  According to the adapter device of the present invention, a camera-equipped mobile terminal device can be used for authenticity determination of a random pattern on an object surface.

First, a pattern matching key photographed using the adapter device of the present invention will be described.
1A and 1B are diagrams for explaining a pattern matching key. FIG. 1A illustrates a fiber pattern of paper, FIG. 1B shows a pattern matching key made of paper, and FIG. ) Indicates a pattern matching key made of a plastic or silver painted surface.
As illustrated in FIG. 1A, the paper is made of intricately intertwined plant fibers. The width of the plant fiber is generally 4 to 70 μm, 10 to 50 μm for plain paper made from hardwood, and 20 to 70 μm for plain paper made from conifer.

  The use of a random pattern such as plant fibers contained in paper as a “fingerprint” for identifying each paper is also referred to as a PFP (Paper Finger Print) technique. Note that the PFP technique can be applied not only to paper but also to an object having a random pattern, such as a blasted metal plate or a silver-coated plastic plate.

  The pattern matching key uses a random pattern formed in this manner as a key. As shown in FIGS. 1B and 1C, the pattern verification key has a random pattern of paper, plastic, or silver paint. The pattern matching key shown in FIG. 1B has a paper fiber pattern as a random pattern. A random pattern portion (also referred to as a PFP registration unit) to be identified is included in at least a part of the card key, and has an area of 1 to 2 mm square. Since it is sufficient that a PFP registration part (1 to 2 mm square area) is secured in any part of the card key, the degree of freedom in designing the entire card key becomes very high and the card key can be easily downsized. It is.

  Whether the pattern verification key is genuine or a fake is determined by a pattern verification lock system to be described later. When it is determined that the pattern matching key is genuine, either the unlocking or locking of the pattern lock device storing the random pattern that matches the random pattern of the pattern matching key is performed.

  Since it is difficult to intentionally reproduce the paper fiber pattern, each of the pattern matching keys can be identified with extremely high accuracy, and its forgery is extremely difficult. In addition, the pattern matching key including the paper fiber pattern can be easily manufactured, and the cost for the manufacturing and maintenance is low.

  When such a pattern matching key PFP registration part is photographed with a camera-equipped mobile phone, the influence of ambient light cannot be controlled, and the PFP registration part has a uniform color (for example, white for paper, surface Since the processed metal is silver, the shadow of the random pattern cannot be created (if it is paper, it will be a uniform white surface), and the shadow direction and density, etc. It may be different from pre-registered verification patterns. For this reason, the PFP registration unit cannot be read appropriately by simply increasing the resolution of the camera.

Next, the adapter device 2 according to the first embodiment of the present invention will be described.
FIG. 2 is a diagram showing the adapter device 2 according to the first embodiment of the present invention. FIG. 2 (A) shows the configuration of the adapter device 2, and FIG. 2 (B) shows the adapter device 2. The case where it is mounted on the terminal device 4 is illustrated.
As shown in FIG. 2A, the adapter device 2 according to the present embodiment is provided with an opening 200 for mounting on a camera (not shown), a shielding member 202 that blocks ambient light, and an inner side of the shielding member. And a light source 204 for irradiating light onto an object photographed through the opening. The adapter device 2 may further include an optical system 206 provided on the optical axis of a lens unit (not shown) of the camera attached to the opening 200. With these configurations, the adapter device 2 according to the present invention can adjust the optical conditions suitable for photographing the random pattern simply by being mounted on the mobile terminal device.

  The opening 200 is a mount mechanism for the adapter device 2 to be detachably attached to the camera, and is connected to at least one of the camera, the lens portion of the camera, and the mobile terminal device main body. When the opening 200 is attached to the camera, the photographing object is photographed by the camera through the opening 200.

  The shielding member 202 is made of, for example, plastic, metal, etc., and shields ambient light on the object to be photographed. When photographing the PFP registration unit 8 of the pattern matching key 6, the shielding member 202 blocks ambient light to the PFP registration unit 8.

  The light source 204 is one or more LEDs, for example, and is provided so as to irradiate light in a direction different from the normal direction of the object surface to be imaged. For this reason, the uneven shadow of the random pattern in the PFP registration unit 8 of the pattern matching key 6 is appropriately formed and can be read by a video device such as a CCD. Furthermore, since the ambient light is blocked by the shielding member 202, the shape of the uneven pattern of the random pattern can be read in substantially the same shape. Note that the light source 204 may emit light including a wavelength in a non-visible region.

  In addition, the mechanism in the adapter apparatus 2 including these components is formed in accordance with optical conditions (light irradiation direction, illuminance, resolution, etc.) when a pre-registered later-described collation image is acquired. . The adapter device 2 may further include an optical system 206 provided on the optical axis of the lens unit of the camera attached to the opening 200. The optical system 206 is a lens that enables close-up shooting of an object, for example. When a camera without a macro shooting function is attached, the image of the PFP registration unit 8 can be acquired with an appropriate image quality by the optical system 206.

  As illustrated in FIG. 2B, the user attaches the adapter device 2 to the camera (not shown) of the terminal device 4 and photographs the PFP registration unit 8 of the pattern matching key 6. The image of the PFP registration unit 8 acquired in this way is obtained by photographing the shadow of the uneven pattern of the random pattern of the PFP registration unit 8 under the same optical conditions.

  The camera of the terminal device 4 is a CCD having 1.24 million effective pixels, for example. In this case, if the SXGA (1280 × 960) mode and macro shooting (maximum magnification) are about 61 mm × about 46 mm (corresponding to 0.56 times in terms of 35 mm film), the shooting area per pixel is about 48 μm × 48 μm. (About 530 dpi). With this resolution, it is possible to sufficiently capture a random pattern (paper fingerprint) having a period of μ to mm order.

Next, a pattern verification security system using such a pattern verification key 6 will be described.
FIG. 3 is a diagram showing a pattern matching security system 1 having a pattern matching key 6 and a pattern matching lock system corresponding thereto.
As shown in FIG. 3, the pattern verification security system 1 includes a terminal device 4 having an adapter device 2, a server 5 that transmits / receives data to / from the terminal device 4 via the network 3, and a pattern verification lock device 10. Having a pattern matching lock system connected via The pattern collation lock device 10 includes a control device 12 and an electric lock 16 as shown by an enlarged A in the drawing. Here, the networks 3 and 7 are LAN, WAN, etc., and may be wireless or wired.

  In the pattern verification security system 1, the terminal device 4 transmits an image of an object photographed by the camera via the adapter device 2 to the server 5. The server 5 stores a collation image composed of a random pattern on the object surface, determines whether or not the stored collation image and the image transmitted from the terminal device 4 match, and the collation image and the transmission image are determined. When it is determined that they match, either unlocking or locking is performed. The server 5 transmits data related to lock control to the control device 12, and the control device 12 controls the electric lock 16 based on this data.

The pattern matching lock device 10 is provided in, for example, a hotel, a rental apartment, a business office, a general house, and a safe door.
The electric lock 16 includes an actuator (for example, a motor, a solenoid, etc.) for unlocking and locking, and performs either unlocking or locking under the control of the control device 12. For example, when it is determined by the server 5 that the verification image matches the identification target pattern, the electric lock 16 unlocks the door under the control of the control device 12.
Hereinafter, the terminal device 4 and the server 5 will be described in detail.

FIG. 4 is a diagram illustrating a hardware configuration of the terminal device 4, the server 5, and the control device 12.
As illustrated in FIG. 4, the terminal device 4 and the like include a CPU 18, a memory 20, a communication interface (IF) 22 that transmits and receives data to and from an external computer via a network, a storage such as a hard disk drive (HDD), and the like. A device 24, an LCD display device, a keyboard / touch panel, etc., and a user interface (UI) device 26 that accepts operations from the user, and a recording that reads / writes data on an external recording medium such as an SD card, CD, or DVD device It has a medium IF28.

FIG. 5 is a diagram illustrating a functional configuration of the image transmission program 50 executed by the terminal device 4.
As illustrated in FIG. 5, the image transmission program 50 includes an image reception unit 500, a control unit 502, and a communication unit 504. With these configurations, the image transmission program 50 includes an image of an object photographed by the camera of the terminal device 4 to which the adapter device 2 (FIG. 2A) is attached, and an identifier (ID) input by the user. It transmits to the server 5. The image transmission program 50 is loaded into the memory 20 and executed by the CPU 18. Note that all or some of the functions of the image transmission program 50 may be realized by hardware provided in the terminal device 4. The same applies to the programs shown below.

  In the image transmission program 50, the image reception unit 500 receives image data (identification target pattern) acquired by the camera and outputs it to the control unit 502. The image data is, for example, image data of 32 × 32 pixels to 64 × 64 pixels, and is about 1 KB.

  The control unit 502 receives image data from the image receiving unit 500. In addition, the control unit 502 receives an ID input by the user via the UI device 26. The ID is a character string for uniquely identifying a collation image for determining the identity with the received image data. For example, the ID includes the number of the door on which the pattern matching lock device 10 is provided, and is described in advance on the door. The ID may be converted into a barcode. In this case, the ID is input to the control unit 502 by reading the barcode with the camera of the terminal device 4. The control unit 502 outputs the image data and the ID to the communication unit 504. In addition, the control unit 502 displays data input from the UI device 26, the camera, and the communication unit 504 on the display device of the UI device 26.

  The communication unit 504 outputs the image data and ID input from the control unit 502 to the server 5 via the network 3. The communication unit 504 receives data transmitted from the server 5 and outputs the data to the control unit 502.

FIG. 6 is a diagram showing a functional configuration of the pattern matching program 60 executed by the server 5.
As illustrated in FIG. 6, the pattern matching program 60 includes an image reception unit 600, a determination unit 602, a result transmission unit 604, a matching data storage unit 606, and a registration unit 608.
In the pattern matching program 60, the registration unit 608 accepts a matching image acquired by a multi-function peripheral (MFP), a PC flatbed scanner, a digital camera, or the like (not shown). The verification image is composed of a random pattern (for example, a plant fiber pattern) attached to the pattern verification key 6 for opening and closing the door provided with the pattern verification lock device 10 (FIG. 3).

  The registration unit 608 also receives an ID for uniquely identifying the collation image via the UI device 26 and stores the collation image and the ID in the collation data storage unit 606 in association with each other. The registration unit 608 may accept the expiration date and the number of validity of the collation image, and in this case, these data are also stored in the collation data storage unit 606 in association with the ID. If no ID is input, the registration unit 608 may generate and associate a unique ID.

  The collation data storage unit 606 stores the collation image, the expiration date, and the like in association with the input ID. The collation data storage unit 606 may store a plurality of collation images in association with one ID. In this case, the plurality of collation images correspond to random patterns assigned to different pattern collation keys 6, and these pattern collation keys 6 serve as so-called combination keys. When the expiration date is associated with the verification image, the verification image is valid only within the stored expiration date. Further, when the effective number is associated, the collation image is effective as long as the stored effective number is not exceeded. The collation data storage unit 606 is realized by the memory 20, the storage device 24, and the like.

The image receiving unit 600 receives the image data (identification target pattern) and ID transmitted from the terminal device 4 and outputs them to the determination unit 602.
The determination unit 602 determines whether or not the collation image with the ID stored in the collation data storage unit 606 matches the image data input from the image receiving unit 600 (that is, image data transmitted from the terminal device 4). Determine whether. When a plurality of collation images are associated with the ID, the determination unit 602 determines whether any of the plurality of collation images matches the image data to be identified. The determination unit 602 outputs the determination result of the identity determination process to the result transmission unit 604.

  More specifically, the determination unit 602 sets a plurality of verification areas shifted by one pixel for the input image data, and calculates a correlation value with the verification image in each verification area. The determination unit 602 determines whether or not a pattern having a high degree of similarity with the collation image is included based on the maximum correlation value and the value obtained by normalizing the maximum correlation value (normalized score). The identity of the stored collation image and the image data acquired from the pattern collation key 6 and transmitted is determined.

  The result transmission unit 604 transmits this determination result to the terminal device 4 via the network 3 and transmits to the control device 12 via the network 7. When the determination unit 602 determines that the collation image matches the transmitted image, the result transmission unit 604 transmits control data indicating that either unlocking or locking is performed to the control device 12. May be.

FIG. 7 is a flowchart of the pattern matching process (S10) performed by the pattern matching program 60 operating on the server 5.
As shown in FIG. 7, in step 100 (S100), the image receiving unit 600 of the pattern matching program 60 (FIG. 6) acquires the image data and ID acquired and transmitted by the terminal device 4 to which the adapter device 2 is attached. Whether or not is accepted. The pattern matching program 60 proceeds to the process of S102 when the image receiving unit 600 receives image data or the like, and returns to the process of S100 otherwise.

In step 102 (S102), the determination unit 602 refers to the collation image data corresponding to the ID stored in the collation data storage unit 606.
In step 104 (S104), the determination unit 602 determines whether the image data input from the image receiving unit 600 matches the collation image. The pattern matching program 60 proceeds to the process of S106 when it is determined that the image data to be identified matches the matching image, and proceeds to the process of S108 otherwise.

In step 106 (S106), the result transmission unit 604 outputs to the terminal device 4 and the control device 12 that the transmitted image matches the collation image. Note that the result transmission unit 604 may transmit control data for performing either unlocking or locking to the control device 12.
In step 108 (S108), the result transmission unit 604 outputs to the terminal device 4 and the control device 12 that the transmitted image and the collation image do not match. Note that the result transmission unit 604 may not transmit the determination result to the control device 12.

FIG. 8 is a diagram illustrating a functional configuration of the lock control program 70 executed by the control device 12.
As illustrated in FIG. 8, the lock control program 70 includes a determination result receiving unit 700 and an opening / closing control unit 702.
In the lock control program 70, the determination result receiving unit 700 receives the determination result transmitted from the server 5 and outputs it to the opening / closing control unit 702. When the opening / closing control unit 702 receives a determination result indicating that the identification target image matches the collation image, the opening / closing control unit 702 outputs a control signal indicating that the electric lock 16 is to be unlocked or locked. When the determination result receiving unit 700 receives control data indicating that either the unlocking or locking of the electric lock 16 is performed from the server 5, the opening / closing control unit 702 performs the electrical control based on the control data. A control signal is output to the lock 16.

FIG. 9 is a sequence diagram showing the overall operation (S20) of the pattern matching security system 1 according to this embodiment.
As shown in FIG. 9, in step 200 (S200), the administrator of this system inputs a collation image, an ID, an expiration date, and the like using the UI device 26 of the server 5. The registration unit 608 of the pattern matching program 60 (FIG. 6) of the server 5 receives the input matching image and stores it in the matching data storage unit 606 by associating the matching image with the ID. In addition, the administrator attaches, for example, a random pattern corresponding to the verification image to the PFP registration unit 8 of the pattern verification key 6. Thereafter, the pattern matching key 6 is used by a user or the like.

  In step 202 (S202), if the door provided with the pattern matching lock device 10 is locked, the user attaches the PFP registration unit 8 of the pattern matching key 6 to the adapter device 2 (FIG. 2A). Then, the camera of the terminal device 4 is taken. When the PFP registration unit 8 is photographed, the image data of the pattern matching key 6 to be identified is acquired. In addition, the user inputs an ID for identifying the door using the UI device 26.

In step 204 (S204), the acquired image data and the input ID are transmitted to the server 5 by the image transmission program 50 (FIG. 5). In the server 5, the image receiving unit 600 of the pattern matching program 60 (FIG. 6) receives the transmitted image data and the like. When image data or the like is received by the pattern matching program 60, the server 5 performs pattern matching processing (FIG. 7; S10), and determines the identity between the image data and the matching image associated with the ID. Is done.
In step 206 (S206), the determination result is transmitted from the server 5 to the control device 12 and the terminal device 4.

In step 208 (S208), in the control device 12, the determination result receiving unit 700 of the lock control program 70 (FIG. 8) receives the determination result, and the determination result is acquired from the inserted pattern matching key 6. When the pattern and the collation image of the room match, the opening / closing control unit 702 outputs a control signal to the electric lock 16 to unlock (or lock) the door of the room. . The electric lock 16 is unlocked when a control signal is received.
In step 210 (S210), in the terminal device 4, the communication unit 504 of the image transmission program 50 receives the determination result, and the control unit 502 displays the determination result on the UI device 26.

  As described above, the adapter device 2 is provided with an opening for mounting on the camera, a shielding member that blocks ambient light, and an object photographed through the opening provided inside the shielding member. A light source for irradiating light. Therefore, according to the adapter device 2, the camera-equipped mobile terminal device can be used for determining the authenticity of the random pattern on the object surface. For this reason, the determination process can be realized at a very low cost and easily compared to the case where a dedicated collator is used. The adapter device 2 can also be provided at a low cost.

  For example, it is possible to use a camera-equipped mobile phone as a device for determining the authenticity of securities, tickets, important documents, etc., determining the authenticity of expensive products, and determining a key for a safe or door. In the door key determination process, a piece of paper or a plastic card as a key is photographed and sent to the server together with the ID to perform a true / false determination process. If it is determined to be true, the door is unlocked. Is done.

In addition, according to the adapter device 2, since it is possible to shoot under stable conditions regardless of the surrounding optical conditions, the adapter device 2 can use two-dimensional bar codes (QR codes, etc.), hidden-printed codes. It can also be used when shooting steganography or the like.
Further, the adapter device 2 uses a light source (for example, an infrared LED, an ultraviolet LED, etc.) having a wavelength in the same absorption region as the color material contained in the ink or toner that absorbs only in a non-visible region such as infrared rays. Also good. As a result, it is possible to read a code or the like that is concealedly printed with such ink or toner. In the case of such a method of use, unlike the case of observing an uneven random pattern, there is no need to provide a specific provision for the direction of light irradiation on the observation target, and the light source is arranged to illuminate the target regardless of the direction. It only has to be done.

The pattern matching process may be performed in the terminal device 4.
FIG. 10 is a sequence diagram showing an overall operation (S30) of a modified example of the pattern matching security system 1. Note that, among the processes shown in FIG. 10, substantially the same processes as those shown in FIG. 9 are denoted by the same reference numerals.
As shown in FIG. 10, when image data and ID are acquired in the terminal device 4 in the processing of S202, pattern matching processing (FIG. 7; S10) is performed on the terminal device 4. Note that a pattern matching program 60 (FIG. 6) is operating on the terminal device 4, and a matching image and the like are stored in the terminal device 4 in advance.

  When the pattern matching process is performed by the terminal device 4, the determination result is transmitted from the terminal device 4 to the server 5 in step 300 (S300). Upon receiving the determination result, the server 5 transmits the determination result to the control device 12 and the terminal device 4 in the process of S206. When receiving the determination result, the control device 12 unlocks the door in the process of S208. In addition, when the terminal device 4 receives the determination result (processing completion notification) from the server 5, the terminal device 4 displays the fact on the UI device 26.

The collation image data may be stored in an external storage device such as a mini SD card that can be read by the recording medium IF 28 of the terminal device 4.
In the pattern matching program 60 operating on the terminal device 4, the matching data storage unit 606 may store image data such as a two-dimensional barcode converted based on the matching image. In this case, the corresponding pattern matching key 6 is printed with the two-dimensional barcode. When the user reads this two-dimensional code using the camera of the terminal device 4 to which the adapter device 2 is attached, the pattern matching program 60 operating on the terminal device 4 stores the photographed two-dimensional barcode. It is determined whether or not the two-dimensional barcode is the same. The stored two-dimensional barcode is generated based on a paper fiber pattern or the like, and it is difficult to forge, so the security is further improved.

Next, an adapter device 2 according to a second embodiment of the present invention will be described.
