Is fingerprint lock better than password lock? With the intelligent life now, many people have replaced the ordinary locks at home with fingerprint locks or password locks, which is more convenient and safer. So, is fingerprint lock better than password lock?
Is fingerprint lock better than password lock? 1 (1) Fingerprint locks and password locks are more convenient than mechanical locks.
Fingerprint locks and coded locks belong to electronic locks. There are many more electronic components than mechanical locks, and there are more ways to unlock them. Fingerprint locks mainly rely on people's fingerprints to open doors, and password locks mainly rely on entering passwords to open doors. In either case, you don't need to take the key to open the door. With the gradual popularization of home smart locks, two unlocking methods are still the most popular ways to open doors.
(2) Fingerprint lock is better than password lock. In the past, fingerprint locks and password locks were not particularly secure, but they often appeared in the same lock.
Even so, if compared, fingerprint lock is better than password lock. Because the fingerprint lock only needs to click the fingerprint on the fingerprint lock head, and the password lock needs to input a series of numbers, the unlocking efficiency is low. And the password lock needs to remember the password, which is used by a family. If it is a new password, it will be more troublesome to start using it. But if you enter fingerprints, the family does not have such a big threshold for use. Another problem with password locks is that if the password is read, it is easy to open the door. Of course, in terms of security, the previous fingerprint lock is not necessarily much higher than the password lock, because most of the previous fingerprint locks use optical fingerprint heads, so it is easy to be opened by copied fingerprints. Fingerprint and password are often unlocked in the same lock, which can avoid the situation that only one lock can't be unlocked-this is the case with the smart lock of glass door below. In addition to the design of semiconductor fingerprint head and virtual password, the security has been improved.
(3) Today's smart locks are easier to use, more complex and safer than simple fingerprint locks and password locks.
Smart lock (also called fingerprint lock in many cases now) is the evolution form of fingerprint lock (referring to simple fingerprint lock) and password lock. Nowadays, smart locks generally adopt "five-in-one" unlocking methods: fingerprint (semiconductor biometric fingerprint head), key (mechanical key of class C lock core), password (virtual password) and ic card (choose safer IC card instead of magnetic card).
Is fingerprint lock better than password lock? Two characteristics of fingerprint lock:
I. Security
Fingerprint lock is a security product produced by the precise combination of electronic components and mechanical components. The essence of fingerprint lock is nothing more than safety, convenience and fashion. Rejection rate and misidentification rate are undoubtedly one of the most important indicators, which can also be called rejection rate and misidentification rate. There are several expressions at present:
The resolution of the fingerprint head used, such as 500DPI. The accuracy of the existing optical fingerprint sensor is generally 300,000 pixels, and some enterprises use 6.5438+10,000 pixels.
Expressed as a percentage: for example, what is written on some parameters. Of course, these are the publicity parameters of various enterprises, whether it is 500 DPI or rejection rate.
The sentence "The rejection rate of truth and the recognition rate of falsehood are mutually changing" is correct to some extent. This seems to be the concept of "hypothesis testing" in mathematics: at the same level, a high rejection rate of truth is a low recognition rate of fallacy, and vice versa. This is an inverse relationship. But why is it correct to some extent? Because if the technology and technical level are improved, these two indicators can be lowered, so the essence should be to improve the technical level. In order to speed up the authentication, some manufacturers lower the security level at the expense of security, thus creating a fast, strong recognition of the false image. This is more common in sample locks or demonstration locks.
According to relevant standards, the security level of fingerprint anti-theft lock at home entrance door should be three, that is, the rejection rate is ≤0. 1% and the recognition rate is ≤0.00 1%.
Second, it is durable.
Theoretically, one more function means one more program, so the product is more likely to be damaged. However, this is a comparison between manufacturers with the same technical strength. If the technical strength is high, their products can complete more functions and better quality than those with poor technical strength.
The more crucial point is: the comparison between the benefits of multiple functions and the risks brought by functions. If the function brings great benefits, it can be said that this increase is worthwhile, just as it is the same reason that if you drive at a speed limit of 100 yards, it is necessary to pay the price of violation or accident if you step on the accelerator again. If this function can't bring you any benefits, then this function is redundant. So the key is not to consider what "one more function means one more risk" but that the risk value is not worth taking.
Just like the networking function, on the one hand, the industry is not sure about the stability of fingerprints in the process of network transmission, on the other hand, if the existing decoration is destroyed, and more importantly, once it is invaded by viruses, there will be no "medicine" to cure it. Once connected to the network, the possibility of being attacked will greatly increase. However, security technologies such as telephone alarm need to set up related equipment separately, which has the problems of indoor radiation and false alarm. Especially the latter, due to external factors such as technology and environment outside the fingerprint lock itself.
Third, anti-theft
According to the classification of anti-theft performance, popular fingerprint locks are divided into ordinary fingerprint locks and anti-theft fingerprint locks. There is not much difference between the ordinary fingerprint lock and the original electronic lock, which mainly adopts fingerprint authentication, but it cannot be used on the existing security doors in China. This kind of fingerprint lock has no hook of heaven and earth pole, so it is impossible to use the world anti-theft system of security door (some imported fingerprint locks on the market do not meet the national industry standards and can only be used for wooden doors).
Fingerprint anti-theft lock has better security and can be applied to standard anti-theft doors and wooden doors. This lock can automatically or semi-automatically connect the lock system with the world of the security door without affecting the performance of the original security door.
Different anti-theft performance, the market price is also very different. The price of fingerprint lock with mechanical anti-theft function is obviously higher than that of ordinary fingerprint lock without heaven and earth anti-theft function. Therefore, when consumers buy fingerprint locks, they should first choose the corresponding locks according to your door. Fingerprint locks are generally selected according to the use requirements.
Choose different fingerprint locks for different purposes, and choose anti-theft fingerprint locks for home use, which has low requirements for doors, does not need to be modified, and is convenient for after-sales maintenance. Engineering fingerprint locks are generally purchased in bulk, and the door factory can be required to provide supporting doors that meet the same direction of product installation. Therefore, there is no modification problem, but there will be some trouble when the ordinary anti-theft lock is repaired or replaced in the future, and it will not match the new lock. Generally, the most direct way to distinguish fingerprint lock from engineering fingerprint lock and household fingerprint lock is whether the length and width of the rectangular lock body side strip (guide plate) under the doorknob lock is 24X240mm (main specification), and a few are 24X260mm, 24X280mm and 30X240mm, and the distance from the center of the handle to the door is generally about 60mm. Simply put, it is to directly install the general security door without moving the hole.
Password lock function:
The structure should be relatively simple, although not as simple as the marble lock, but at least as reasonable and simple as the recording movement.
High reliability.
In the aspect of preventing attempted unlocking, a simple interface can be attached to the motorcycle lock to prevent attempted unlocking by giving an alarm.
The operation must be simple. Using the operation mode of touch-tone telephone, you can unlock the lock by pressing a few keys one by one. If you use a six-digit password, just press the key six times. Some mechanical key digital locks are expressed by the number of times the key is pressed by the electric car lock. For example, for the password of 999, you need to press three keys 9 times ***27 times, and it will be more inconvenient to operate with more digits.
Changing the password must be easy for the owner. In order to choose a group of passwords that are easy to remember, the arrangement of optional password groups must be continuous. Take a four-digit code as an example. You can choose any of the 10,000 passwords from 0000 to 9999, and none of them is useless or not optional.
The unlock password must be unique among all password groups in order to have the maximum number of keys. According to some published patent information, some mechanical coded locks use several keys (digital keys) to input the unlocking password at the same time, and the order of the passwords is irrelevant, for example, 82 1 can unlock, while 8 12, 128,182,21. The sequential input method has the requirement of numerical order, and the number of keys is the largest. If ten numeric keys from 0 to 9 are used and six passwords are used, the sequential input method can have one million passwords, and the number of keys is large enough.
Is fingerprint lock better than password lock? 3. Advantages:
1, password fingerprint lock and mechanical lock cylinder are classified into ABC safety levels. From the lock core alone, the lock safety of the same level is similar.
2. In terms of convenience, according to different functions, fingerprint locks can also be unlocked by means of fingerprints, passwords, credit cards, mobile apps, etc. Convenient. There's nothing to say.
3. In terms of intelligent anti-theft, it has anti-theft alarm function and remote monitoring function, which is equivalent to an active anti-theft compared with the traditional door lock.
Having said that, I'm going to replace my security door with a password fingerprint lock, but for impulsive consumption, let's talk about its shortcomings.
Second, the shortcomings:
1, the market is mixed and the quality is difficult to distinguish.
2. The password fingerprint lock cannot be copied, but the card unlocking method is easy to be stolen.
3. The anti-pick alarm function needs to be customized, and not every model has this function.
4, the overall price is higher than the mechanical lock, and the cost performance is relatively low.
5. Compared with mechanical locks, the wear is larger.
In fact, no matter what locks are at risk of being stolen, no matter how high the level of the lock core is, there is also the risk of being violently unlocked. Choosing a password fingerprint lock can give more consideration to the advantages of convenience.
Having said the advantages and disadvantages of the password fingerprint lock, the person you like is definitely going to change the lock, but you can't buy the password fingerprint lock with your eyes closed.
Third, what are the points for attention when purchasing smart locks?
1, not the more functions, the better, but the complexity of the functions gives the criminals a chance to destroy;
2. Choose a brand with perfect after-sales service, and don't be confused by some superficial publicity;
3, don't care too much about the appearance, the good quality of the password fingerprint lock is the last word.
