Lock is an old topic and an eternal topic, from early mechanical locks to modern electronic locks and smart locks, to the development of a new smart lock, fingerprint lock, represented by fingerprint recognition in recent years. The development of science and technology and its industrialization penetration have also triggered the revolution of the lock industry, bringing users a high quality of life, work, entertainment and other wonderful experiences and enjoyment from the aspects of safety, convenience, and management. Practically speaking, the development of fingerprint locks is still in its infancy, but it is foreseeable that the expansion of its scale of acceleration will certainly occur in the past few years. Based on the advancement of core technologies, it has already or almost completely broken through the use of thresholds and large-scale industries. The elements are gradually maturing. This is a rare and fast-growing opportunity for the old and evergreen slow-moving lock industry. At present, the smart lock industry, which is still a high-end segment, opens up a new business backbone.
When it comes to locks, it's about talking about keys, talking about security, convenience, and identity theft. The first element of the lock is anti-opening and anti-smashing performance, and the first element of the key is anti-theft performance. The so-called anti-theft refers to the level of security and anti-counterfeiting. The type of key becomes various after the electronic lock and smart lock come out. It has tangible and intangible (such as password), static and dynamic (such as rolling code remote control or fingerprint feature template), and outside the body. There are also many names in the body (such as the biometric characteristics of the human body (the implanted chip does not belong to this type in the strict sense)). The primary purpose of all of these is to enhance anti-theft and anti-counterfeiting performance, and secondly to add additional functions such as ease of use and management requirements. Therefore, the technical development of smart locks will also focus on these to guide technology development at the demand level.
The definition and definition of smart locks is its so-called "smart" features at the technical and functional level, including identification, memory, and learning. In the sense of mass concept, smart locks, ie various types of contact/non-contact/remote control keys/card/lock code locks, and password key locks, can provide unlocking memory and query to facilitate management and security needs, plus The mysterious high-grade and high-density anti-counterfeiting features of such "keys" are important reasons why the public service industry with large mobility is widely used by hotels and other users. Taking fingerprint locks as an example, if privacy factors, special finger fingerprint technology factors, and cost factors are removed, fingerprint locks are more likely to be widely used in such services because they are smarter than what we call smart locks in the mass sense. (Identify memory learning is not fine), it is safe, and it is especially convenient for guests and hotel management and reduces operating costs - the key is no longer needed, and further, if it is considered from the perspective of public safety and security, for example, online chase Escape and security control and so on. Shanghai Pinwei Digital Technology Co., Ltd. exclusively introduces the front-end registered rooms to compare the market demand of the hotel service industry fingerprint lock system. Through the high starting point planning and technical design, it truly breaks through the user experience threshold with high recognition performance. Functional integration gives an economical fingerprint product that fully satisfies practicality. One of the outstanding features of the system is the non-transferable rigid binding of the authorized person, which improves the security level of the guest room, and also provides the record keeping and inquiry of the specific door opener. Although this kind of authorization rigidity also brings about the occasional inconvenience of authorized lending - but it should be noted that authorizing lending is an insecure factor in itself, and in short, it does not hide the benefits. The branded fingerprint safe that is launched at the same time as Pinwei Digital can also be used with the system. It is convenient and safe for the private use of valuables for guest rooms. It is different from the room authorization (of course, the front desk registration authorization), unless the guest himself or other People, including hotel service personnel, have no right to open. Regardless of the room lock or the room safe, Pinwei Digital also sets the read-only feature of the opener record, which fully guarantees the after-the-fact justice when the dispute arises. In this sense, the connotation and extension of the fingerprint smart lock have been integrated and expanded in the real market on the networking level. Of course, all of these are premised on the high reliability of fingerprint protection and fingerprint recognition, which will be discussed in the next paragraph. As a special case, the depth development of mechanical locks also has a certain degree of intelligent features. For example, the Mul-T-Lock invincible lock of the Israeli model emperor company represented by Shenzhen Changen Industrial Co., Ltd. fits the market needs and has three The one-function function (three keys fail), the engineering lock function (the engineering key individual key fails), and the mechanical lock function of the organization lock function (a key opens a lot of different locks), they also have the most Simple even with just a few memory functions.
The development of technology has never been isolated. On the one hand, it depends on the technology itself, on the other hand, it is driven by the interaction between the inherent laws of technological development and the use of the real world. At present, as far as the Chinese market is concerned, the vast majority of smart lock customers are still concentrated in organizing users, such as hotels, institutions, enterprises, etc., and have not yet entered the family. There may be no reason to enter the family, the reason is not the price, perhaps Narrow-domain directional keying dynamic random interactive cipher mode smart lock has this possibility - of course, the premise is that the authorized person needs to memorize the password and the short-term authorized person will not maliciously or transfer the authorization, but the password smart lock can not always remember the real unlock. People's, therefore, their level of security is sometimes greatly discounted. Biometrics can bind authorization to unlockers. In biometrics, fingerprint recognition is the oldest and most reliable identification method supported by long-term practice, especially for live fingerprint collection and fingerprint recognition algorithms. The two core technologies have been greatly improved in the past few years - the former has to solve the problem of effective fingerprint collection and the latter has to solve the problem of reliable identification, especially the deformation of the deformation state, and the various products embedded in the core technology in a large number of application practices. It was tested and basically close to maturity. The strip-shaped semiconductor sliding acquisition in the living fingerprint collection technology is outstanding from antistatic, fingerprint-free residual, durable 10 million times, low power consumption, cost and volume, etc., and is expected to be completely replaced in most applications. Surface pressed semiconductor fingerprint acquisition chip. The recent 4th International Fingerprint Identification Algorithm Contest has shown that Pinwei has entered the international popular list in terms of algorithms for core technologies, and the company has been proactively starting 2 to 3 years before the fingerprint collection of core technologies. With application development, these breakthroughs have enabled the company to stand firmly in the upstream of the industry chain. Embedded products such as fingerprint locks and fingerprint safes have also been launched as demonstration services or self-operated businesses of the company. In terms of optical fingerprint collection, the current living body detection is basically in the primary living body anti-counterfeiting level such as temperature detection and motion detection. For example, latex gloves made using surface release fingerprints can pretend to be tricked by other people's fingers to optical fingerprint locks, but However, it is impossible to deceive the living fingerprint collection of most semiconductor fingerprint sensors. However, there is a company in the United States that is unique in optical fingerprinting. Its multi-spectral imaging penetrates the finger skin and sub-epidermal. It is the optical fingerprinting technology closest to the anti-counterfeiting capability of semiconductors. It is limited to the initial stage of development and its volume. And the cost and other factors, its main application is still in the high-end institutions, military, security and other high-end areas, and whether the volume and power consumption problems can still be solved in the future is still a variable. In summary, the fingerprint lock enters the family for sufficient reasons, and the fingerprint module of the strip semiconductor living body sliding acquisition mode is most ideal for the development of the fingerprint lock. In the first quarter of this year, Pinwei Digital launched a high-performance fingerprint safe with a live sliding collection mode, and will release a super-reliable and cost-effective fingerprint lock product in the upcoming May anti-counterfeiting sliding acquisition mode. In addition to false anti-counterfeiting, Pinwei Digital has greatly enhanced the anti-smashing and non-powerful electronic means of stealing performance of the lock body through the "inside and outside" design.
In view of the diversity of technical products and market demand, mechanical locks and smart locks have their own characteristics, which cater to the different uses of different customers. At this stage, it seems that they will coexist for a long time. The technological development of intelligent locks, ie electronic locks, in the public sense is very mature, and the smart locks under the new concept, ie the fingerprint locks, may take off and the scale expansion period may come soon and be completed quickly. We will wait and see.
