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 a pre-verification system and a post-verification systems. The pre-verification system is installed before an entrance of a facility and comprises 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 an ID from an RFID vehicle tag of the vehicle that is trying to pass through the gate. The RFID personal tag reader reads an ID 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. The post-verification system is installed on at least one of an entrance and an exit for post-verification to ensure that the vehicle that enters the entrance or leaves from the exit is the one that has been verified/denied at the control gate. In one embodiment, the post-verification system comprises an RFID personal tag reader and an RFID vehicle tag reader. In another embodiment, the post-verification system also comprises a facial detection and recognition system.

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;

at a first checkpoint, reading an RFID device and relating a read RFID number to the information stored in the database,

retrieving a face print corresponding to the RFID device from the database;

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

comparing the facial image with the retrieved face print; and

at a second checkpoint, re-reading the RFID device and comparing the re-read RFID device at the first checkpoint.

2. The method of claim 1, wherein the data regarding the information of the person comprises a personnel ID and a vehicle ID 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. The method of claim 3, further comprising:

scanning the 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 images, 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; and

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

5. The method of claim 1, wherein if the results after comparisons of the RFID data at the first and second checkpoints do not match, raising an alarm signal indicating a mismatch has occurred.

6. The method of claim 1, wherein the second RFID checkpoint is located near an exit.

7. The method of claim 1, wherein the second RFID checkpoint is located near an entrance.

8. The method of claim 1, wherein the second checkpoint is located near an exit and a third checkpoint is located near an entrance

9. A method for dynamically verifying a vehicle and a person riding in the vehicle at a control gate, the method comprising:

storing information associated with the person'"'"'s RFID tag, wherein the information associated with the person comprises personal information regarding the personnel and vehicle information regarding a vehicle that the person is driving;

at a first sensing point, reading an ID from the RFID tag when the vehicle passes through the first sensing point and sending the ID to a computer for processing;

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

at a second sensing point, re-reading the ID from the RFID tag and sending re-read data to the computer;

retrieving template data corresponding to the data read from the RFID tag at the first sensing point; and

comparing the retrieved template data with data read at the second sensing point to determine whether the template data and the data read at the second sensing point match.

10. The method of claim 9, further comprising:

scanning a face of the person at the first sensing point to obtain a facial image;

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

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

11. The method of claim 9, further comprising:

scanning a face of the person at the second sensing point to obtain a facial image;

retrieving a stored face template from the database corresponding to the read vehicle and personal ID; and

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

12. The method of claim 9, further comprising indicating if the vehicle and the person are authorized entry and if so, directing the vehicle and the person to an entrance when the ID read from the RFID tag and the facial image of the person match with the data and the face template stored in the database.

13. The method of claim 12, wherein the re-reading and comparing are performed at the entrance.

14. The method of claim 9, wherein when either one of the IDs read from the RFID tags and the facial image of the personnel fail to match with data and the face templates stored in the database, the vehicle is directed to an exit.

15. The method of claim 14, wherein the re-reading and comparing are performed at the exit.

16. The method of claim 10, 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.

17. A system for dynamic stand-off verification at a control gate, comprising:

a database for storing data regarding the information of a plurality of individuals;

a first verification device installed at the control gate comprising a first RFID tag reader for reading data from an RFID tag on which information of an individual is stored;

a second verification device installed on at least one of an entrance and an exit, comprising at least one of a second and a third RFID tag readers for reading the RFID tag;

wherein the data read by the first verification device are sent to the computer, and the computer, according to received ID, retrieves data regarding information associated with the at least one individual from the database and determines if the received data matches stored data,

wherein if the data read by the first verification device and the retrieved ID, from the database match, the individual is directed to the entrance,

wherein if the ID read from the RFID tag and the retrieved data do not match, the individual is directed to an exit; and

wherein the data obtained at the first verification device and the second verification device are sent to the computer for processing to compare if these two data match.
