Abstract

A vehicle security system includes a trigger module, an image acquisition module, a microprocessor and a database. The trigger module triggers the image acquisition module to capture a pupil image of a proximal party triggering the trigger module. The database is coupled with the microprocessor and stores at least one pupil image of an authorized user. The microprocessor includes a comparison module and a response module. The comparison module compares the pupil image captured by the image acquisition module with the stored pupil image in the database and generates a result notification to the response module. The response module implements an appropriate responsive action to lock or unlock the vehicle according to the determination. The disclosure further provides a method for vehicle security.

Claims

1. A vehicle security system, comprising:

a trigger module;

an image acquisition module, the image acquisition module is adapted to capture at least one pupil image of a proximal party triggering the trigger module;

a microprocessor comprising a comparison module and a response module; and

a database, the database is coupled with the microprocessor, wherein the trigger module triggers the image acquisition module, the database stores at least one pupil image of at least one authorized user, the comparison module compares the pupil image of the proximal party captured by the image acquisition module with the stored pupil image in the database and generate a result notification to the response module, the response module makes a determination as to whether or not the pupil image captured by the image acquisition module matches with the at least one pupil image stored in the database according to an output signal which is the comparison result, and generate an appropriate corresponding responsive action to lock or unlock the vehicle responding to the determination.

2. The vehicle security system of claim 1, wherein the trigger module comprises an infrared induction device.

3. The vehicle security system of claim 1, wherein the trigger module comprises an induction device disposed on the handle of the vehicle door.

4. The vehicle security system of claim 1, wherein the image acquisition module comprises a camera and an illumination device.

5. The vehicle security system of claim 4, wherein the illumination device is an infrared illumination device.

6. The vehicle security system of claim 4, wherein a brightness of the illumination device changes periodically.

7. The vehicle security system of claim 4, wherein the image acquisition module further comprises a position adjusting device on where the camera and the illumination device are fixed.

8. The vehicle security system of claim 1, wherein the comparison module compares the pupil image captured by the image acquisition module with the stored pupil image in the database by calculating a similarity between the captured pupil image and the stored pupil image in the database, and the output signal is the similarity calculated by the comparison module.

9. A method for vehicle security, comprising:

creating a database storing at least one pupil image of at least one authorized user;

capturing at least one pupil image of a proximal party attempting to open the door of the vehicle;

comparing the captured pupil image with the stored pupil image in the database;

determining if a matched pupil image is found in the database; and

unlocking the vehicle if the matched pupil image is found in the database.

10. The method of claim 9, wherein the step of determining if a matched pupil image is found in the database comprises:

determining the matched pupil image is found if the similarity between the captured pupil image and the at least one stored pupil image in the database exceeds or equals a preset value; and

determining no matched pupil image is found in the database if the similarity between the captured pupil image and each pupil image stored in the database is less than the preset value.

11. The method of claim 9, further comprising inquiring the authorized user whether to start the engine and the power system of the vehicle after the step of determining if a matched pupil image is found in the database.
