Theft of a car cannot be completely eliminated, but we can take some measures to reduce the probability of occurrence. This week's week-long program show Xiaobian introduces you to a car anti-theft fingerprint lock program. If you are knowledgeable, please feel free to leave a comment.
Before the opening of the eight, let's talk about the classification of car alarms and their respective advantages and disadvantages. Car anti-theft generally has these categories: mechanical lock anti-theft, electronic anti-theft system, keyless entry system, network anti-theft and bio-theft.
1, mechanical anti-theft
The main principle of mechanical anti-theft is to lock a certain machine on the car, so that it can not play its due role, such as transmission block lock, steering wheel lock, brake pedal lock, etc., the price from tens of dollars to several hundred dollars Not waiting. It can extend the theft time, but it can't issue an alarm. There are many ways to crack it. Suitable models: low-end mini cars, vans, etc...
2, electronic security
Electronic anti-theft mainly relies on the use of wireless signals and chip passwords to lock the ignition or start to achieve the purpose of anti-theft, and has anti-theft and audible alarm functions. This is the most anti-theft method currently used in the market. For example: various remote controls and chip keys.
Advantages: easy to operate
Disadvantages: 1. The signal of the remote control is easily interfered, intercepted and cracked; 2. It is easy to falsely report and disturb the people; 3. It does not have the right to use the function.
The car theft process: first use the remote control interceptor to copy the original car remote control, open the door, enter the car with a decoder to decode, and then start the car can be driven away. The whole process is less than 1 minute.
3, keyless entry system
The keyless entry system replaces the remote control with a smart card, and the key is cancelled with the start switch inside the car.
Advantages: Simple and convenient operation.
Disadvantages:
1. The vehicle anti-theft system emits wireless signals from time to time. Once the signal transmission between the anti-theft system and the smart card is affected, the vehicle will turn off.
2, product quality is not closed. It is easy to cause problems such as failure to start or failure to extinguish.
3. The keyless entry system uses wireless signals and may be interfered with, copied and intercepted.
4, network anti-theft system
The network anti-theft system mainly relies on the GPS/GSM network signal to lock the ignition or start to achieve the purpose of anti-theft. At the same time, the satellite information system can be used to transmit the alarm information and the location of the alarm vehicle to the alarm center silently.
Advantages: easy to operate, many features
Disadvantages: There is a blind spot in the GPS/GSM network signal. In the blind spot area, the GPA/GSM signal cannot be interfered with the vehicle. The signal shielding device is small and concealed.
The above several solutions can not be separated from the key and the remote control and the smart card, so there are various keys, remote controllers and smart cards that are lost and copied, leaving the thief with an opportunity.
Today, we introduce the fifth type of car anti-theft - biometric anti-theft.
The biometric anti-theft system uses the human body feature as the only key to unlock, and has a car fingerprint activation controller and a vein scanning controller. Taking fingerprint activation as an example, it utilizes a large amount of information carried by human fingerprints, and the coincidence rate of each person's fingerprint is almost zero. In the system, the information of the owner's fingerprint is stored in advance, and the vehicle can be started after verification by the fingerprint.
Suitable models: luxury high-end cars, luxury car SUV...
Automotive fingerprint lock market overview
Many merchants have seen the huge business opportunities and unlimited market potential of car fingerprint locks. Everyone has started to produce and sell a technology, and they don’t want a piece of technology. For ordinary consumers, car fingerprint locks are still an emerging high-tech product. It is difficult for everyone to really understand and understand in a short period of time. They can only listen to the propaganda and introduction of the merchants. Although the methods of propaganda of various businesses have their own advantages, the content is almost the same: all in one is the living fingerprint identification, the patented product, the FPC sensor imported from Switzerland, the optical sensors of the first generation, and so on. Then they are jealous of each other.
Overview of car fingerprint lock scheme
The scheme uses the large amount of information carried by the fingerprint and the fact that the coincidence rate of each person's fingerprint is almost zero. The fingerprint information of the owner is stored in the system in advance, and the identity is verified by the fingerprint comparison before the vehicle can be started. Compared with traditional locks, fingerprints can completely solve the problem that traditional locks such as key loss, mutual opening, decoding, interception, copying and key stealing cannot be cured.
Working principle diagram
Anti-theft principle:
The central controller controls the car computer, door lock, engine, oil circuit, original car anti-theft system, electric control cover lock, electronically controlled gearbox lock, electronically controlled direction lock, electronically controlled trunk lock and other equipment. Since the car fingerprint locks are all wired encrypted data transmission, there is no wireless signal, so those cracking tools for wireless signals are not useful for car fingerprint locks. If you want to crack it, you can only dismantle it. It is useless to dismantle a single line. The system controls the whole car, so you must find the central controller, and then remove it and then restore it, so that it is possible to drive away. The central controller is installed in the engine compartment, and the cover lock is electronically controlled. If the door that is not opened by fingerprint verification is illegally entered into the vehicle, the switch for forcibly pulling the motor cover lock is useless. The central controller cannot be removed without opening the engine compartment cover. If the central controller is to be operated, the fingerprint controller will only send a signal to the central controller after fingerprint verification. At this time, the central controller will work and the vehicle's anti-theft system will be released. Therefore, the famous car fingerprint lock is absolutely safe and reliable. Even if the installer does not have a fingerprint, it can't be cracked or removed.
In addition, the temperature-sensing fingerprint sensor used in the scheme utilizes a fingerprint image constructed by a small temperature difference data between the peak of the finger of the blood circulation and the valley of the blood, in addition to having a high recognition rate for the ideal fingerprint, it is difficult Fingers also guarantee a very high recognition rate, such as: dry fingers, wet fingers (squeezing fingers), light textured fingers, worn fingers, rough fingers, old fingers, grease fingers, dust fingers, mud fingers, ink fingers, Peeling fingers, baby fingers, etc., can be quickly verified, very convenient.
No matter whether it is a flat fake fingerprint or a three-dimensional fake fingerprint, it cannot be verified, because there is no temperature difference between the flat and the three-dimensional fake fingerprints. Only the fingers with blood circulation, the temperature difference between the peaks and the valleys .
