Description

  The present invention relates to an information processing device and method, an information processing system, a recording medium, and a program, and more particularly, to an information processing device and method, an information processing system, a recording medium, and a program that can suppress unauthorized use of authentication information. .

  Authentication techniques using images are becoming popular.

  As a technique of authentication technology, a two-dimensional code has been proposed in which a plurality of rectangular cells are two-dimensionally arranged according to a predetermined arrangement rule. That is, the code number read from the code pattern of the two-dimensional code is a unique (unique) number and can be used as an authentication key for authenticating a specific user.

For example, there may be a usage method in which a concert owner distributes a two-dimensional code as an authentication key to a user who intends to enter a concert venue. In this case, the concert owner assigns a unique code number to the user who purchased the concert admission ticket. Then, the organizer executes a program for generating a two-dimensional code, inputs a code number, generates a predetermined two-dimensional code, and distributes it to the user's mobile phone as an authentication key. The user who received the two-dimensional code and stored it in the mobile phone displays the code on the display screen of the mobile phone at the concert venue. When the organizer recognizes the code number by imaging this two-dimensional code with a dedicated device, and the recognized code number is authenticated as being delivered to the user who purchased the concert admission ticket, Some admissions are permitted (see, for example, Patent Document 1).

  The sound controller 170 generates audio data by digitally converting the audio signal collected by the microphone 113, outputs the audio data to the CPU 150, and converts the audio signal supplied from the CPU 150 into an analog signal. It is generated and output to the outside via the built-in speaker 105.

  Further, an I / O (In / Out) controller 173 is connected to the ISA bus 165, and the power supply switch 106 is turned on when the external power supply is supplied from the external power supply connector 122 via the power supply charge control circuit 185. When this is done, power is supplied to each circuit. Here again, the I / O controller 173 operates based on the system clock supplied from the clock generator 160.

  The power supply charging control circuit 185 is controlled by the I / O controller 173 and controls charging of the battery pack 130 connected to the battery connector 129.

  The I / O controller 173 includes a microcontroller, an I / O interface, a CPU, a ROM, a RAM, and the like, and an OS and application software based on a BIOS (Basic Input / Output System) stored in the flash memory 179. And input / output of data between various peripheral devices such as the liquid crystal display 109 and the HDD 167. Further, the I / O controller 173 is connected to the infrared port 118 and performs infrared communication with other devices, for example.

  Further, the I / O controller 173 is connected to the reversing switch 177. When the image pickup unit 111 is rotated 180 degrees in the direction of the back side of the liquid crystal display 109, the reversing switch 177 is turned on, and this is indicated by the PCI-ISA bridge. The CPU 150 is notified via the 166 and the host-PCI bridge 154.

  In addition, the I / O controller 173 is connected to a full-press / half-press switch 178, and when the shutter button 108 provided on the upper surface of the main body 101 is half-pressed, the full-press / half-press switch 178 is turned on in the half-pressed state and notifies the CPU 150 to that effect, and when the shutter button 108 is in the fully-pressed state, the full-press / half-press switch 178 is turned on in the fully-pressed state, and the CPU 150 is notified of that fact. Notice. That is, the CPU 150 enters the still image mode when the shutter button 108 is pressed halfway by the user while the capture software is launched from the hard disk of the HDD 167 to the RAM 153, and the CCD camera 107 is controlled to freeze the still image. When the button is fully pressed, the frozen still image data is captured and output to the video controller 156.

  In contrast, the CPU 150 enters the moving image mode when the shutter button 108 is fully pressed by the user without starting up the capture software, captures a moving image of up to about 60 seconds, and outputs it to the video controller 156. To do.

  Incidentally, the ROM of the I / O controller 173 stores a wakeup program, a key input monitoring program, an LED control program, a jog dial state monitoring program, and other various control programs.

  The jog dial state monitoring program is a program used in conjunction with the jog dial server program stored in the hard disk of the HDD 167, and is a program for monitoring whether or not the jog dial 124 is rotated or pressed.

  The wake-up program is a program that is controlled by the CPU 150 to execute a predetermined process when the current time supplied from the RTC circuit in the PCI-ISA bridge 166 matches a preset start time. The program is a program for monitoring inputs from the operation keys 103 and other various key switches. The LED control program is a program for controlling lighting of various lamps such as the power lamp PL, the battery lamp BL, and the message lamp ML.

  The RAM of the I / O controller 173 includes an I / O register for a jog dial state monitoring program, a setting time register for a wakeup program, a key input register for a key input monitoring program, an LED control register for an LED control program, and Registers for various other programs are provided.

  The set time register stores time information of a start time arbitrarily set in advance by the user for use in the wakeup program. Therefore, the I / O controller 173 determines whether or not the current time supplied from the RTC circuit matches the arbitrarily set start time based on the wake-up program. Notify CPU 150. As a result, the CPU 150 starts up predetermined application software set in advance at the start time, and executes predetermined processing according to the application software.

  The key input monitoring register stores operation key flags corresponding to input operations such as the operation key 103, the stick 104, the left click button 104A, the right click button 104B, and the center button 105C.

  Therefore, the I / O controller 173 operates, for example, whether or not a pointing operation using the stick 104 or a click operation of the left click button 104A, the right click button 104B, and the center button 104C has been performed based on the key input monitoring program. A determination is made based on the state of the key flag, and when a pointing operation or a clicking operation is performed, the CPU 150 is notified of this.

  Here, the pointing operation is an operation of moving the mouse cursor to a desired position on the screen by pressing the stick 104 up, down, left and right with a finger. The click operation is the left click button 104A or the right click button 104B. This is the operation of quickly pressing and releasing with your finger.

  As a result, the CPU 150 executes a predetermined process corresponding to the movement of the mouse cursor or the click operation by the pointing operation.

  The LED control register stores lighting flags indicating lighting states of various lamps such as the power lamp PL, the battery lamp BL, and the message lamp ML.

  Therefore, the I / O controller 173 stores the lighting flag when the CPU 150 starts up an e-mail program from the hard disk of the HDD 167 by pressing the jog dial 124, and receives an e-mail according to the e-mail program. The message lamp ML is turned on by controlling the LED 181 based on the flag.

  The I / O register for the jog dial state monitoring program stores a rotation operation flag and a press operation flag corresponding to the rotation operation and the press operation with respect to the jog dial 124.

  Accordingly, when the menu item desired by the user is selected from among a plurality of menu items by rotating and pressing the jog dial 124 connected via the rotation detecting unit 188, the I / O controller 173 receives an I / O register. The rotation operation flag and the press operation flag stored in the above are set, and the CPU 150 is notified accordingly.

  As a result, the CPU 150 starts application software corresponding to the menu item determined by the rotation operation and pressing operation of the jog dial 124 according to the jog dial server program read from the HDD 167 and started on the RAM 153, and executes predetermined processing.

  Here, the I / O controller 173 is always operating under the control of the power supply charging control circuit 185 even when the power switch 106 is off and the OS is not activated, thus saving power without providing a dedicated key. The application software or script file desired by the user is activated by pressing the jog dial 124 in a state or when the power is turned off.

  The I / O controller 173 is also connected to the serial bus 182, and supplies various setting parameters for the CCD camera 107 set by the operation key 103 or the jog dial 124 via the serial bus 182, whereby the CCD camera 107 It is designed to adjust the brightness and contrast.

  FIG. 12 is a diagram illustrating an example of an internal electrical configuration of the cybercode generation program issuance / authentication server 11.

  The CPU 201 executes various processes in accordance with programs stored in the ROM 202 or the hard disk device 204. The ROM 202 stores, for example, programs executed at startup and various data. The RAM 203 stores data and programs necessary when various processes are executed by the CPU 201. The hard disk device 204 stores a server program that causes the cybercode generation program issuance / authentication server 11 to function as a server, and various programs described later with reference to FIG.

A program for managing processing for outputting predetermined data to the network interface 207 to be transmitted to another device, or outputting predetermined image data to the display unit 205 to display an image.

The Seed creation program 222 receives a signal corresponding to a command (a request for issuing a cybercode generation program) transmitted from another device by the processing of the input / output management program 221 and, based on the signal, obtains a user ID. Generate (issue) and create a SeedID for random number generation according to the following equation (1).
SeedID = f (UID, TID) (1)

  In the above formula (1), UID represents, for example, a unique user ID assigned to each user of the mobile phone 1, and TID is the time when a cybercode generation program issuance request is received (that is, cybercode generation program issuance). Start time). The created seed ID for random number generation is used when creating a cyber code generation program, as will be described later.

  Here, random numbers will be described. A random number generally indicates a number extracted by random sampling from a set of numbers, and includes a true random number, a physical random number, and a pseudo random number.

  In a true random number, when a bit string is used, the probability of occurrence of 0 and 1 is 1/2, and each bit is iid (independent and identically distributed) independent of other parts.

  The physical random number is obtained by amplifying the effect of quantum mechanics and digitizing it, and if it is smoothed to balance 0 and 1, it becomes a true random number.

  A pseudo-random number is a bit pattern that looks random and is longer than the seed, calculated based on an input bit pattern called a seed. Since the pseudo-random number is generated from a deterministic algorithm, if the seed is determined, the output random number is uniquely determined. Therefore, when used for encryption, it is necessary to keep the seed secret. The seed creation program 222 uses this pseudo-random number. That is, the pseudo-random number is used for the created cyber code generation program, and the seed that is used as a base is generated by the Seed creation program 222.

  Returning to the description of FIG. The cyber code generation program issuing unit 223 receives the supply of a signal corresponding to a command (request for issuing a cyber code generation program) transmitted from another device by the processing of the input / output management program 221 and performs processing of the seed generation program 222 For example, P (UID, TID, SeedID based on the SeedID for random number generation generated by the user, the user ID (UID) representing the user of the mobile phone 1 that issued the request, and the cybercode generation program issuance start time TID ) Create a unique cybercode generation program PID (Java (registered trademark) applet) for each user as represented by (t).

  The cyber code generation program issuance / authentication server 11 can use the algorithm itself as an authentication key by distributing a program having an algorithm specific to each user to the user.

  The cyber code generation program issuing unit 223 sends the created cyber code generation program PID unique to each user via the Internet 7, the Internet service provider 6, the public network 5, and the base station 2. Transmit to the telephone 1.

  The authentication key separation program 224 receives a signal corresponding to a command (a code number of a cyber code generated by executing a cyber code generation program) transmitted from another device by the processing of the input / output management program 221. Separate the user ID included in the code number. For example, among the code numbers represented by 8 digits, when the lower 4 digits are embedded as the user ID, the code numbers are separated into the upper 4 digits and the lower 4 digits.

  The authentication program 225 is authenticated by receiving a signal corresponding to a command (a code number of a cyber code generated by executing the cyber code generation program) transmitted from the ticketless terminal 3 by the processing of the input / output management program 221. Based on the user ID separated by the processing of the key separation program 224, the corresponding user ID issuance start time TID and random number generation SeedID are searched from the registered user information database 12.

  The authentication program 225 creates a cyber code generation program PID from the user ID, the searched start time TID and the seed for random number generation, and executes the program based on the code number reception time. The authentication program 225 compares the code number generated by the execution of the cyber code generation program PID and the received code number, and if they match, the authentication program 225 indicates that the authentication was successful, the input / output management program 221, the network interface 207, and It transmits to the ticketless terminal 3 via the Internet 7.

  The download screen shown in FIG. 17 displays items such as “cyber ticket for authentication” and “money for authentication” that can be selected by the user. When the user uses the operation key 41 or the jog dial 44 to select the item “Cyber Ticket for Authentication”, the input / output control program 81 supplies a signal indicating the operation input by the user to the web browser 82.

  The web browser 82 issues / authenticates the cyber code generation program of the cyber code authentication site 8 to the data communication program 87 via the antenna 31, the base station 2, the public line network 5, the Internet service provider 6, and the Internet 7. The server 11 is caused to transmit a signal indicating the operation input by the user, receive the corresponding HTML file from the cybercode generation program issuance / authentication server 11, and supply it to the display program 83.

  The display program 83 causes the liquid crystal display 35 to display a cyber ticket download screen as shown in FIG. 18, for example, based on the supplied HTML file.

  In the cyber ticket download screen shown in FIG. 18, “△ × game”, “× ○ movie admission”, “○ △ concert”, “× □ game”, and “□ ○” are selectable (downloadable) by the user. The “Concert” item is displayed. When the user uses the operation key 41 or the jog dial 44 to select the “◯ △ concert” item, the input / output control program 81 supplies a signal indicating the operation input by the user to the web browser 82.

  The web browser 82 causes the display program 83 to display a user registration screen as shown in FIG.

  In the user registration screen shown in FIG. 19, “Yes” and “No” items for prompting the selection are displayed together with a message such as “Do you want to register a user ID for downloading a concert authentication cyber ticket?”. Display. When the user selects the “Yes” item using the operation key 41 or the jog dial 44, the input / output control program 81 supplies a signal indicating the operation input by the user to the web browser 82.

  The web browser 82 issues / authenticates the cyber code generation program of the cyber code authentication site 8 to the data communication program 87 via the antenna 31, the base station 2, the public line network 5, the Internet service provider 6, and the Internet 7. The server 11 is caused to transmit a signal indicating an operation input by the user. Thereby, the cyber code generation program issuance / authentication server 11 is requested to issue the cyber code generation program.

  In step S12, the input / output management program 221 of the cyber code generation program issuance / authentication server 11 receives a cyber code generation program issuance request from the mobile phone 1 via the network interface 207, and seeds a signal indicating the request. This is supplied to the creation program 222 to generate a seed ID for random number generation.

  The Seed creation program 222 acquires the current time TID at which the cybercode generation program issuance request is received, generates a unique user ID for each user based on the time TID, and also generates the generated user ID and time TID. Based on the above, a SeedID for random number generation is created according to the above equation (1).

  In step S13, the cyber code generation program issuing unit 223 generates a cyber code generation program PID based on the random number generation SeedID, user ID, and time TID generated in the process of step S12. In the cyber code generation program PID created here, the user ID is embedded in the last four digits of the code number (ID part 233) of the cyber code generated by executing the program. That is, since a user ID is required at the time of authentication, the user ID is embedded in the code number.

  In step S14, the cyber code generation program issuing unit 223 determines whether or not the creation of the cyber code generation program PID is successful. If it is determined that the creation of the cyber code generation program PID is successful, the process proceeds to step S15. In association with the generated user ID, the cybercode generation program issue start time TID and the seeded ID for random number generation are recorded in the registered user information database 12.

  In step S16, the cyber code generation program issuing unit 223 uses the cyber code generation program PID created in step S13 as the input / output management program 221, the network interface 207, the Internet 7, the Internet service provider 6, and the public network 5 And to the mobile phone 1 via the base station 2.

  On the other hand, if it is determined in step S14 that the creation of the cyber code generation program PID was not successful due to a system error or the like, that is, the creation of the cyber code generation program PID failed, the process proceeds to step S17. The code generation program issuing unit 223 notifies that the creation of the cyber code generation program has failed via the input / output management program 221, the network interface 207, the Internet 7, the Internet service provider 6, the public line network 5, and the base station 2. To the mobile phone 1.

  In step S <b> 3, the data communication program 87 of the mobile phone 1 determines whether or not a cyber code generation program creation failure notification is received from the cyber code generation program issuance / authentication server 11 via the antenna 31. If it is determined that the notification of the creation failure of the code generation program has been received, the process proceeds to step S4, and a signal indicating the received notification of the creation failure of the cyber code generation program is supplied to the display program 83. Based on the supplied signal, the display program 83 causes the liquid crystal display 35 to display an error message such as “Cyber code generation program download failed”, for example.

  If it is determined in step S3 that a notification of failure to create the cyber code generation program has been received, the process proceeds to step S5, where the data communication program 87 of the mobile phone 1 issues the cyber code generation program via the antenna 31. / The cyber code generation program PID transmitted from the authentication server 11 is received and recorded in the memory 86 as a Java (registered trademark) applet 91.

  After step S4 or step S5, in step S6, the web browser 82 causes the data communication program 87 to cancel communication with the cybercode generation program issuance / authentication server 11, and the process ends.

  Through the above processing, the mobile phone 1 can acquire a unique cyber code generation program PID for each user, and an authentication key is used for the cyber code generated by executing the cyber code generation program, which will be described later with reference to FIG. Can be used as

  Next, referring to the flowchart of FIG. 20, the user of the mobile phone 1 executes the cybercode generation program PID acquired (downloaded) by the above-described process, and enters the admission ticket for the concert held at the concert venue 4. A process of generating an alternative cyber code, causing the ticketless terminal 3 to recognize the cyber code, and authenticating the recognized code number at the cyber code authentication site 8 will be described.

  The user of the cellular phone 1 uses the operation key 41 or the jog dial 44 to display a menu screen as shown in FIG. 16 on the liquid crystal display 35 and selects the item “Java (registered trademark) applet”. Thus, in step S31, the Java (registered trademark) applet execution program 85 supplies a signal indicating the operation input by the user to the display program 83, and displays a Java (registered trademark) applet execution screen as shown in FIG. It is displayed on the liquid crystal display 35.

  In the Java (registered trademark) applet execution screen shown in FIG. 21, Java (registered trademark) applets (cyber code generation program PID) downloaded by the user, such as “XX Concert” and “XX Movie Entrance”, are displayed. Items are displayed. When the user uses the operation key 41 or the jog dial 44 to select the item “◯ △ concert”, the Java (registered trademark) applet execution program 85 selects the cybercode generation program corresponding to the selected “◯ △ concert”. Execute PID.

  In step S32, the Java (registered trademark) applet execution program 85 executes a cyber code recognition process with the ticketless terminal 3 based on the current time Tu.

  Here, with reference to the flowchart of FIG. 22, the cyber code recognition process between the mobile phone 1 and the ticketless terminal 3 will be described.

  In step S71, the Java (registered trademark) applet execution program 85 resets a counter n (not shown) to zero.

  In step S72, the code ID generation unit 85a (of the cyber code generation program PID) generates the seed ID for random number generation generated by the processing of the seed generation program 222, the user ID (UID) indicating the user of the mobile phone 1 that has issued the issue request. ) And a plurality of unique code IDs corresponding to the code numbers for each user as represented by P (UID, TID, SeedID) (t), for example, based on the cybercode generation program issue start time TID To do.

  Here, a plurality of unique code IDs to be generated are represented by coefficients of calculation represented by the following equation (2).

P (UID, TID, SeedID) (t) = C ₁ +2 ³³ × C ₂ +2 ^{33 × 2} × C ₃ +2 ^{33 × 3} × C ₄ + ... + 2 ^{33 × (m-1)} × C _m
... (2)

Here, the coefficient m is a value indicating the number of generated coefficients. That is, the code ID generation unit 85a calculates the coefficients C _{1 to} C _m in the equation (2) as a plurality of code IDs.

In step S73, the two-dimensional code generation unit 85b generates a cyber code including a two-dimensional code based on the plurality of code IDs generated by the code ID generation unit 85a. That is, the two-dimensional code generation unit 85b generates a cyber code based on C _{1 to} C _m that are code IDs generated by the process of step S72.

  In step S 74, the Java (registered trademark) applet execution program 85 generates a start code based on the number m of cyber codes to be transmitted, controls the display program 83, and displays it on the liquid crystal display 35. That is, the Java (registered trademark) applet execution program 85 controls the two-dimensional code generation unit 85 b to generate a start code cybercode including information on the number m of the cybercodes to be transmitted, and displays it on the liquid crystal display 35. Let

  Thus, for example, as shown in FIG. 23, the generated cyber code (authentication cyber ticket) 241 is displayed together with information indicating the contents of the cyber code such as “◯ △ concert authentication cyber ticket” and the current time. The

  In step S91, the cyber code finder 192 determines whether or not a cyber code as a start code has been detected based on an image captured by the CCD camera 107, and the process is performed until a cyber code as a start code is detected. repeat. For example, if it is determined in step S74 that a start code cybercode has been detected, the process proceeds to step S92.

  In step S92, the authentication program 193 recognizes the number m of cyber codes scheduled to be transmitted included in the start code cyber code.

  In step S75, the Java (registered trademark) applet execution program 85 increments the counter n by 1. In step S76, it is determined whether or not a predetermined time has elapsed, and the process is performed until the predetermined time has elapsed. If it is determined repeatedly that the predetermined time has elapsed, the process proceeds to step S77.

  In step S77, the Java (registered trademark) applet execution program 85 determines that the counter n is larger than m, that is, the number of code IDs displayed so far (= the number of cyber codes displayed so far) n is It is determined whether or not the number of all cyber codes to be generated is larger than m, and if it is determined that the counter n is not larger than m, the display program 83 is controlled in step S78, and the nth cyber code is determined. Displayed on the display 35, the process returns to step S75, and the subsequent processes are repeated.

  If it is determined in step S77 that the counter n is greater than m, the process ends.

  That is, the cyber codes generated corresponding to the respective code IDs are sequentially displayed on the display 35 at predetermined time intervals, and after all the cyber codes are displayed, the process ends.

  In step S93, the cyber code finder 192 determines whether or not a cyber code is detected, and repeats the processing until it is detected. In step S93, for example, when it is determined that the cyber code is displayed by the process of step S78, it is determined that the cyber code is detected. In step S94, the cyber code finder 192 recognizes the displayed cyber code. The code ID indicated by the cyber code is acquired.

  In step S95, the cyber code finder 192 determines whether the cyber code is the m-th cyber code, that is, whether it is the last cyber code among the cyber codes scheduled to be transmitted, and is not the m-th cyber code. If it is determined, the process returns to step S93, and the subsequent processes are repeated. If it is determined in step S95 that it is the m-th cyber code, in step S96, the authentication program 193 calculates the above equation (2) from a plurality of code IDs, and calculates P (UID , TID, SeedID) (t) is calculated as a code number.

  When the cyber code generation program PID is executed by the above processing, the cyber code 241 is generated based on the current time. The cyber code 241 is (at a predetermined time interval as shown in FIG. For example, it is updated (changed) every 1 second).

In the case of the example of FIG. 24, the cyber code 241-1 is generated based on the time t1, the cyber code 241-2 is generated based on the time t2, the cyber code 241-3 is generated based on the time t3, and the time cyber code 241-4 is generated based on t4, similarly, the cyber code 241 at a predetermined time interval _{(= t 2 -t 1 = t} 3 -t 2 = t 4 -t 3) are generated.

  That is, after the cyber code is generated by the mobile phone 1, the code number obtained by recognizing the code pattern by the ticketless terminal 3 is transmitted to the cyber code authentication site 8. The user ID included in the ID is separated, and the seed ID for random number generation is created based on the separated user ID, and the cyber code generation program PID is again generated from the generated seed ID for random number generation, the user ID, and the code number reception time. The code number generated and generated by executing the program is guaranteed to be generated at the same time as the code number generated by the mobile phone 1.

In the example of FIG. 23, a case is shown in which a code number is expressed by a set of a total of four cyber codes of cyber codes 241-1 to 241-4. In FIG. 23, each of the cyber codes 241-1 to 241-4 indicates the coefficients C _{1 to} C ₄ that are code IDs, and the above equation (2) is calculated based on these code IDs. Code number is obtained. In FIG. 23, the case where the number of cyber codes is four is described, but it goes without saying that other numbers may be used.

Furthermore, these cyber code sets are set at intervals Z longer than the above-described time intervals (for example, the above-described predetermined time intervals (= t ₂ −t ₁ = t ₃ ), depending on the time of operation by the mobile phone 1. If -t ₂ = t ₄ -t ₃ ) is about 1 second and the total number of cybercodes is about 4, it will change at a time interval of about 20 to 30 seconds). That is, for example, a set of cyber codes 241-1 to 241-4 is generated based on a certain time Tu, and a set of cyber codes 241-1 to 241-4 is recognized at the time (Tu + X). The code number obtained from the recognized cyber code set is transmitted to the cyber code authentication site 8, and the cyber code set generated based on the time (Tu + Y) in the cyber code authentication site 8 is, for example, time If the intervals X and Y (Y> X) are shorter than the above-described time interval Z, they can be the same.

  Thus, the time Tu when the cyber code generation program PID is executed on the mobile phone 1 and the time Tu when the cyber code generation program PID is created again at the cyber code authentication site 8 and the program is executed are the same time. There can be. That is, the same cyber code generation program PID is executed within a predetermined time, and it is authenticated that the same set of cyber codes is generated.

  That is, by shortening the time interval at which the cyber code 241 is generated, the expiration date of the code number represented by the set of a plurality of generated cyber codes is shortened, and unauthorized authentication due to cyber code theft is suppressed. Authentication accuracy can be improved.

  In addition, since one code number is expressed by the correlation of multiple cyber codes, the code number is reproduced even if one cyber code is imaged by the still camera etc. on the liquid crystal display 35 being authenticated. This is impossible and cannot be used illegally, so that the authentication accuracy can be further improved.

  Returning to the description of FIG. In step S32, the user of the mobile phone 1 holds the cyber code 241 displayed on the liquid crystal display 35 over the CCD camera 107 of the ticketless terminal 3, and adjusts the position so that the cyber code 241 is imaged. .

  At this time, in the ticketless terminal 3, the cyber code finder 192 is activated in advance, and a screen as shown in FIG. 25 is displayed on the liquid crystal display 109, for example.

  In step S <b> 41, the cyber code finder 192 of the ticketless terminal 3 executes a process of capturing an image by the CCD 107 and executes a process of recognizing the cyber code from the captured image. At this time, for example, as shown in FIG. 26, the screen displayed on the liquid crystal display 109 displays a message such as “authenticating” to inform the user that the cyber code is being authenticated. .

  The cyber code finder 192 recognizes the code number obtained from the code pattern of the cyber code from the captured image. In step S42, the authentication program 193 transmits the recognized code number to the cyber code authentication site 8 and requests execution of user authentication.

  In step S51, the cybercode generation program issuance / authentication server 11 of the cybercode authentication site 8 receives the code number transmitted from the ticketless terminal 3, and receives a user authentication request. In step S52, the cyber key generation program issuance / authentication server 11 authentication key separation program 224 separates the user ID from the code number received in step S51.

  In step S53, the authentication program 225 searches the registered user information database 12 for the corresponding user ID issuance start time TID and random number generation SeedID, based on the user ID separated in step S52. In step S54, the authentication program 225 creates the cyber code generation program PID again from the user ID separated in the process of step S52, the time TID searched in the process of step S53, and the seeded ID for random number generation.

  In step S55, the authentication program 225 executes the cyber code generation program PID created in step S54 based on the code number reception time, and generates authentication information including the code number. In step S56, the authentication program 225 performs one-way matching (authentication process) from the code number generated by the process of step S55 and the code number received by the process of step S51.

  For the authentication process, the code number has not expired (for example, a certified cyber ticket for a previously held concert has been copied and the concert date has not passed), or authentication It is determined whether the generated code number is created from a predetermined user ID, time TID, and SeedID for random number generation (for example, created by another cybercode generation program PID) .

  In step S <b> 57, the authentication program 225 transmits the authentication result to the ticketless terminal 3 via the input / output management program 221, the network interface 207, and the Internet 7.

  In step S43, the authentication program 193 of the ticketless terminal 3 displays the authentication result supplied from the cybercode authentication site 8 on the liquid crystal display 109. Thereby, for example, as shown in FIG. 27, a message such as “authentication was successful!” Is displayed.

  As described above, the cyber code authentication site 8 generates the cyber code from the user ID of the user of the mobile phone 1 that has made the cyber code issue request, the time TID at which the cyber code generation program issue request is received, and the Seed ID for random number generation. A program PID is created, the created program is distributed to the requesting user, and the information is recorded in the registered user information database 12. Then, the cyber code authentication site 8 obtains the corresponding time TID and random number generation SeedID from the registration information database 12 based on the user ID included in the code number transmitted from the ticketless terminal 3 at the time of authentication. The cyber code generation program PID is created again (that is, the same cyber code generation program PID as the user who is trying to authenticate is created), the code number is generated, and it is authenticated. It can have an authentication key function.

  Further, in the mobile phone 1 and the ticketless terminal 3, the code IDs of a plurality of cybercodes that are displayed continuously and the code number are used for the authentication based on the correlation thereof, so that the liquid crystal display can be used during the authentication process. Even if the image displayed on the screen 35 is picked up by a still camera or the like, the code number cannot be reproduced with the single image, so that unauthorized authentication can be suppressed.

  Moreover, since the cyber code is generated based on the time, it can be used as an authentication key with an expiration date indicating that it is the only cyber code at the time of authentication.

  In the above example, the mobile phone 1 and the ticketless terminal 3 can express the code number with a plurality of code IDs, and further generate a plurality of cyber codes corresponding to the code IDs at predetermined time intervals. Although an example in which a code number is presented by displaying has been described, information on the order of coefficients may be included in each of the plurality of cyber codes, and the order may be changed at random.

  FIG. 28 shows a function of the mobile phone 1 that randomly changes the display order of a plurality of cyber codes. Of the functions of the mobile phone 1 of FIG. 28, the same functions as those of the mobile phone 1 of FIG. 6 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  The function of the cellular phone 1 in FIG. 28 is different from the function of the cellular phone 1 in FIG. 6 in that a Java (registered trademark) applet execution program 301 is provided instead of the Java (registered trademark) applet execution program 85. is there. The Java (registered trademark) applet execution program 301 includes a code ID generation program 301a and a two-dimensional code generation unit 301b. Basically, only the two-dimensional code generation unit 301b is different, and other functions are provided. Is the same as the Java (registered trademark) applet execution program 85.

  When the two-dimensional code generation unit 301b generates a cyber code corresponding to a plurality of code IDs, the two-dimensional code generation unit 301b includes information indicating the order of each cyber code (information identifying which coefficient is described above). Generated, and then output by changing the order.

  FIG. 29 shows a function of the ticketless terminal 3 that recognizes a plurality of cyber codes displayed in a random order and acquires a code number. Of the functions of the ticketless terminal 3 of FIG. 29, the same functions as those of the ticketless terminal 3 of FIG. 11 are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

  The function of the ticketless terminal 3 in FIG. 29 is different from the function of the ticketless terminal 3 in FIG. 11 in that a cyber code finder 321 and an authentication program 322 are provided instead of the cyber code finder 192 and the authentication program 193. is there.

  The cyber code finder 321 basically has the same function as the cyber code finder 192. However, the cyber code finder 321 recognizes the code ID of each cyber code and further determines the order of each cyber code (which item in the above-described equation (2)). Recognizing that the coefficient is

  The authentication program 322 basically has the same function as the authentication program 193, but further calculates the code number by rearranging in the order of the code ID based on the order of each cyber code.

  Next, cybercode recognition processing executed by the functions of the mobile phone 1 shown in FIG. 28 and the ticketless terminal 3 shown in FIG. 29 will be described with reference to the flowchart of FIG. Note that the processing of steps S111, S112, S114, and steps S116 to S118, and the processing of steps S131 to S133, S135, and S137 in the flowchart of FIG. 30 are the same as steps S71, S72, S74 to S77 of FIG. Also, since it is the same as the processing of steps S91 to S93, S95, and S96, description thereof will be omitted.

In step S113, the two-dimensional code generation unit 301b includes a cyber code including the two-dimensional code based on the plurality of code IDs generated by the code ID generation unit 301a and includes information indicating the order of each cyber code. To generate. That is, the two-dimensional code generation unit 301b generates a cyber code based on each code ID including information for identifying C _{1 to} C _m that are code IDs generated by the process of step S112.

  In step S115, the two-dimensional code generation unit 301b changes the order of the generated cyber codes. That is, the cyber code is generated in the order corresponding to the order of the coefficient serving as the code ID, but the two-dimensional code generation unit 301b changes this order at random.

  In step S119, the Java (registered trademark) applet execution program 301 controls the display program 83 to display the rearranged n-th cybercode on the display 35, and the process returns to step S116 and thereafter. The process is repeated.

  In step S134, the cyber code finder 192 recognizes the displayed cyber code, acquires the code ID indicated by the cyber code, and acquires information indicating the order of the code ID.

  In step S136, the authentication program 193 rearranges the code IDs based on the information indicating the order of the code IDs, and generates a code ID indicating the original coefficient.

  By the above processing, for example, in step S113, four cyber codes 241-11 to 241-14 as shown in FIG. 31 are generated. That is, as shown in FIG. 31, the two-dimensional code generation unit 301 b assigns to each of the cyber codes 241-11 to 241-14 an index 331-1 to 331-consisting of 4 bits indicated by a bold line in the drawing. 4 is generated, and the indexes 331-1 to 331-4 are generated including information indicating the respective orders.

  When the ticketless terminal 3 obtains the plurality of cyber codes in a randomly rearranged state, the authentication program 193 assigns each cyber code to each cyber code based on information indicating the order of the indexes 331-1 to 331-4. The order of the corresponding code IDs is rearranged to generate a code ID indicating the original coefficient, and the code number is calculated.

  As a result, in the mobile phone 1 and the ticketless terminal 3, the code number is used for authentication by changing the display order of a plurality of cybercodes that are displayed continuously at random and displaying them. Even if an image displayed on the liquid crystal display 35 is captured during processing, the code number cannot be reproduced, so that unauthorized authentication can be suppressed and a continuously displayed cyber code Since it is possible to confirm the order of the code IDs expressed by, it is also possible to confirm the presence or absence of an error such that one piece of cyber code is lost during authentication.

  In the above example, in the mobile phone 1 and the ticketless terminal 3, the code number can be expressed by a plurality of code IDs, and a plurality of cyber codes corresponding to the code IDs are generated, and a predetermined time interval is generated. In the above example, the code number is presented by changing the display order at random, but the code number based on the difference between the code IDs of each of these cyber codes is presented. You may make it do.

  FIG. 32 shows the function of the mobile phone 1 in which the code number is presented based on the difference between the code IDs indicated by the plurality of cyber codes. Of the functions of the mobile phone 1 in FIG. 32, the same functions as those of the mobile phone 1 in FIG. 6 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  32 differs from the function of the mobile phone 1 in FIG. 6 in that a Java (registered trademark) applet execution program 351 is provided in place of the Java (registered trademark) applet execution program 85. is there. The code ID generation program 351a generates a plurality of code IDs that can express a code number using the difference. The two-dimensional code generation unit 351b is basically the same as the two-dimensional code generation unit 85b. However, in the start code, the two-dimensional code generation unit 351b generates a cyber code that includes information indicating only the start of transmission. A stop code is generated as a cyber code indicating only information, and transmitted at the beginning and end respectively.

  FIG. 33 shows the function of the ticketless terminal 3 that acquires a code number based on the difference between the code IDs indicated by a plurality of cyber codes. Of the functions of the ticketless terminal 3 of FIG. 33, the same functions as those of the ticketless terminal 3 of FIG. 11 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  The function of the ticketless terminal 3 in FIG. 33 differs from the function of the ticketless terminal 3 in FIG. 11 in that a cyber code finder 371 and an authentication program 372 are provided instead of the cyber code finder 192 and the authentication program 193. is there.

  The cyber code finder 371 basically has the same function as the cyber code finder 192, but further recognizes the start and end of cyber code transmission by the start code and stop code of each cyber code.

  The authentication program 372 basically has the same function as the authentication program 193, but calculates a code number based on a difference between code IDs corresponding to each cyber code.

  Next, with reference to the flowchart of FIG. 34, the cyber code recognition process executed by the respective functions of the mobile phone 1 shown in FIG. 32 and the ticketless terminal 3 shown in FIG. Note that the processes of steps S151, S153, S155, S156, and S158, and the processes of steps S172 and S173 in the flowchart of FIG. 34 are the same as the processes of steps S71, S73, S75, S76, and S78 of FIG. Since this is the same as the processing in steps S93 and S94, the description thereof will be omitted.

  In step S152, the code ID generation unit 351a generates a code ID so that the code number can be expressed based on the difference between the plurality of code IDs.

  In step S154, the Java (registered trademark) applet execution program 351 generates a start code indicating the start of transmission of the cyber code, controls the display program 83, and displays it on the liquid crystal display 35.

  In step S157, the Java (registered trademark) applet execution program 351 determines whether or not the untransmitted cybercode is only the last cybercode, and if it is determined that it is not the last cybercode, the processing is as follows. Proceed to step S158. On the other hand, when it is determined in step S157 that it is the last cyber code, in step S159, the Java (registered trademark) applet execution program 351 generates a stop code indicating the end of transmission of the cyber code, and displays the display program 83. It controls and displays on the liquid crystal display 35, and the process is complete | finished.

  In step S171, the cyber code finder 371 determines whether or not a cyber code as a start code has been detected based on an image captured by the CCD camera 107, and the process is performed until a cyber code as a start code is detected. repeat. For example, if it is determined in step S154 that a start code cybercode has been detected, the process proceeds to step S172.

  In step S174, the cyber code finder 371 determines whether or not the detected cyber code is a stop code. If it is determined that the detected cyber code is not a stop code, the process returns to step S172, and the subsequent processes are repeated. It is. In step S174, for example, when the stop code is displayed by the process of step S159 and it is determined that the code is a stop code, in step S175, the authentication program 372 determines the code number based on the difference between the plurality of code IDs. calculate.

  For example, when it is desired to present 692 as the code number by the above processing, in step S152, the code ID generation unit 351a generates, for example, 1033, 1039, 1048, and 1050 as the code ID. In step S153, as shown in FIG. 35, the two-dimensional code generation unit 351b generates cyber codes 241-21 to 241-24 so as to correspond to the respective code IDs. Furthermore, it is assumed that cybercodes 241-21 to 241-24 are displayed at times t31 to t34 by the process of step S158.

  In this case, the code IDs are acquired in the order of 1033, 1039, 1048, and 1050 by the processing in step S173. At this time, the authentication program 372 calculates the code number 692 by sequentially obtaining the difference between the respective code IDs. That is, as indicated by the numbers in the circles in FIG. 35, 6 (= | 1033-1039 |), 9 (= | 1048-1039 |), 2 (= | 1048-1050 |) are calculated as code numbers. Is done.

  Through the above processing, one code number is expressed by the difference of each code ID that is a correlation between a plurality of cyber codes, so even if the liquid crystal display 35 being authenticated is imaged by a still camera or the like. Since it cannot be used for authentication and as a result cannot be used illegally, the authentication accuracy can be improved.

  In the above description, the code number is generated based on the code ID difference. However, the code number may be generated based on the time difference when the cyber code is displayed.

  FIG. 36 shows the function of the mobile phone 1 that presents code numbers based on the time difference indicated by a plurality of cyber codes. Of the functions of the mobile phone 1 in FIG. 36, the same functions as those of the mobile phone 1 in FIG. 32 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  36 differs from the function of the mobile phone 1 of FIG. 32 in that a Java (registered trademark) applet execution program 391 is provided instead of the Java (registered trademark) applet execution program 351. is there. The Java (registered trademark) applet execution program 391 monitors the playback time of each cyber code, and controls the display program 83 to display the cyber code when the playback time comes.

  The code ID generation program 391a generates a plurality of code IDs that can express a code number using a difference in time at which a cyber code is displayed, and also generates time information for displaying each of the code IDs. The two-dimensional code generation unit 391b is the same as the two-dimensional code generation unit 351b.

  FIG. 37 shows the function of the ticketless terminal 3 that acquires a code number based on the difference in time at which a plurality of cyber codes are displayed. Of the functions of the ticketless terminal 3 of FIG. 37, the same functions as those of the ticketless terminal 3 of FIG. 33 are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

  The function of the ticketless terminal 3 in FIG. 37 is different from the function of the ticketless terminal 3 in FIG. 33 in that a cyber code finder 411 and an authentication program 412 are provided instead of the cyber code finder 371 and the authentication program 372. is there.

  The cyber code finder 411 basically has the same function as the cyber code finder 371, but further recognizes the time when each cyber code was acquired.

  The authentication program 412 basically has the same function as the authentication program 372, but the code number calculation method is different, and the code number is calculated based on the difference between the times when each cyber code is acquired.

  Next, with reference to the flowchart of FIG. 38, the cyber code recognition process executed by the respective functions of the mobile phone 1 shown in FIG. 36 and the ticketless terminal 3 shown in FIG. Note that the processes of steps S191, S193 to S195, and S197 to S199, and the processes of steps S211, S212, and S214 in the flowchart of FIG. 38 are the same as steps S151, S153 to S155, and S157 to S157 of FIG. Since it is the same as the process of S159 and the processes of steps S171, S172, and S174, the description thereof is omitted.

  In step S192, the code ID generation unit 391a generates a code ID so that the code number can be expressed based on the difference between the display times of the cyber codes corresponding to the plurality of code IDs, and the display time of each code ID. Calculate In this case, the code ID itself may not include information regarding the code number. Therefore, the generated code ID itself may be unrelated to the code number.

  In step S196, the Java (registered trademark) applet execution program 391 determines whether or not it is time to display the nth cybercode, and repeats the process until it is time to display the nth cybercode. If it is determined that it is time to display the n-th cyber code, the processing proceeds to step S197.

  That is, by this process, in the process of step S198, the cyber code corresponding to the code ID calculated in the process of step S192 is displayed at the time set for each code ID.

  In step S213, the cyber code finder 411 recognizes the displayed cyber code, acquires the code ID indicated by the cyber code, and stores the time when the cyber code was acquired.

  In step S215, the authentication program 412 calculates a code number based on the difference between times when a plurality of code IDs are captured.

  For example, as shown in FIG. 39, the cyber code 241-31 is displayed on the liquid crystal display 35 at the time t41 = 0'00 '' by the processing of step S198, and the cyber code 241-32 is displayed at the time t42 = 0. “05” is displayed, the cyber code 241-33 is displayed at time t43 = 0′10 ″, and the cyber code 241-34 is displayed at time t44 = 0′13 ″. To do.

  In this case, the ticketless terminal 3 acquires the cyber code 241-32 5 seconds after the cyber code 241-31 and the cyber code 241-33 is acquired 5 seconds after the cyber code 241-32 in the process of step S 212. Furthermore, the cyber code 241-34 is acquired 3 seconds after the cyber code 241-33.

  As a result, the authentication program 412 calculates (553), which is the difference between the times when these cyber codes 421-31 to 421-34 are acquired, as a code number.

  Through the above processing, one code number is expressed by the difference in time when multiple cyber codes are displayed. Therefore, even if the liquid crystal display 35 under authentication is imaged with a still camera etc., it is used illegally. Since it cannot be performed, the authentication accuracy can be improved.

  In the above, an example in which one cyber code is presented on the liquid crystal display 35 has been described. However, a plurality of cyber codes may be displayed at the same time so that the plurality of cyber codes are recognized simultaneously. Good.

  FIG. 40 shows the function of the mobile phone 1 in which a plurality of cyber codes are displayed simultaneously and a code number is presented. Of the functions of the mobile phone 1 in FIG. 40, the same functions as those of the mobile phone 1 in FIG.

  40 differs from the function of the mobile phone 1 in FIG. 6 in that a display program 431 is provided instead of the display program 83. The display program 431 arranges and displays a plurality of cyber codes at predetermined positions.

  FIG. 41 shows the function of the ticketless terminal 3 that obtains a code number based on a plurality of cyber codes displayed at the same time. Of the functions of the ticketless terminal 3 of FIG. 41, the same functions as those of the ticketless terminal 3 of FIG. 11 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  The function of the ticketless terminal 3 in FIG. 41 is different from the function of the ticketless terminal 3 in FIG. 11 in that a cyber code finder 451 is provided instead of the cyber code finder 192.

  The cyber code finder 451 basically has the same function as the cyber code finder 192, but recognizes the positions of a plurality of cyber codes and simultaneously recognizes the plurality of cyber codes in the order corresponding to the positions.

  Next, with reference to the flowchart of FIG. 42, the cybercode recognition process executed by the respective functions of the mobile phone 1 shown in FIG. 40 and the ticketless terminal 3 shown in FIG. Note that the processing of steps S231, S232, and S251 in the flowchart of FIG. 42 is the same as the processing of steps S72, S73, and S93 of the flowchart of FIG.

  In step S233, the Java (registered trademark) applet execution program 85 controls the display program 431 to display a plurality of cyber codes arranged in a predetermined order. That is, for example, when the cyber codes 241-41 to 241-44 are generated, they are arranged and displayed in the order indicated by the arrows shown in FIG. 43.

  In step S252, the cyber code finder 451 recognizes the displayed plurality of cyber codes and acquires a code ID indicated by the cyber code. That is, when a cyber code as shown in FIG. 43 is represented, the cyber code finder 451 recognizes 2 × 2 total of four cyber codes and acquires each code ID.

  In step S253, the cyber code finder 451 confirms the position of each displayed cyber code, and recognizes the order corresponding to the position of each cyber code. That is, in the case of FIG. 43, the cyber code finder 451 recognizes that the cyber codes 421-41 to 241-44 have been acquired in the order of the upper right, the upper left, the lower right, and the lower left.

  In step S254, the authentication program 193 calculates the above formula (2) from a plurality of code IDs, and calculates P (UID, TID, SeedID) (t) obtained by the calculation as a code number.

  By displaying a plurality of cyber codes 241 by the above processing, the display size of each cyber code is reduced, so that even if the cyber code is imaged from a distant position, the resolution is lowered. In addition, unauthorized authentication due to cyber code theft can be suppressed and authentication accuracy can be improved.

  Further, in the ticketless system described above, it is possible to solve problems based on i-appli restrictions. That is, i-applis are generally known to have the following restrictions. (1) In order to protect security, an i-appli can access only the site from which the program is downloaded using internal processing. (2) For security protection, it is not permitted to establish a communication by calling an arbitrary place (site) by processing inside the program.

  Therefore, when a mobile phone communicates with a predetermined authentication server for authentication using a Java (registered trademark) applet, the Java (registered trademark) applet issuing server and the authentication server must be the same.

  In addition, in order to have a single authentication program for each user, it is necessary to configure an authentication server that performs all events at once.

  On the other hand, according to the ticketless system of the present invention, the mobile phone 1 on which the cyber code generation program (Java (registered trademark) applet) has been downloaded does not communicate with the cyber code generation program issue / authentication server 11. Since the ticketless terminal 3 communicates with the cyber code generation program issuance / authentication server 11, the access destination is not restricted.

  Further, it is possible to provide a cybercode generation program issuance / authentication server 11 for each event, and the user can download a unique cybercode generation program for each user and access a different authentication server for each event. be able to.

  In addition, the cybercode 241 displayed on the liquid crystal display 35 of the mobile phone 1 is recognized by the ticketless terminal 3, and the user is issued by the cybercode generation program issuance / authentication server 11 of the cybercode authentication site 8 via a network such as the Internet 7. Although described as performing authentication, the present invention is not limited to this, and the ticketless terminal 3 and the cybercode generation program issuance / authentication server 11 can be configured as one device.

  Furthermore, although the cyber code generation program has been downloaded to the mobile phone 1 and has been described as executing the program to display the cyber code, the present invention is not limited to this, for example, having a display function, In addition, it can be widely applied to devices such as portable personal computers, portable devices, PDA (Personal Digital Assistant), or PHS (Personal Handyphone System) that can execute cyber code generation programs (Java applets). it can.

  In addition, in the above, the cyber code generation program itself has a function as an authentication key, so that what is generated by executing the program may be an array of numbers, sounds, or patterns in addition to the cyber code. .

  In the above description, the cyber code displayed on the liquid crystal display 35 of the mobile phone 1 is used as an authentication cyber ticket. For example, on the download screen shown in FIG. When the item is selected, a cyber code generation program for generating an authentication coin that can be used as a substitute for a predetermined amount is downloaded from a user's account by accessing a predetermined bank where the user is trading. It may be. In this case, when the user purchases a desired article, the user displays an authentication currency (cyber code) on the liquid crystal display 35 of the mobile phone 1 in a vending machine or a shop terminal capable of recognizing a cyber code. When authenticated as described above, electronic settlement is executed.

  Furthermore, in the above, since various cyber code generation programs (Java (registered trademark) applets) are downloaded to the mobile phone 1, the storage capacity of the memory 86 becomes full. The authentication cyber ticket that has passed (already the concert has ended) is automatically deleted or the Java (registered trademark) applet execution screen shown in FIG. When the registered trademark applet is selected, a warning message such as “The program cannot be executed because the expiration date has passed” may be displayed on the liquid crystal display 35.

  As shown in FIG. 12, a recording medium for recording a program installed in a computer and executable by the computer includes a magnetic disk 211 (including a flexible disk), an optical disk 212 (CD-ROM (Compact Disc-Read). Packaged media consisting of only memory), DVD (Digital Versatile Disc), magneto-optical disc 213 (including MD (Mini-Disc) (registered trademark)), or semiconductor memory 214, or a program is temporarily or Consists of permanently stored Flash ROM and hard disk. The program is recorded on the recording medium using a wired or wireless communication medium such as the public line network 5, the local area network or the Internet 7, or digital satellite broadcasting via an interface such as a router or a modem as necessary. Done.

  In the present specification, the step of describing the program recorded on the recording medium is not limited to the processing performed in chronological order according to the described order, but is not necessarily performed in chronological order. It also includes processes that are executed individually.
