Copyright management method using digital copyright illegal distribution site search system {Digital rights management method using unlawful websites searching system}

The present invention relates to a copyright management method that protects the rights of digital copyright holders by searching for, warning, and circumventing illegal copying by users who are not permitted to use digital contents to spread through the Internet and networks. In detail, copyright management using digital copyright illegal distribution site search system that automatically detects the usage status of copyrighted materials on the Internet, induces accurate collection of copyright fees, and prevents illegal distribution sites from illegally distributing them anymore. It is about a method.

Today, our society can be summed up as 'Knowledge Information Society', which is developing at a frightening speed thanks to the development of computers, the development of information and communication technology, and the rapid spread of networks. However, with the development of various technologies and the rapid increase of the Internet population, the dysfunction of information is growing rapidly. Informatization dysfunction has been damaging in a variety of ways and ways, from individual damage to individuals, to private and public institutions, and the entire country. Such damages are not only damages but also serious problems in terms of delaying and regressing the speed of development of the knowledge-information society that can develop indefinitely and weakening national competitiveness in the age of infinite competition.

There is an infringement of copyrighted property as a dysfunction of such informationization. Copyright is protected by an exclusive right under the copyright law regarding the use of the work. Therefore, in order to use copyrighted works, in principle the permission of the copyright holder is required unless the free use of the work is recognized under the provisions on the restriction of copyright property rights, or if compensation for the copyright holder is paid or deposited. Unauthorized use of a copyrighted work constitutes a copyright infringement. Nevertheless, there are many cases of unauthorized use of copyrighted works online as well as offline due to immoral marriages.

In the case of works related to computer programs, to check for infringement, check the registered program on the PC used at the workplace or the office with the check disk, and request the authenticity of the searched program and then fail to verify the authenticity. I admit it. However, there is a problem that requires a lot of manpower and time to check whether the software being used for a large number of computers are genuine.

Thus, there is a growing interest in agent-based technologies that can handle the protection and management of effective copyright rights. For example, electronic books and music distributed through various channels such as Digital Rights Management (DRM). There is a need for a technology and a service that securely protects various digital contents such as files, video information, games, software, images, etc. from various illegal copies, and enables the payment of contents services by using such protected contents.

The present invention has been invented in view of the above-described circumstances, and protects digital copyrights by inputting copyright information search terms to be protected, automatically searching for pirate sites using words similar to the search terms, and warning and inheriting them. As an important use in monetization, the purpose of the present invention is to provide a copyright management method using a digital copyright illegal distribution site search system that can prevent illegal copying and protect the commercial value of digital content.

In order to achieve the above object, the present invention provides a novel search method for classification paths and sites that match the search terms by searching the main keywords by classification while navigating websites connected to the Internet using an information collection program in a digital copyright illegal distribution site search system. Storing copyright information in the DRM database, comparing the new copyright information with a list of previously established legitimate sites, and determining whether there is a suspicion of copyright infringement; Storing and analyzing the source of the alleged site's homepage to determine whether it is an illegal site, and if it is determined to be an illegal site, it is classified as a target of infringement litigation if it is determined to be an illegal site twice. Notifying the operator have.

The information collection program is characterized by using a meta search engine.

In addition, the copyright information stored in the DRM database is characterized by storing in the inverse index method.

Hereinafter, the configuration and operation of the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 shows the structure of a search engine according to a preferred embodiment of the present invention.

As shown in the accompanying drawings, the copyright search engine includes an information collection module 11, which is an information collection program for collecting search results of websites connected to the Internet network, and a DRM database using the inverted index technique. An indexer module 13 stored in (12), a query web server module 14 for processing various queries, and a monitor module 15 for checking the query processing results.

As the information collecting module 11, a crawler which is, for example, a meta search engine, is installed as an information collecting program that searches directories of domestic search engine sites and extracts sites including keywords belonging to a copyright DB. The meta search engine may use other search engines that perform homogeneous functions, such as spiders, in addition to crawlers, and such meta search engines may include a plurality of portal sites (eg, Lycos, Hanmir, Catchin, Naver, Simmani, Empas, Alta). Search function that searches the directory information (classification and site summary information belonging to the web site belonging to the selected portal site) among specialized DB search service companies in each field such as Vista as a subject by classification and reconstructs the search results. Because it is equipped with the advantage that you can check the search results at once without having to search for several companies one by one.

The DRM database 12 stores copyright information on a web site search result searched based on the subject matter of each category. The information table of the copyright information includes a web site name, a document name, a name as shown in FIG. It consists of URL, copyright content, categorized keyword, and portal site name. In addition, copyright information as reference data for determining whether the website is searched for or whether it is a legitimate site or a suspected copyright infringement is stored. The information table of the copyright information as the reference data is shown in FIG. As shown in b), it consists of website name, document name, URL, copyright contents, and classification subject words. This is information stored by receiving input from a contracted user.

Next, a process of the indexer module 13 storing the search results of the information collection module 11 in the DRM database 12 using an inverted index technique will be described.

The index consists of a set of words, the location and frequency of word occurrences in each document, and a set of similar words that are mapped through the words. For example, if there are four sentences like "i love you," "god is love," "love is blind," and "blind justice."

blind (3,8); (4,0)

god (2,0)

i (1,0)

is (2,4); (3,5)

justice (4,6)

love (1,2); (2,7); (3,0)

you (1,7)

Here blind is 3, 8 because it starts from the 3rd sentence, and since it starts from the beginning of the 4th sentence, it is indexed as 4.0, and is indexed in the same way as below. When this method is used to find the frequency in which sentence use.

In addition, with respect to similar words, for example, the word "C language" can be mapped to the word "programming language" in the AltaVista portal site, for example in the Yahual portal site, and the user query is made using the mapping relationship of the index index. By reconstructing, we can improve the recall and precision of the query.

The query web server module 14 allows the operator of the system to surf websites to input a keyword for searching for allegedly infringing websites, the selection or input of portal sites to be searched among several portal sites, and the copyright in the relevant field. This function allows you to enter the words you want to inquire about.

That is, the query web server module 14 reconstructs a query for each portal site by using an inverted index list when an operator wants to inquire about copyright by an operator, and then performs an SQL query on the DRM database 12 to generate a result. You will get it. In this process, the result records are ranked in order of the frequency of the documents by word indexed in the inverted index list. Of these, records existing in the appropriate site copyright information table of the DRM database 12 are tagged with "suitable site" and records not otherwise stored in a candidate list presumed to be an illegal site.

The monitor module 15 performs a suitability feedback process for checking whether the actual list of illegal sites is a candidate list suspected of copyright infringement among query results obtained through the query web server module 14. Existing search engines do not include the user's suitability feedback process for such candidate lists. In the present invention, the system operator can re-enter key words of the copyright information, and search whether the entered words appear in documents belonging to the candidate list. This process is performed by the secondary crawler, and the search results are shown as the frequency of occurrence of words searched for documents in the candidate list. Finally, the system operator determines whether the document belonging to the candidate list infringes copyright, and the monitor module 15 provides useful information for this.

3 is a flowchart illustrating an illegal site search method according to an embodiment of the present invention, which will be described with reference to FIGS. 4A to 4D, which are actual search examples.

First, in order to collect information of websites through a crawler that is an information collection module 11, websites are stored in a search.txt file from portal sites. In other words, as a field to be searched, for example, websites having a theme such as "music" or "cartoon" are input to a search word (see FIG. 4A).

The screen as shown in FIG. 4B is output. At this time, check the selection boxes of portal sites to be searched among multiple portal sites and press the OK button.

As a result, it automatically finds a directory of selected search engines and stores related sites in the DRM database 12 to create a meta search engine.

Subsequently, a word to be inquired about copyright is input through a search word input window as shown in FIG. 4C. Entering, for example, CCM here will list sites related to the CCM as shown in FIG. 4D.

Compare the sites included in the list with the legal sites that have been built in advance, and the sites not included in the legal sites are categorized as allegedly infringing sites, and a separate list is created. Sites containing high-risk words are classified and saved as a final candidate list.

Based on this, the source of the homepage is analyzed to determine whether it is copyright infringement and finally determine whether it is an illegal site.

Therefore, if it is determined that it is an offense site, a warning and genealogy notice is given to the corresponding site, and it is separately stored in the DRM database 12, and periodically checked through the monitor module 15 for copyright infringement. If it is extracted again as an illegal site in the future, it is classified and stored as an infringement litigation site so that the operator can take civil and criminal remedies through litigation.

As described above, when the present invention is commercialized and applied to Internet companies, it is possible to protect copyrights on the Internet, thereby inducing revival of the Internet contents business, and confirming the utilization of each work on the Internet in real time. Collecting and analyzing usage patterns can also lead to maximization of corporate profits. The main application fields of the present invention can be directly applied to cultural contents such as movies, music, and cartoons, and can be applied to fields that can utilize the meta search engine technology of this technology as a source technology as another main expected effect. That is, it can be used as a meta search engine in a specialized area such as a women-only meta search engine or a specific content-oriented search engine, and thus, there is an advantage in that it is possible to seek protection for Internet works in a wide range of fields.
