Description

  The present invention relates to a card having a dot pattern formed on the surface and a security system using a seal.

In order to prevent tampering or duplication of memory stored in the product or card, read only ROM (Read Only
There is a technique in which an IC package with a built-in memory is sealed with a seal sticker, or an IC is sealed with a resin laminate like a non-contact card.

  However, in the case of the seal sticker as described above, a complicated pattern, a watermark, or the like has been applied to the seal in order to make it difficult to reproduce. However, due to the widespread use of high-precision color copiers, duplication is becoming easier. Security on seals has not been fully secured.

  Furthermore, in the case of a non-contact card, since the ROM is sealed in a non-contact state with the outside, it can be said that the security is high, but there is a problem that the manufacturing cost is high. In this regard, the conventional magnetic card has a problem that it is easy to read the magnetic part, although the manufacturing cost is low.

  Thus, it has been required to establish a technique for ensuring the security of data stored in a medium.

  This invention is made | formed in view of such a point, and makes it a subject to provide the security system which can ensure high security cheaply.

  In order to solve the above problems, the present invention employs the following means.

It is.

  By printing a dot pattern on a medium and using this dot pattern as an authentication code, a simple, inexpensive and high security system can be constructed.

  According to a second aspect of the present invention, “the medium is a printed seal, and the dot pattern is visually invisible with a carbon ink having the same color as the print surface on a print surface applied with a non-carbon ink. The security system according to claim 1, wherein the dot pattern is printed and the reading unit optically reads the dot pattern which is invisible by receiving reflected light from the printed surface irradiated with infrared rays. It is.

By printing the dot pattern with a carbon ink that is visually the same color as the printing surface on the printing surface of the seal surface that has been coated with non-carbon ink, the user is not aware of the presence of the dot pattern. Therefore, a seal with improved security can be provided. As a seal, besides a normal paper seal, a thin plate seal made of a synthetic resin may be used.

  According to a third aspect of the present invention, “the medium is a printed card, and the dot pattern is visually invisible with a carbon ink having the same color as the printed surface on a printed surface applied with a non-carbon ink. The security system according to claim 1, wherein the dot pattern is printed and the reading unit optically reads the dot pattern which is invisible by receiving reflected light from the printed surface irradiated with infrared rays. It is.

  According to a fifth aspect of the present invention, “the issuing terminal of the medium having a printing surface printed with at least non-carbon ink, the authentication code generating means for generating the authentication code, and the same color visually on the printing surface of the medium” Printing means for printing an invisible dot pattern corresponding to the authentication code generated in the above, and registration means for registering the authentication code of the dot pattern printed in the authentication table as a true value in the authentication table Issuing terminal of the medium to become. "

  By printing the dot pattern directly at the time of media provision at the issuing terminal, the dot pattern is provided to the user for the first time, so it becomes difficult to duplicate or analyze the dot pattern in advance, and security can be improved. .

  According to a sixth aspect of the present invention, "the issuing terminal includes an encryption filter unit, and the authentication code generated above is converted into a replacement code by the encryption filter, and then a dot pattern corresponding to the replacement code" 6. The medium issuing terminal according to claim 5, wherein the medium is printed as a dot pattern that is converted into an invisible dot pattern by a printing unit.

  By generating a dot pattern for printing by converting the code using an encryption filter, it is difficult to analyze the true value code (authentication code) simply by obtaining the dot pattern for printing. Can be further enhanced.

  Claim 7 of the present invention is as follows: “The issuing code authentication means of the issuing terminal has an issuing time specifying table capable of specifying the issuing time of the generated authentication code. Terminal. "

  By making it possible to specify the issuance time of the authentication code, it becomes possible to grasp the authenticity of the code from the issuance time.

  Claim 8 of the present invention is "the medium issuing terminal according to any one of claims 5 to 7, wherein an expiration date can be set for each authentication code in the authentication table."

  By providing an expiration date for the authentication code, unauthorized use of the code after a certain expiration date can be prevented.

The security system according to claim 1, wherein the permission signal is outputted from the output means only when it is arranged.

  Since the reading means can recognize the angle of the dot pattern at the time of reading, the reading code can have different meanings depending on the arrangement position of the medium. Therefore, the arrangement of the medium is sequentially changed to read different codes. It becomes possible to make it. As such a dot pattern, for example, the angle of the dot pattern with respect to the reading device can be grasped by the positional relationship between the key dot provided inside or outside the dot pattern and the center of the dot pattern.

  According to a tenth aspect of the present invention, “a reading unit that optically reads at least a predetermined dot pattern formed on a surface of a medium, a conversion unit that converts a dot pattern read from the reading unit into a code, An authentication table for registering a corresponding true value, a determination unit for comparing the code obtained from the conversion unit with a true value read from the authentication table and determining a true value, and an output for outputting a determination result of the determination unit "A scanner consisting of means."

It becomes possible to prevent the distribution of merchandise and merchandise for criminal purposes.

  Embodiments of the present invention will be described with reference to FIGS. Note that the circled numbers in the drawings are <1> for convenience in this specification.

  FIG. 1 is a block diagram illustrating a functional configuration of the reading apparatus.

  The reading device can irradiate a medium with infrared rays as irradiation light, and has a built-in C-MOS camera (C-MOS sensor) that reads reflected light from the medium.

  As shown in FIG. 2, a print layer printed with a non-carbon ink on the surface of the medium and a dot layer printed with a carbon ink are provided on the print layer.

  The carbon ink constituting the dot has a characteristic of developing a color in the infrared wavelength range (characteristic of reflecting infrared rays), and the non-carbon ink absorbs the infrared wavelength range, so that a dot pattern is captured by a C-MOS camera. Recognition becomes easy.

  Since the same color is used for the print layer (non-carbon ink) and the dot layer (carbon ink), the dot layer on the print layer of the medium cannot be recognized by human eyes.

  The dot pattern read by the C-MOS camera of the reading device is converted into a code (reading code) by the code conversion unit.

  The read code is converted into a read true value code by the encryption filter and transmitted to the determination unit.

  The determination unit reads the true value code stored in the authentication table and compares it with the read true value code. And when a comparison result is the same value, it outputs as a true value code (TRUE) from a determination result output part. If the comparison results do not match, an error code (FAULT) is output. In the case of authenticity (TRUE), “OK”, “TRUE” or the like may be displayed on the display device, or sound such as “correct code” may be output from the speaker.

  The authentication table has a structure as shown in FIG. 4, which will be described later.

  Next, the principle of the dot pattern used in the present embodiment will be described with reference to FIGS.

  The dots represent numerical values by arrangement positions with lattice points assumed in the XY directions at regular intervals. In FIG. 5 and FIG. 10, lattice points are displayed for convenience of explanation, but these lattice points are virtual points and do not exist on the actual print surface.

  In the case of FIG. 5, for example, a dot arranged in the + X direction or the + Y direction with respect to the grid point means “1”, and a dot arranged in the −X direction or the −Y direction means “0”. .

  On the other hand, in FIG. 10, with respect to the lattice point, the dot arranged in the + Y direction is “0”, the dot arranged in the + X direction is “1”, the dot arranged in the −X direction is “2”, and −X. The dots arranged in the direction may be defined to mean “3”. In this way, four numerical values “0” to “3” can be expressed around the lattice point.

  Note that eight numerical values can also be expressed by arranging them in the diagonal direction of the lattice points. Furthermore, twelve numerical values can be expressed by the angle in the oblique direction.

  FIG. 11 illustrates a process of converting a dot pattern code in which dots representing “0” to “3” as described above are arranged into a true value code using the encryption filter described in FIG.

  In the figure, not the dot pattern itself but the numerical value which each dot means for convenience. As shown in the figure, a true value code can be obtained by performing arithmetic processing by a cryptographic filter (addition type) on the code value read from the dot pattern. The encryption filter is provided as a recording medium such as a cartridge such as a ROM, and is detachably attached to the reading device. By periodically exchanging the encryption filter, unauthorized use can be suppressed only within a certain period even when the dot pattern is copied from the sticker attached to the medium.

  FIG. 3 is a block diagram showing a device configuration of the issuing terminal and a connection configuration between the server and the reading device.

  The issuing terminal has a printing unit using a laser printer or an ink jet printer system, and can print a dot pattern with carbon ink. In addition, the printing layer by the non-carbon ink shown previously in FIG. 2 is formed on the medium.

  The authentication code generation unit generates an authentication code based on time information from a clock (CLOCK). Since this authentication code is generated in the issuing terminal by performing a predetermined function calculation from the clock, it is not known what type of authentication code will be before this generation. The authentication code generated in this way is registered in the authentication table in the issuing terminal, converted into a dot code for printing by the encryption filter, and generated as a dot pattern for printing by the dot pattern generation unit, and the printing unit is Printed on the surface of a medium such as a seal.

  Data (authentication code) of the authentication table in the issuing terminal is transmitted to the server via the communication line. In the server, the received authentication code is registered in an authentication database (DB).

  The server transmits the authentication code of the authentication database (DB) to the authentication table of the reading device via the communication line.

In this way, the authentication code (true value code) is registered in the authentication table of the reading apparatus, and the authenticity of the reading code from the dot pattern can be determined.

  As shown in FIG. 4, “authentication code”, “issue terminal ID”, and “expiration date” are registered in the contents of the authentication table and the authentication database (DB). The “true code” is the authentication code itself generated by the issuing terminal, and the “issuing terminal ID” is an ID assigned to the issuing terminal shown in FIG. Also, by registering “expiration date” in this authentication table and authentication database (DB), even if the dot pattern conversion result read by the reading device is a true value on the authentication table, the expiration date has expired. Can also be processed. Further, the true value code itself may be deleted from the authentication table or the authentication database (DB) when the expiration date has passed.

  In FIG. 3, the authentication table is described in the case where the authentication table is provided in both the issuing terminal and the reading device. However, an authentication database (DB) is provided only in the server, and the reading device reads the code read from the dot pattern or the converted data. The server may be notified of the code, and the server may determine the authenticity of the code based on the authentication database and return the result to the reading device.

  In the dot pattern, as shown in FIG. 6, a “key dot” is arranged above the dot pattern, and the orientation of the dot pattern can be recognized by the arrangement relationship between the key dot and the center point.

  For example, in FIG. 7, the dot pattern is arranged at a rotation position of −15 degrees, and in FIG. 8, the dot pattern is arranged at a rotation position of +90 degrees.

  From this, the dot pattern is printed on the surface of the card, and the reading dot pattern has a different meaning by placing the card at a predetermined angle with the card surface as a horizontal plane and its vertical axis as the rotation axis center. Can be made. For example, as shown in FIG. 9, it is possible to read additional different information (0, 5, and 2 depending on the angle) other than the dot pattern read depending on the reading angle. By adding the numerical value of such angle information to the end of the dot pattern, the same dot pattern can be further developed into a plurality of codes. For example, when the code of the dot pattern read from the surface of the card is “0123”, it can be recognized as “01230” → “01235” → “01232” depending on the card arrangement angle of FIG.

  In this way, by determining the order of the angular arrangement and not determining the true value if the arrangement order is not correct, even if the dot pattern displayed on the card is single, security is further increased. Can be increased.

  In addition, by using the card shown in FIG. 9 as a trading card and forming a dot pattern on the surface of the trading card, it is possible to output different voices and conversation contents by changing the orientation on the reader. Is also possible.

  12 to 16 exemplify media on which a dot pattern is formed.

  FIG. 12 is an example in which a dot pattern is printed on a sticker attached to a product package. Examples of the product package include computer software, game software, music CD, DVD software, and the like.

  FIG. 13 shows an example in which a dot pattern is printed on the product itself. Any product may be used as long as it can be printed on the surface.

  FIG. 14 shows an example in which a dot pattern is printed on the surface of a card or sticker. Examples of the card include a magnetic card having a magnetic layer formed on the back surface, a magnetic stripe card, an IC card, and a plastic card, and examples of the seal include a paper card having an adhesive layer on the back surface.

  Non-contact commuter pass, boarding ticket, credit card, game card, trading card, pachinko game card, identification card, ID card, passport, medicine wrapping paper, medicine bottle content display sticker, Etc. can be illustrated. Further, the supplier product such as wrapping paper and packaging film of the medicine can be prevented from being illegally supplied by forming this dot pattern on the supply roll.

  FIG. 15 shows an example in which a dot pattern is formed on a sealing sticker, which is used for sealing an IC chip or the like, and the sealing sticker itself may be any paper medium, synthetic resin, or metal.

  In FIG. 16, a dot pattern seal is attached to the surface of a plastic belt (wristband), and the patient may be able to recognize himself / herself by wearing it on an arm or leg in a hospital or the like. In that case, a doctor, nurse or pharmacist carries a pen-type reading device and reads the dot pattern on the surface of the patient's plastic belt with the pen-type reading device at the time of treatment or medication. Can be prevented.

  In addition, an issuance terminal is installed in the delivery room at the time of delivery of the newborn, and the mother and the newborn can be reliably associated with each other by issuing a sticker attached to the belt to the mother and the newborn at the time of delivery. It is possible to prevent misunderstanding accidents.

  FIG. 17 shows a configuration in which reading devices are connected via a network (NW).

  A child, an elderly person, or a disabled person possesses a card on which a dot pattern is formed, and reads the dot pattern on the card with a reading device provided at the destination or at home. A speaker is attached to the determination result output unit of the reading device, and when the authentication code is a true value by the determination, a sound such as “OK” or “Let's do our best today” is output. It has become so. Such audio data can be registered in advance by the family through a microphone in a memory (not shown) of the reader.

  When it is determined that the authentication code read from the card by the determination unit is a true value, the sound is output from the speaker and is registered in the reader in advance via the network (NW) and the base station. It is notified to the mobile phone terminals owned by the family so that the arrival of the card holder, the elderly, and the handicapped person at the destination and return home can be grasped. Note that the notification to the mobile phone terminal may be an email notification in addition to a voice notification.

  At this time, the audio content to be output may be changed depending on the position (angle) at which the card is placed with respect to the reading device as described with reference to FIGS.

  FIGS. 18 to 26 are embodiments in the case where the present invention is applied to the correctness / incorrectness determination of products using a scanner, and FIGS. 49 to 52 are diagrams showing configurations of a sensor unit and a scanner.

The internal structure of the scanner is as shown in FIG. 50. The input data from the C-MOS sensor is accumulated, and a determination table (authentication table) described later, a memory for registering various programs, and data from the memory are read and processed. It has a CPU (Central Processing Unit), a display LED for displaying the determination result, a power supply for supplying driving power, a power switch, and the like. This power switch may be one that is controlled to be turned ON / OFF in conjunction with the pressing operation of the sensor unit. In this case, the opening of the sensor unit of the scanner may be pressed against a medium on which a dot pattern such as a seal is formed and then clicked to turn on the power switch to read the dot pattern.

  FIG. 27 shows the contents of a determination table (authentication table) provided in the memory.

  Further, while having the same configuration, the configuration may include a speaker as shown in FIG. 51 and a liquid crystal monitor as shown in FIG. In the case of FIG. 51, the correctness / incorrectness determination can be performed by utterance from the speaker, and in the case of FIG.52, the correctness / incorrectness determination can be performed by displaying on the liquid crystal monitor.

  In this embodiment, using a scanner as shown in FIG. 40, the dot pattern formed on the surface of the seal affixed to the bottle body and the cap of a plastic bottle (product) into which drinking water has been injected is read. It is determined whether or not the product is genuine. It is used to prevent crimes that occur when drinking water is replaced with toxic liquids and left unattended.

  FIG. 50 schematically shows a scanner used in this embodiment. As shown in FIG. 49, the tip portion of the scanner is irradiated with IRLED light reflected from the inner surface of the light guide through the opening at the tip of the cover.

  Then, the irradiation light irradiated from the opening reflects the surface of a medium (such as a seal) on which a dot pattern is formed, and the reflected light enters the sensor unit from the opening to pass the lens and the IR filter. Via, it is optically read by the C-MOS sensor.

  The dot pattern image data read by the C-MOS sensor is temporarily stored in the memory shown in FIG. 50, and then analyzed by the CPU and converted into a dot code.

  FIG. 18 is a processing flow (type A) showing the entire processing procedure of correct / incorrect determination of a product using the scanner. In this example, the company code and the judgment dot code are registered in advance in the scanner memory. Here, the company code to be registered in the scanner is one, and the company code is registered when delivering to the company. It can be made unusable for other purposes. Since multiple determination dot codes can be registered for each table, each time a scanner is used for product correctness determination, a table in which the determination dot code is registered is selected, and it is easy to determine different dot codes each time. become. By defining the determination dot code with a classification code and an identification code, it is possible to set three determination modes: <1> determination with only the classification code <2> determination with only the identification code <3> determination with both. As a result, various security seals can be classified and issued and determined.

  In the figure, when processing is started (1801), a company code is registered in the scanner (1802). Specifically, this is performed by reading the company code registration sheet shown in FIG. 44 with a scanner. A dot pattern is formed on this company code registration sheet, and a predetermined dot pattern is formed in each area of “dot click”, “code input”, “registration”, “1” to “0” by printing or the like. Has been. This dot pattern is read by the scanner and stored in the memory as image data. Then, the image data is read from the memory by the CPU, converted into a company code as shown in FIG. 19 based on a predetermined algorithm, and registered in the registration table of the memory.

  In the processing flow shown in FIG. 18, one or more determination dot codes are registered in each determination dot code registration table by the scanner (1803). The registration of the determination dot code is performed by reading a predetermined area of the determination dot coat registration sheet shown in FIG. FIG. 19 shows the format of the company code and the judgment dot code. These company code and determination dot code are stored as a series of codes, for example, 7-digit numbers. In this case, the first two digits may mean a company code, the next one digit may mean a product classification code, and the subsequent four digits may mean a product identification code. The identification code may be used for the issue date, serial number, and password of the code. Specifically, in the case of the code “0110324”, the company code = 01, the classification code = 1, and the identification code = 0324.

  Specifically, such a code is set in a determination dot code registration table (authentication table) shown in FIG. In the figure, a determination dot code is registered for each table number. One determination dot code is registered in table number 1, two determination dot codes are registered in table numbers 2 and 3, and four determination dot codes are registered in table number 4. In the determination table, a determination mode is registered for each table number. A determination dot code corresponding to the mode number is registered in the determination mode table.

  Next, one or a plurality of determination dot code registration tables to be determined are selected and one of the three determination modes is set (1804). Specifically, this is performed by reading a predetermined area of the determination dot code registration sheet shown in FIG. 45 with a scanner.

  Finally, the security sticker affixed to the bottle and cap as described above is clicked (read) with a scanner, the dot code printed on the security sticker is read, and the determination dot code set in step 1804 is verified. Then, correct / incorrect is determined (1805), and the process is completed.

  FIG. 20 is a flowchart showing the registration procedure of the company code. The outline of this flowchart will be explained. The company code is registered using the company code registration sheet of FIG. 44, and the company code registered when the dot code printed on the security seal is determined, and the company in the dot code. If the codes are collated and they are different, an error occurs.

  First, a company code is registered (2001). Here, the “dot click” area of the company code registration sheet shown in FIG. 44 is read (clicked) (2002). Next, the company code is clicked and the company code is input (2003). Then, the company code is registered in a table provided in the scanner memory by clicking on the “Register” area (2004).

  On the other hand, when “code input” is clicked (2005), a decimal company code may be input by clicking “0” to “9” (2006).

  If the company code has already been registered in the table (2007), the red LED lights up or “company code already registered” is displayed on the LCD monitor and “registration” is clicked again within 5 seconds. The green LED blinks or “Company code registration completion” is displayed on the liquid crystal monitor, and the company code is updated and registration is completed (2008).

  On the other hand, if the company code is not registered, the green LED blinks or “Company code registration completed” is displayed on the liquid crystal monitor, and the registration of the company code is completed (2009). In this way, the registration of the company code is completed (2010).

  21 to 22 are flowcharts showing the determination dot code registration procedure. In the figure, determination dot codes are registered in the respective tables in the memory using the determination dot code registration sheet shown in FIG.

  First, in the determination dot code registration sheet table number selection process (2101), after clicking “input” with the scanner, “0” to “9” are clicked to input the table number (2102). Next, click “Select” to select the table number (2103). When selected, the green LED lights up or the table number and “Select Table Number” are displayed on the LCD monitor, and the table number is selected. (2104).

  On the other hand, when canceling the table number, click “Release” to cancel the determination dot code already set in the table (2110). The table number and “determination dot code release” are displayed (2111), and the process ends (2112).

  Next, in the determination dot code registration procedure (2105), "dot click" is clicked (2106). Then, the dot on which the determination dot code is printed is clicked, and the determination dot code is input (2107). In addition, the determination dot code may be registered by clicking “code input” (2108) and then clicking “0” to “9” to input the determination dot code (decimal number) (2109).

  Next, when a determination dot code is added and registered in the table (2201), the processing from step 2106 or 2108 is repeated.

  If no additional registration is to be performed, “registration” is clicked to register one or more determination dot codes (2202). At this time, if the determination dot code has already been registered (2203), the red LED lights up or “determination dot code already registered” is displayed on the liquid crystal monitor and “registration” is clicked again within 5 seconds. The LED blinks or “determination dot code registration completion” is displayed on the liquid crystal monitor, and the determination dot code is updated and registration is completed (2204).

  On the other hand, if the determination dot code is not registered, the green LED blinks or “determination dot code registration completion” is displayed on the liquid crystal monitor, and the determination dot code registration is completed (2206).

  In this way, registration of the determination dot code is completed (2205).

  23 to 24 are flowcharts showing the determination mode setting procedure.

  Here, in order to collate with the dot code printed on the security sticker with the determination dot code registered in the memory table, the determination dot code table number and the determination mode are set. The determination mode can be set for each table number, a plurality of tables to be used for determination can be set, and at the same time, determination can be made with dot codes registered in a plurality of tables.

Specifically, in the table number selection / cancellation process (2301), after clicking “input” of the determination mode setting sticker shown in FIG. 46, the table number is input by clicking “0” to “9”. (2302). Next, “select” is clicked, and a registration table for setting the determination mode is selected (2303). When selected, the green LED is turned on or the table number and “Registered table selection” are displayed on the liquid crystal monitor, and the table number is selected (2
304). Then, the process proceeds to determination mode setting (2305). On the other hand, when canceling the determination mode, the user clicks “cancel” to cancel the already set table (2306). When released, the green LED is turned on, or the table number and “release registered table” are displayed on the liquid crystal monitor, and the determination of the dot code registered in the table is not performed (2307).

In the determination mode setting (2305), one of the steps in FIG. 24 is executed. That is, in step 2401, a “classification code” is clicked and a dot is determined based on the classification code in the determination dot code, and the green LED blinks or “classification code setting” is displayed on the liquid crystal monitor. Step 2402 is a mode in which the “identification code” is clicked to determine a dot by the identification code in the determination dot code, and the green LED blinks or “identification code setting” is displayed on the liquid crystal monitor. Further, in step 2403, the “classification & identification code” is clicked to enter a mode for judging dots based on all the judgment dot codes, and the green LED blinks, or “classification & identification code setting” is displayed on the liquid crystal monitor. In this way, each determination mode is registered in the scanner table (2404).

  25 to 26 show the determination procedure of the dot code.

  Here, while the scanner is touching the security seal, the dot code imaging / analysis is repeated until the determination dot code is verified even if an error is detected.

  First, in the dot code determination procedure (2501), the security seal is clicked with a scanner (2505). Here, as the security seal, in addition to the seal affixed to the drinking water plastic bottle and cap shown in FIG. 40, the seal for sealing the packing box shown in FIG. 41 may be used. Further, although described as a representative, the concept of the seal may include an admission permit as shown in FIG. 42 and that in which a dot pattern is formed on a binding band shown in FIG.

  The seal (security seal) can be generated through the process shown in FIG. First, a transparent seal having an adhesive layer on the back surface is prepared. A colored sheet such as silver is interposed between the transparent seal and the adhesive layer on the back surface, and when peeled from the surface of the product, only the colored sheet remains on the surface of the product in a predetermined shape. The evidence that the seal itself has been peeled off remains on the product side.

  A dot pattern is printed on the surface of the transparent seal, and a white layer is provided above the dot pattern. This white layer is for preventing the pattern printed on the upper layer from being seen through and making the lower layer dot pattern invisible. The white layer may be a laminate of white laminate films, or may be applied with white ink. Furthermore, not only white but any color may be used.

  The pattern is printed on the surface of the white layer. This symbol may be any picture such as a character, symbol, or character.

When determining the dot code, first, the security sticker is clicked with a scanner (2502), and the dot code printed on the sticker is photographed with a C-MOS sensor (2503). This photographing data is stored in a memory. Then, the CPU reads out the image data from the memory, and performs dot detection (2504), dot code analysis (2505), and company code verification (2506). At this time, if no dot is detected, “no input” is displayed on the liquid crystal monitor as to whether no LED responds (2507). If the dot code cannot be analyzed, the red LED is lit for 2 seconds and the buzzer sounds “buzz”, or “analysis impossible” is displayed on the liquid crystal monitor (2508). Further, if the company code cannot be verified, the red LED blinks for 2 seconds and “buzz” sounds, or “company code error” is displayed on the liquid crystal monitor together with the read company code (2509).

  If the company code can be verified, it is determined according to the determination mode whether the determination dot code has been verified (2601). Here, if the collation is successful, the green LED blinks for 2 seconds and “Peep” is uttered, or the character “collation” is displayed on the liquid crystal monitor together with the determination dot code (2602). On the other hand, if the verification cannot be performed, the red LED and the green LED are alternately blinked for 2 seconds to say “boo”, or “dot code error” along with the read determination dot code on the liquid crystal monitor. Is displayed (2604).

  Next, it is determined whether or not a registration table is additionally set in the determination box (3407). In the case of additional setting, the processing after step 3306 in FIG. 33 is repeated. If no additional setting is made, the process ends (3408).

  36 to 38 show the dot code determination procedure in Type B. FIG.

  In the dot code determination (3601), first, the security sticker is clicked with a scanner (3602), and the dot code printed on the sticker is photographed with a C-MOS sensor (3603). This photographing data is stored in a memory. Then, the CPU reads out the photographed data from the memory, and performs dot detection (3604), dot code analysis (3605), and company code verification (3606). At this time, if no dot is detected, “no input” is displayed on the liquid crystal monitor as to whether no LED responds (3607). If the dot code cannot be analyzed, the red LED is lit for 2 seconds and the buzzer sounds “buzz”, or “analysis impossible” is displayed on the liquid crystal monitor (3608). Further, if the company code cannot be verified, the red LED blinks for 2 seconds and sounds “buzz”, or “company code error” is displayed on the liquid crystal monitor together with the read company code (3609).

  Next, the CPU (central processing unit) determines whether or not the determination dot code set in the determination box <1> has been collated (3701). If it can be determined here, the green LED is lit for 2 seconds. Then, “Peep” is uttered or “verification” is displayed on the liquid crystal monitor together with the determination box number and the determination dot code (3702).

  Next, it is determined whether or not the determination dot code set in the determination box <2> has been verified (3703). If it can be determined here, the green LED blinks twice in 2 seconds to say “beep”, or “verification” is displayed on the liquid crystal monitor together with the determination box number and the determination dot code (3704).

  Further, when the collation can be made in the judgment box <5> (3709), the red LED blinks twice every two seconds and “bibi” is uttered, or “verification” is displayed on the liquid crystal monitor together with the judgment box number and the judgment dot code. It is displayed (3710).

  Further, when the collation can be performed in the judgment box <6> (3801), the red LED blinks three times for 2 seconds and “bibibit” is uttered, or “verification” is displayed on the liquid crystal monitor together with the judgment box number and the judgment dot code. It is displayed (3802).

  If none of the judgment boxes <1> to <6> can be collated, the red LED and the green LED blink alternately three times every 2 seconds and say “boo”, or the judgment box number is displayed on the LCD monitor. "Dot code error" is displayed together with the determination dot code read (3803), and the process is terminated (3804).

  Although the present invention has been described above, the present invention can also be used for correct / incorrect determination of a cash prize at a game hall as shown in FIG.

  For example, a security sticker on which a dot pattern is printed or a dot pattern is directly printed on a part of the cash prize, and this is read by a scanner to register that a cash prize has occurred on the in-store server. This is done by registering the code number of the dot pattern of the cash prize in the server as an authentication table.

  When the cash prize is taken out of the store and redeemed at the prize exchange, the dot pattern is read by a prize reader equipped with an optical scanner. Then, the code number converted from the dot pattern is transmitted from the terminal (PC) of the gift exchange office to the store server via the network. The in-store server compares the code number registered above with the code number received from the terminal (PC), makes a correct / incorrect determination (authentication), and returns the output to the prize reader. If the authentication is correct, the prize reader will continue the process, and if the authentication is incorrect, an alarm such as a buzzer is generated because there is a possibility that the authentication is incorrect.

  FIG. 54 shows whether a dot pattern is printed on a card such as a credit card, and the dot code obtained by converting the dot pattern read by the card reader matches the dot code registered in the management server. This is a case where correct / incorrect determination is performed.

  The present invention can be applied to a security technique using a card or a seal.
