BACKGROUND OF THE INVENTION

FIELD OF THE INVENTION

The present invention relates to a method for authenticating information reproduced from a disc type recording medium, a disc player for playing disc type recording media, and a gaming device using information reproduced from a disc type recording medium.

Overview of the state of the art to which this invention relates

In recent years, recording media such as disks storing information recorded in the form of recesses corresponding to a predetermined format find use as main storage media. One of the features of these disc-type recording media is its large storage capacity.

Some recording media such as disks that have found widespread use include an information protection tool that protects the accumulated information from unauthorized copying. Such protected recording media such as disks prevent copying of accumulated information without the consent of the author.

Information from protected media such as discs is played using a special disc player.

Before playing back information from a secure disc-type recording medium, the disc player decides whether to record a predefined code to protect the accumulated information, that is, a security code, on this protected disc-type recording medium. In other words, the disc player reproduces information from the disc-type protected recording medium after confirming that the disc-type protected recording medium is a legal disc. Such a disc playing system is generally known as a protection system.

In order to illegally reproduce information from unprotected recording media such as disks, attempts were made to use a special device that is connected to a disc player.

Previously, it was generally accepted to read a security code recorded in a specific area on a secure disc-type recording medium loaded in a disc player, and thereby confirm the legitimacy of this protected disc-type recording medium. Despite the actual inability to read the data of the security code, the above special device works as if it could read the security code and as a result recognize the recording medium as a disk, the validity of which in reality should not be confirmed.

With the help of the above-mentioned special device, the recording medium obtained as a result of illegal copying of a disc type, the legitimacy of which must not be confirmed, can be recognized as legitimate during the authentication process when playing it and can be played by the disc player to which this special device is connected.

SUMMARY OF THE INVENTION

Therefore, the aim of the present invention is to provide a method of authenticating information that provides reliable detection directly of a recording medium of a disc type, the legitimacy of which cannot be confirmed, or of a special device that may have been connected to a disc player to invalidate a recording medium of a disc type whose legality should not confirmed, thereby preventing the execution of any operations with this recording medium of the disc type, as well as effectively preventing schenie illegal copying of the disc type recording medium to which the law should not be confirmed.

Another objective of the present invention is to provide a disc player having an authentication means for implementing the above information authentication method, which reliably detects directly the recording medium of a disc type, the validity of which does not need to be confirmed, or a special device that may have been connected to the disc player for recognition legal recording medium of a disc type, the validity of which should not be confirmed, thereby preventing the execution of any operations with this recording medium of the disc type, as well as in the effective prevention of illegal copying of the recording medium of the disc type, the legitimacy of which must not be confirmed.

Another objective of the present invention is to provide a gaming device having authentication means for implementing the above information authentication method, which reliably detects directly the recording medium of a disc type, the validity of which cannot be confirmed, or a special device that may have been connected to the disc player for recognition legal recording medium of a disc type, the validity of which should not be confirmed, thereby suppressing the execution of, for example Imer, the program read out from the disc-type recording medium.

The information authentication method according to the present invention includes steps for performing an absolute authentication process for validating a recording medium using authentication information registered on this recording medium at a predetermined position at a predetermined time in accordance with the first rule, and performing the process of arbitrary authentication, carried out to confirm the legality of this recording medium at an arbitrary time in accordance obstacle to the second rule.

DESCRIPTION OF THE PREFERRED EMBODIMENT

A video game device incorporating the principles of an information authentication method, a disc player and a gaming device according to the present invention is described below with reference to FIGS.

The video game device, generally indicated at 10 in FIG. 1, uses a disc-type recording medium, which may be, for example, a rewritable compact disc, a recordable compact disc, a digital video disc, or a write-once disc. This disc type recording medium is hereinafter referred to as an "optical disc".

As shown in figure 1, the video game device 10 has a mechanism for accessing the disk 14, designed to access the optical disk 12 and read various programs and various data from this optical disk 12, as well as the controller of the program 16, designed to receive various programs and various data from this mechanism to access the disk 14 and control the execution of programs in accordance with predefined sequences of processing operations.

The mechanism for accessing the disk 14 has a drive motor 18, designed to rotate the optical disk 12 around its own axis, a drive controller 20 that controls this drive motor 18, and an optical read head 22, which performs optical reading of data recorded on this optical disk 12, and outputting an electrical signal in the range of radio frequencies (radio signal) representing the read data.

This radio signal contains slow frequency modulation data obtained as a result of the oscillatory movement of the grooves and grooves recorded on the optical disk 12 in the radius direction, and the main data (programs and data) represented by the grooves recorded on the optical disk 12.

In addition, the disk access mechanism 14 has a security code detector 24, which provides a security code for authentication from the radio signal generated by the optical read head 22, and a master data demodulator 26, designed to demodulate the radio signal generated by the optical read head 22 and convert this radio signal into the master data.

The mechanism for accessing the disk 14 also includes a controller for playing the disk 28, designed to check the protection code with respect to the predefined code and control the playback mode in accordance with the results of the check, the master data buffer 30, which provides storage of the main data received from the main demodulator data 26, and an interface 32 that exchanges data depending on the type of master data.

The program execution controller 16 has a controller 36 for displaying information related to at least authentication on a display 34.

The optical pickup 22 can be moved along the optical disc 12 in the radius direction using the head drive 38, which is controlled by the head drive controller 40.

The control of the electric drive controller 20, the head drive controller 40, the security code detector 24 and the playback controller of the disc 28 is carried out by the CPU (central processor) 42.

The video game device 10 operates as follows: an optical read head 22 optically reads the data recorded on the optical disc 12, and outputs the resulting data as a radio signal to the circuit system at a later stage. The security code detector 24 detects the security code from the slow frequency modulation data and then checks this security code against a predetermined code. The playback controller of the disc 28 controls the playback mode in accordance with the verification results received from the security code detector 24.

The master data demodulator 26 reads the main data and transmits this master data through the master data buffer 30 and the interface 32 to the program execution controller 16. The program execution controller 16 controls the execution of the program related to these transmitted master data, as well as the display controller 36 for playback images of authentication information on the display 34.

The controller of the electric drive 20 is controlled by the CPU 42 in order to supply power to the motor winding of the drive 18, which drives the optical disk 12. The control of the drive controller of the head 40 using the CPU 42 is carried out in order to enable the optical pickup 22 to be moved by the head drive 38 along the optical disk 12 in the radius direction.

In Fig. 1, the main data is recorded on the optical disk 12 as a series of notches modulated in accordance with, for example, an EFM modulation code (eight-to-fourteen modulation code), which is a digital audio disc modulation scheme.

If the optical disk 12 is a disk obtained through the normal channel (hereinafter referred to as the "legal disk"), then the bits or grooves are subjected to slow (mechanical) frequency modulation in the radius direction in a completely peripheral or separate signal region on the optical disk 12 in accordance with the process modulation with a carrier using a signal with a frequency of 22.05 kHz, in the form without returning to zero.

The optical disk 12 rotates at a predetermined linear speed, for example, the drive motor 18. The drive of the drive motor 18, rotating the optical drive 12, is controlled by the drive controller 20. The drive controller 20 provides power to the winding of the drive drive 18 in accordance with the control signal from CPU 42.

A carrier signal with a frequency of 22.05 kHz is a signal having a frequency of half the sampling frequency (44.1 kHz) for compact discs. The predefined information for authentication, that is, the security code, is repeatedly registered in the TOC region (content table) of the component subjected to slow frequency modulation in the radius direction.

The security code can have data of several bytes and has a code that is common to various devices, an area code indicating the geographical area of playing a legal disk, and a single code assigned individually to each legal disk. If the optical disk 12 is an illegal disk, then there is no record of any security code on this optical disk 12.

The optical pickup 22 detects the radio signal from the optical disk 12, which is rotated by the electric motor of the drive 18, and sends the detected radio signal to the security code detector 24 and the basic data demodulator 26.

The optical pickup 22 moves along the optical disk 12 in the radius direction of the head drive 38. The head drive 38 moves the optical pickup 22 to the desired position in the radius direction of the optical disc 12. The drive of the head 38 is controlled in accordance with a control signal from the CPU 42.

The security code detector 24 is used to detect the security code from the radio signal coming from the optical disk 12. In particular, the security code detector 24 detects a carrier component with a frequency of 22.05 kHz from the radio signal, extracts slow frequency modulation data superimposed on the carrier frequency component, and detects a code from this slow frequency modulation data. The security code detector 24 decides whether the detected code is a security code or not.

The disc playback controller 28 sends a command to start authentication and a command to end authentication to the CPU 42. The CPU 42 controls the detection process performed by the security code detector 24 in accordance with the command to start authentication and controls the security code detector 24 to output the selection result to the controller playing the disc 28, carried out in accordance with the command to complete authentication.

The playback controller of the disc 28 controls the playback of the optical disc 21 in accordance with the control signal from the CPU 42, and the decision by the security code detector 24.

The master data demodulator 26 sends the main data obtained by demodulating the radio signal using EFM modulation to the master data buffer 30. The master data buffer 30 provides temporary storage of the main data and, in response to the control signal from the playback controller of the disc 28, transfers these master data through the interface 32 to the program execution controller 16. If the main data is an audio signal, then the interface 32 outputs this audio signal to the audio output terminal 44.

A program execution controller 16 is used to control program execution. The display controller 36 as part of the program execution controller 16 controls playback of images on the display 34 in certain cases, as described below.

The display 34 includes a screen output device having, for example, a liquid crystal display panel, and provides image reproduction in accordance with the display data obtained by the program execution controller 16.

The security code detector 24 and the playback controller of the disc 28 can be made in the form of independent components, but it is possible to install them as a functional block of the CPU 42.

The characteristic function of the video game device 10 is described below.

The characteristic function of the video game device 10 is to confirm the legitimacy of the optical disc 12, carried out using the authentication information registered on this disc in a predetermined position, at a predetermined time in accordance with the first rule (absolute authentication process), and confirm the legality of the optical disc 12 carried out at any time in accordance with the second rule (the process of random authentication). This function is performed by the authentication means 100 shown in FIG. 2.

The authentication means 100 is described below with reference to FIGS. 2 and 3.

As shown in FIG. 2, the authentication means 100 comprises means for detecting the modulated component 102, means for detecting 104 and means for selecting authentication 106, which are part of the security code detector 24, as well as means for issuing a playback command 108, means for selecting absolute authentication 110, and means for selecting arbitrary authentication 112, which are part of the playback controller of the disc 28. As shown in FIG. 3, the authentication means 100 further comprises means for activating an arbitrary authentic fication 114, program execution means 116, selection means 118 and the authentication signal is forced closure means 120 included in the program execution controller 16.

The modulated component detection means 102 implements the function of demodulating the radio signal S _RF read from the optical disk 12, and as a result, reads data of a slow frequency modulation Dw. The means of detection 104 implements the function of detecting the code Dc registered in the position corresponding to the positional data entered in the first register 130 or the second register 132, carried out from the data obtained by reading the slow frequency modulation. The authentication selector 106 implements a function for deciding whether the detected code Dc matches the security code Ds entered in the register 134 and outputs the selection result.

The means for issuing a command for playing 108 generates a command for playing the optical disk 12 in various positions in the absolute and arbitrary authentication processes supplied to the CPU 42. The means for selecting the absolute authentication 110 is activated by the command for absolute authentication coming from the means for issuing the command for playing 108, and confirms the validity of the selection result received from the authentication selector 106 in accordance with the first rule. The random authentication selector 112 is activated by the random authentication command from the playback command issuing means 108 and confirms the validity of the selection result received from the authentication selector 106 in accordance with the second rule.

The first rule is to declare confirmation of conformity with the norm if the selection result received from the authentication selector 106 matches the norm, and to declare non-confirmation of conformity to the norm if the selection result received from the authentication selector 106 does not correspond to the norm. On the contrary, the second rule is to declare conformity confirmation to the norm if the selection result received from the authentication selector 106 does not correspond to the norm, and to declare non-confirmation of conformity to the norm if the selection result received from the authentication selector 106 matches normal.

In the case of the first access to the optical disk 12, the means for issuing the command to play 108 reads the data of the position of the input entered in the first register 140, and submits the resulting data of the position of the address as a search command in the CPU 42 in accordance with the command received from the CPU 42, in order to complete the absolute authentication process.

The CPU 42 transmits information, for example, the access position data contained in the search command supplied from the playback command issuing means 108 to the head drive controller 40 (see FIG. 1), and generates a trigger signal supplied to the electric drive controller 20. B In accordance with this trigger signal, the electric drive controller 20 supplies power to the winding of the drive motor 18. According to information from the CPU 42, the head drive controller 40 controls the head drive 38, as a result of which th movement is provided by the optical pickup 22 along the optical disk 12 in the radius direction position in the treatment represented the information.

As shown in FIG. 3, a program execution tool 116 implements a function for executing various programs. For example, if the result of the absolute authentication process is confirmation of compliance with the norm, then the program execution tool 116 transmits the main data sent via the interface to the main memory (not shown), and executes the program transferred to this main memory. In addition to this, if the result of the absolute authentication process is confirmation of compliance with the norm, then the program execution means 116 continues to execute the activated program. In addition, the program execution means 116 periodically or temporarily generates a control signal, which is a Sa activation command, which is supplied to the random authentication means 114.

In response to this activation command Sa from the program execution means 116, the random authentication activation means 114 generates an enable signal Sb indicating the start of the arbitrary authentication process and arriving at the means for issuing the playback command 108 shown in FIG. 2.

The authentication signal selector 118 determines the arrival of the authentication signal Sc from the absolute authentication selector 110 or the random authentication selector 112 and generates a signal Sd. indicating the execution / continuation of the program, or signal Se, indicating the forced end of the program.

In particular, if a signal Sc1 is indicated in the means for selecting the authentication signal 118, indicating confirmation of compliance with the norm and received from the absolute authentication selector 110 and the arbitrary authentication selector 112, then the authentication signal selector 118 generates a signal Sd, which is input to the means program execution 116 and indicating the execution / continuation of the program. In the event that an Sc2 signal is transmitted to the authentication signal selector 118, indicating non-confirmation of compliance with the norm and received from the absolute authentication selector 110 and the random authentication selector 112, the authentication signal selector 118 generates a signal Se, which is sent to the forced termination tool 120 and indicating the forced end of the program.

In response to the signal Se indicating a forced termination and coming from the authentication signal selection means 118, the forced termination means 120 generates an interrupt command to the program execution means 116 and forcing the current program to be terminated.

In accordance with the enable signal Sb from the means of activating arbitrary authentication 114 and the command from the CPU 42, the means for issuing the playback command 108 reads the reference position data entered in the second register 142 and provides this reference position data as a search command in the CPU 42 s the purpose of the arbitrary authentication process.

In the process of absolute authentication, the CPU 42 transmits information, for example, the access position data contained in the search command received from the playback command issuing means 108, to the head drive controller 40 (see FIG. 1), and generates a trigger signal supplied to the controller electric drive 20. In accordance with this starting signal, the electric drive controller 20 provides power to the winding of the drive motor 18. In accordance with information from the CPU 42, the head drive controller 40 controls e drive head 38, which ensures the movement of the optical pickup 22 along the optical disk 12 in the direction of the radius to the position of circulation represented by this information.

In the random authentication process, the detection means 104 detects the Dc code registered in the access position in accordance with the positional data (access position data entered in the second register 142) entered in the second register 132.

Since the Dc code detected by the detection means 104 is different from the security code Ds entered in the register 134 connected to the authentication selector 106, the authentication selector 106 outputs a selection result representing a non-confirmation selection.

However, since the random authentication selector 112 generates a signal Sc1 representing the conformity confirmation in accordance with the second rule, if the selection result obtained from the authentication selector 106 is the selection of the non-confirmation of compliance, the program execution controller 16 executes the process corresponding to the norm. That is, the authentication signal selection means 118 generates a signal Sd, which is received by the program execution means 116 and indicating the execution / continuation of the program.

Processing operations performed by the authentication means 100 are described below with reference to FIGS. 4-8.

The authentication means 100 performs the absolute authentication process in step S1 shown in FIG. 4.

The absolute authentication process is described below with reference to FIGS. 5 and 6.

In step S101 shown in FIG. 5, the playback instruction issuing means 108 indicates a predetermined starting position (access position data entered in the first register 140) on the recording track of the optical disc 12 and sends a search command to the CPU 42 and providing a search handling position by optical pickup 22.

Next, in step S102, the playback controller of the disc 28 sends a rotation command to the CPU 42 and providing the operation mode of the CPU 42 with standard speed.

In step S103, the CPU 42 controls the controller of the electric drive 20 to supply power to the motor winding of the drive 18 provided in accordance with the rotation command given in step S102. In addition, the CPU 42 controls the head drive controller 40 in accordance with the search command given in step S101, as a result of which the head drive 38 moves the read optical head 22 along the optical disk 12 in the radius direction until it reaches the initial position indicated by the command to search.

Next, in step S104, the playback controller of the disc 28 instructs the playback in the CPU 42 to reproduce information from the optical disk 12 from the specified initial position. In step S105, the playback controller of the disc 28 instructs the CPU 42 to start authentication.

In step S106, the actual authentication selection process is performed in accordance with a command to start authentication. Figure 6 presents the sequence of processing operations in the authentication selection process.

In the authentication selection process, the modulating component detection means 102 decides whether there is a carrier component with a frequency of 22.05 kHz in the radio signal S _RF obtained by reading from the optical disk 12 made by the optical read head 22 in step S201 shown in FIG. 6.

If there is a carrier component with a frequency of 22.05 kHz in the radio signal S _RF , then control proceeds to step S202. If the component with a carrier frequency of 22.05 kHz in the radio signal S _{RF is} absent, then control proceeds to step S207, in which the selection of non-confirmation of compliance with the norm is announced.

In step S202, the modulation component detection means 102 decides to superimpose the slow frequency modulation component on the carrier frequency component. If the slow frequency modulation component is superimposed on the carrier frequency component, then control proceeds to step S203. If the component of the slow frequency modulation is not superimposed on the component of the carrier frequency, then control proceeds to step S207, in which the selection of non-confirmation of compliance with the norm is announced.

In step S203, the means for detecting the modulated component 102 demodulates the component of the carrier frequency in order to extract the slow frequency modulation component providing data for the slow frequency modulation Dw.

In step S204, the detection means 104 detects the data (code Dc) indicated by the position data of the slow frequency modulation data Dw entered in the first register 130.

In step S205, the authentication selector 106 decides whether the detected code Dc matches the security code Ds entered in the register 134, that is, the decision as to whether the optical disk 12 is a legal disk or not.

If the detected code Dc corresponds to the security code Ds, then control proceeds to step S206, in which the selection of the confirmation of compliance with the norm is announced. If the detected code Dc does not correspond to the security code Ds, then control proceeds to step S207, in which the selection of non-confirmation of compliance with the norm is announced.

Returning to the program shown in FIG. 5, in step S107, the disc playback controller 28 instructs the end of absolute authentication to the CPU 42. In accordance with this command, to end the authentication, the CPU 42 controls the security code detector 24 to output the selection result to the controller disc play 28.

In step S108, the absolute authentication selector 110 makes a decision in accordance with the first rule. If the selection result obtained from the authentication selector 106 indicates the selection of the confirmation of compliance, then control proceeds to step S109, in which the selection of the confirmation of compliance is announced and after which the process of absolute authentication ends.

If the selection result obtained from the authentication selector 106 indicates a non-confirmation selection, then control proceeds to step S110. In step S110, the playback controller of the disc 28 decides whether the optical disc 12 is an audio disc or not in accordance with the data recorded in the TOC area of the optical disc 12.

If the optical disc 12 is not an audio disc, then control proceeds to step S111, in which the non-confirmation of compliance is declared and after which the process of absolute authentication ends.

If it is decided in step S110 that the optical disc 12 is an audio disc, then control proceeds to step S112.

In step S112, the disc playback controller 28 resets the disc playing condition for the optical disc 12 to the audio disc playing mode and reproduces information from this optical disc 12. The audio output terminal 44 shown in FIG. 1 outputs an audio signal, and the absolute authentication process ends . At this stage, the management of the authentication process is terminated and control of the processing mode of the audio signal begins.

Returning to the main program shown in FIG. 4, in step S2, the authentication signal selector 118 decides whether the result of the absolute authentication process is confirmation or non-confirmation of compliance. If the result of the absolute authentication process is confirmation of compliance with the norm, then control proceeds to step S3, in which the authentication signal selection means 118 generates a signal Sd indicating the execution / continuation of the program (in this case, a signal for activating the program) received by the execution means program 116. In response to the signal Sd, the program execution means 116 transfers the main data obtained as a result of reading from the disk access mechanism 14 to the main memory (not by azannuyu).

In step S4, the display controller 36 reproduces an image indicative of conformity with the norm on the screen 50 (see FIG. 9) of the display 34 in accordance with a command from the program execution means 116.

For example, as shown in FIG. 9, the reproduced image includes a game program header 52 read from the optical disc 12, a character string 54 for verification, for example, identifying the number of the optical disc 12, and a license offer 56.

After reproducing this image, control proceeds to step S5, in which the game program, for example, entered in the main memory, is executed.

In step S6, a random authentication process is performed. This arbitrary authentication process is carried out if the program execution means 116 periodically or temporarily generates a control signal, which is a Sa activation command, which is supplied to the arbitrary authentication means 114.

The random authentication process is described below with reference to FIGS. 7 and 8.

First, in step S301, the existing state of the CPU 42 is acquired. The playback controller of the disk 28 controls the playback of the optical disk 12 under the control of the CPU 42. The operation mode of the optical disk 12 under the control of the CPU 42 can thus be changed as a result of the command from the playback controller of the disk 28 to CPU 42.

In particular, in step S301, it is determined that the current state of the CPU 42 corresponds to the read, play, search, error, or rotation of the drive. The processing operation indicated in step S301 is performed if a command is issued to the CPU 42 to acquire the existing state of the CPU 42 from the playback controller of the disc 28.

Next, in step S302, the playback controller of the disc 28 checks the existing state of the CPU 42 acquired in step S301. If the current state of the CPU 42 corresponds to the read, play, or search mode, then the random authentication process ends.

If the current state of the CPU 42 does not correspond to either the read mode, the game mode, or the search mode, then control proceeds to step S303.

In step S303, a decision is made to rotate the drive motor of the drive 18 in accordance with the existing state of the CPU 42 acquired in step S301. If the drive motor 18 rotates, then control proceeds to step S305.

If the drive motor of the drive 18 does not rotate, control proceeds to step S304, in which a command to rotate the drive motor of the drive 18 is supplied to the CPU 42.

Then, control proceeds to step S305. In response to the command given, the CPU 42 controls the controller of the electric drive 20, providing power to the winding of the drive motor 18.

In step S305, the playback instruction issuing means 108 indicates an arbitrary initial position ((access position data entered in the second register 142) on the recording track of the optical disc 12 and gives a search command to the CPU 42 and providing a search for the access position by the optical head reading 22.

Next, in step S306, the playback controller of the disc 28 sends a rotation command to the CPU 42 and enables the CPU 42 to be set to a standard speed mode.

In step S307, the CPU 42 controls the controller of the electric drive 20, providing power to the winding of the drive motor 18 in accordance with the rotation command given in step S307. In addition, the CPU 42 controls the drive controller of the head 40 in accordance with the search command given in step S307, as a result of which the drive of the head 38 moves the optical pickup 22 along the optical disk 12 in the radius direction until it reaches the initial position indicated by the command to search.

Next, in step S308, the playback controller of the disc 28 sends a playback command to the CPU 42 and reproducing information from the optical disc 12 from the specified initial position.

In step 309, the playback controller of the disc 28 instructs the start of random authentication in the CPU 42.

In step S310, the actual authentication selection process is performed in accordance with a command to start random authentication.

The authentication selection process is carried out practically according to the same scheme, which is shown in Fig.6. In particular, the detection means 104 detects the data of the slow frequency modulation (Dc code) of the radio signal S _RF generated by the optical pickup 22 indicated by the positional data entered in the second register 132, and the authentication selector 106 decides whether the detected code Dc corresponds to the security code Ds .

At the position indicated during the random authentication process, the security code Ds cannot be registered, and a carrier component with a frequency of 22.05 kHz cannot be present. Therefore, the authentication selector 106 selects a nonconfirmation of compliance.

Returning to the program shown in Fig. 7, in step S107, the disc playback controller 28 instructs the end of random authentication to the CPU 42. In accordance with this command, to end the authentication, the CPU 42 controls the security code detector 24 to output the selection result to the controller disc play 28.

As shown in FIG. 8, in step S312, the random authentication selector 112 decides to execute the second rule.

If the selection result obtained from the authentication selector 106 indicates the selection of non-confirmation of compliance, then control proceeds to step S313, in which the confirmation of compliance is declared and after which the random authentication process ends. If the selection result obtained from the authentication selector 106 indicates the selection of the confirmation of compliance, then control proceeds to step S314, in which the non-confirmation of compliance is declared and after which the random authentication process is completed,

In step S7 of the main program shown in FIG. 4, the authentication signal selector 118 decides whether the result of the random authentication process is confirmation or non-confirmation of compliance. If the result of the random authentication process is confirmation of compliance with the norm, then control returns to step S5, in which the authentication signal selector 118 generates a signal Sd indicating the execution / continuation of the program (in this case, a signal to continue the program) received by the execution means programs 116. In response to the signal Sd, the program execution means 116 continues the execution of the currently activated program.

If the result of the absolute authentication process is the non-confirmation of the norm in step S2 or the result of the random authentication process is the non-confirmation of the norm in step S7, then control proceeds to step S8, in which the authentication signal selector 118 generates a signal Se, which is sent to the forced termination means 120 and indicating the forced end of the program.

In response to the signal Se, the forced termination tool 120 generates a command to the display controller 36 and reproduces the image, which is a non-conformity check, on the display screen 50. The display controller 36 controls the display 34, as a result of which the image is displayed on the display screen 50 , which is a non-confirmation of compliance with the norm. For example, display 34d displays the message “THIS DISC CANNOT BE USED”.

In step S9, the forced termination tool 120 issues a forced termination and interruption command to the program execution means 116. In response to this forced termination and interruption command, the program execution means 116 forces the termination of the currently executing program and interrupts data transmission. For example, data transfer to a memory such as a memory card that stores an intermediate game result is interrupted, which makes it impossible to store or read data.

If the processing operations are completed in step S9, the authentication means 100 terminates the processing operations.

The benefits provided by the authentication tool 100 are described below. Prior to this, in terms of the program shown in FIG. 4, it was generally accepted in step S1 to perform only the absolute authentication process.

In particular, in the case of activating a gaming program, data recorded in a specific area of the optical disc 12 is read in order to authenticate. If the authentication result is a confirmation of compliance, then control proceeds to step S5 in order to start the execution of the game program. If the result of authentication is a failure to confirm compliance with the norm, then the game program does not start.

Therefore, if a special device for generating authentication data is always connected to a video game device, as a result of authentication, you can always receive confirmation of compliance with the norm. If a special device for inputting a signal indicating confirmation of compliance with the norm is connected to the playback controller of the disc 28, then as a result of authentication, you can also always receive confirmation of compliance with the norm.

In the case of using such a special device, an authentication result is returned indicating a normal reading of the authentication data, regardless of which region of the optical disk 12 can be read.

According to an embodiment of the present invention, the legitimacy of the optical disk 12 is confirmed in an arbitrary region at an arbitrary time (random authentication process: step S6) in addition to the authentication process described above (absolute authentication process).

In particular, since the authentication data is recorded only in a certain area of the optical disk 12, no authentication data can be read if an arbitrary area of the optical disk 12 is read. If a special device for generating authentication data is constantly connected to the video game device, then returning an authentication result indicating normal reading of authentication data, despite the fact that this device is actually unable to read data authentication from the optical disk 12. In accordance with the principles described above, a decision is made to connect or not connect such a special device for authenticating the optical disk 12. The arbitrary area mentioned above is any area on the optical disk, except for the specified position in which authentication data.

If the result of the random authentication process is confirmation of compliance, that is, the selection result received from the authentication selector 106 indicates the selection of non-confirmation of compliance, then control returns to step S5 and the game program runs continuously.

If the result of the random authentication process is a non-confirmation of compliance with the norm, that is, the selection result received from the authentication selector 106 indicates the selection of the confirmation of compliance with the norm, then the game or data transfer is interrupted to prevent the reading or saving of this data and the forced termination of the current program time. At this time, on the screen 50 of the display 34, for example, the message “THIS DISC CANNOT BE USED” is displayed.

Therefore, even if a special device capable of, as a rule, recognizing as legal an optical disk 12, the legitimacy of which as a rule should not be confirmed, is connected to a video game device 10, reliable detection of this optical disk 12, the validity of which as a rule should not be confirmed, can be ensured. , or this special device in order to interrupt any operations, for example, transferring data to main memory or executing a game program. As a result, it is possible to effectively prevent illegal copying of the optical disk 12.

The authentication means 100 may be provided as a library function, or may be called and executed in an application software program.

Arbitrary position specified during the random authentication process,

matches the address. This address can be freely set as a parameter of the called library function and entered in the second registers 132,142.

Since the address can be freely set at the stage of development of the application software, then for each header, each section and each N parts of the application software, to effectively prevent copying, an address can be set.
