Abstract

A system for providing stand-off biometric verification of a driver of a vehicle at a control gate while the vehicle is moving, including an RFID vehicle tag reader, an RFID personal tag reader and a facial detection and recognition (verification) system. The RFID vehicle tag reader scans and reads data from an RFID vehicle tag of the vehicle that is trying to pass through the gate. The RFID personal tag reader reads data from an RFID personal tag carried by personnel who are driving in the vehicle. The facial detection and verification system scans and reads facial images for the driver. All the data and facial images detected by the reader are sent to a computer for further processing (final face verification).

Claims

1. A method for providing dynamic security verification, comprising:

storing data regarding information and a face print of a person in a database, wherein the face print is represented by numerical codes of a face image of the person;

recording data regarding the information of the person in a database;

reading an RFID device and relating a read RFID number to the information stored in the database;

retrieving a face print corresponding to the data read from the RFID from the database;

scanning a face of the person with low near infrared (IR) light and high near-IR light to obtain a first facial image and a second facial image, respectively;

subtracting the second facial image from the first facial image to obtain a skin image of the person,

performing a multi-band extraction on the first and second facial images to obtain a third facial image,

combining the skin image and third facial image to obtain a final facial image; and

comparing the final facial image with the retrieved face print.

2. The method of claim 1, wherein the data regarding the information of the person comprises personal information and vehicle information of the person.

3. The method of claim 1, wherein the face of the person is scanned dynamically and automatically when the person passes by a reading point.

4. A method for dynamically verifying a vehicle and a person riding in the vehicle at a control gate, wherein the vehicle carries an RFID vehicle tag and the person carries an RFID personnel tag, the method comprising:

recording information of the person and the vehicle in the RFID personnel tag and the RFID vehicle tag, respectively;

reading vehicle data from the RFID vehicle tag when the vehicle passes through a sensing point and sending the vehicle data to a computer for processing;

reading personal data from the RFID personnel tag and sending the personal data to the computer for processing;

scanning a face of the person to obtain a facial image;

retrieving data regarding the vehicle and person from a database and comparing the retrieved data with the read vehicle and person data;

retrieving a stored face template from the database corresponding to the read vehicle and person data; and

comparing the facial image with the retrieved face template to verify identity.

5. The method of claim 4, further comprising a step of indicating if the vehicle and the person are authorized entry when all of the data read from the RFID vehicle tag and RFID personnel tag and the facial image of the person match with the data and the face template stored in the database.

6. The method of claim 5, wherein when either one of the data read from the RFID vehicle and personnel tags and the facial image of the personnel fail to match with data and the face templates stored in the database, the vehicle is stopped for further questioning of the person.

7. The method of claim 4, wherein the scanning a face of the personnel further comprises:

scanning the face of the person by a low near-IR light and a high near-IR light to obtain a first and a second facial image, respectively;

subtracting the second facial image from the first facial image to obtain a skin image;

performing a multi-band extraction on the first and the second facial image to obtain a third facial image; and

combining the skin image and the third facial image to obtain the final facial image.

8. A system for dynamic stand-off verification in which an RFID tag on which personal information of an individual is stored, comprising:

a database for storing data regarding information and facial templates of a plurality of individuals;

an RFID tag reader for reading data from the RFID tag;

a facial recognition reader for scanning a face of at least one of the plurality of individuals and obtaining scanned facial images for at least one individual; and

a computer for processing the data read by the RFID tag reader and the facial images obtained by the facial recognition reader,

wherein the data read by the RFID tag and the scanned facial images are sent to the computer, and the computer, according to received data, retrieves data regarding information of the vehicle and the at least one individual from the database and determines if the received data matches stored data; and

wherein the computer processes the facial images from the facial recognition reader to obtain a final facial image, retrieves stored facial templates from the database and compares the processed facial images with the stored facial templates.

9. The system of claim 8, further comprising a sensor which is activated when the individual passes a sensing line, and the activation of the sensor further activates a sequence for the RFID tag reader and the facial recognition reader.

10. The system of claim 8, wherein the personal information stored in the RFID tag includes information regarding the individual and a vehicle the individual is driving.

11. The system of claim 10, wherein the RFID tag comprises an RFID vehicle tag on which the information regarding the vehicle is stored and an RFID personnel tag on which the information regarding the individual is stored.

12. The system of claim 11, wherein the RFID tag reader includes an RFID vehicle tag reader and an RFID personnel tag reader.

13. The system of claim 8, further comprising an indication device for indicating if the data read from the RFID tag and the facial image read by the facial recognition data match with the data and the facial templates stored in the database.

14. The system of claim 8, wherein the RFID tag and the facial recognition reader are located in front of a control gate of a facility.

15. The system of claim 8, wherein the RFID tag and the facial recognition reader are located in front of a door of a building.

16. The system of claim 8, wherein the facial recognition reader comprises:

a near-IR illuminator for generating near-IR light;

an illumination adjustment module for adjusting the near-IR light based on environmental lighting conditions;

a camera for taking facial images of the individual, and

a computer for processing the facial images to obtain a face image.

17. The system of claim 8, wherein the data stored in the database comprises personnel and vehicle data.

18. The system of claim 17, wherein the data read from the RFID tag is related to the stored data in the database for the personnel and vehicle data.
