This is a piracy search module that can be executed or replayed only when it is matched. It prevents illegal copying by inducing original use by blocking the use of illegally copied products in original works.

When you install or save an asset on other storage media such as a user's computer hard disk or other hardware, the product serial number of the storage medium is searched for and updated to save the product serial number stored in the asset. This is a piracy search module that searches and compares the product serial number and executes only when it matches. It prevents backup or illegal copy of the hard disk.

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

1 shows a flow of a method for storing digital data of a predetermined format on a recording medium according to the present invention, and FIG. 2 is a block diagram of a configuration of an apparatus for storing digital data of a predetermined format on a recording medium according to the present invention. It is shown.

The information reading unit 200 reads the information unique to the recording medium from the recording medium (step 100), and the data inserting unit 210 includes the information unique to the recording medium in the digital data (step 110). The recording unit 220 records and stores the digital data on the recording medium (step 120).

In this case, the recording medium includes a CD type, a digital versatile disc (DVD) type, a magneto-optical (MO) disc, and the like. Read more about Readable Compact Discs (CD-ROM), Recordable Compact Discs (CD-R), Rewritable Compact Discs (CD-RW), Readable DVD Discs (DVD-ROM), Rewritable DVD Discs (DVD- RW), MO (MO) disk, zip disk, hard disk (HDD) or floppy disk (FD).

The recording medium may be a readable compact disc (CD-ROM), a recordable compact disc (CD-R), a rewritable compact disc (CD-RW), a readable DVD disc (DVD-ROM), a rewritable DVD disc ( In the case of a DVD-RW) or an (MO) disc, the information specific to the recording medium includes at least a product serial number stored in a portion of each disc, and the recording medium is a hard disk (HDD) or a floppy disk (FD). In this case, the information unique to the recording medium preferably includes at least a serial number assigned to each disk by an operating system in an initialization process for using the disk in a predetermined operating system.

Storage media, which are recording media storing copyrighted works or digital data, include CDs, DVDs, MOs, HDDs, FDs, and the like. In the case of recording media or parts of storage media, such as CDs, producers assign product serial numbers for various reasons, such as identifying the type of product and the amount of production. The product serial number is recorded on the innermost part of the disc. Read the CD using a device such as a regular CD-RW drive, and you can easily find the values. At this time, where the serial number is recorded, the attributes of the disc (for example, CD speed, manufacturer, etc.) are further recorded. In addition, whenever a new recording medium is developed, contents necessary for the recording medium may be added.

Therefore, the information including the product serial number is unique to the recording medium. At this time, for example, the product serial number may determine the unique information of the recording medium, or the unique information may be obtained by adding the name of the company that manufactured the product. Alternatively, a separate code, for example, a code for encryption may be generated based on the product serial number and determined as unique information on the recording medium. As a result, the information unique to the recording medium or the result of processing the information is unique to the recording medium and cannot be obtained from other recording media.

Works composed of digital data, such as application software, image data storing movies, sound source data storing music data, still image data containing photographic or graphic data, and text data containing plain text In order to distribute copyrighted works, it is necessary to store them on a recording medium which is a storage means except for transmitting them through a communication network such as the Internet.

At this time, the information reading unit 200 reads information unique to the recording medium recorded on the disk which is the recording medium (step 100). The data insertion unit 210 processes the information unique to the recording medium as it is or appropriately, for example, combining a product serial number with the manufacturer's name or all the information corresponding to the disk as described above. Create and insert into a portion of the copyrighted work of digital data to be distributed (step 110).

At this time, the inherent information of the inserted recording medium should not be disturbed when digital data that is the original work is used or reproduced. Therefore, the information unique to such a recording medium needs to be inserted into a file header part determined according to a standard or type of standardized file format of digital data. Alternatively, the format of the digital data may be determined using a separate file format including information unique to the recording medium.

When recording the digital data including the information unique to the recording medium on the recording medium in step 120, it is preferable to encrypt and record a part of the digital data according to a predetermined method. This will be mentioned again when describing the method of FIG. 4.

The recording unit 220 stores the digital data generated by the data inserting unit 210 on the recording medium (step 120). As a result, the work, which is digital data including information unique to the recording medium, is recorded on the recording medium.

In this case, the present invention can be applied as it is even if only one recording is possible, such as a CD-ROM or a DVD-ROM. In this case, the inconvenience of the case where the product-specific information is different for each disc will be described later.

If the recording medium is HDD or FD, in order to use the disk, the disk must be formatted according to the file system of the operating system (OS) used in the computer. At initialization, each disk is assigned a serial number, which is recorded on the disk. This serial number is information unique to the HDD or FD recording medium. For example, in MS-DOS or Windows 9X series operating systems, a single number is called a volume serial number. In addition, the name of the volume used for the disk can be determined by the user.

The data inserting unit 210 may include the serial number at least (it may further include the name of the volume) and insert it into the digital data as the unique information on the recording medium.

As a result of the operation as described above, the disc, which is a recording medium, is stored with the copyrighted work, which is digital data containing a value representing information unique to the recording medium.

3 is a flow chart of a method for transferring the digital data from a first recording medium in which digital data of a predetermined format is recorded, the information of which is inherent in the recording medium on which data is recorded, to a second recording medium, according to the present invention. It is.

The method reads the information unique to the first recording medium from the first recording medium (step 300), reads the information specific to the recording medium on which the digital data is recorded from the digital data (step 310), and the information read in step 300. If the information read in step 310 is the same, part or all of the digital data is transferred to a second recording medium and recorded in a predetermined method (step 320).

FIG. 4 shows a flow of a method of transferring the digital data from the first recording medium on which the digital data of a predetermined format is recorded, including information specific to the recording medium on which the data is recorded, to the second recording medium according to the present invention. It is. 5 shows in block form the configuration of an apparatus for implementing the method of FIG. 4 further embodies the method of FIG. 5 can also be used as is to implement the method of FIG.

According to the method of FIG. 1, the first recording medium is recorded in a work in which unique information of the recording medium is digital data. Therefore, the first recording medium may include information about the first recording medium specific information that can be read from a portion or a specific track of the recording medium, and a recording medium in which the work, which is digital data that can be obtained from the work that is digital data recorded on the first recording medium, is recorded. Information is included.

The information reading unit 500 reads information unique to the first recording medium from the first recording medium (steps 300 and 400). If the first recording medium is a disc such as a CD or DVD, the track of the first cabinet may be read to obtain unique recording medium information. If the first recording medium is an HDD, the recording medium unique information may be obtained from the volume serial number of the HDD. You will be able to get

The information separator 510 reads information unique to the recording medium included in the digital data from the digital data (steps 310 and 410). By reading a piece of copyrighted work that is digital data, it reads the information unique to the recording medium. At this time, the entire work may be read to read the recording medium information. In order to work efficiently, it is necessary to read a part of the copyrighted work as digital data and to predetermine the location of the information contained in the recording medium, and to obtain the information by reading the predetermined part. For example, it would be advantageous in terms of efficiency to record information specific to the recording medium in the header portion of the file containing the copyrighted work.

The information comparison unit 520 determines whether the information read in step 400 and the information read in step 410 are the same.

In the case of a recording medium produced through the process of FIG. 1 through a legal process that is not illegally copied, information unique to the recording medium and information unique to the recording medium included in a work stored in the recording medium are the same. If, by an unknown method, the contents of the recording medium produced through the process of FIG. 1 are illegally copied and stored in another recording medium, the recording medium information included in the copyrighted digital data is illegally copied to another recording medium. This is different from the unique information of. This is because there is only one piece of information unique to the original recording medium.

In the process of FIG. 1, when information is illegally copied, information unique to the recording medium may be inserted into the digital data in order to prevent duplication of the recording medium information included in the data of the copyrighted work with the information of the recording medium to be stored. At this time, a predetermined encryption may be applied. In addition, in step 410, when the unique information of the recording medium is read, the reverse process of the encryption is used to read. This will prevent piracy.

If the information read in step 400 and the information read in step 410 are the same, the information reading unit 500 reads information unique to the second recording medium (steps 320 and 420). The data reconstructing unit 530 reads the digital data recorded on the first recording medium and replaces the information specific to the first recording medium included in the digital data with information unique to the second recording medium read in step 420 (step 430). At this time, it may be possible to enhance the security by encrypting.

The information recording unit 540 transfers and records some or all of the digital data, which is the result of step 430, which includes information specific to the second recording medium, to the second recording medium according to a predetermined method (steps 320 and 440). .

The entire work of digital data may be transferred to a second recording medium, and if necessary, a part of the work of digital data may be transferred to a second recording medium and recorded. For example, when all the copyrighted work is moved, that is, in the case of backup or full copy of the recording medium, all the digital data is transferred and recorded. However, when an asset, which is digital data, is an application, for example, and executes the application, only files necessary for execution, that is, a part of the digital data are stored on a recording medium such as a computer hard disk. Alternatively, when digital data is composed of several files, only a part of the digital data is transferred to another recording medium even if only some files are copied to another recording medium as necessary.

3 or 4 as described above, digital data for preventing illegal copying produced or stored in accordance with the process of FIG. 1 is recorded and stored in another recording medium. That is, the method of FIG. 3 or FIG. 4 is to provide a method of copying illegal copy protected data according to FIG. 1 to another recording medium.

At this time, it is preferable to encrypt and record a part of the digital data according to a predetermined method. Only the portion of the recording medium specific information may be encrypted, or the portion including the portion of the recording medium specific information (for example, the file header portion) may be encrypted and recorded. One is for countermeasures against illegal copying, and the other is for preventing reproduction of works, which are digital data created according to the present invention, through a general method.

For example, if the digital data is an MP3 file, which is one of formats capable of playing music, after making a recording medium which is an original work according to the method of FIG. 1, illegal copying is performed without following the process of FIG. In this case, it is necessary to encrypt a part of the digital data constituting the MP3 file so that the MP3 file according to the present invention is not reproduced in an unauthorized manner. For this purpose, it is desirable to encrypt some of the digital data stored on the record carrier.

1 and 2, the first recording medium or the second recording medium of FIGS. 3 to 5 may be a readable compact disc (CD-ROM), a recordable compact disc (CD-R), or a rewritable compact disc. (CD-RW), readable DVD disc (DVD-ROM), rewritable DVD disc (DVD-RW), MMO (MO) disc, zip disc, hard disc (HDD) or floppy disc (FD) It is preferable to include.

In this case, the first recording medium or the second recording medium may be a readable compact disc (CD-ROM), a recordable compact disc (CD-R), a rewritable compact disc (CD-RW), or a readable DVD disc (DVD- ROM), rewritable DVD-RW or MO (MO) disc, the information unique to the recording medium preferably includes at least a product serial number stored in a portion of each disc, wherein the first recording When the medium or the second recording medium is a hard disk (HDD) or a floppy disk (FD), the information specific to the recording medium is a serial number assigned to each disk by an operating system during an initialization process for using the disk in a predetermined operating system. It is preferable to include at least.

The method according to the invention may be partially modified for ease of production of the chew in large quantities in the method of FIG. 1 and FIGS. 3 and 4. Give an example.

In FIG. 1, a product serial number is used when using information unique to a recording medium. At this time, in the case of mass production of copyrighted works, when producing a disc such as a CD according to the present invention, all of the product serial number (or product information recorded inside the disc including the product serial number) can be produced in the same order. have. Since the serial numbers of the recording media, which are the storage media on which the digital data is to be recorded, are all the same, the unique information on the recording medium is the same, and the result of the digital data into which the recording medium is inserted is the same. You can do it.

Even in this case, since the disc with the unique information is not anywhere else, applying the prevention of illegal copying according to the method of FIGS. 3 and 4 can proceed without any problem.

In addition, the apparatus of FIG. 5 has a function of copying a recording medium protected from illegal copying according to the present invention, and may be a device of a general copying apparatus (FDD, CD-RW drive, DVD-RW drive, etc.).

FIG. 6 illustrates a flow of a method for retrieving and executing or reproducing the digital data in a recording medium in which a predetermined format of digital data including information specific to the recording medium on which data is recorded is recorded according to the present invention. FIG. 7 shows in block form the configuration of an apparatus for implementing the method of FIG. 6.

The information reading unit 700 reads information unique to the recording medium from the recording medium (step 600), and the information separating unit 710 reads information specific to the recording medium included in the digital data from the digital data (610). step). The information comparing unit 720 determines whether the information unique to the recording medium read in step 600 is the same as the information unique to the recording medium read in step 610. If the two pieces of unique information are the same, the data extractor 730 allows the digital data stored in the recording medium to be extracted (step 620). The retrieved digital data will be played or played back according to the data's attributes and the user's choice.

In the case of illegal copying, the unique information of the recording medium read from the recording medium and the unique information of the recording medium recorded in the digital data will be different from each other. In this case, the digital data cannot be withdrawn and therefore cannot be executed or reproduced.

The device of FIG. 7 may be implemented by adding partial components to the device of FIG. 5. Thus, the device of FIGS. 2, 5 and 7 may be implemented in one device as needed. This device will be a device capable of manufacturing, copying and executing for the prevention of illegal copying, and can be easily implemented by those skilled in the art with reference to the above description.

Referring back to the prevention of illegal copy production, search and execution / playback of the copyrighted storage medium according to the present invention shown in FIGS. 1 to 7, first, the product serial number of the storage medium is read and stored in the copyrighted work. . Second, the product serial number of the recording medium storing the copyrighted work is read and compared with the product serial number stored in the copyrighted work. Third, the product serial number is compared with the product serial number of the original storage medium stored in the copyrighted work. There are three functions that cause the asset to run if the numbers match, and not to run if it does not match.

The first function can be owned only by the author or the producer of the work, and the second and third functions can be made publicly available to anyone to use, or the functions can be included in the work. If the functions are included in the work, when storing the digital data in another recording medium in step 320 or 440, it is necessary to ensure that only the remaining digital data is stored in the other recording medium except for the part implementing the above function. Do.

The above functions may be bundled into one program or device as needed, each function may be used separately, or the second and third two functions may be included in one program or device.

In addition, these functions may be used as a software program, or may be configured as a hardware system, a component such as a PLD or an ASIC, embedded in or attached to a device to which the present invention is applied, and used as a function of anti-piracy.

FIG. 8 illustrates an example of combining the methods of FIGS. 1, 3, 4, and 6. In the following description, the expression storage medium is used instead of the expression recording medium.

The user purchases a storage medium storing the copyrighted work, which is digital data produced according to the method of FIG. 1 of the present invention (step 800). The user selects the target asset to install or duplicate the purchased asset (step 805). Next, select whether to install / duplicate or execute (play) the copyrighted work (step 810). In this case, when the asset is executed, the process proceeds to the next step 845. If the asset is installed and duplicated, the storage medium for installing and replicating the asset is designated (step 815).

In the execution process, the product serial number of the original storage medium of the copyrighted work is searched according to the method of FIG. 3 or 4 and compared with the product serial number stored inside the digital data as the copyrighted work (step 820). If the result of the comparison does not match, the installation or duplication is made inoperable (step 825) with the warning of counterfeiting.

If the result of the comparison matches, the installation and the replication are executed (step 830). At this time, as described above, the product serial number of the target storage medium to be duplicated is found, and the product serial number in the work is updated with the product serial number and stored (step 835). This completes installation and replication (step 840). At this time, the product serial number update storage function in the work used in step 835 may be stored without being installed or duplicated. This function is provided for the purpose of not copying pirated works, so it is not necessary after normal copying. Of course, depending on the implementation, this function can be replicated together.

In step 845, the user selects to play or reproduce the copyrighted work or the copyed work. If the product serial number of the storage medium is searched and compared with the product serial number in the asset (step 850), if it does not match, in step 855, the copyrighted work is executed with the warning of illegal copying, and the asset is not executed or regenerated, and the asset is executed if it matches. Or after playback (step 860).

In the process of illegally copying a work created in accordance with the present invention, even if the information unique to the recording medium generated using information including a product serial number or a product serial number is known in advance, Since the product serial number of the original recording medium is stored, it can be compared with the product serial number of the duplicated recording medium. In addition, even if the work stored in a specific hardware such as a user's computer hard disk is backed up or illegally used, the result will be almost the same.

In the above, the method and process for searching illegal copies of copyrighted storage media have been described. Hereinafter, a method of protecting content posted on an Internet site from illegal copying will be described.

Read the Uniform Resource Locator (URL) of the Internet site to register or publish the work, and include information about the URL in the work according to a predetermined method (step 900), and include the work containing the information about the URL to the Internet site Register or post to (step 910).

Once a URL is determined, there is only one such URL worldwide. Therefore, the URL can be used as the information unique to the recording medium as described in Figs. 1 to 8 to prevent illegal duplication. When you include information about a site's URL or URL in a work that you want to post or register on a site on the Internet, you can place the information about the URL or URL in the header of the work.

At this time, the inserted URL information should not be disturbed when the original work is used or reproduced. Therefore, the URL information needs to be inserted into a file header part determined according to a standard or type of standardized file format of digital data constituting the copyrighted work. Alternatively, the format of the digital data may be determined using a separate file format including information unique to the recording medium.

Alternatively, it is preferable to encrypt URL information according to a predetermined method and to record it in a work. This may have the effect of not being able to view the URL arbitrarily, but because of the encrypted URL information, the format of the asset's file is different from the standardized file format, and as a result, the present invention has been applied (including the URL) using other general asset playback programs. This can have the effect of making the work unplayable or unplayable.

In addition, the work including the information on the URL is registered or posted on the Internet site corresponding to the URL information (step 910), and the work created as described above is not posted on another site.

The following describes how to prevent unauthorized use of the work generated through the process of FIG.

FIG. 10 illustrates a flow of a method of accessing a work of a predetermined format including information on a URL of a site to be legally registered and posted through the Internet.
