Smart door locks have been rapidly increasing since 2016 because they have met both the convenience of users and the improvement of management efficiency of operators.

According to the recent "2017-2020 China Smart Door Lock Technology and Application Market Analysis Report" released by Siruida Consulting, the market size of smart door locks (with biometric identification or networking function) is close to 8 million in 2017, and is expected to be 2020. There will be more than 60 million smart door locks in the year, with annual growth rates exceeding 100%.

At present, fingerprint recognition technology in the home application has basically become a standard. In addition, the smart product circle learned in market research that in the apartment market, especially short-term rental apartments, the public security department has been promoting the application of fingerprint locks, and managing the mobile population with the accuracy of fingerprint identification for personal identification. Fight against fugitives, drug abuse, gambling and other criminals and social security crimes.

For example, last year a well-known short-term rental platform company was fined 40 million by the public security department for related incidents. Therefore, the apartment operator is also very motivated to install a fingerprint lock on the rented house it manages to avoid the inability to confirm the tenant identity. Joint legal responsibility.

This is undoubtedly another major market advantage for fingerprint recognition technology.

Smartphone vs smart door lock two paths of a technology

As a convenient and mature identification scheme, fingerprint recognition is accepted by ordinary consumers due to its widespread popularity in smartphones. However, fingerprint module companies have reached a consensus that the mobile phone market is basically saturated, and there is an urgent need to explore emerging market segments.

It should be pointed out that although fingerprint recognition is a unified technology, it is basically two things between different application areas.

Yajie, director of R&D director of smart door locks, told the smart product circle reporter: “Considering that mobile phones are generally only used by individuals, the fingerprint identification scheme in mobile phones often reduces the parameter setting of image matching degree in order to recognize the speed and recognition rate. The solution is also possible on mobile phones such as private items, but it cannot be directly translated into an open security product such as a smart door lock."

Li Yangyuan, the founder of the "texture phase" fingerprint recognition algorithm and the inventor of the capacitive fingerprint sensor "CQT" circuit technology, and the chairman and chief technology officer of Suzhou Mindray Microelectronics Co., Ltd. also said: "When we talk about the security industry, military civilian use The boundaries of the community are relatively vague, and many community security and public security systems are equally strict with security control. Simply put, what is security? We really care about it, if we don’t make it, we will have a big loss!"

It can be seen that the requirements for fingerprint recognition technology in different applications are completely different, so that its technical composition, technical form and scheme design may be very different.

Smart door locks need to be strictly guarded by "security" attributes

Under such an application category of smart door locks, the consideration of fingerprint recognition must be security level, not consumer level, involving life safety. When enterprises choose a fingerprint identification solution provider, it is best to refer to the technical solutions that have been approved by the application market of high security level such as banking system and public security system.

Figure: The overall security concept of fingerprinting

The security of fingerprint identification is a system concept. In addition to the two basic parameters of the rejection rate and the falsehood rate, there are requirements for applicability, robustness, and anti-attack capability.

Applicability refers to the availability of special fingerprints. It cannot be used in the case of special people such as the elderly and children, or the recognition rate is significantly reduced.

Robustness means that the recognition rate is significantly reduced due to natural changes in human fingerprints, because the human epidermis is replaced every month due to metabolism, and the impact of this natural change on fingerprint recognition needs to be considered in the scheme. .

Anti-attack capability means that the solution can resist a certain degree of attack on four levels of fingers, sensors, processors, and system networks. The "fake fingerprints, living recognition" often mentioned in the mass media is only an attack on the level of the finger, while attacks at other levels have not attracted enough attention in the industry.

On November 21st, the “Safety Fingerprint Life” technical seminar hosted by Suzhou Mindray Microelectronics Co., Ltd. will be held in Shenzhen. The event invited heavyweight guests from the three departments of Public Security, Shenzhen Graduate School of Tsinghua University, Shenzhen Sanhuan Electronics, Shenzhen Gaoyu Chemical Materials, Shanghai Lisheng Biological, etc., to focus on “IoT Security for Fingerprint Identification Industry Security”. The impact of sexual norms, "analysis of the latest development trend of global fingerprint identification core technology and technology", "fingerprint challenge system security challenges and breakthroughs" three dimensions, a total of fingerprint identification security applications.

Li Yangyuan said: "For the fingerprint identification solution for security applications, the three parameters of safety, quality and precision are very important, and they are also fraudulent. We don't play the concept of gimmicks or speculation in this event, and actually invite the industry. Upstream and downstream partners, I hope to speak with facts and talk about the topic of fingerprint identification security once!"

The agenda is as follows:

Split Encoder

Motion Control Sensor is an original part that converts the change of non-electricity (such as speed, pressure) into electric quantity. According to the converted non-electricity, it can be divided into pressure sensor, speed sensor, temperature sensor, etc. It is a measurement, control instrument and Parts and accessories of equipment.
