The present invention relates to a content purchase registration and usage fee billing system and method for digital content copyright protection in an information and communication terminal, and more particularly, to a database capable of managing purchase information regarding contents purchased normally online and offline. It is possible to identify whether the digital contents stored in each information communication terminal are illegal or not, and the digital contents purchased by the user can be freely played in the user's information communication terminal, The present invention relates to a system for content purchase registration and usage fee for copyright protection of digital contents in an information and communication terminal, which enables a legal use of a copyrighted work by charging a predetermined fee for reproduction.

Recently, the use of MP3 (MPEG Layer-3), which is rapidly increasing in use, is a digital music file format developed by the Motion Picture Experts Group. It is a technical standard that can compress digital audio data of about the size.

Conventionally, in order to enjoy music recorded as MP3 files, it was necessary to use software for playing MP3 files on a computer or to use a portable MP3 player ('MP3 player'). As a product, it has not only gained sensational popularity in domestic and overseas markets, but also has firmly established itself as an export-focused product of domestic small and medium-sized enterprises. On the other side of this quantitative development, however, it is pointed out that the neglect of copyright protection of copyright holders, neighboring rights holders, record producers, and performers puts the record market into a recession and impedes the development of popular culture. The opposition of copyright holders' groups is also expected to rise.

Under these circumstances, recently, high-tech information communication terminals (collectively, digital devices capable of playing digital contents with communication functions), such as MP3 phones, which have an MP3 player function, have been popular.

First, with reference to FIG. 1, a brief description will be given of a method of downloading music content using a commercially available MP3 phone 1 and a method of downloading music content stored in a computer to the MP3 phone 1.

According to the configuration of the music file download system of the MP3 phone 1 shown in FIG. 1, the MP3 phone 1 is a mobile communication server of the mobile communication company 30 via a relay base station 34 installed throughout the country as well as a mobile phone. 31 is connected wirelessly. The mobile communication server 31 is connected to a plurality of sound source provider servers 51, 52, 53... Through the internet 40 via a router 35, and the mobile communication server 31 is A user of the MP3 phone 1 provides an environment in which the user can search for the desired music and download the music from the music provider servers 51, 52, 53. In this case, the mobile communication company 30 may have its own sound source database in its own system separately from external sound source provider servers 51, 52, 53.

The user of the MP3 phone 1 may download the MP3 file from the music provider servers 51, 52, 53... And store the MP3 file in the MP3 phone 1 or play the music in a streaming manner. At this time, the billing server 32 connected to the mobile communication server 31 charges a service usage fee for music downloaded by the user of the MP3 phone 1, which is included in the charge of the mobile phone of the MP3 phone user do.

On the other hand, the user of the MP3 phone (1), in addition to receiving music files from the music provider through the mobile carrier, and transfers all the music files owned and retained by the illegal or legal path to the MP3 phone (1) You can also play.

Herein, the music file acquired by the user through the illegal path is the music received by accessing the server 62 of the free MP3 provider or the recently popular P2P system server 63 through the Internet 41 in FIG. Files and other MP3 files (4) acquired without paying offline, on the contrary, music files acquired by the user in a legitimate path, on the contrary, are paid and downloaded from the paid content seller 61 through the Internet (41) Refers to a music file extracted from a received music file and a music CD (3) that has already been purchased in a format that can be played on a computer such as MP3, WAV, and WMA.

After all, the user of the MP3 phone connects the MP3 phone 1 to the computer 2 and copies the music files contained in the computer 2 to the MP3 phone 1 so that the MP3 phone 1 is identical to the existing MP3 player. It can be used in a way.

MP3 phones have been evaluated to outperform conventional computers and MP3 players in terms of ease of use of MP3 files.However, MP3 phones are vulnerable in terms of copyright protection because MP3 files stored in personal computers can be transferred and played as they are. .

When the music file is downloaded from the mobile telecommunication company 30 using the MP3 phone 1, the user is charged a fee by the mobile telecommunication company, and a portion of the collected fee is paid to the copyright holders as a royalty fee. There is no problem. However, allowing ordinary users to play MP3 files obtained by downloading them from the Internet without any reasonable price on the MP3 phone without any limitation is encouraging illegal use of copyrighted works and neglecting the protection of copyright holders. Becomes

In particular, copyright-related organizations such as record companies and performers have recently prevented MP3 files that have not been downloaded from mobile carriers, that is, MP3 files that are stored on a user's computer, or degraded. It has caused social waves by requiring compulsory restrictions such as being able to reproduce only a certain amount of time (for example, 72 hours) with the sound quality of about 56kbps or less.

However, in response to such restrictions on the use of copyright holders, the makers of MP3 phones, even if the content downloaded from a computer, paid for the MP3 files extracted from the music CDs that the consumer had already purchased and paid for them on the Internet. The MP3 file is opposed because it is unreasonable to restrict its use.

In addition, since there is no institutional or technical means to identify whether MP3 files in the user's computer are illegal or legal, there is no claim to 'restrict the use of illegal content' claimed by the copyright holders. Has difficulty.

On the other hand, the copyright holders said that if a file transmitted through a general computer cannot be classified as illegal content or legal content, it should be regarded as illegal content so that it can be played for only 72 hours and the sound quality should be less than 64 kbps. Although it has been argued, there is a problem in that even MP3 files which consumers pay and purchase and MP3 files which are converted from music CDs purchased by individuals paying a fair price are disadvantageous of playback.

In addition, given the fact that downloads using MP3 phones are already freely made in Korea, the downloading of music files from a computer to an MP3 phone is completely prohibited or limited to downloads only under deteriorated playback conditions or for a certain period of time. In the case of suddenly restricting the user's rights, such as restricting playback to a player, a strong conflict between the general user of the MP3 phone and the copyright holder cannot be avoided.

Therefore, the best way to resolve these conflicts of interest is to create a culture that respects copyrights rather than to enforce compulsory restrictions, and to make users aware that it is easier to use them legally. will be.

In particular, in the concrete implementation method, users can pay only for the actual use (ie, in proportion to the number of times they have listened to music), rather than charging users with a uniformly expensive royalty. It is necessary to allow files to be freely played and listened to by their MP3 phone or information communication terminal.

The present invention to solve the above problems, by establishing a database that can manage the purchase information about the content purchased normally online and offline to automatically determine what content is normally purchased, by purchasing normally An information and communication terminal that allows users to charge a predetermined fee for use of digital content that is not used and to play the content purchased free of charge without charge for normal purchased content. It is an object of the present invention to provide a content purchase registration and usage fee billing system and a method for copyright protection of digital content.

In order to achieve the above object, the content purchase registration and royalties system for copyright protection of digital content in the information communication terminal provided by the present invention has a function of playing digital content files including MP3 files in addition to a mobile communication function.

And a copyright registration server 71 for checking whether the digital content is registered to the user of the information communication terminal 10 and transmitting the result to the mobile communication server 31.

In addition, in order to achieve the above object, the content purchase registration and fee-for-charge system for copyright protection of digital content in the information communication terminal provided by the present invention has a function of playing digital content files including MP3 files in addition to the mobile communication function. An information communication terminal (10) for retaining personal information of the user and extracting tag information of the content from the stored digital content file; A mobile communication server (31) connected to the information communication terminal (10) by a wireless communication network and receiving tag information of the digital content, personal information of the user, and a mobile communication telephone number from the information communication terminal (10); A wireless content provider server (93) connected to the mobile communication server (31) and transmitting a digital content file to the information communication terminal (10) via the mobile communication server (31); A set of personal identification information and mobile communication telephone numbers of a plurality of digital content buyers who have downloaded digital contents wirelessly from the wireless content seller server 93 and a list of tag information about digital contents registered for each purchaser. Copyright registration database 72; And personal identification information of the digital content purchaser received from the wireless content seller server 93 and a tag of the mobile communication phone number and the digital content respectively connected to the mobile communication server 31 and the wireless content seller server 93. By recording the information in the copyright registration database 72, the purchase registration for the content is performed in the name of the user, and the tag information of the digital content, the personal identification information of the user, and the mobile communication telephone number from the mobile communication server 31. When received, the information is compared with the lists stored in the copyright registration database 72 to check whether the digital content is registered for purchase by the user of the information communication terminal 10, and the result is the mobile communication server 31. Copyright registration server 71 for transmitting to the; is provided.

On the other hand, in order to achieve the above object, the system for content purchase registration and royalties for digital content copyright protection in the information communication terminal provided by the present invention is to provide a digital content file and its content file from the genuine data recording medium 3. A user computer 20 for extracting tag information and receiving personal information and a mobile communication phone number from the user; A copyright registration database 72 in which personal information of a plurality of users, mobile communication telephone numbers, and information on contents registered and purchased for each user are stored; And manages the copyright registration database 72 and records the user's personal information and mobile communication phone number and tag information of the content file transmitted from the user computer 20 in the copyright registration database 72. It is provided with a copyright registration server 71 for registering the purchase of the content in the name of.

And, in order to achieve the above object, the content purchase registration and royalties for digital content protection in the information communication terminal provided by the present invention, (a) a tag from the digital content file stored in the information communication terminal (10) Reading the information and transmitting the information to the mobile communication server 31 together with the user's personal information and the mobile communication phone number; (b) the mobile communication server 31 transmitting the user's personal information, mobile communication phone number and tag information of the digital content to the copyright registration server 71; (c) The copyright registration server 71 compares the user's personal information, mobile communication telephone number and tag information of the digital content with the purchase registration lists previously stored in the copyright registration database 72 to display the digital content. Transmitting a 'pre-registered signal' to the mobile communication server 31 when the purchase is registered to the user, and a 'unregistered signal' to the user if the purchase is not registered; And (d) when the mobile communication server 31 receives the 'unregistered signal' from the copyright registration server 71, charging the user for a fee for playing the digital content.

As described above, in the present invention, an information communication terminal including an MP3 phone (hereinafter, referred to as a 'information communication terminal' for a portable device having a communication function and a digital content reproduction function including an MP3 phone) The institutional and technical device proposed to solve the problem may be called a 'Contents Buying Registration'.

The existing method of preventing illegal content distribution was mainly a method in which a digital rights management (DRM) was applied to the content itself so that only the person who purchased it can use it. However, in the information communication terminal according to the present invention, the content purchase registration and fee-for-charge system for copyright protection of digital content has been directed to the fact that all such copyright protection devices have failed by hacking. Ii) register the purchaser's personal information and mobile phone number in the internet-based copyright registration database (see Figure 72 in Fig. 2) (= 'content purchase registration') when the content is purchased. Registered contents can be freely played by information and communication terminals such as MP3 phones, and iii) billed for use only for contents that have not been purchased.

Since general MP3 players are not connected to a communication network, it is difficult to identify whether they are contents purchased or purchased using an internet-based copyright registration database. However, since mobile phones can always communicate with each other and hacking is difficult due to their characteristics, the purchase of contents such as the present invention is possible. It is possible to charge a royalty based on registration and identification of illegal and legal content.

Content to be registered for content purchase according to the present invention refers to all contents that can be played in an information and communication terminal such as an MP3 phone, and covers all music and video data such as music, movies, and music videos. Hereinafter, the term 'digital content' or 'content' will be used as the concept of collectively managing all music contents, music contents other than MP3, and video contents in MP3 file format.

In addition, in the present invention, a category of content files acquired and registered by a user in a normal manner includes a digital content file downloaded from a server of a mobile communication company by using a user's information communication terminal (eg, an MP3 phone) and a user. Music files or video files of all formats extracted from music CDs and video CDs already purchased and owned, and music files or video files purchased and downloaded from content providers (CP) through the Internet are included.

Fig. 2 is an overall configuration diagram of a content purchase registration and royalties billing system for digital content copyright protection in an information and communication terminal according to the present invention, wherein a genuine data recording medium (eg, CD (3)) acquired by a purchaser in a normal manner. The technical configuration for purchasing and registering information on the genuine content file recorded in the copyright registration database 72 is shown.

In order to register content purchases as 'the content that the user has normally acquired' regarding the contents that the user just purchased, the premise of the buyer's personal information (name, social security number, etc.), the mobile telephone number and the buyer A database should be established to register and manage information on the details of purchased contents.

In addition, the MAC number or host ID of a computer network card is used to prevent a single purchaser from falsely registering their genuine CD as if they were multiple buyers. MAC numbers and host IDs are used to distinguish users because they are assigned differently to computers around the world.

The copyright registration database 72 of FIG. 2 is a database capable of accumulating, managing, and retrieving data relating to such a fact purchase. In Korea, a database such as the copyright registration database 72 of FIG. 2 does not exist yet, but in the future, the copyright management organization 70 that can represent a video business operator, a record producer, a performer, etc., establishes such a database, thereby allowing general users to It is desirable to be able to register the purchase information for the purchased content.

In the computerized system of the copyright management organization 70, a copyright registration server 71 and content purchase registration information that can be connected to the outside by the Internet to process a content purchase registration request and can respond to a request for confirmation of content purchase registration are included. The copyright registration database 72 is installed. The copyright registration database 72 is managed by a copyright registration server 71, and the data accumulated therein is stored in a plurality of buyers' personal information (name, social security number, etc.), mobile phone numbers, and purchase registrations for each buyer. Information about the contents (title, artist / performer's name, etc.) (see FIG. 7).

With reference to FIG. 2, first, a method of extracting music and video contents from a data recording medium such as a music CD, VCD, DVD, memory card, etc. owned by a purchaser and registering a purchase of contents thereof will be described.

The user can register the contents of the previously stored storage medium by inserting the data recording medium including the CD 3 and the like, into the user computer 20 and operating the purchase registration program. The user computer 20 is connected to the copyright registration server 71 by the Internet. When the user inputs his name and / or resident registration number and mobile communication phone number on the computer 20, the data recording medium 3 is held. Information about the contents of the files extracted from e.g.) (for example, the title of the song, the name of the singer / performer, etc.), the name of the buyer, the social security number, the mobile communication telephone number, and the MAC number are transmitted to the copyright registration server 71. The copyright registration server 71 performs content purchase registration in the format of data as shown in FIG. 7, and then sends a registration approval signal to the user computer 20 to notify that content purchase registration is completed. The user can then freely use this flagged content.

Next, a description will be given of a content purchase registration method in the case of paying a content provider (CP) on the Internet and downloading a content file (see FIG. 9).

The user computer 21 is connected to the content seller server 91 and the Internet 42, and the content seller server 91 is connected to the copyright registration server 71 and the Internet 43. When the user makes a content purchase request through the computer 21 to the content seller server 91, the user inputs a name, a social security number, a mobile communication number, and sends a confirmation signal about the purchase history. The content seller server 91 transmits the content to the user computer 21 after the payment is made, and the name, social security number, mobile phone number and information about the purchased content (for example, a song) to the copyright registration server 71. The title and the name of the singer / performer) are sent to request the content purchase registration (see Fig. 9). At this time, the copyright registration server 71 sends a registration approval signal to the content seller server 91 after completing the content purchase registration by the registration request of the content seller server 91, and the user approves the registration displayed on the computer 21. The message indicates that the content purchase registration has been completed. The user can then freely use this content. Reference numeral 92 in FIG. 2 denotes a content seller database, in which various contents and customer information are stored.

In the present invention, the contents extracted from the data recording medium including the genuine CD 3 or the like previously purchased, or the contents previously downloaded from the content seller server 91 are purchased in order to be registered in the copyright registration database 72. In the registration process, the purchase registration can be smoothly performed only if the copyright registration server 71 has accurate information on the personal information of the buyer and the contents included in the data recording medium such as the CD 3. That is, it should be possible to know who is the owner or content purchaser of the CD 3, what is the title of the content or downloaded content contained in the CD, and who is the singer / performer.

First of all, in any of the above cases, the user's personal information is not a problem since the user directly inputs the computer 20 in the content purchase registration process. When the content is downloaded from the content seller server 91, the content seller server 91 has information about the content and the purchaser's personal information. Therefore, the content seller server 91 is sent to the copyright registration server 71. This is done by providing purchase registration information for buyers.

However, it is difficult for the copyright registration server 71 to grasp the information of the contents stored in the data recording medium such as the previously purchased CD 3. However, when tag information on the contents is included together in a data recording medium such as a CD 3 or when the information is written on the jacket of the CD, the computer 20 tags in the CD content extraction process. The user may directly read the information or input the information directly to the computer 20 in the purchase registration process and send the information to the copyright registration server 71.

However, in the case where the tag information of the content is not included in the data recording medium such as a CD previously purchased or the direct input by the purchaser is not allowed, the computer 20 or the content additional information is provided to identify what the content is. The server 81 should be assisted.

The method for identifying the tag information of the content by the computer 20 is to establish a database of information (title, artist / performer's name, etc.) of the content in the computer 20, and find information on the content in the database to find copyright. It informs the registration server 71.

In addition, the method by the content-added information providing server 81, the content is connected to the copyright registration server 71 to analyze the characteristics of the song songs, etc. to identify the song name of the various content and to provide the additional information of the content accordingly Use additional information server. At this time, the content additional information providing server 81 finds information about the corresponding content from the content additional information database 82 and informs the copyright registration server 71 at the request of the copyright registration server 81.

In more detail, in the present invention, when tag information is not recorded on a data recording medium such as a CD 3, the user computer 20 may extract a feature vector from a portion of the contents file of the CD in a predetermined manner. Extracts and compares the feature vectors with the feature vector data in the database, and finds the content with the matched feature vector, and copyrights the tag information (e.g., song title, artist / performer's name) Can be provided to the registration server 71; In addition, the user computer 20 transmits the contents of a part of the content file extracted from the data recording medium to the content additional information providing server 81, and the content additional information providing server 81 uses the data of the part of the content file. Extracts the feature vector, compares the feature vector data pre-stored in the content-added information database 82, finds the content with the matched feature vector, and adds tag information (e.g., song title, artist / Name of the performer) is transmitted to the copyright registration server 71.

Here, the feature vector data is data or physical data (e.g., sector allocation information for each file on a CD and size information for each file) generated by extracting a feature resulting from a change in melody, time signature, etc. of a music song. Or serial number.

In order to smoothly operate the content purchase registration system according to the present invention, when a content file is extracted from a data recording medium 3 including a CD 3, a function for automatically reading and generating tag information and a purchaser input There is a need for a software for content purchase registration or a website for content purchase registration with the ability to securely handle personal information. Preferably, a mobile communication company or a record company develops and distributes such dedicated software separately or creates a website. Would be nice.

By the above-described content purchase registration system and method of digital contents for an information communication terminal, a user uses a computer 20 or an information communication terminal (MP3 phone) to store in a data recording medium such as a previously purchased CD or the like. The purchase registration for the content file may be completed, and the purchase registration for the content purchased from the content seller or the information communication terminal (MP3 phone) on the Internet may be completed.

3 is a content purchase registration and usage fee charging system for digital content copyright protection in an information communication terminal according to the present invention, the content is automatically played when the information is reproduced in the information communication terminal (MP3 phone) 10; 4A, 4B, and 4C are schematic diagrams showing specific embodiments of a content purchase registration system according to the present invention shown in FIG. 3. to be.

The system configuration shown in Figs. 3 and 4a to 4c reproduces the contents previously registered by the purchaser by their information communication terminal (MP3 phone) 10 after the content purchase registration according to Fig. 2 is made. It is about the case.

Referring to Figure 3, when the buyer tries to play the content (for example, 'pepper dragonfly' of Cho Yong-pil) registered in advance using the information communication terminal (MP3 phone) 10, the information communication terminal ( 10) reads the tag information data of the corresponding content by the tag information extraction module (see reference numeral 17 of FIG. 5) embedded therein and transmits it to the mobile communication server 31 via the relay base station 34. . The tag information is transmitted from the mobile communication server 31 to the copyright registration server 71.

Next, the copyright registration server 71 checks whether the content is a content registered for purchase in the copyright registration database 72, and transmits a 'pre-registration signal' to the mobile communication server 31 when the content is registered for purchase. And, if the content is not registered to purchase transmits a "unregistered signal" to the mobile communication server (31). At this time, the copyright registration server 71 also transmits the information on the content to the mobile communication server (31).

Subsequently, the mobile communication server 31 transmits the approval signal to the information communication terminal (MP3 phone) 10 when receiving the 'registered signal', and the fee-for-use server 33 when receiving the 'unregistered signal'. Requests a royalty fee and sends an approval signal to the information communication terminal (MP3 phone) 10.

The fee for use server 33 charges the content fee to the purchaser of the information communication terminal (MP3 phone), but only for the actual use of the content purchase registration system according to the present invention (ie, in proportion to the number of times of playback). It is advisable to pay a fee and set the fee for the reproduction of a song so that it is not too high. This is because the burden of paying the fee for using MP3 files that are not registered to purchase contents should not be greater than the purchase of records or purchase of MP3 players, so that users of information and communication terminals (MP3 phones) try to obtain illegal MP3 files. This can make you realize that it is much easier to pay and use a little more than to do it.

Finally, the information communication terminal (MP3 phone) 10 displays the approval signal received from the mobile communication server 31, receives and displays the information on the content, and reproduces the content.

Summarizing the features of the purchase registration system for content to be played in the information communication terminal (MP3 phone) according to the present invention shown in Figs. 2 and 3, the content itself can be distributed free of charge, and the content can be legally purchased. Only one person can purchase and register songs in the copyright registration database 72 for free using an information communication terminal (MP3 phone), and anyone who downloads other contents (illegal or free content) can use an information communication terminal (MP3). Whenever you listen to a song on a phone, you can say that you pay the proper fee.

FIG. 4A shows a configuration in which an information communication terminal (MP3 phone) 10 checks and requests a purchase registration whenever content is played. That is, as described with reference to FIG. 3, each time a content (song) is played in the information communication terminal (MP3 phone) 10, the tag information for the content is transmitted to the mobile communication server 31 and the copyright registration server ( 71) and the content addition information providing server 81, and accordingly, the request for confirmation and approval of the purchase registration is made.

However, the method of confirming the purchase registration and charging of the content every time the content is played in this manner increases the traffic between the information communication terminal (MP3 phone) 10 and the mobile communication server 31 unnecessarily, thereby increasing the total mobile communication. There is a possibility of burdening the system.

In order to solve such a problem, as shown in FIGS. 4B and 4C, the contents purchase registration is transmitted by transmitting the content reproduction history from the information communication terminal (MP3 phone) 10 to the mobile communication server 31 at predetermined intervals or time periods. This can be done by checking and requesting royalties.

Referring to FIG. 4B, the information communication terminal (MP3 phone) 10 reproduces the contents desired by the buyer without going through the confirmation of the purchase of the content purchase and the billing procedure, and each playback in the memory 182 (see FIG. 5). The tag information of the contents and the value of counting the number of times of playback are stored. Then, after a certain period of time (for example, one day, one week, one month, etc.) or a predetermined time (for example, every day of the month), the tag information and the number of times of reproduction stored in the memory 182 are stored. 31) to withdraw the content information, confirm whether or not the content purchase registration and request the fee for use. In this case, the mobile communication server 31 may notify the information communication terminal (MP3 phone) 10 of the fee for use together with the approval signal of the purchase registration.

The configuration shown in FIG. 4C is the same as the principle of FIG. 4B. However, the memory 182 of the information communication terminal (MP3 phone) 10 has insufficient capacity to store tag information and the number of playback values. In contrast, when the memory 182 is full, the contents playback contents (tag information and the number of playback values) stored therein are transmitted to the mobile communication server 31, and later, the mobile communication server 31 performs a predetermined procedure to register the content purchase. There is a difference in that it allows you to make a confirmation and request a royalty. That is, the mobile communication server 31 transfers and stores the content reproduction history data of the information communication terminal (MP3 phone) 10 and confirms and approves whether to register the content purchase at a predetermined period or at a predetermined time.

In addition, even if the user deletes the contents of his or her information communication terminal (MP3 phone), the tag information and the number of playback values must be retained by the information communication terminal until the confirmation of content purchase registration and the usage fee are completed.

Fig. 5 is a block diagram of an information communication terminal (MP3 phone) 10 used in a content purchase registration and royalties billing system for digital content copyright protection in an information communication terminal according to the present invention.

Referring to FIG. 5, the information communication terminal (MP3 phone) 10 has a function of reproducing computer content files including an MP3 file in addition to a mobile communication function, and includes a control unit 11, a transceiver 12, a key input unit 13 ), A display section 14, a call processing section 15, an MP3 playback section 16, a tag information extraction module 17, a memory 18, a microphone 19a and a speaker 19b.

On the other hand, since all other components of the information communication terminal (MP3 phone) 10 shown in Figure 5 are all known, a detailed description thereof will be omitted.

6 is a flow chart of a content purchase registration and usage fee billing method for digital content copyright protection in an information communication terminal according to the present invention. When the user has downloaded the content from the mobile communication company to the information communication terminal (MP3 phone) 10, the content can be registered to purchase through the wireless content seller server 93 (step S103), otherwise the user Determining whether the purchaser of a genuine CD (step S102), in the case of a genuine CD purchaser to extract some data of the content to the personal computer 20 to the content additional information providing server 81 through the copyright registration server 71 (S104 step). Subsequently, the content additional information providing server 81 generates a feature vector using some data of the content (step S105), and compares the feature vector with feature vectors stored in the content additional information database 82. The content is found and tag information on the content is extracted (step S106). Next, the copyright registration server 71 receives the tag information on the content from the content additional information providing server 82, along with the received tag information, the buyer's personal information (name, social security number) and mobile communication phone The purchase registration for the digital content is completed in the name of the user by recording the number and the MAC number (or host ID) of the user computer 20 in the copyright registration database 72 (step S107).

On the other hand, if the user purchased the content from the content seller on the Internet without purchasing a genuine CD, the content seller server 91 automatically requests the copyright registration server 71 to register the content purchase (steps S109 and S108). ).

FIG. 7 is an example of the format of content purchase registration data accumulated in the copyright registration database 72 of FIG. In the present invention, as a user's information for purchase registration of contents, a mobile communication phone number is required in addition to a name and a social security number. This is because the basic premise that a user purchases and registers the content freely in his or her telecommunications terminal (MP3 phone) without any additional fee, and is charged when playing in another's telecommunications terminal (MP3 phone). Because it is.

In addition, the user's name and social security number are importantly used to allow the user to change the information on the mobile communication phone number by determining the identity of the user when the user later changes the mobile communication phone number. Preferably, it would be advantageous to include a tool for changing the personal information of the buyer in the copyright registration program so that the buyer can access the copyright registration server 71 to change the mobile communication telephone number of the purchase registered data at once.

Although the CD serial number of the data shown in FIG. 7 is not applicable to currently commercially available music CDs (see "No Curve"), when a unique serial number is assigned to each music CD in the future, as in the case of a computer software CD, It is anticipated that the music songs contained in one CD can be prevented from overlapping content purchase registration with multiple buyers.

In addition, the CD unique number is automatically generated by the purchaser's computer at the time of purchase registration of the CD, and the same number is generated for the same album of the same singer, and becomes a key to find the material later.

In addition, the MAC number is a unique number given to a network card (LAN card) of a computer. Since computers all over the world have different MAC numbers, when a MAC number is registered together with a mobile phone number, a single person has a genuine number. You can use a CD to prevent multiple people from registering at the same time on your computer.

In addition, in recent years, people can own or use separate computers at home, school, or company, and actually have several computers, such as owning a laptop separately. It is desirable to provide about -5 pieces.

8 is a content purchase registration and usage fee billing method for digital content copyright protection of an information and communication terminal according to the present invention, when a content is purchased from a content seller, a buyer purchases information necessary for the content purchase registration to a computer 21. The state of input is shown. The purchaser can access the copyright registration web site for copyright registration, enter personal information once, register, and register an ID and password. If you register your ID and password only once the first time, you can register the CD after logging in without any inconvenience.

After that, the user can check the information input from the monitor 21a for content purchase registration and click the confirm button. In this case, the CD serial number is assumed to be automatically read out by the computer 20 when the serial number is assigned to the music CD in the future, and since the commercial CD has no serial number, this part should be excluded. do. Also, the user may not know that the MAC number is transmitted to the copyright registration server.

9 illustrates a data flow between the user computer 21, the content seller server 91, and the copyright registration server 71 in the process of purchasing and purchasing content. Since it has already been described with reference to FIG. 2, detailed description thereof will be omitted.

10A and 10B are flowcharts illustrating a process of confirming whether a content purchase is registered and requesting a fee for use each time the content is played in the information communication terminal (MP3 phone) according to the present invention. On the other hand, FIG. 11 is a flowchart illustrating a method of collecting contents playback contents for a predetermined period in an information communication terminal (MP3 phone) and transmitting them to the mobile communication server at one time to confirm whether the contents have been registered for purchase and to charge a fee for use (FIG. 4A). To FIG. 4B).

In FIG. 10A, when a user inputs a content playback command to the information communication terminal (MP3 phone) 10 (step S201), the information communication terminal (MP3 phone) 10 checks whether there is tag information on the content. If there is no tag (step S202), the feature vector is extracted with the help of the content-added information providing server 81 (step S203). The feature vector is compared with the feature vectors accumulated in the content additional information database 82 to find content having a matching feature vector, and the additional information of the content is transmitted to the copyright registration server (step S204). If this supplemental information is provided back to the original telecommunication terminal (MP3 phone) 10, the correct supplemental information (e.g., song title, singer / performer's name) for the free content file or illegal content file is added to the new tag. As the information, the digital content file may be stored integrally with each other (step S205).

Next, the copyright registration server 71 checks whether the content is registered in the name of the user of the information communication terminal (MP3 phone) and purchases the content. The content is transmitted to the communication server so that the content can be reproduced without a separate royalty fee (steps S204 and S206). However, if the content is not registered to purchase the content in the name of the user, the user of the information communication terminal charges a separate fee for the reproduction of the content (step S205).

On the other hand, FIG. 10B proceeds in almost the same order as in FIG. 10A, except that step S208 (content playback) of FIG. 10A is advanced to S212. That is, Figure 10a is to be played after the purchase registration confirmation of the content is finished, Figure 10b is to confirm the purchase registration while playing the content once.

FIG. 11 illustrates a purchase registration method of content related to the system configuration shown in FIGS. 4B and 4C, and the information communication terminal (MP3 phone) 10 undergoes a confirmation procedure and a fee for use fee registration procedure for content purchase registration. The contents of the playback history are stored in the memory of the information and communication terminal (MP3 phone) and then sent to the mobile communication server at regular intervals or at certain times. It is transmitted (step S231) to confirm whether the content purchase registration and usage fee is made (step S233).

In order for the content purchase registration system according to the present invention to be effective as described above, the price for actually listening to music should be much cheaper than the cost of purchasing music. Only then do buyers realize that using a telecommunications terminal (MP3 phone) to enjoy music is more reasonable and cheaper than buying a CD to buy all the unwanted music.

In addition, it is very important to make a royalty charge in proportion to the number of times the music is actually heard. It's more reasonable to listen to music you like a lot and pay more, and to pay less for the music you don't want.

By the 'content purchase registration system' proposed in the present invention, when general buyers can listen to music in a convenient way anytime and anywhere by using an information communication terminal (MP3 phone), it is necessary to deliberately illegally collect or collect music. There will be no.

As described above, the present invention proposes a content purchase registration system as a solution to solve the copyright infringement problem of digital contents surrounding high-tech information communication terminals such as MP3 phones, which is a major issue in Korea. It can have the effect of constructing an asset usage system that satisfies all users.

In accordance with the present invention, a method for registering a purchase and requesting a fee for using digital contents on an information communication terminal and an MP3 phone for copyright protection establishes a database that can manage purchase information about contents that have been normally purchased. By automatically determining whether the content is purchased, a fee is charged for each content that has not been purchased normally, and the content purchased normally can be used free of charge without a separate fee. There is an advantage to harmonizing the interests of free use of lovers.
