Why is access control the foundation of smart home security system?
In the field of smart home, door lock is another product with a wide audience after light bulbs. The addition of a large number of manufacturers has greatly promoted the development speed and also enabled consumers to have a wide range of products to choose from.
China's smart home market will reach 286 in 2014.
0. 1 billion yuan, expected to exceed 300 billion yuan in 2020, with huge market potential.
It is expected that with the continuous improvement of Internet technology, the new generation'
If smart home products can take the lead in this market, they will play an immeasurable role in enterprises and industries.
The position of locks in smart homes cannot be ignored. We can't make every part of smart homes complete. As long as we grasp it, we will have a lot of money'.
Smart home is based on residential buildings, using integrated wiring technology, network communication technology, smart home-
The system design scheme safety prevention technology, automatic control technology and audio and video technology integrate the facilities related to home life and build an efficient management system for residential facilities and family schedule affairs, improve the safety, convenience, comfort and artistry of the home, and realize an environment-friendly and energy-saving living environment.
Among them, security technology is an essential technology in smart home system.
The security technology in all applications constitutes the home security system, including: access control, emergency help, smoke detection alarm, gas leak alarm, broken glass detection alarm, infrared microwave detection alarm, etc.
The entrance guard is the basic application in the whole home security system.
With the rapid development of digital technology and network technology, access control technology has developed rapidly.
The entrance guard system has already surpassed the simple doorway and key management, and it has gradually developed into a complete entrance guard security management system.
It integrates microcomputer automatic identification technology and modern safety management measures, and involves many new technologies such as electronics, machinery, optics, computer technology, communication technology, biotechnology, etc, it is an effective measure to solve the problem of security management at the entrances and exits of important departments, and is applicable to various confidential departments.
Access control systems can be divided into the following three categories according to the way of entry and exit identification: password identification, card identification and biometric identification.
In recent years, with the development of induction card technology and biometric technology, the entrance guard system has also developed rapidly and entered a mature period. It has its own advantages in safety, convenience and ease of management, the application field of entrance guard system is also more and more extensive.
However, biometrics is the most interesting and most scientific in and out of the industry.
Access control biometric identification: the cost rate is extremely low and the security is extremely high. Due to the inherent non-replicable uniqueness of human body characteristics, this biometric key cannot be copied, stolen or forgotten, biometrics is more secure, confidential and convenient than traditional identification methods.
Biometrics can be roughly divided into two categories: physical feature recognition and behavioral feature recognition.
Body features include: fingerprint recognition, vein recognition, palm geometry recognition, retina recognition, iris recognition, face recognition and DNA recognition;
Behavioral characteristics include: voice and signature recognition, gait recognition.
The biometric system samples biological features, extracts their unique features and converts them into digital codes, and further forms these codes into feature templates.
When people interact with the recognition system for identity authentication, the recognition system compares its features with the feature templates in the database to determine whether the two match, thus deciding to accept or reject the request for recognition.
