The "intellectual tax" is also called "low IQ tax". It is mainly used to describe some of the money spent on functions or features that seem to be very bullish and actually useless. Popularly speaking, it is "saving money."
Many products have some suspicions of collecting "intellectual tax". The author will come to check out what functions of smart locks are collecting "intelligence tax" to avoid spending more money.
face recognition
That's right, the shou machine's popular facial recognition is collecting IQ tax on the current smart lock. The principle of facial recognition is simply to collect facial feature information and then compare and verify. We can now see a variety of smart shou machines that support facial recognition. Apple used face recognition instead of fingerprint recognition on iPhoneX, which caused a more intense discussion. However, after more than a year of testing, there is no big problem with the security of facial recognition.
So why does the face recognition of smart locks become an IQ tax?
Today's smart locks do not achieve high levels of computing. Since human facial features are very susceptible to facial recognition, facial recognition is often analyzed using a combination of neural network chips (NPUs) and software algorithms to achieve payment level security.
However, after all, the ability of smart lock manufacturers is limited. In actual use, no matter the number of features, the degree of density, the angle, and the processing speed of scanning, there will be a big gap between the smart shou machine and the smart shou machine. Compared with more than one level, the current face recognition smart lock can be said to be suspected of collecting IQ tax.
Of course, technology is still improving. When the consumer-level facial recognition processing capability is greatly improved and popularized, the face recognition on the smart lock will be as safe and convenient as the current fingerprint recognition.
Tiandi hook is now an IQ tax
When purchasing a smart lock, the customer service will ask if there is a heaven and a hook in the door. When installing the smart lock, the master will also recommend removing the heaven and earth hook. As a unique anti-mite measure in China, Tiandi Hook has been installed in many security doors, and the quantity is still very high. So how does the smart lock support the heaven and earth hooks and how to become an IQ tax?
The role of the heaven and earth hook is very simple, that is, adding multiple lock points on the door, greatly reducing the possibility of success. However, compared to violent tricks, thieves who are burglary are more willing to choose technology to unlock - the sound is not easy to find, it is not easy to be suspected by the neighbors, and there is no obvious unlocking, and it will not be very time-consuming and laborious. However, once the technology is unlocked, the lock points will be released together, so many more lock points are useless.
Not only that, but too many lock points will have a lot of troubles in fire safety. For example, when a fire breaks out, firefighters will forcefully enter through violent demolition, because with powerful tools, violent rescue It is a better choice for small casualties.
However, in front of the facade with the heaven and earth hooks, the firefighters will remove the lock points one by one in order to open the door, which is time-consuming and laborious. Therefore, the current world of the hook should not be used as an effective means of security, smart locks do not necessarily have to support the heaven and earth hook.
Although the same smart lock does not have much difference in supporting the support of the world hook, but in the choice of different smart locks, do not choose to give up or give up a smart lock.
"Biometric identification of optical fingerprints" is also an IQ tax
Fingerprint recognition is now very popular, even to the point where it is almost out of date, but the optical fingerprint head unilateral smart lock with "male level" is still on the market, which is not the act of collecting IQ tax, then why? Will also name "optical fingerprint"?
In fact, what I want to say is not the optical fingerprint, but the "biometric" feature of the optical fingerprint head.
Optical fingerprinting works very simply by taking a photo of a fingerprint pressed on a glass. Because the fingerprint is uneven, the lines that come into contact with the glass will be more noticeable. However, this also reveals a problem: as long as the texture of the contact is the same as the fingerprint already entered, it can be verified and there is no "live verification" feature.
The author added the fake fingerprint verification link in the smart lock cross-evaluation. The results show that for the fake silicone fingerprint, the optical fingerprint head is completely wiped out, and the capacitive fingerprint is safely cleared. Including the style of “live detection†in the promotion.
Although the test link mentioned above indicates that the optical fingerprint does not have the ability to prevent false fingerprints, in real life, getting your fingerprint and making a fake fingerprint can be much harder than technical unlocking (mainly when the fingerprint is very hot) Can't move...), so don't worry about security. Just because you collect more money because of "living detection" is an act of harvesting IQ tax.
Summary: Every user is not willing to pay the “intellectual tax†to spend money, but smart lock manufacturers use the disadvantages of consumer information asymmetry, and then use some marketing methods to launch a lot of functions or products with “IQ tax†attributes. .
Product Name:Prestressed hollow square pile mould
Size/Material:steel
Products Description:Prestressed Hollw Square pile mould which is used to produce the hollow square pile, this kind of Hollow square pile in the process of production, it use tension prestressed, reperfusion concrete and then use Centrifugal Machine to spinning the water out, because of this processing that makes reinforced prestressed hollow square pile is higher than other type of pile, at the same time, the pile body used the high strength concrete (C60, C80), high strength steel and high strength concrete in the application of hollow square pile production, make the performance of the pile, the bearing capacity and crack resistance, bending resistance are obtained significantly higher.
Application:Produce prestressed hollow square pile
Technical parameters:F250-F800
