Two Indicators that Need to Know to Choose A Smart Fingerprint Door Lock – Rejection Rate and Falsehood Rate

Smart fingerprint door lock have gradually begun to spread in recent years. In the competition of various smart fingerprint door lock manufacturers in recent years, the quality of smart fingerprint door lock produced is getting better and better, as long as the people who used it said it is very convenient, very easy to use. China is a big manufacturing country. It is a domestically produced non-known brand. In the absence of big brands to intervene in the market, there is a lack of a good certification body to help us choose the brand.

With the popularity of smart locks, we often encounter various problems when purchasing smart fingerprint door lock. Some professional terms like smart fingerprint door lock cannot be understood. For example, what is the rejection rate and the falsehood rate of smart fingerprint door lock recognition? The following is a description of what is the rejection rate and the falsehood rate of the smart fingerprint door lock.

To put it simply, the rejection rate of smart fingerprint door lock recognition is the same fingerprint, which is recognized by the algorithm as different; the false recognition rate of smart fingerprint door lock recognition is not the same fingerprint, and is recognized by the algorithm as the same.

The rejection rate and the falsehood rate of smart fingerprint door lock recognition can also be called rejection rate and false recognition rate. The rejection rate is FRR, which means that the real fingerprint image is considered false. The false recognition rate is FAR, and the fake fingerprint image is regarded as true. The fingerprint rejection rate and the false alarm rate are related to the resolution of the fingerprint head collection window and the fingerprint acquisition method in the fingerprint recognition technology.

The rejection rate and the falsehood rate of fingerprint recognition of smart locks are important indicators for evaluating the quality of fingerprint lock fingerprints. The quality of fingerprint rejection and the rate of false positives directly affect the response time of smart fingerprint door lock and fingerprint recognition. Accuracy, which affects the user experience and the security of the smart fingerprint door lock.

Now the fingerprint heads on the market are all above 500 DPI, which is 500 pixels per inch. In theory, there are 500 information points per inch of fingerprint images for comparison.

The criteria for the rejection rate and the rate of falsehood issued by the Ministry of Public Security were: the rejection rate should be <3%, and the falsehood rate = <0.001%. According to the relevant standards, the security level of smart fingerprint door lock for household entry doors should be level 3, that is, the rejection rate is < 0.1%, and the false rate is <0.001%. The fingerprint resolution used by many smart lock brand advertisements is also within this range. The specific indicators may be different, but as long as it is a brand manufacturer’s product, the user experience will not be far apart.

There is a trade-off between “rejection rate and falsehood rate”. At the same level, the rate of rejection is high, and the rate of falsehood is low, and vice versa. This is an inverse relationship. However, if the level of technology and technology is improved, both of these indicators can be lowered, and in essence, the level of technology should be improved. However, in order to speed up the certification, some manufacturers use the practice of lowering the security level to create fast and recognizable artifacts at the expense of security. This situation occurs in some model locks or demo locks. Everyone should not buy cheaply for some model locks.

For those who are smart fingerprint door locks, the rejection rate and the falsehood rate are shared here today, hoping to help everyone. Yaoertai Technology, professional wireless smart fingerprint door lock technology for more than ten years, smart fingerprint door lock is relatively mature in technology. The technology adopted by the fingerprint smart lock is “electromechanical conversion device”, the “semiconductor” living body identification of the fingerprint identification system, the shell adopts the alloy integrated molding technology, and the surface automobile lamp nano baking paint technology is more wear-resistant and corrosion-resistant, and is a cost-effective fingerprint smart lock brand.
