Access control system
First Claim
1. A system comprising at least one access control device providing access into a controlled area including an access authorization reader for reading a data carrier containing access authorization and identification data, and a database for storing the identification data from the data carrier in question, the access control device including a camera activatable by the reading of the data carrier or by sensors detecting forward movement of the user for taking an initial digitized image of the user of the data carrier upon an initial access into a controlled area that is permitted regardless of the digitized image, and for storing the image in the database along with the identification data for the data carrier, and at least one terminal with a display screen, to which the stored image of the user of the relevant data carrier taken by the camera of the one access control device is transferred for visual comparison with a subsequent image taken by the camera of the at least one access control device during a subsequent access into said controlled area, wherein the subsequent access includes reading of said data carrier and the subsequent image taking, and wherein the user of the particular data carrier is denied further access into the controlled area if the user images do not match, and wherein the initial access into the controlled area is permitted even when the initial image taken does not match an image of the user previously stored in the database before the initial access attempt.

Abstract
A system with at least one access control device (1) exhibiting an access authorization reader (4) for data carrier (8) containing access authorization and identification data, a database (9) and a camera (7). Once a valid access authorization is read, the identification data from the data carrier in question (8) and a digitized image of the user taken by the camera (7) are stored in the database. The stored image of the user of the particular data carrier can be transferred from the database (9) to terminals (11 to 13), in order to compare it with a image of the user previously taken and stored in the database (9). If the images of the user do not match, further access is denied for that particular data carrier (8).

A system comprising at least one access control device providing access into a controlled area including an access authorization reader for reading a data carrier containing access authorization and identification data, and a database for storing the identification data from the data carrier in question, the access control device including a camera activatable by the reading of the data carrier or by sensors detecting forward movement of the user for taking an initial digitized image of the user of the data carrier upon an initial access into a controlled area that is permitted regardless of the digitized image, and for storing the image in the database along with the identification data for the data carrier, and at least one terminal with a display screen, to which the stored image of the user of the relevant data carrier taken by the camera of the one access control device is transferred for visual comparison with a subsequent image taken by the camera of the at least one access control device during a subsequent access into said controlled area, wherein the subsequent access includes reading of said data carrier and the subsequent image taking, and wherein the user of the particular data carrier is denied further access into the controlled area if the user images do not match, and wherein the initial access into the controlled area is permitted even when the initial image taken does not match an image of the user previously stored in the database before the initial access attempt.
- 10. A system comprising at least one access control device providing access into a controlled area including an access authorization reader for reading a data carrier containing access authorization and identification data, and a database for storing the identification data from the data carrier in question, the access control device including a camera activatable by the reading of the data carrier or by sensors detecting forward movement of the user for taking an initial digitized image of the user of the data carrier upon an access, and for storing the image in the database along with the identification data for the data carrier, at least one terminal with a display screen, to which the stored image of the user of the relevant data carrier taken by the camera of the one access control device is transferred for visual comparison with a subsequent image taken by the camera of the at least one access control device during a subsequent access into said controlled area, wherein the subsequent access includes reading of said data carrier, and a selection program for selecting certain data carriers for the transmission of images from the database to the terminal for visual comparison purposes, wherein the data carrier is free from an image of the user, and wherein the user of the particular data carrier is denied further access into the controlled area if the user images do not match, wherein the initial access is permitted even when the initial image taken does not match an image of the user previously stored in the database before the initial access attempt.

13. A method of providing access to a controlled area comprising the steps of:
- providing a system including at least two access control devices, each said access control device including an access authorization reader, a terminal with a display screen and a camera for taking a digitized image, said system including a database receiving and sending information to said at least two access control devices;
providing a data carrier for each individual user, the data carrier containing access authorization and identification data for enabling access to the controlled area;
determining attempted entry of the controlled area at one of the at least two access control devices by detecting the data carrier carried by an individual user with the respective access authorization reader;
in response to an initial detection of the data carrier, taking an initial digitized image of the user with the data carrier at the one access control device, and permitting an initial access into the controlled area even when the initial image taken does not match an image of the user previously stored in the database before the initial access attempt;
providing the initial image of the user and the corresponding data carrier authorization and identification data to the database for storage in the database;
visually comparing a subsequent image taken at the access control device with the initial image stored in the database for the user;
determining for the user with the data carrier whether the initial image and the subsequent image match; and
detecting a subsequent entering of a selected one of the at least two access control devices by reading the data carrier carried by the individual user with the corresponding access authorization reader and permitting entry only if the previous visual comparison of the images match. - View Dependent Claims (14, 15, 16, 17, 18)
