Description

  The present invention relates to an anti-counterfeit system, and more particularly, to an anti-counterfeit system capable of detecting a copy in a printed material, detecting falsification, and detecting an unauthorized leak source.

  As a technique for preventing forgery in conventional printed matter, there is a technique described in Patent Document 1. This technology prints an invisible image with halftone dots using black ink containing an infrared absorbing dye in rectangular areas arranged at equal intervals, and cyan around the invisible image area does not contain an infrared absorbing dye, This is a technique for printing at low cost an invisible image that cannot be viewed unless a special appraisal device such as an infrared camera is used, by printing with magenta and yellow primary inks of yellow.

  As a technique for converting handwritten characters and graphic data into digitized coordinate data and transmitting it to a predetermined device, there is a technique described in Patent Document 2. In this technique, by using a special electronic pen and a printed matter on which a dot pattern is printed, the trajectory of characters and figures written on the printed matter using the electronic pen can be stored and transmitted as vector data.

  The mechanism will be described with reference to FIG. A dot pattern 210 is printed on the entire surface of the print medium 201. The dots are printed for each lattice point at a constant interval, and the position is slightly deviated from the lattice point as shown in an enlarged view of a part of the dot pattern 210. The electronic pen 101 emits light from the light emitting diode 202 onto the printing surface of the dot pattern 210 and reads the dot pattern 210 with the built-in camera 203. As a result, the absolute coordinates of the position of the pen tip of the electronic pen 101 in the dot pattern space can be accurately specified. Further, the dot pattern space is divided into a predetermined size such as a standard for the paper size for easy management, and a dot pattern unique identifier (ID) is assigned to each section. The electronic pen 101 also outputs a dot pattern unique identifier of the read dot pattern 210.

  The electronic pen 101 includes a camera 203, an ink cartridge 204, a writing pressure sensor 205, a processor 206, a memory 207, a battery 208, and a communication device 209. The camera 203 reads a dot pattern only when the writing pressure sensor 205 is sensitive to pressure, and the processor 206 acquires pen tip position information. That is, the trajectory of characters and figures written on the print medium 201 is acquired as digital information. This digital trajectory information is accumulated in the memory 207 in time series, and is transmitted to a predetermined device by the communication device 209 at a certain timing.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. This embodiment exemplifies a prescription system that prints data on paper and uses it as a prescription.

  FIG. 1 shows the overall system configuration of the first embodiment. The prescription system 111 includes a prescription receiving apparatus 121 installed in each pharmacy and a prescription creation / management apparatus 131 installed in each hospital. In FIG. 1, only one prescription receiving apparatus 121 and one prescription creating / managing apparatus 131 are shown, but there may be a plurality of prescription receiving apparatuses 121 and prescription creating / managing apparatuses 131. The devices 121 and 131 are connected via the network 112, and data can be transmitted and received between the devices.

  In the prescription system 111, the patient brings the prescription 102 printed and created by the hospital prescription creation / management apparatus 131 to the pharmacy, and the pharmacy accepts the prescription by the prescription acceptance apparatus 121, and according to the prescription, Prescribe medication to the patient.

  The prescription creation / management apparatus 131 is a computer apparatus that creates prescription data and prints a prescription, and transmits / receives data to / from the prescription acceptance apparatus 121. In addition to the electronic pen 101, the prescription creation / management apparatus 131 includes an input device 132 such as a keyboard and a mouse, and an output device 133 such as a display and a printer as user interfaces.

The electronic pen 101 can be connected to the prescription receiving apparatus 121 by wire or wireless. The main body of the prescription receiving apparatus 121 is composed of a CPU, a memory, a communication device, a storage device, a control device for controlling data communication between them, and the like, and programs in the storage device are sequentially read and executed by the CPU. As a result, two processing units functioning as respective processing units function. That is, the prescription receiving unit 124 that receives a prescription using the electronic pen 101 and the prescription data comparing unit 125 that compares the prescription data received from the prescription creating / managing device 131 with the prescription data input from the input device 122 are operated. To do.

  FIG. 3 is a diagram illustrating a table configuration example of the prescription data table 138. The prescription data table 138 is a table for managing the dot pattern printed by the dot pattern printing unit 134 and the prescription data created by the prescription data creation unit 135 in association with each other. ”,“ Pharmacy ”and“ Prescription data ”. The “dot pattern ID” is a dot pattern unique identifier of the detected dot pattern. The “filled area” is coordinate data of a coordinate area on a dot pattern on which a fill mark described later is printed. The “pharmacy” is an identifier of the pharmacy where the coordinate data transmission source prescription receiving apparatus 121 that detects coordinate data from the electronic pen and transmits it to the prescription creation / management apparatus 131 is installed. “Prescription data” is prescription data including a patient name, a medicine name, the number of the medicines, and the like. Since the patient name becomes the distribution destination of the printed prescription, it also means the printing history.

  Hereinafter, the processing flow of the prescription system 111 will be described with reference to FIG. First, the prescription data creation unit 135 of the prescription creation / management apparatus 131 has a prescription 102 on which prescription data 502 such as a dot pattern, a fill mark 503, and a patient name as shown in FIG. Is created (step 401). At this time, the dot pattern printing unit 134 prints with a different ink from the dot pattern and the fill mark 503 printed around each dot so as to avoid each dot. In other words, the dot pattern is printed with ink that absorbs light emitted from the light emitting diode 202 of the electronic pen 101, and the fill mark 503 is printed with ink having transparency. Considering the difficulty of counterfeiting, the dot pattern and the fill mark 503 are preferably the same color. Here, for example, the light emitting diode 202 emits infrared light, the dot pattern is printed in black with carbon ink, and the fill mark 503 is printed in black with non-carbon ink.

  This prescription occupies a part of a vast dot pattern space. A unique dot pattern ID is associated with the area occupied by the prescription. Therefore, the dot pattern on the prescription is printed in a pattern that allows detection of the pattern ID assigned from any area.

  If the fill mark 503 is arranged so as to overlap the paper area where the dot pattern exists, the position, shape, and size thereof are arbitrary. The electronic pen 101 does not detect the fill mark 503 or the area occupied by it, but only detects the dot pattern existing in that area.

  The prescription data management unit 136 of the prescription creation / management apparatus 131 records the dot pattern ID of the dot pattern printed in step 401, the coordinate data of the fill area of the fill mark 503, and the prescription data in the prescription data table 138 in association with each other. (Step 402). For example, when the filled area is a rectangle, the coordinate values of the start point and end point of the area, or the coordinate value of the start point and the data such as width and height are used.

  Next, the hospital staff fills in the prescription 102 printed in step 401 with the name of the medicine 602 to be prescribed and the number 603 as shown in FIG. 6 with the electronic pen 101, and gives the prescription 601 to the patient. Since the ink cartridge 204 of the electronic pen 101 stores non-carbon ink, the character data on the prescription 601 is filled with non-carbon ink. The electronic pen 101 calculates the coordinate data and the dot pattern ID detected by the passage of the electronic pen 101 from the dot pattern at the entry location. A series of coordinate data that is the locus of the electronic pen 101 constitutes so-called vector data. The prescription data creation unit 135 of the prescription creation / management apparatus 131 receives the coordinate data and the dot pattern ID from the electronic pen 101 (step 403), and the corresponding dot pattern in the prescription data table 138 via the prescription data management unit 136. In the ID record, the coordinate data is recorded as a part of the “prescription data” (step 404). The coordinate data may be recorded in the “prescription data” as text data by recognizing characters. Alternatively, a series of coordinate data may be recorded in “prescription data” or a corresponding file as image data of handwritten characters.

  The patient brings the delivered prescription 601 to the pharmacy. The pharmacy staff enters a check 701 on the prescription 601 as shown in FIG. 7 using the electronic pen 101 connected to the prescription receiving apparatus 121. The electronic pen 101 calculates the series of coordinate data and the dot pattern ID from the dot pattern at the location where the check 701 is entered. The prescription receiving unit 124 of the prescription receiving apparatus 121 receives the coordinate data and the dot pattern ID from the electronic pen 101 (step 405). At this time, the electronic pen 101 can also read the dot pattern for the check entry on the fill mark 503 due to the difference in absorption and transmission of infrared light, and check 701 as shown in FIG. Can be obtained. However, if the prescription is copied, the fill mark is the same black under infrared light, so the copier can distinguish between the dot pattern and the fill mark when reading the fill mark part. Instead, it is printed with the same ink (carbon). For this reason, the electronic pen 101 cannot read only the dot pattern portion, and cannot acquire coordinate data related to the check 701 of the fill mark 503 portion like the coordinate data 802 shown in FIG. 8B.

  The prescription receiving unit 124 of the prescription receiving apparatus 121 transmits the coordinate data and the dot pattern ID received in step 405 to the prescription creating / managing apparatus 131 (step 406). It is assumed that the transmission destination is determined by the dot pattern ID.

  The prescription forgery determination unit 137 of the prescription creation / management apparatus 131 receives the coordinate data and the dot pattern ID (step 407). At this time, the prescription forgery determination unit 137 also acquires the identifier of the pharmacy as the transmission source. The identifier of the pharmacy may be an identifier unique to the prescription receiving apparatus 121 or an identifier unique to the electronic pen.

  Subsequently, the prescription data management unit 136 of the prescription creation / management apparatus 131 searches the prescription data table 138 using the dot pattern ID received in step 407 as a key, records the identifier of the pharmacy, Prescription data is acquired (step 408). The prescription data at this time generally includes at least one of character data of handwritten characters and print characters such as a patient name printed on a print medium. At this stage, the hospital can know at which pharmacy the patient has received the drug.

  The prescription forgery determination unit 137 of the prescription creation / management apparatus 131 determines whether the coordinate data of the filled area acquired in step 408 exists in the coordinate data received in step 407 (step 409). If it exists, the prescription forgery determination unit 137 determines that the prescription 601 has not been copied, and if not, determines that the prescription 601 has been copied (step 410). The prescription forgery determination unit 137 transmits the copy determination result and the prescription data acquired in step 408 to the prescription receiving apparatus 121 (step 411).

  The prescription data comparison unit 125 of the prescription receiving apparatus 121 receives the copy determination result and the prescription data, and displays them on the output device 123 such as a display (step 412). The pharmacy staff confirms the presence or absence of copying by looking at the displayed copy determination result, and compares the displayed prescription data with the prescription 601 to confirm the presence or absence of falsification. As a result, the pharmacy can detect copying and falsification of the prescription and does not prescribe medicine that should not be prescribed. Further, since the displayed prescription data includes the patient name, it is possible to know the recipient of the prescription and the outflow source of the copy.

  Further, tampering may be detected as follows. The prescription data comparison unit 125 inputs the contents of the prescription 601 from the input device 122 such as a keyboard or a scanner (step 413), compares the data with the prescription data received in step 412, and extracts a difference (step 414). The result is displayed (step 415).

  The copy determination in step 410 is not performed by the prescription creation / management apparatus 131, but the prescription acceptance apparatus 121 or the electronic pen 101 receives the information on the painted area from the prescription creation / management apparatus 131, and the prescription acceptance apparatus 121 or the electronic The pen 101 may do this.

  The determination of falsification in step 414 may be performed by the prescription preparation / management apparatus 131 by the prescription preparation / management apparatus 131 receiving the data input in step 413 from the prescription reception apparatus 121 instead of being performed by the prescription reception apparatus 121. .

  The electronic pen 101 connected to the prescription receiving apparatus 121 may not have a writing function. Even without a writing function, the electronic pen 101 can detect a series of coordinate data that is the locus of the check 701.

In addition to the electronic pen 101, the prescription preparation device 931 includes an input device 932 such as a keyboard and a mouse and an output device 933 such as a display as user interfaces. The main body of the prescription preparation device 931 is composed of a CPU, a memory, a communication device, a storage device, a control device for controlling data communication between them, and the like, and programs in the storage device are sequentially read and executed by the CPU. As a result, one processing unit serving as each processing unit functions. That is, the prescription data creation unit 934 that uses the contents entered in the electronic pen 101 on the prescription 902 as prescription data operates.

  The prescription receiving apparatus 921 is a computer apparatus that receives a prescription and transmits / receives data to / from the prescription management apparatus 941 and the prescription creating apparatus 931. In addition to the electronic pen 101, the prescription receiving apparatus 921 includes an input device 922 such as a keyboard and a scanner and an output device 923 such as a display as user interfaces. The main body of the prescription receiving device 921 is composed of a CPU, a memory, a communication device, a storage device, a control device for controlling data communication between them, and the like.

That is, a prescription receiving unit 924 that receives a prescription using the electronic pen 101 and a prescription data comparing unit 925 that compares prescription data received from the prescription management device 941 and prescription data input from the input device 922 operate.

  FIG. 10 is a diagram illustrating a table configuration example of the prescription data table 947. The prescription data table 947 is a table for managing the dot pattern printed by the dot pattern printing unit 944 and the prescription data created by the prescription creation device 931 in association with each other. The “dot pattern ID” and the “fill area” And “Hospital”, “Pharmacy” and “Prescription Data”. The “dot pattern ID” is a dot pattern unique identifier of the detected dot pattern. “Filled area” is coordinate data of a coordinate area on a dot pattern on which a filled mark is printed. “Hospital” is an identifier of a hospital from which prescription data is created. The “pharmacy” is an identifier of the pharmacy where the coordinate data transmission source prescription receiving apparatus 921 that detects coordinate data from the electronic pen and transmits it to the prescription management apparatus 941 is installed. “Prescription data” is prescription data including a patient name, a medicine name, the number of the medicines, and the like. Since the patient name becomes the distribution destination of the printed prescription, it also means the printing history.

  Hereinafter, the processing flow of the prescription system 911 will be described with reference to FIG. First, the dot pattern printing unit 944 of the prescription management apparatus 941 creates a paper 1204 on which a dot pattern and a fill mark 1203 as shown in FIG. 12 are printed (step 1101). At this time, the dot pattern printing unit 944 prints the dot pattern and the fill mark 1203 printed around each dot so as to overlap each dot or avoid each dot using different ink. That is, the dot pattern is printed with ink that absorbs light emitted from the light emitting diode 202 of the electronic pen 101, and the fill mark 1203 is printed with ink that has transparency. Considering the difficulty of counterfeiting, it is preferable that the dot pattern and the fill mark 1203 have the same color. Here, for example, the light emitting diode 202 emits infrared light, the dot pattern is printed in black with carbon ink, and the fill mark 1203 is printed in black with non-carbon ink.

  The prescription data management unit 945 of the prescription management apparatus 941 records the dot pattern ID of the dot pattern printed in step 1101 and the fill area of the fill mark 1203 in association with each other in the prescription data table 947 (step 1102).

  The medical association distributes the paper 1204 to each hospital.

  Next, the prescription data creation unit 934 of the prescription creation apparatus 931 creates a prescription sheet on which prescription data 1202 such as a patient name as shown in FIG. 12 is printed (step 1103). The hospital staff affixed the paper 1204 printed with the dot pattern and the fill mark 1203 received from the medical association on this paper, and enters the name of the medicine to be prescribed and the number of the medicines on the paper 1204 with the electronic pen 101. Give the prescription to the patient. The electronic pen 101 calculates coordinate data and dot pattern ID detected by the passage of the electronic pen 101 from the dot pattern of the entry location. The prescription data creation unit 934 of the prescription creation device 931 receives the coordinate data and the dot pattern ID from the electronic pen 101 (step 1104) and associates them with the prescription data (patient data, etc.) printed in step 1103, It transmits to the management apparatus 941 (step 1105). The acquired coordinate data is a part of the prescription data. The coordinate data may be text data by character recognition. Alternatively, a series of coordinate data may be converted into handwritten character image data. As a method of associating with the prescription data, the dot pattern ID received from the electronic pen 101 immediately after step 1103 may be used, or the dot pattern ID may be input from the keyboard.

  The prescription data management unit 945 of the prescription management apparatus 941 receives the dot pattern ID and prescription data (step 1106). At this time, in addition to the prescription data shown in the first embodiment, the identifier of the sender hospital is also acquired. The identifier of the hospital may be an identifier unique to the prescription creation apparatus 931 or an identifier unique to the electronic pen.

  Subsequently, the prescription data management unit 945 of the prescription management apparatus 941 records the prescription data and the hospital identifier in the prescription data table 947 using the dot pattern ID received in step 1106 as a key (step 1107).

  The subsequent steps 1108 to 1118 are the same as steps 405 to 415 in the first embodiment. Accordingly, it is possible to check the combination and amount of medicines when a patient uses a plurality of hospitals and a plurality of pharmacies.

  In the above description, the prescription system is taken as an example. However, the present invention can be applied to any print medium that is visually recognizable and needs to prevent counterfeiting. For example, in a traceability system for agricultural products and industrial products, a dot pattern and a fill mark are printed on a label attached to the product, and a producer's signature and article name are written there, and a check is made at each mobile site. You can trace entries and travel routes. Even if the label is copied and attached in order to pretend to be a copy product, it can be detected. Further, in the secret document management system, it is possible to perform copy detection and unauthorized leak source detection by printing a dot pattern and a fill mark together with the secret document.
