Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a card issuing system and an entry / exit management system for managing entry / exit with respect to a predetermined area by issuing a card.
[0002]
[Prior art]
In recent years, when restricting entry / exit to a site, building, room, etc. that requires confidentiality, it is generally performed to carry a card and manage entry / exit by the card. For insiders who have such a building or room as a workplace, a card with a photo or the like is issued in advance, but for outsiders and outsiders who do not have a workplace, simply display a management number, etc. Often only cards are issued. Therefore, it is desirable to be able to easily issue a card on which photographic data visible to outsiders and outsiders is displayed.
[0003]
Conventionally, cards are generally issued to manage entry / exit to restricted areas such as premises, buildings, and rooms where confidentiality is required, and the issued cards include simple cards and IC cards. Often used. For insiders, a photo of the owner's face is often affixed to any card, but for outsiders and outsiders, a management number is assigned at the visit, unless the card is issued in advance. Cards are handed out, and visitors' business cards are put in the card case. Then, by allowing outsiders and outsiders to wear these cards and the like, entry / exit management in the restricted area is performed. In addition, as management of entry / exit in a restricted area, it is also known to manage entry / exit separately from the card or together with the card using a fingerprint or a pupil pattern.
[0004]
[Problems to be solved by the invention]
However, when managing entry / exit within a restricted area, if a card with a face photo is used for insiders, other insiders can visually confirm the identity of the insider even while acting in the area. However, with cards issued to outsiders or outsiders, it is possible to manage entry / exit by the card, and it is still possible to confirm the match between the person at the time of leaving and the person at the time of visiting In addition, for example, it is not possible to confirm even card lending and borrowing, and there is a security problem.
[0005]
Therefore, the present invention has been made in view of the above problems, and can immediately issue a card with a face photo of the person to be moved in and out so that the face photo of the card and the holder in the restricted area can be visually confirmed. It is an object of the present invention to provide a card issuing system and an entrance / exit management system that can authenticate and manage card holder entry / exit with high security.
[0006]
[Means for Solving the Problems]

In FIG. 5, first, the imaging means 52 carries the entry / exit card 22 when the control means 61 sends an imaging command to the imaging means 52 by the entry / exit permission requesting action of the holder of the entry / exit card 22. The person's face photograph is imaged (S11). Further, the holder of the entry / exit card 22 inputs, for example, ID data displayed on the entry / exit card 22 into the input means 53. The face photograph data imaged by the imaging means 52 is once stored in the imaging data acquisition means 64, and the entered / exited person data acquisition means 65 acquires the input ID data (S12).
[0036]
Subsequently, the feature extraction unit 66 creates feature extraction data obtained by extracting the feature portion based on the face photograph data captured by the imaging unit 52 (S13), while the entry / exit person data acquisition unit 65 performs the entry / exit card. The ID input by the owner 22 is sent to the host computer 13 to obtain corresponding feature extraction data from the management DB 14 (S14).
[0037]
Therefore, the matching unit 67 compares the feature extraction data of the corresponding ID acquired from the management DB 14 with the feature extraction data created by the feature extraction unit 66 (S15), determines whether or not they match, and authenticates. (S16). If they coincide with each other, the display means 68 appropriately displays permission, sends an unlocking output signal for unlocking to the driving means 54, and unlocks it (S17).
[0038]
On the other hand, if they do not match, a display for retrying the holder of the entry / exit card 22 is displayed on the display means 68 (S18). Then, the above steps S11 to S15 are repeated, and this is repeated a predetermined number of times (S19). If they still do not match, the locking is maintained and the request rejection is displayed on the display means 68 (S20).
[0039]
Thus, feature extraction data as related data of face photo data stored in the card issuance management DB 14 and feature extraction as related data of face photo data obtained by capturing the holder of the entry / exit card 22 at the time of entry / exit request By collating and authenticating data, it is possible to manage highly secure entry / exit.
