Familiar with intelligent locks, see how security has a "lock"


Speaking of security, I am afraid that the first thing people think of is security monitoring equipment, whether it is a variety of forms, or different characteristics. All bring more convenience to people. However, in addition to security monitoring, there are actually a lot of equipment, as well as many characteristics and types, in people's casual, silently guarding people's security. Among them, smart lock is such a model.


With the continuous development of smart locks, its own technology is undergoing new and updated generations. Then, in the process of change, what are the advantages of different smart technologies, and what are the needs for everyone? Let's take a brief look at the different smart electronic door locks, which have different strengths.


Password lock, the most original smart lock


Speaking of the password lock, it can be said that it is the earliest and the most primitive kind of smart lock. In use, the user only needs to input the corresponding password of the gate when the need to open, and the control of the gate can be completed. However, with the continuous advancement of technology, such locks have also undergone a rich development. At present, in the large category of password locks, there are ordinary password locks formed by simple electronic circuits, and there are also password locks based on integrated circuits that have high defense performance. Of course, for now, the most widely used is the integrated password lock with integrated circuit as the core and controlled by manually programmed programs.


In fact, speaking of the advantages of the password lock, compared to the mechanical lock is certainly not a little higher. For the user in use, the user's password can be changed at any time to prevent the password from being stolen, and the password insurance factor can be prevented from being lowered due to too many people entering and leaving. When the password is entered multiple times, the alarm system will automatically start, so that the security of the door lock is not reduced at all times due to the long time of use.


However, password locks also have very obvious shortcomings in use. For example, the password is easily stolen by people, and the password keyboard is at risk of being damaged or destroyed. For the user, there is also a problem that the password is forgotten and the operation is troublesome. Therefore, this is also the place where the password lock is in the application and hinders the user's trust.


Induction card lock, the most common access control insurance


Speaking of the proximity card lock, I am afraid that everyone will not feel strange. Whether it is a hotel or an ordinary residential building, most of the IC card-based access control systems are used. As for why the IC card-type access control is such an audience, I am afraid it is still due to the strong confidentiality and low-cost manufacturing process of the IC card. So for a long time, it has been favored by everyone.


In the history of proximity cards, there are two types, contact IC cards and contactless IC cards, which we have previously described in detail. Also, since the contact area of the contact type IC card is often exposed to the surface of the card, it is easier to be copied, so the current type of the card is more conveniently implemented with a more convenient and safe contactless card.


Compared with the contact type IC card, the contactless card can effectively avoid damage to the card due to external friction, and at the same time, there is no direction in use. Therefore, it can be more convenient in use. In addition, in the authentication, most of the cards currently use multiple password protection, and in some key links, the IC card can also use the non-storage password confirmation function, which is safer than the ordinary password. More stable.


Of course, the IC card type door card is not seamless, its high cost and unique use also bring a lot of confusion to users and manufacturers. However, in terms of security, it can be said that it has long been a leader in civilian security.


Fingerprint recognition, ready to usher in a new era


With the recent rapid development of biotechnology, fingerprint recognition is also more used in our lives. Whether it is a fingerprint attendance machine or a fingerprint verification lock, it has long been common in our lives. And if you introduce smart door locks into biometrics, you can undoubtedly bring smart door locks into an era of renewal.


In fact, for the security of fingerprint recognition locks, we certainly do not have to repeat too much. If this technology works well, it can almost be said to raise the security recognition to the highest level. However, although the fingerprint recognition algorithm currently used on the PC is relatively mature, the algorithm suitable for use on various embedded systems still has a relatively large development space. Since the processing resources and memory resources that can be used in the embedded system are very limited, when the fingerprint algorithm is transplanted into the embedded system, it is necessary to make a compromise between the recognition performance and the use cost, so the embedded fingerprint recognition algorithm Development has become one of the difficulties in the development of fingerprint products. So, although fingerprint recognition brings us almost the highest level of protection, if we really enjoy mature security, we still need more time and patience.
