Other objects, features and advantages of the present invention will become apparent from the following detailed description of embodiments taken in conjunction with the accompanying drawings.

Hereinafter, an anti-piracy disk according to the present invention will be described with reference to the accompanying drawings.

1A is a diagram for explaining an illegal copy protection disk according to the first embodiment of the present invention.

As illustrated in FIG. 1, the anti-piracy disk according to the first embodiment of the present invention includes a data layer (eg, poly-carbonate) for storing at least one program such as software, music, video, games, and the like. Layer) 1, a reflective layer 3 for protecting the disk, and a sensor layer 2 formed in a predetermined region of the data layer 1 below the reflective layer 3.

That is, in the anti-piracy disk according to the first embodiment of the present invention, the sensor layer 2 is further formed on a conventional CD or DVD.

In the data layer 1, in the case of a program CD and a DVD, copy protection software is additionally configured in addition to a program (for example, an operating system, Excel, PowerPoint, etc.). Of course, it can be applied to the music, video, game, etc. mentioned above.

The copy protection software of the data layer 1 controls the program to be copied when the program of the program CD, DVD is copied to the HDD of the computing means to be moved to an empty space (for example, a sector) of a specific area of the HDD. By using the location information (sector number) of the specific area of the moved HDD and the identification number (Serial number) of the HDD itself as a sector database (DB), it is controlled to be stored separately in the free space of the HDD and also for each sector database (DB). It also recognizes and controls its own position.

In addition, the present invention copy protection software controls the program stored in the HDD to move to the same location (sector number) when copying to another location (CD, DVD, HDD), in this case it is determined whether the identification number of the HDD is also the same to be copied. To do this, the program is controlled to move to the same sector position by referring to the sector database (DB) when attempting to copy the program of the HDD, and to separately store a control program for determining whether the identification number of the HDD is the same, or for each sector itself. Recognition and, if necessary, copy protection software may be stored together in a separate space on the HDD to take over the control program.

In addition, when controlling the program to be copied is moved to the empty space of the HDD, in the sensor layer 2, the location information (sector number) of a specific area of the HDD and the identification number of the HDD itself are stored in the empty space of the HDD. In addition to storing it separately, it is also hidden in the sensor layer 2 of the CD or DVD.

For example, in the sensor layer 2, a separate memory space (not shown) is provided so that the copy protection software controlling copying is moved to an empty space of the HDD and the location information of the specific area of the sector and the HDD. The self identification number is recognized by the sensor layer 2 and controlled to be stored in the separate memory space of the sensor layer 2 of the CD or DVD as well as the HDD. To this end, a separate memory is configured in the sensor chip 2 to be linked with the copy protection software. In addition, S / W itself performs the same function as above.

At this time, the description about the lacquer protective layer, the silk printing layer, etc. which are normally formed on the reflective layer 3 is abbreviate | omitted.

As described above, the sensor layer 2 is basically comprised between the data layer 1 and the reflective layer 3 (preferably on the data layer 1), and detects the copy attempt from the computing means ( Detect CD or DVD images, detect copying software behavior (attempting to clear the lock), detect differences in rotational speed of CDs or DVDs, or light sources (e.g. laser beam intensity differences (APC, OPC) Power change, etc.) may be a sensor programmed to destroy itself.

The sensor layer 2 is also made of a transparent or translucent material through which a light source (for example, a laser beam) of a CD-ROM or a DVD-ROM can be transmitted.

The sensor layer 2 also detects the temperature of the disk (difference in intensity of the light source (laser beam)), speed (difference in rotational speed), wavelength, etc., or recognizes floating images for CD or DVD copying or other copying software. When the operation exceeds the predetermined threshold value (to be described in detail later), the heat is generated at a set temperature, and in response to the heat generation result, the color of the light transmitting material, which is a material constituting the sensor layer 2, is opaque. It is formed of a material having a composition that changes to one color.

To this end, as described above, when the sensor layer 2 is initially formed in the data layer 1, the CD or DVD ROM laser has a thickness that penetrates the sensor layer 2 during normal CD or DVD operation. It is composed of transparent or semi-transparent material, but after detecting the illegal copy and the sensor layer 2 is heated to the set temperature and the material characteristic is changed to an opaque color, the thickness of the CD or DVD ROM laser should not be transmitted. do.

For example, CD or DVD duplication is detected (detects disc temperature (due to laser beam intensity), wavelength difference, rotational speed difference, etc.), recognizes floating image for CD or DVD duplication, and attempts other duplication. Software motion detection) forms a material (e.g., photochromic, etc.) having the property of changing to an opaque material in response thereto.

Thus, the sensor layer 2 composed of the sensor will be described in more detail.

First, the sensor is a device for converting a change in the physical quantity of the measurement object into a usable electric signal, and converts an input signal of light (illuminance, luminous intensity, color, light displacement, ultraviolet rays, infrared rays) into an electrical signal and outputs the electrical signal.

When the sensor layer 2 applied in the present invention is configured as a sensor, it basically senses light for reading data of a CD or DVD, and at this time, an optical conduction effect (a device whose resistance value changes due to incident light) or a photovoltaic effect By using the principle of (PN junction, light incident on semiconductor and metal junction surface, electromotive force is generated), it is possible to execute the program by detecting the temperature (difference of laser beam intensity), rotation speed, wavelength, etc. of disk for illegal copy attempt. It allows you to distinguish between duplications or to detect duplication attempts (opening CD, DVD images, or other duplication software behavior (attempts to clear the lock)) from computing means.

The sensing capability of the sensor layer 2 may be Si, Ge, GaAs, Se, CdS, Sb ₂ S ₃ , PbO, Se, ZnO, etc. according to the characteristics of the material. MEMS: Micro Electron Mechanical System In this case, in general, in the case of using a general semiconductor application technology, the size of the sensor layer may be formed in a size of 1 mm to several mm.

For reference, MEMS is a technology that integrates a three-dimensional microstructure, circuit, sensor layer and actuator on a silicon substrate, and is a small, complex, and highly operated system based on the structure technology of semiconductor integrated circuits such as electronic, mechanical, optical, and materials. It is a micro-family technology that combines various technologies, and it is possible to miniaturize, integrate, low power, and low cost, and it is possible to manufacture sensor layers ranging from 1 μm to several hundred μm.

In another embodiment, a fuse (not shown) is added to the sensor layer 2 so that if a detection result exceeds a predetermined threshold (described in detail later), the fuse embedded in the sensor layer 2 is destroyed. Depending on the destruction result can be converted into an opaque material.

By detecting the temperature (difference in laser beam intensity), rotation speed, wavelength, image copying, and other copying software operation, the sensor layer 2 generates heat or photoelectricity due to the destruction of the fuse. The color of the sensor layer 2 may be changed into an opaque color due to the heat generated by the conversion, thereby preventing the data (program) stored in the disc of the discolored portion from being read, thereby preventing illegal copying. At this time, if the user inadvertently attempts to copy the disk and destroys it without intention of illegal copying, if the user receives a certain cost and compensates it with a new CD or DVD, the user can install the program without incurring the special burden of inadvertently destroying the disk. Purchased CDs and DVDs.

In this case, in the case of the program CD, it is usually required to store the data on the hard disk of the computing means, so that the sensor layer 2 is programmed so as not to destroy the fuse when the copy attempt is made only for a set number of times (for example, once or twice). .

1B is a diagram for explaining an illegal copy protection disk according to the second embodiment of the present invention.

As illustrated in FIG. 1, the anti-piracy disk according to the second embodiment of the present invention includes a data layer (eg, poly-carbonate) for storing at least one program such as software, music, video, or game. Layer) 1, a reflective layer 3 for protecting the disk, and an anti-copy material layer 5 formed in a predetermined area of the data layer 1 below the reflective layer 3.

In the anti-piracy disk in the second embodiment of the present invention, an anti-copy material layer 5 is further formed on a conventional CD or DVD.

In the data layer 1, in the case of a program CD and a DVD, copy protection software is additionally configured in addition to a program (for example, an operating system, Excel, PowerPoint, etc.). Of course, the same applies to music, video, and games mentioned above.

This copy protection software controls a program to be copied when a program of a program CD or DVD is copied to an HDD of a computing means, to be moved to an empty space (for example, a sector) of a specific area of the HDD. The location information (sector number) of the HDD and the identification number (Serial number) of the HDD itself are controlled to be stored separately in the empty space of the HDD by using the sector database (DB), and each sector database (DB) recognizes its own location by itself. And control.

In addition, the present invention copy protection software controls the program stored in the HDD to move to the same location (sector number) when copying to another location (CD, DVD, HDD), in this case it is determined whether the identification number of the HDD is also the same to be copied. For this purpose, the control program is controlled to move to the same sector positions by referring to the sector database (DB) when attempting to duplicate the program of the HDD, and to separately store a control program for determining whether the identification number of the HDD is the same, or to recognize each sector by itself. If necessary, copy protection software can be stored together in a separate space on the HDD to take over the control program.

At this time, the description about the lacquer protective layer, the silk printing layer, etc. which are normally formed on the reflective layer 3 is abbreviate | omitted.

As described above, the copy protection material layer 5 is basically comprised between the data layer 1 and the reflective layer 3 (preferably on the data layer 1), and is shown in the replicating manner in the computing means. The material specificity is changed depending on the temperature of the disk of the disk or the intensity difference (for example, the power change of the APC, OPC, etc.) of the light source (for example, the laser beam) for replication applied to the anti-copy material layer 5.

Such a copy protection material layer 5 of the second embodiment of the present invention is composed of a transparent or translucent material through which a light source (for example, a laser beam) of a CD-ROM or a DVD-ROM can be transmitted. When a copying attempt is detected according to (APC, OPC power change, etc.), it is formed from a transparent or semitransparent material that can transmit light to an opaque color that cannot transmit light.

To this end, when the anti-copy material layer 5 is initially formed on the data layer 1, the light source of the CD-ROM or DVD-ROM passes through the anti-copy material layer 5 during normal CD or DVD operation. After the material properties are changed from the transparent or translucent color to the opaque color, the light source of the CD ROM or the DVD ROM must have a thickness that does not penetrate the opaque copy preventing material layer 5.

Such a copy preventing material layer 5 is formed of, for example, photochromic or the like. At this time, the copy protection material layer 5 is formed of a material according to the power change of APC, OPC and the like. This is also an independent copy protection technique.

Of course, the anti-copy material layer 5 may be formed to have the same size as that of the data layer 1.

2 is a diagram for explaining an illegal copy protection disk according to a third embodiment of the present invention.

As shown in FIG. 2, the anti-piracy disk according to the third embodiment of the present invention is a data layer (for example, a polycarbonate layer) for storing software, programs such as music, video, games, and the like. (1), an unauthorized copy prevention layer 4 made of a material for preventing unauthorized copying, a reflective layer 3 for protecting the disk, and a predetermined region of the unauthorized copying prevention layer 4 under the reflective layer 3 It comprises a sensor layer 2 formed in the. For reference, in the anti-piracy disk according to the second embodiment of the present invention, the sensor layer 2 is formed on a conventional CD or DVD, and the data layer 1 and the reflective layer 3 are formed in the first embodiment of the present invention. An unauthorized copy protection layer 4 is further formed on the data layer, and copy protection software is added to the data layer 1 or the unauthorized copy protection layer 4 in the case of program CDs and DVDs. Of course, the sensor layer 2 may be formed on the data layer 1 between the data layer 1 and the anti-repudiation layer 4.

That is, in the anti-piracy disk according to the third embodiment of the present invention, the sensor layer 2 and the unauthorized copy prevention layer 4 are further formed on a conventional CD or DVD.

This copy protection software controls a program to be copied when a program of a program CD or DVD is copied to an HDD of a computing means, to be moved to an empty space (for example, a sector) of a specific area of the HDD. The location information (sector number) of the HDD and the identification number (Serial number) of the HDD itself as a sector database (DB) to control to be stored separately in the empty space of the HDD or to recognize and control the location information for each sector by itself.

In addition, the present invention copy protection software controls the program stored in the HDD to move to the same location (sector number) when copying to another location (CD, DVD, HDD), in this case it is determined whether the identification number of the HDD is also the same to be copied. For this purpose, the program is controlled to move to the same sector positions by referring to the sector database (DB) when attempting to copy the program of the HDD. If necessary, copy protection software may be stored together in a separate space on the HDD to take over the control program.

In addition, when controlling the program to be copied is moved to the empty space of the HDD, in the sensor layer 2, the location information (sector number) of the specific area of the HDD and the identification number (Serial number) of the HDD itself are stored in the empty space of the HDD. In addition to storing it separately, it hides it on a CD or DVD. For example, in the sensor layer 2, a separate memory space (not shown) is provided so that the copy protection software controlling copying is moved to an empty space of the HDD and the location information of the specific area of the sector and the HDD. The self identification number is recognized by the sensor layer 2 and controlled to be stored in the separate memory space of the sensor layer of the CD or DVD as well as the HDD. To this end, a separate memory is configured in the sensor chip 2 to be linked with the copy protection software.

At this time, the description about the lacquer protective layer, the silk printing layer, etc. which are normally formed on the reflective layer 3 is abbreviate | omitted.

In addition, the sensor layer 2 and the copy protection layer 4 may be made of a light transmissive material or a semi-transparent material that can transmit light of a CD-ROM or a DVD-ROM, among which a sensor layer 2 ) Is similar to the sensor layer 2 of the first embodiment of the present invention. However, when detecting illegal copying or the like, photoelectric conversion or a fuse built in the sensor layer 2 is destroyed, so that the sensor layer ( 2) It heats itself, and in response to the heat generation result, the color of the stepless copy prevention layer 4 in the region adjacent to the sensor layer 2 changes to an opaque color. In addition, the sensor layer 2 according to the third embodiment of the present invention is composed of an opaque material, if the thickness of the CD-ROM or DVD-ROM can be transmitted even if it is made of an opaque material that is not a light transmitting material or a transparent material. Can be.

In addition, the stepless copying prevention layer 4 is a material having a property that the light transmitting material or translucent material is changed to an opaque material independently in response to heat generation (change in power of APC, OPC) above a certain temperature (eg, photochromic ( It is formed of a material such as photochromic, etc.) and should be composed of a thickness that cannot transmit light when converted into an opaque material. At this time, it detects the power change (difference in beam intensity) of APC and OPC during replication, and the material layer discolors, so that light does not penetrate.

As such, the sensor layer 2 detects the temperature of the disk (depending on the difference in the intensity of the laser beam), the rotation speed of the disk, the wavelength applied to the disk, and the like. As the heat generated by the heat generation or the fuse is broken, the unauthorized copy protection layer 4 around the sensor layer 2 is discolored to an opaque color and thus the disc itself cannot be read, thereby preventing illegal copying. At this time, if the user inadvertently intentionally copies without paying a certain fee and compensates it with a new CD, DVD, etc., the user will be able to purchase the CD and DVD incorporating the program without any particular burden.

In this case, in the case of the program CD, it is usually required to store the data on the hard disk of the computing means. Therefore, the program layer is programmed so that the fuse is not destroyed when the copy attempt is made only for a set number of times (for example, once or twice). .

3 is a flowchart for explaining a method for preventing illegal copying according to the first embodiment of the present invention.

The first embodiment of the present invention is for explaining a method of preventing duplication of music, video, game CD, DVD, and the like.

In the anti-piracy method according to the first embodiment of the present invention, the CD-ROM or DVD-ROM of the computing means recognizes the loading of the disk, and determines whether there is an execution command for the program embedded in the disk (S10, S11). .

If the determination result (S11) is executed, it is executed (S12).

However, if not executed, it is determined whether the copy (S13). At this time, the sensor layer in the CD or DVD determines this, and detects the temperature of the disc (laser beam intensity difference), the rotation speed of the disc, the wavelength, and the like to distinguish program execution from copying or to attempt copying from a computing means (CD To detect DVD behavior or other copy attempts (such as attempting to unlock the lock).

If the determination result (S13) is a copy, it is determined whether the threshold value is exceeded (S14). In other words, even if the user makes a copy by mistake, the user recognizes that the CD or DVD is destroyed during illegal copying and checks the time to perform the copy stop.

When the determination result (S14) exceeds the threshold value, the sensor layer of the disk is invented by photoelectric conversion or the fuse destruction of the sensor layer is executed (S15). At this time, when the fuse is broken, the sensor layer is allowed to generate a predetermined temperature or more.

As a result, the material layer of the sensor layer itself (transmission of light or semi-transparent material to opaque material) or the property of the material layer (an unauthorized copying layer) adjacent to the sensor layer may be changed so that the transparent layer discolors into an opaque layer. (S16). This will be recognized as a bad sector on the disk.

Therefore, the disc is destroyed in its characteristic (S17) and the copy fails.

4 is a flowchart for explaining a method for preventing illegal copying according to a second embodiment of the present invention.

The second embodiment of the present invention is for explaining a method of preventing duplication of a program CD, DVD or the like.

In the anti-piracy method according to the second embodiment of the present invention, first, the loading of a disc is recognized in a CD-ROM or a DVD-ROM of a computing means, and it is determined whether there is an execution command for a program stored in the disc (S20, S21). ).

If the determination result (S21) is executed, it is executed (S22).

However, if not executed, it is determined whether the copy (S23). In this case, the sensor layer in the CD and DVD determines this, and detects the temperature, speed, wavelength, etc. of the disc to distinguish program execution from copying, or attempts to copy from a computing means (floating CD, DVD images, etc.). It attempts to detect the behavior of the software (attempt to clear the lock) when attempting to copy.

If the determination result (S23) is a copy, it is determined whether the threshold value is exceeded (S24). In other words, even if the user makes a copy by mistake, the user recognizes that the CD or DVD is destroyed during illegal copying and checks the time to perform the copy stop.

If the determination result (S24) exceeds the threshold value, the sensor layer of the program disk determines whether the attempt within the set number of times (S25).

If the determination result (S25) within the set number of times the copy is allowed (S26). At this time, for example, the program CD is copied to the hard disk of the computing means.

The program CD copy to the hard disk causes the copy protection software in the disk to move the program copied to the HDD to an empty space (for example, a sector) of the HDD, and the location information of the moved specific area and the identification number of the HDD. (Serial number) as a sector database (DB) so that it is stored in any empty space (sector) of the HDD to move to the same empty space (sector) during duplication, and at this time to recognize the identification number of the HDD (S27) .

However, in the determination result (S25), if the set number of times is exceeded, the color of the sensor layer of the disk is converted into an opaque color. It is discolored (S28).

Therefore, the disk is destroyed (S29) and the copy fails.

5 is a flowchart for explaining an illegal copy prevention method according to a third embodiment of the present invention.

The third embodiment of the present invention is a flowchart for explaining a copy protection method of a program copied to a hard disk in the second embodiment of the present invention.

First, when the program copy command of the HDD is performed in the computing means (S30), it is determined whether the copy command for the copy protection program (S31).

If not, the copy is executed (S34).

However, the determination result (S31), if correct, recognizes the storage location and identification number of the program stored in its own HDD, so as to be moved to the same location (sector) as the location of the object to be copied (CD, DVD, HDD, Internet) At this time, check the HDD identification number (S32).

It can be moved to the same position as its own, it is determined whether the identification number of the HDD is the same (S33) and display the result to an output device such as a monitor of the computing means.

The result of the judgment is not the same, so no copy is performed. More strictly speaking, when copying to CD and DVD, HDD sector numbers do not match, and copying is not possible due to different HDD identification numbers.

In the case of a blank (formatted) HDD, copying is impossible because the HDD identification number is different, and copying is executed only for HDDs in which certain data is already stored because the sectors to be moved cannot be the same. There is no choice but copying is impossible due to different HDD identification numbers.

In the anti-piracy disk and the anti-piracy method according to the present invention described above has the following effects.

First, illegal copying of software, games, and music CDs can be prevented.

Second, by protecting copyrights in the software, game, and music CD sectors, the industry in this field can be nurtured and protected.

Third, rather than copying illegally to users of software, games, and music CDs, it is possible to induce the use of genuine software.

Fourth, it can be useful when applied to the fields requiring illegal copy protection of government, national institutions, research institutes, etc.

Fifth, privacy can be protected through indiscriminate circulation of pornography.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
