Expert: I have never heard of it. I have heard of "package inquiring".
Moderator: The word "package open" means that no matter whether it is a security door, a password lock or even a safe, he can open it and open a lock in one minute.
Expert: This way, we have not messed up the public security.
Moderator: It is said that a thief hired a "package open" to help him slam the door together. As a result, both of them were sent to the Public Security Bureau, but in any case, it can be seen from this point. : The current lock seems to lock the gentleman without locking the villain.
Experts: This is indeed the case. The emergence of locks has emerged along with the emergence of private ownership. It has been developed for thousands of years. As early as in the Yangshao cultural site in 3000 BC, archaeologists discovered the existence of wooden structures. On the wooden lock, the iron three-spring lock appeared in the year 25 AD. This use was more than a thousand years. Until 1848, American Yell invented the marble lock, which was called Yell Lock or Yale Lock. It is mainly composed of a plurality of marble structures, which are coded by a combination of marbles. At the time it was the best security lock, and it is now the most commonly used lock in the world. It should be said that it has been used for hundreds of years.
Moderator: It seems that the security of these locks can no longer meet the current needs, otherwise those "packages open" will be unemployed.
Experts: In fact, since the 1970s, locks have also developed greatly, with magnetic and remote locks, and locks that use human body features such as fingerprints, sounds, and eyes to break through. The structure of the traditional mechanical lock has high safety performance. Just press your finger lightly and the door at home will automatically open for you. This is because the computer can automatically recognize your fingerprint and no longer need to bring the key. This safe and convenient life may be the scene that can be seen everywhere in the next few years. Human body recognition technology is moving into your life from a secret place in the past.
As shown in the film, human recognition technology is a way to identify identity by certain physiological or behavioral characteristics of the human body. That is to say, once the human body features are stored in the computer, the computer can determine whether the identity of the authenticated person is consistent according to the pre-stored characteristics. Since the selected human body features are unique to each individual, the human body recognition technology is a technology that is specially tailored for the individual.
Moderator: I read a document saying that the weakness of the mechanical lock in the past is that the coding is small, the mechanical opening part is exposed, and the place like this key hole is easily damaged. Is the human body recognition technology able to avoid these problems? .
Expert: You see that there is a simulated door in front of us. This is the door that is usually in and out of the house. This is the (electric) lock that controls the opening of this door. This is the outdoor collection part. This is the indoor control part. This door is opened. It is controlled by this (electric) lock, and this (electrical) lock is controlled by this controller. If this part of the outdoor (collector) is destroyed, it will not affect the (indoor) control part, so I won't open this door, as you can just avoid.
Moderator: How big is its security?
Expert: The safety of the general door lock lies in the code of the key. The best mechanical lock can reach one thousandth, and the fingerprint lock can reach one millionth, which is quite high.
Moderator: Will there be the possibility of fraudulent use of fingerprints, such as copying fingerprints.
Expert: It should be unreal, because in the world we can't find the fingerprints of two people exactly the same, that is, the fingerprints of each of our own fingers are also different. This fingerprint also has one of the biggest characteristics, that is, the fingerprint texture features for life. constant. Now better fingerprint collector can not only sense the temperature of the human body, but also the blood (liquid) flow (moving) in the blood vessels, and it directly collects the fingerprint lines in the dermis layer, so as you said The situation is hard to happen. The working part of the fingerprint lock is roughly composed of three units: fingerprint collection, fingerprint recognition and electric lock. The fingerprint collection part is applied optical technology. When the finger is pressed in the fingerprint collection window, the image is reflected to the camera through a specially designed prism, so the image of the fingerprint is captured, and the captured image is sent to the computer for preprocessing. Get a clear and effective fingerprint image, and then separate the characteristics of the fingerprint. Just like the 箕(ji) and bucket that we usually recognize the fingerprint, the computer can recognize more kinds of features, such as the divergence point or termination point of the fingerprint. Etc., and there are usually hundreds of fingerprint feature points of a finger. According to these characteristics, it is possible to accurately distinguish whether the identity of the identified person is met. If the identity is consistent, a corresponding control signal is issued, and the electric lock obtains a signal. The door will open automatically. Since I am not afraid of losing the key, there will be no embarrassing scenes of not going to the door or rushing to change the lock. In some important departments, such as bank vaults, arsenals, security departments and other important places, hierarchical management can be effectively implemented to avoid the problem of internal piracy. Of course, we can also apply it to e-commerce, which is very popular nowadays. The security of the Internet is guaranteed. When you shop online, you only need to press your finger and protect your password by fingerprint. You can truly rest assured in the virtual world. In the middle of the tour. Each fingerprint lock is equivalent to the performance of a standard PC, and all of this is concentrated in this small space.
Moderator: After watching this film, I feel that the future life is within reach. These things that were only fantasy in the past have been put in front of reality and entered our lives.
Expert: Science and technology are changing with each passing day. In the beginning, because the computing power of the fingerprint recognition technology system is very large, only computers with a microcomputer or more can be realized. In recent years, due to the rapid development of microcomputers, the computing power of general computers has been strong enough, and fingerprint recognition technology has really begun to enter our lives.
Moderator: In the future, smart card recognition technology including various IC cards and bank cards will be replaced by this new fingerprint identification technology.
Experts: This identification technology for the application of IC cards and smart cards is close to the limit of development, and there are also many security risks. Nowadays, the world's biometric identification technology represented by fingerprint identification technology is regarded as the next development climax of smart card technology. In the future, fingerprint identification technology is inevitably very popular. The system using fingerprint identification will be everywhere in our lives. For example, shopping and bank deposit withdrawal can be done by using fingerprint identification and password. Bring you a safe and convenient new life.
