Description

  The present invention relates to a fingerprint collation apparatus, and more particularly to a fingerprint collation apparatus having a function of acquiring a fingertip of an authenticated person at the same time as fingerprint collation.

  In recent years, immigration in each country has become stricter. Recently, a concept for strict screening of immigrants using biometric information has been proposed. This concept is to obtain a fingerprint image and a face image of an immigration person at the time of immigration, and determine whether the immigration person is included in the list of people to watch out for using biometric authentication. It is also proposed to embed an IC chip in the passport and record biometric information such as fingerprint images and face images along with the personal information of the immigrants and strictly check whether the passport holder is the person himself / herself. . Furthermore, it has been proposed to store not only the fingerprint image of the entrant but also the DNA when entering the country. According to this, when an immigrant is involved in a crime in the country, it is considered that a rapid criminal investigation can be developed by using DNA.

  Conventionally, various techniques have been proposed to improve the performance of a fingerprint collation apparatus.

  For example, there is a technique that can reduce an error in fingerprint input when dirt or the like adheres to the fingertip of the person to be authenticated and fingerprint input cannot be performed accurately. This technique dries dirt and the like attached to the fingertip of the person to be authenticated, and forms an oil film only on the ridges of the fingerprint. As a result, the adhesion between the ridge and the fingerprint reading surface of the fingerprint sensor is greatly improved, and false recognition is reduced (Patent Document 1).

In addition, for example, there is a technique that has a purification means for keeping the fingerprint reading surface clean and can prevent erroneous recognition due to contamination of the fingerprint reading surface. In this technique, a transparent film is disposed on a fingerprint reading surface of a fingerprint sensor, and the transparent film is wound up by a winding mechanism unit for a predetermined length each time a fingerprint is read. As a result, a new transparent film is always arranged on the fingerprint reading surface, so that erroneous recognition due to dirt or the like is reduced (Patent Document 2).

Conventionally, DNA is obtained by collecting the hair of a person to be authenticated, skin debris, etc., and performing DNA extraction work. In particular, when collecting fingertip dirt as skin debris, the person to be authenticated presses the fingertip against a film or the like that is in contact with the finger of the person to be authenticated, and the remaining fingertip dirt due to the viscosity of the film. DNA is extracted from etc. As described above, in extracting the DNA of the person to be authenticated, the work of collecting skin fragments and the like has been performed independently.
Therefore, if it is possible to acquire the fingertip of the person to be authenticated in fingerprint collation in which the person to be contacted touches the fingerprint reading surface, it is not necessary to independently perform the work of collecting skin debris, It is thought that work efficiency improves.

  The purpose of the present invention is to realize a quick criminal investigation using a fingerprint image or DNA of a person to be authenticated when the person to be authenticated is involved in a crime in the country. It is an object of the present invention to provide a fingerprint collation apparatus that can acquire dust and the like simultaneously with fingerprint collation.

The fingerprint collation apparatus is characterized in that the position information where the finger is placed by the person to be authenticated is a symbol indicating the position on the film described on the film . According to this, the reference information indicating the position on the film can be referred to and the specific information indicating the person to be authenticated can be associated with the position where the person to be authenticated has placed his finger.

The present invention is the fingerprint collation apparatus characterized in that the area for recording the specific information and the positional information on the film where the finger is placed by the person to be authenticated is a recording medium . According to this, the person to be authenticated and the information that can associate the person to be authenticated can be recorded on the recording medium.

The fingerprint collation apparatus further includes a writing unit that writes on the film information in which specific information indicating the person to be authenticated is associated with a position where a finger is placed by the person to be authenticated. It is. According to this, the information which matches a to-be-authenticated person and the position which the to-be-authenticated person put the finger | toe can be written in the said film .

In the present invention, on the fingerprint reading surface of the fingerprint sensor, there is viscosity on the surface that contacts the finger of the person to be authenticated, and the information that can associate the person to be authenticated and the position where the person to be authenticated puts the finger By arranging a film having a transparent elastic film having a recording medium capable of recording the information, it is possible to obtain the person to be authenticated and the fingertip of the person to be authenticated in association with each other in fingerprint verification.

  FIG. 3 is a configuration diagram of the pressure measuring device 12 described above. The pressure measuring device 12 includes a pressure sensor 16, a storage unit 17, a calculation unit 18, and a control unit 19. The pressure sensor 16 measures the pressure applied to the fingerprint reading surface of the fingerprint sensor 3 and stores the measured value in the storage unit 17. The calculation unit 18 performs various calculations such as differential processing of pressure values stored in the storage unit 17. Note that the control unit 19 controls these operations.

  Processing of the fingerprint collation device in the embodiment of the present invention will be described with reference to the drawings.

  The process for the passport reader 9 will be described with reference to FIG.

  In step S001, the passport reader 9 determines whether or not the passport has been read by the person to be authenticated. If this determination is affirmative, the passport has been read, and the process proceeds to step S002. On the other hand, if this determination is negative, the processing returns to step S001.

  In step S002, the passport reader 9 stores the passport information of the person to be authenticated in the passport information storage unit 10. Here, the passport information means a passport number, name, date of birth, nationality, issuing country, expiration date, and the like. In step S002, the reason for saving the passport information of the person to be authenticated is that the passport information is written on the magnetic stripe 25 of the transparent film 20 and the position where the finger is placed by the person to be authenticated, as will be described later. This is for associating. The process proceeds to step S003.

  When the saving of the passport information of the person to be authenticated is completed in the passport information storage unit 10, the passport reader 9 notifies the sequence control unit 2 of the completion of saving in step S003. The process ends.

  The process for the sequence control unit 2 will be described with reference to FIG.

  In step S004, the sequence control unit 2 determines whether or not a passport information storage completion notification has been received from the passport reader 9. If this determination is affirmative, there is a storage completion notification, and the process proceeds to step S005. On the other hand, if this determination is negative, the processing returns to step S004.

  Processing for the pressure measuring device 12 will be described with reference to FIG.

The pressure measuring device 12 measures the pressure applied to the fingerprint reading surface. When this value is equal to or greater than a certain value and stable, it is determined that the finger is properly placed by the person to be authenticated. This is because if the finger is not placed on the fingerprint reading surface in a state where a certain force is applied to the fingertip, the fingertip of the person to be authenticated as the collection information does not remain on the transparent film 20. In step S006, the pressure sensor 16 measures the pressure P _t in accordance with the fingerprint reading face. Here, t represents time. The process proceeds to step S007.

In step S007, the control unit 19 stores the pressure P _t of the pressure sensor 16 measured in step S006 in the storage unit 17. The process proceeds to step S008.

  In step S008, the calculation unit 18 determines whether or not the measured pressure is a certain value or more. This is because, if the pressure applied to the fingerprint reading surface is not equal to or higher than a certain value, the finger 20 of the person to be authenticated is not left on the film 20. If this determination is affirmative, the pressure applied to the fingerprint reading surface is equal to or greater than a certain value, and the process moves to step S009. On the other hand, if this determination is negative, the processing returns to step S006.

In step S009, the arithmetic unit 18 at time t, it calculates a difference value of the pressure P _t and P _t-1 of the pressure sensor is measured continuously between t-1. The process proceeds to step S010.

  In step S010, the calculation unit 18 determines whether or not the difference value calculated in step S009 is equal to or less than a predetermined value. When the finger is stably placed on the fingerprint reading surface with a force equal to or higher than a predetermined pressure by the person to be authenticated, the difference value becomes close to zero. At this time, the fingerprint sensor acquires a fingerprint image. If this determination is affirmative, the process proceeds to step S011 because the finger is stably placed on the fingerprint reading surface with a force equal to or greater than a predetermined pressure by the person to be authenticated. On the other hand, if this determination is negative, the processing returns to step S006.

  In step S011, the control unit 19 notifies the sequence control unit 2 of completion of finger placement. The process ends.

  In step S014, the fingerprint sensor 3 determines whether or not a start notification has been received from the sequence control unit 2. If this determination is affirmative, there is an activation notification, and the process proceeds to step S015. On the other hand, if this determination is negative, the processing returns to step S014.

  In step S015, the fingerprint sensor 3 acquires a fingerprint image of the person to be authenticated. The process proceeds to step S016.

  In step S016, the fingerprint sensor 3 stores the fingerprint image in the fingerprint image storage buffer 4. The processing moves to step S017.

  In step S017, the fingerprint sensor 3 notifies the sequence control unit 2 that the fingerprint image storage has been completed. The process ends.

  The process for the sequence control unit 2 will be described with reference to FIG.

  In step S018, the sequence control unit 2 determines whether a fingerprint image storage completion notification has been received from the fingerprint sensor 3. If this determination is affirmative, there is a notification of completion, and the process proceeds to step S019. On the other hand, if this determination is negative, the processing returns to step S018.

  In step S019, the sequence control unit 2 activates the fingerprint search device 5. The process ends.

  Processing for the fingerprint search device 5 will be described with reference to FIG.

  In step S020, the fingerprint search device 5 determines whether an activation notification is received from the sequence control unit 2. If this determination is affirmative, there is an activation notification, and the process proceeds to step S021. On the other hand, if this determination is negative, the processing returns to step S020.

  In step S021, the fingerprint search device 5 acquires the fingerprint image of the person to be authenticated stored in the fingerprint image storage buffer 4 in step S016. The processing moves to step S022.

  In step S022, the fingerprint search device 5 determines whether or not the fingerprint image of the person to be authenticated matches each fingerprint image stored in advance in the sensitive person fingerprint image DB6. If there is a matching image, the person to be authenticated is determined to be a person requiring attention, and the process proceeds to step S024. On the other hand, if there is no matching image, the process proceeds to step S023.

  In step S023, the fingerprint search device 5 notifies the sequence control unit 2 that the fingerprint collation has been completed (there is no matching fingerprint image). The process ends.

  In step S024, the fingerprint search device 5 notifies the sequence control unit 2 that the fingerprint collation has been completed (there is a matching fingerprint image). The process ends.

  Processing for the sequence control unit 2 will be described with reference to FIG.

  In step S025, the sequence control unit 2 determines whether or not there is a collation completion notification (there is no matching fingerprint image) from the fingerprint search device 5. If this determination is affirmative, there is a notification of completion, and the process proceeds to step S026. On the other hand, if this determination is negative, the processing returns to step S025.

  In step S026, the sequence control unit 2 activates the winding mechanism unit 7 to wind up the transparent film 20 by a predetermined length. The process ends.

  The process for the winding mechanism unit 7 will be described with reference to FIG.

  In step S027, the winding mechanism unit 7 determines whether or not a start notification is received from the sequence control unit 2. If this determination is affirmative, there is an activation notification, and the process proceeds to step S028. On the other hand, if this determination is negative, the processing returns to step S027.

  In step S028, the winding mechanism unit 7 starts winding the transparent film 20. The processing moves to step S029.

  In step S029, the winding mechanism unit 7 notifies the sequence control unit 2 that the winding start has been completed. In response to the notification from the winding mechanism unit 7, the sequence control unit 2 activates the magnetic stripe writing unit 8. As a result, simultaneously with the winding of the transparent film 20, it becomes possible to start the magnetic stripe writing unit 8 and write the passport information to the magnetic stripe 25. The processing for the magnetic stripe writing unit 8 will be described later. The process proceeds to step S030.

  In step S030, the winding mechanism unit 7 winds up the transparent film 20. In this embodiment, each time the fingerprint sensor 3 reads the fingerprint image of the person to be authenticated, the winding mechanism unit 7 winds the transparent film 20 by a predetermined length. The predetermined length is the length of one side of the area where the finger assigned to each person to be authenticated is placed. As shown in FIG. 20 (b), by dividing the area allocated to each person to be authenticated and winding up the length of this area, the finger marks for one person to be authenticated remain in each area. To do. As a result, the transparent film 20 is supplied from the supply roll 27 and is taken up by the take-up roll 28. The process proceeds to step S031. Here, a technique for winding the transparent film 20 by a predetermined length will be described. As shown in FIG. 20 (a), when the winding roll winds up the transparent film 20, the winding radius, which is the radius of the cross-section circle including the winding roll 28 and the transparent film 20, increases. Go. That is, if the winding mechanism unit 7 is always controlled to move by a certain angle, the length of winding the transparent film 20 increases as the winding radius increases, and a finger is placed on each person to be authenticated. It becomes impossible to allocate the area evenly. Therefore, as shown in FIG.20 (b), a reading mark 29 is printed on the boundary of the area allocated to each person to be authenticated on the transparent film 20, and the winding mechanism unit 7 reads this reading mark 29 each time. Stop winding. As a result, it is possible to realize winding up of the transparent film 20 by a predetermined length.

If this determination is affirmative, the reading mark 29 has been read, and the process moves to step S032. On the other hand, if this determination is negative, the processing returns to step S030.

  In step S032, the winding mechanism unit 7 finishes winding. The processing moves to step S033.

  In step S033, the winding mechanism unit 7 notifies the sequence control unit 2 that the winding has been completed. The process ends.

  The process for the sequence control unit 2 will be described with reference to FIG.

  In step S034, the sequence control unit 2 determines whether or not a winding start completion notification is received from the winding mechanism unit 7. If this determination is affirmative, there is a winding start completion notification, and the process proceeds to step S035. On the other hand, if this determination is negative, the processing returns to step S034.

  In step S035, the sequence control unit 2 activates the magnetic stripe writing unit 8 to write the passport information to the magnetic stripe 25. The process ends.

  The processing for the magnetic stripe writing unit 8 will be described with reference to FIG.

  In step S036, the magnetic stripe writing unit 8 determines whether or not the activation notification is received from the sequence control unit 2. If this determination is affirmative, there is an activation notification, and the process proceeds to step S037. On the other hand, if this determination is negative, the processing returns to step S036.

  In step S037, the magnetic stripe writing unit 8 acquires the passport information of the authentication subject stored in the passport information storage unit 10 in step S002. The processing moves to step S038.

  In step S038, the magnetic stripe writing unit 8 writes the passport information of the person to be authenticated into the magnetic stripe 25 on the transparent film 20 that is wound by the winding mechanism unit 7. As a result, the person to be authenticated and the position where the person to be authenticated placed the finger can be associated with each other, and further, the person to be authenticated and the fingertip of the person to be authenticated remaining on the transparent film can be associated with each other. . The process proceeds to step S039.

If this determination is affirmative, there is a notification of completion of fingerprint image acquisition, and the process moves to step S204. On the other hand, if this determination is negative, the processing returns to step S203.

  In step S204, the sequence control unit 2 acquires the time from the timer 13. As a result, the sequence control unit 2 can acquire the date, time, minute, and second when the finger is placed on the fingerprint reading surface by the person to be authenticated. The process proceeds to step S205.

  In step S205, the sequence control unit 2 notifies the magnetic stripe writing unit 8 of the time acquired in step S204. The process ends.

If this determination is affirmative, the time information has been notified, and the process moves to step S207. On the other hand, if this determination is negative, the processing returns to step S206.

  In step S207, the magnetic stripe writing unit 8 writes time information to the magnetic stripe 25 on the transparent film. As a result, the magnetic stripe 25 has the date, time, minute, and second when the finger is placed on the fingerprint reading surface by the person to be authenticated. The process ends.

  In the first embodiment, the magnetic stripe writing unit 8 writes information that can identify the user to be authenticated to the magnetic stripe 25 on the transparent film on which the user has placed a finger, so that the user to be authenticated and the user to be authenticated can be identified. Although it has been described that the association with the position where the finger is placed has been described, other configurations may be considered.

  The transparent film used in Example 4 does not have a magnetic stripe like the transparent film 20 used in Example 1, and as shown in FIG. 20 (c), on the film, for example, P1, P2,. In addition, a winding symbol 30 that can specify an area where the person to be authenticated places a finger is printed. The winding mechanism unit 7 winds up the transparent film by a predetermined length every time the fingerprint of the person to be authenticated is read. For this reason, by referring to the winding symbol 30 that can specify the region, it can be understood how many persons to be authenticated have wound the winding mechanism section 7. Therefore, if the order of the person to be authenticated using the fingerprint collation apparatus can be grasped in advance, the person to be authenticated and the transparent film on which the finger is placed by the person to be authenticated can be associated by referring to the symbol. it can.

However, for example, if there is a trend to have biometric information in a license in the future, the license center will Implementation is also possible. In the above embodiment, the whole fingerprint collation apparatus has been described. However, the fingerprint sensor may be provided with a function for acquiring the fingertip of the person to be authenticated at the same time as reading the fingerprint. In this case, it is conceivable to use a fingerprint sensor having the function connected to a PC.
