal 500.

The upload terminal 100 is a device for performing an upload function (attachment, transmission and registration of a file, etc.) provided by the relay server 300 according to a usage right given to the user, and is typically a personal terminal (PC, mobile phone). , PDA, etc.).

The download terminal 200 is a device for performing a download function (payment, storage of a file, etc.) provided by the relay server 300 according to a user's usage rights, and is typically a personal terminal (PC, mobile phone, PDA). Etc.).

The relay server 300 is provided so that the upload terminal and the download terminal can be connected to each other via wired and wireless Internet to share the file with a plurality of people through all the bulletin boards, messengers, etc. that can upload and download files in an Internet service environment. As a device, it usually refers to P2P or shared web hard. When the digital content is uploaded from the upload terminal 100, the relay server 300 transmits the information and the electronic fingerprint on the digital content to the filtering server 400 and requests a filtering. Information about the transmitted digital content is stored in the relay server 300 DB again, and the electronic fingerprint is used to determine whether the copyrighted work is matched with the electronic fingerprint of the digital copyrighted work. When the relay server 300 receives the filtering result, the selling information, and the filtering key from the filtering server, the relay server 300 adds the filtering key to the uploaded digital content together with the selling information according to the filtering result. For example, if the received filtering result corresponds to a work, uploading is completed by registering and marking as 'partnered content' and adding sales information about the work to the bulletin board. At this time, the download terminal 200 can be downloaded with the payment for the selling price. In addition, by using the filtering key, it is possible to know whether the uploaded digital content is the filtered digital content. The relay server 300 will be described in detail later with reference to FIG. 2.

The filtering server 400 receives digital asset information from the relay server 300 or the rights holder terminal 500 and registers the digital asset as a digital asset. The filtering server 400 generates and stores the filtering key and the electronic fingerprint received from the relay server 300 and the electronic fingerprint of the registered digital work by the filtering request for the digital content uploaded from the upload terminal 100. Compares the same, performs the identity check, and transmits the check result and the filtering key to the relay server 300. At this time, the relay server 300 completes the upload by setting the copyright for the same digital content as the registered digital work and adding the sales information to the affiliated content.

The rights holder terminal 500 relay server 300 or filtering server to prevent the copyright holder owned by the copyright for a specific digital work is copied or distributed without permission through the relay server 300, etc. An apparatus for transmitting digital asset information including at least one of meta information of a digital copyrighted work, original digital content, and an electronic fingerprint, as 400, typically refers to a personal terminal (PC, mobile phone, PDA, etc.). The meta information includes sales information (sale type, sales per use period, billing amount, etc.) along with unique information of a digital work such as a file name, a title, a supervisory name, an actor name, a rating and a screen shot. The electronic fingerprint includes a DNA, a hash value of a digital work.

2 is a diagram showing the configuration of a relay server 300 according to an embodiment of the present invention.

Referring to FIG. 2, the relay server 300 includes an up / download management unit 310, a filtering management unit 320, a relay control unit 330, a settlement unit 340, and a digital content DB 350.

The up / download manager 310 receives the digital content from the upload terminal 100, stores and registers the digital content, and transmits the digital content to the download terminal 100 after payment confirmation. First, when the uploader wants to upload digital content, the upload / download manager 310 provides an upload module to upload the digital content to the upload terminal 100. The upload module includes an input window for inputting information such as title and classification of digital content, and a selection window for specifying and uploading digital content to upload. When the uploader uploads the digital content, the upload / download manager 310 stores the digital content information and the uploader information together with the uploaded digital content in the digital content DB 350. Thereafter, when a download request for digital content is received from the download terminal 200, the up / download management unit 310 transmits the digital content to the download terminal 200 when the payment is completed after checking the payment means and payment.

The filtering management unit 320 extracts an electronic fingerprint of the uploaded digital content, requests filtering from the filtering server 400, receives a filtering result, sales information, and a filtering key from the filtering server 400, thereby receiving the digital content DB 350. ). The extracted electronic fingerprint includes a hash value and DNA. Therefore, each filtering is generated for the hash value and DNA of the electronic fingerprint, and a filtering key is generated every time the filtering occurs. When the filtering is completed with only the hash value, one filtering key is generated, and the filtering is performed with the hash value and the DNA. When this is done, two filtering keys are generated. The filtered digital content is registered in the bulletin board and can be downloaded.

The relay control unit 330 registers the digital content stored in the digital content DB 350 in the uploaded order in the bulletin board, and adds the sales information and the filtering key to the registered digital content according to the filtering result. For example, if the filtering result corresponds to a work, the relay control unit 330 registers and displays digital content as 'partner content' and adds sales information for the work to the bulletin board. In addition, the relay control unit 330 determines whether or not an illegal upload by determining whether a filtering key is added to a post registered in a bulletin board.

The method for determining whether the relay control unit 330 is an illegal upload using a filtering key for digital content registered in a bulletin board is as follows. If the filtering result in the digital content is no-matching and the number of filtering keys is 1, the uploader arbitrarily tampered with the codec and did not recognize the digital content. I think that. That is, when the filtering management unit 320 attempts to extract the DNA for the uploaded digital content but fails to extract the DNA due to the forgery of the codec, the filtering server 400 requests a filtering even if the digital content is not matched. Since no filtering key exists for hash values, there is no filtering key for DNA. As described above, the digital content forgery of the codec is deleted from the bulletin board or blocked in advance so that the relay control unit 330 is no longer downloadable.

In addition, if none of the filtering keys exist in the digital content, the filtering manager 320 does not make a filtering request to the filtering server 400 because the filtering manager 320 is uploaded through a bypass path instead of a normal upload path. I never do that. Such digital content is determined to be a detour upload posted as non-affiliated content despite being affiliated content. As described above, the deferred uploaded digital content is deleted from the bulletin board or blocked in advance so that the relay control unit 330 can no longer be downloaded.

If the number of filtering keys in the digital content is one and the filtering result is a match or the number of filtering keys is two, it is determined that the digital content is normally uploaded. This is a case where the upload is normally performed through the upload module of the relay server 300, the filtering request is made to the filtering server 400, and the filtering server 400 calculates the filtering result through normal filtering. The normal digital content is registered in the bulletin board and can be downloaded.

The settlement unit 340 collects the total number of times and the amount of money downloaded for each digital content registered in the bulletin board and distributes them to the uploader and the copyright holder at a predetermined rate. The settlement process is performed in a predetermined cycle, and the distribution rate is predetermined by a preliminary agreement between the uploader and the copyright holder.

Meanwhile, the work DB 350 stores digital content information, an original file of digital content, an electronic fingerprint, and rights company related information (rights ID, rights name, rights company code, etc.). In addition, digital content information and filtering keys uploaded or downloaded are stored.

3 is a flow chart showing each step of the illegal upload blocking method in the relay server according to an embodiment of the present invention.

If there is a request for uploading the digital content from the upload terminal 100 to the relay server 300, the relay server 300 uploads the digital content (S341). The relay server 300 extracts the electronic fingerprint of the digital content, transmits the digital content information and the extracted electronic fingerprint, and makes a filtering request to the filtering server 400 (S342). When the upload request is received from the relay server 300, the filtering server 400 compares the electronic fingerprint received from the relay server 300 with a pre-stored electronic fingerprint and compares the copyrighted work with the registered digital content. Determine if the file is the same file. Thereafter, the relay server 300 receives the filtering key, the filtering result, and the selling information from the filtering server 400 (S343).

The relay control unit 330 of the relay server 300 determines whether the uploaded digital content is illegal uploading using the received filtering key (S344).

First, when the determination result is 'normal', the number of filtering keys in the digital content is one and the filtering result is matching or the number of filtering keys is two, and the normal content is determined as uploaded digital content. The normal digital content is registered in the bulletin board and can be downloaded (S345).

Next, in the case of “bypass upload”, it is determined that no filtering key exists in the digital content, and the reason for the fault is determined by the service provider. As described above, the deferred uploaded digital content is deleted from the bulletin board or blocked in advance so that the relay control unit 330 can no longer be downloaded (S346).

Next, in the case of 'codec forgery modulation', the filtering result in the digital content is no matching and the number of filtering keys is 1, and the reason for the fault is determined in the uploader. As described above, the digital content forgery of the codec is deleted from the bulletin board or blocked in advance so that the relay control unit 330 is no longer downloadable (S346).

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
