As shown in FIG. 2, the first recording medium 110 is an optical disc-type recording medium having a predetermined diameter. The first recording medium 110 may provide information by an optical method, ie, an optical device drive (ODD). An optical drive medium that can record and play back. In the present embodiment, the first recording medium 110 is the UMD described above, and the optical disk drive is a device provided in the aforementioned PSP. The UMD is a read-only type that cannot be changed by the PSP, and information including a large capacity and high quality data 111 and a loading check program 112 is recorded.

The data 111 includes copyrighted multimedia information, and the multimedia information selectively includes text, still images, video, music, and game information.

The loading check program 120 is inserted and recorded in a predetermined recording area of the first recording medium 110. Specifically, the loading check program 120 is preferably inserted and recorded in the data recording area, but is not limited thereto. In addition, the loading check program 120 includes a loading time count module, a loading time comparison module, an illegal copy determination module, and an execution stop module.

Here, the loading time count module is a module that executes a process of calculating a loading time value by counting the loading time of the data, and the loading time comparison module uses the calculated loading time value as a range of an authentication time value. And a piracy determination module, wherein the piracy determination module is a module that executes a process of determining the data as piracy when the counted loading time value is out of a range of the authentication time value. The execution stop module is a module that executes a process of stopping the display of the illegally copied data.

In the loading time module according to the present invention, the authentication time value is a factor for determining whether the loaded data 111 is genuine, and will be described later with respect to the user terminal and the first recording medium 110 loaded by the user terminal. Determined by physical properties. That is, when the first recording medium 110 containing the data 111 is inserted and driven in a specific user terminal, the first recording medium 110 is physically rotated by the optical disk driving means of the specific user terminal. The specific user terminal irradiates light on the first recording medium 110 to load the data 111. At this time, the loading time value of the data 111 is calculated, and the calculated loading time value is defined as an authentication time value. In addition, the loading time value is an average calculated value by multiple data loading. In addition, it is obvious that the allowable error range may be included in the authentication time value by defining the average calculation range by the multiple times of loading as the allowable error range.

In the present invention, the information recorded on the first recording medium can be copied to the second recording medium, which will be described below with reference to FIG.

As shown in FIG. 3, the second recording medium 120 is a memory card type recording medium based on a nonvolatile flash memory, and is a card capable of recording and reproducing information by an electronic or electronic method. It is a medium. In the present embodiment, the second recording medium 120 is a memory stick, and the memory stick is a type in which recording units are divided into sectors and recording change is possible by an electronic or electronic method. In addition, the loading speed of the second recording medium 120 is determined by electric and electronic properties, not physical properties, and is faster than the loading speed of the first recording medium 110.

Specifically, the loading time of the data recorded on the first recording medium 110 and the loading time of the data recorded on the second recording medium 120 show a significant difference due to the physical characteristics of the recording medium. The explanation is as follows. In this embodiment, the loading times of the first and second recording media 110 and 120 are calculated based on the loading times of the UMD and the memory stick.

Data size First recording medium Second recording medium 9 MB About 13 seconds Less than 5 seconds 12 MB About 12 seconds Less than 5 seconds

As can be seen from Table 1, the loading time of the first recording medium 110 is more than twice as long as the loading time of the second recording medium 120. Specifically, the first recording medium 110 is loaded by the optical means of the optical disk drive, while the second recording medium 120 is loaded by the electrical and electronic means without physical driving means, so that the first recording medium is loaded. It is loaded faster than the loading time of the medium 110.

The second recording medium 120 is capable of copying information of the first recording medium 110, and the information can be obtained on-line or off-line. In this case, the copied information includes copyrighted data 111 and a loading check program 112 inserted into the data 111.

The above-described first recording medium or second recording medium is loaded and executed by the user terminal. A schematic structure of the user terminal will be described below with reference to FIG. 4.

As shown in FIG. 4, the user terminal includes an interface unit 220, a memory unit 230, a key input unit 240, and a display unit 250 controlled by the controller 210.

The interface unit 220 is connected to the controller 210 to interface a digital signal driven by the first recording medium 110 or the second recording medium 120. Here, the interfacing means of the first recording medium 110 is an optical disk drive, and the interfacing means of the second recording medium 120 is a card slot.

The memory unit 230 is connected to the controller 210 to store an operating system 231, a main program 232, and a database 233 for controlling the interfaced digital signal.

The key input unit 240 is connected to the control unit 210 to receive a digital signal by the input means. Here, the input means is preferably at least one selected from a button, joystick, keypad or keyboard.

The display unit 250 is connected to the control unit 210 to display a digital signal.

By the configuration of the user terminal described above, the data of the first recording medium 110 or the second recording medium 120 is loaded and displayed. At this time, if the data recorded on the second recording medium 120 is the same as the data recorded on the first recording medium 110, the loading check program inserted in the data is executed, with reference to Figs. The process of the loading check program will be described below.

At this time, the loading check program inserted in the data is automatically executed. Specifically, the loading time count module, the loading time comparison module, the illegal copy determination module, and the execution stop module included in the loading check program are sequentially executed.

After the step S120, the load time count module calculates a load time value by counting the time from the start of loading of the data to the end of the loading (S130).

After the step S130, the loading time value calculated by the loading time comparison module and the authentication time value is compared (S140). In this case, the authentication time value is a preset value and is an average calculation value of the loading time for the genuine product authentication data. In this case, it is apparent that the genuine data is data recorded on the first recording medium 110. In addition, it is preferable that the authentication time value includes a tolerance range, thereby preventing malfunction of the data execution.

After the step S140, whether the illegal copy is determined by the illegal copy determining module, will be described with reference to FIGS. 6 and 7 as follows.

As shown in Fig. 6, when the calculated loading time value L coincides with an authentication time value C ± α including an allowable error range, the data is determined as genuine authentication data. On the other hand, as shown in FIG. 7, if the calculated loading time value I does not match the authentication time value C ± α including an allowable error range, the data is determined as illegal copy data (S150). .

After the step S150, the activation data is normally executed and displayed through the user terminal. On the other hand, for the data determined to be illegal copy data, an appropriate error message is displayed by the execution stop module, or execution of the illegal copy data is stopped.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
