Abstract

A biometric identification device comprising a computer unit (3) arranged to execute an identification program and a registration program for storing in memory both biometric characteristics and also identifiers of people to be identified subsequently. The device comprises means for exchanging data with a distinct computer terminal (100) provided with a screen, and the registration program comprises a web server programmed to co-operate with a web browser of the terminal to set up a bidirectional communication channel and to send in real time to the web browser, via the communication channel, information about capture progress in order to enable the information to be displayed on the terminal in the form of a capture web page.

First claim

The invention claimed is:

1. An identification device, comprising:
a capture unit for capturing biometric characteristics;
a computer unit connected to the capture unit in order to control it, the computer unit being arranged to execute an identification program and a registration program for storing in memory both biometric characteristics and also identifiers of at least one person who is to be identified subsequently; and
means for exchanging data with a distinct computer terminal provided with a screen and an input interface,
wherein the registration program comprises a web server programmed to co-operate with a web browser of the terminal to establish a bidirectional communication channel, and
wherein the registration program is arranged to act in real time by means of the capture unit to determine information about the progress of capture from images of an image stream captured and sent by the capture unit and to send in real time to the web browser, via the communication channel, the information about the progress of capture so that it can be displayed on the terminal in the form of a capture web page.

2. A device according to claim 1 , wherein the bidirectional communication channel is a full duplex channel.

3. A device according to claim 2 , wherein the bidirectional communication channel uses a protocol in compliance with the RFC 6455 standard.

4. A device according to claim 1 , wherein the registration program is arranged to send to the web browser an identification page for identifying a registration supervisor, which page includes at least one field that is to be completed, and to make continuation of registration dependent on successful verification of the content of the completed field.

5. A device according to claim 1 , wherein the registration program is arranged to send to the web browser an identification page for a candidate for registration including at least one field that is to be completed with an identifier of the candidate for registration and to associate that identifier with the captured biometric characteristics.

6. A device according to claim 1 , wherein the information about capture progress includes an image produced by the capture unit.

7. A device according to claim 1 , wherein the information about capture progress includes information about repositioning the candidate for registration relative to the capture unit.

8. A device according to claim 1 , wherein the information about capture progress includes information about the quality of the capture.

9. A device according to claim 1 , wherein the registration program is arranged to evaluate the quality of the captured image and to restart capture if the quality of the image is below a threshold.

10. A device according to claim 1 , wherein the registration program has a plurality of parameter settings for sending information about capture progress as a function of the type of computer terminal, of the type of web browser or of a rate at which data is to be exchanged with the web browser.

11. An access authorization device including a locking device for locking access and an identification device in accordance with any preceding claim and connected to the locking device in order to control it.
