By setting the traffic determination condition, it is possible to easily and reliably prevent the held IC card from being illegally used by another person.

Hereinafter, a case where the embodiment of the present invention is applied to a non-contact IC card gate device with fingerprint authentication will be described as an example with reference to FIGS.
Embodiment 1 FIG.
FIG. 1 is a block diagram showing a functional configuration of a contactless IC card gate device with fingerprint authentication according to Embodiment 1 of the present invention.

  Further, on the output side of the card reading means 3, an ID number acquisition means 7 for acquiring an ID number for identifying who the access card is from the card, and a card recorded in advance by a card issuing device (not shown) or the like In-card fingerprint data reading means 8 is provided for acquiring fingerprint data of the individual. The processing in the above means is substantially processed in parallel in the gate device 1, and the IC card input waiting process and the fingerprint reading process operate simultaneously, and both input operations are accepted.

  Here, in order to identify who is the basic function of the gate device 1, as an ID number, the ID number taken from the non-contact IC card 2, that is, on the output side of the ID number acquisition means 7 Based on the obtained ID number, the fingerprint (numerical value) data obtained from the fingerprint data reading means 6 and a plurality of registered fingerprint (numerical value) data registered in advance in the internal registered fingerprint data 9, which ID is read There are both ID numbers obtained on the output side of the fingerprint data search ID identifying means 10 for sequentially searching whether the number is a finger of a person.

  These ID numbers are checked by the valid ID number confirmation means 12 for the contents of valid conditions for each ID (expiration date, passable place, passable time zone, etc.) preset in the ID information data 11, and In the ID number authentication condition confirmation means 13, if the authentication is independent according to the pass authentication conditions (single authentication, card + fingerprint combined authentication, card + in-card fingerprint authentication) set for each ID, nothing is done. The final determination result (OK / NG) is notified to the passage control history means 14. In the case of the card + fingerprint composite authentication, the specified ID fingerprint data in the fingerprint data and the passerby's fingerprint data obtained from the fingerprint data reading means 6 are compared and collated by the fingerprint collation judging means 15, and the result is OK. If there is, the final determination result is also notified to the traffic control history means 14 through the ID number authentication condition confirmation means 13 as OK. Further, in the case of card + in-card fingerprint authentication, the ID verification condition confirmation unit is compared by collating the personal fingerprint data read from the accessed IC card with the fingerprint collation determination unit 15 instead of the built-in fingerprint data. 13 and notifies the traffic control history means 14.

  The card reading means 3, the ID number acquisition means 7 and the in-card fingerprint data reading means 8 substantially constitute an IC card reading means, and include a fingerprint sensor 5, a fingerprint data reading means 6, a fingerprint data search ID identifying means 10 and The fingerprint collation determination means 15 substantially constitutes a fingerprint authentication means, and the ID number confirmation means 12, the ID number authentication condition confirmation means 13 and the traffic control history means 14 substantially constitute a traffic control means.

  With the above configuration, both the IC card and the fingerprint can be freely selected as the authentication method at the time of passing, and in order to further improve the identity verification accuracy, the card information and the result of the fingerprint information can be combined to be determined. Unauthorized use can be easily and reliably prevented. In addition, it is possible to select the case where the fingerprint data to be identified is stored in the gate device or the case where it is recorded in the personal IC card, and there is an effect that the restriction on the memory in the gate device and the restriction on the number of registered persons are eliminated.

FIG. 2 is a block diagram showing the configuration of the contactless IC card gate device with fingerprint authentication according to Embodiment 1 of the present invention.
2, the gate device 1 includes a CPU 21 that executes various controls and processes. The CPU 21 reads the information on the contactless IC card 2 (FIG. 1), and the antenna 22 reads the information. A card R / W (Reader / Writer) unit 23 for reading and writing information is connected in series. The CPU 21 is connected in series with a fingerprint sensor 24 for reading personal fingerprint information and an image processing unit 25 for converting image information captured by the fingerprint sensor 24 into numerical data.

  Further, the CPU 21 has a liquid crystal panel 26 for displaying operation guidance and the like, a memory 27 for storing fingerprint data, ID information data and the like in FIG. 1, and an external upper management PC (personal computer) 30 for recording and displaying a traffic history. A communication IF 28 that performs communication and an I / O unit 29 that controls the electric lock 31 of the passage target door outside are also connected.

The appearance of the gate device 1 is a panel terminal shape as shown in FIG. 3 so that it can be installed on the wall of the passage target door, FIG. 3 (a) is its front view, and FIG. 3 (b) is its side. It is sectional drawing.
As shown in FIG. 3A, the terminal includes a liquid crystal panel 41 corresponding to the liquid crystal panel 26 of FIG. 2 for displaying operation guidance and the like, a fingerprint finger placement unit 42 for capturing fingerprint data, and a non-contact IC card 43. The IC card insertion slot 44 has a built-in antenna part. The shape of the IC card insertion slot 44 viewed from the side is a fingerprint in the non-contact IC card 43 as shown in FIG. The non-contact IC card 43 is a holder so that the distance between the card and the antenna can be kept constant so that the data information can be read stably, and the IC card holding holder 45 is an example.

FIG. 4 is a diagram showing the structure of fingerprint data + ID information database (hereinafter simply referred to as fingerprint + ID database) in the IC card gate device according to the first embodiment of the present invention.
Here, a case of a fingerprint + ID database in which the information of registered fingerprint data (× n) 9 and ID information data 11 shown in FIG.
In the fingerprint + ID database, using the ID number as a key, a traffic validity condition (AC) for designating a card number (CARD) unique to the non-contact IC card 2, an expiration date, a traveling time zone, etc. corresponding to each personal ID, A pass authentication condition (TYPE) that specifies an authentication pattern of single authentication or a combination of a card and a fingerprint, and ID data of individual fingerprint data (FingerD) is recorded, and a plurality of fingerprint data is recorded (× n), A fingerprint + ID database is constructed.

Next, the operation will be described with reference to FIG.
First, input from a non-contact IC card will be described. Access the non-contact IC card 2 (insert a card into the IC card insertion slot 44) (step S1), read the card number of the non-contact IC card 2 inserted by the card reading means 3 (step S2), ID The number acquisition means 7 searches for a record that matches the card number (CARD) in the fingerprint + ID database (step S3). If there is, the ID number (IDin) of that record is extracted, otherwise it is NG.

  Similarly, it is monitored whether or not the passer's finger is placed on the fingerprint finger placing unit 42 (FIG. 3) (step S4), and when it is placed, the fingerprint data from the fingerprint sensor 5 is read by the fingerprint data reading means 6. (Step S5) Using the result (Fin) of the image processing performed by the fingerprint data search ID identifying means 10, a search is made as to whether the fingerprint + fingerprint data (FingerD) in the ID database matches (Step S6). If the ID number of the record is extracted, it is NG if not.

  Next, the ID number (IDin) designated by the IC card or the fingerprint input is referred to by the valid ID number confirmation means 12, and the pass / valid condition (AC) of the ID number in the fingerprint + ID database is set to the current date / time / location / time. A check is performed under conditions such as a belt, and it is determined whether or not traffic is possible (step S7). If it is valid, the authentication condition confirmation means 13 for each ID checks the authentication condition (TYPE) in the fingerprint + ID database and selects the subsequent authentication pattern, that is, designates the subsequent authentication method (step) S8).

  If the authentication pattern selected in step S8 is single, the determination is made based on the determination result based on the card and the fingerprint so far, and the traffic OK and the traffic control history means 14 are notified. On the other hand, if the authentication pattern selected in step S8 is card + registered fingerprint composite authentication (composite 1), the fingerprint + ID database in the fingerprint + ID database is extracted with the input ID number (IDin) (step S9), the fingerprint data (Fdb) and the fingerprint data (Fin) input from the fingerprint sensor 5 are compared and collated by the fingerprint collation judging means 15 (step S10), and if the notification to the traffic control history means 14 matches, If it does not match, it is determined as NG.

  If the authentication pattern selected in step S8 is card + in-card fingerprint authentication (composite 2), the fingerprint data (FCard) in the card is read from the held IC card by the in-card fingerprint data reading means 8. Reading (step S11), the fingerprint data (FCard) and the fingerprint data (Fin) input from the fingerprint sensor 5 are compared and verified by the fingerprint verification determination means 15 (step S12), and a notification to the traffic control history means 14 is sent. If they match, it is OK, and if they do not match, it is NG.

  The determination result (OK / NG) from the passage control history means 14 determined at each stage is displayed on the liquid crystal panel 26 (= liquid crystal panel 41) (step S13), and in the case of OK, passage is permitted. Then, the electric lock 31 of the predetermined door is released (step S14), the upper management PC 30 is notified of the passage result (passage OK or NG), and is left as a history (step S15).

  As described above, according to the first embodiment, when operating a traffic management system using an IC card, it is necessary to always hold the card, and if it is forgotten, it cannot pass. However, by registering the fingerprint in advance, even if there is no card, it is possible to pass only with the fingerprint, and convenient operation is possible, and the convenience is excellent. In addition, by setting the traffic judgment conditions, it is possible to make judgments based on the combined result of the IC card information and the fingerprint collation result in order to prevent others from using the held IC card for any unauthorized use. It can be easily and reliably prevented.

  In the case of fingerprint verification, the fingerprint data to be determined must be set in the gate device in advance, and a memory source for storage is also required, but it is stored in an IC card that holds personal fingerprint data. , It can be compared with the data read at the time of access, the operation time for registering personal data can be saved, the memory size in the gate device can be reduced, the cost is low, and the registration depends on the memory capacity No restrictions on the number of people.
