In the field of smart homes, door locks are another broad audience after the lightbulb. A large number of manufacturers have joined the industry very quickly to promote the speed of development, but also allow consumers to have a wide range of products to choose from. In 2014, the scale of China's smart home market reached 28.61 billion yuan, which is expected to exceed 300 billion yuan in 2020, and the market has great potential. It is expected that with the continuous improvement of Internet technologies, “next generation†smart home products will have an invaluable role in the market if they can take the initiative in this market. The status of locks in smart homes can not be ignored. We can not do everything in smart homes. There is a “money map†as long as we grasp them.
The smart home is a residential building. It integrates home-life related facilities using integrated wiring technology, network communication technology, smart home-system design solutions, security technology, automatic control technology, audio and video technology, and builds an efficient residential facility and family schedule. The affairs management system improves home safety, convenience, comfort and artistry, and realizes an environment-friendly and energy-saving living environment. Among them, security technology is an essential technology in smart home systems.
The security protection technology in all applications constitutes a home security system, including: access control, emergency assistance, smoke detection alarm, gas leak alarm, broken glass detection alarm, infrared microwave detection alarm, and so on. Access control is the basic application of the entire home security system.
With the rapid development of digital technology network technology, access control technology has developed rapidly. The access control system has long surpassed the simple doorway and key management. It has gradually developed into a complete set of access control security management system. It integrates automatic identification technology of microcomputers and modern safety management measures. It involves many new technologies such as electronics, machinery, optics, computer technology, communication technology, and biotechnology. It is an effective measure to solve the security management of the entrances and exits of important departments. Confidential department.
The access control system can be divided into the following three categories according to the access identification method: password identification, card identification, and biometric identification. In recent years, with the development of proximity card technology and biometrics technology, access control systems have also achieved a leap-forward development, entered a mature period, and have expertise in security, convenience, manageability, etc., and access control systems. The application area is also becoming wider and wider. However, the most interesting and highest technology content within and outside the industry is biometrics.
Access control biometrics: extremely low cost rate and high security
Due to the human body's unique and non-replicable uniqueness, the biometric key cannot be copied, stolen, or forgotten. Biometrics are more secure, confidential, and convenient than traditional identification methods.
Biometrics can be broadly divided into two categories, physical identification and behavioral identification. Physical features include: fingerprint recognition, vein recognition, palm geometry recognition, retina recognition, iris recognition, facial recognition, DNA identification; behavioral characteristics include: voice and signature recognition, gait recognition. The biometric system samples biological features, extracts their unique features into digital codes, and further composes these codes into feature templates. When people interact with the recognition system to perform identity authentication, the recognition system compares the features with the feature templates in the database to determine whether they match, and thus decides whether to accept or reject the request recognizer.
