Is the password fingerprint lock safer?

Speaking of fingerprint locks, is it safe? You can only answer that any lock is not absolutely safe. It depends on who opens it and how to open it. There is a piece of news: A locksmith decodes Rolls Royce in 20 minutes, and millions of Rolls Royce can open it. Therefore, there is no fingerprint lock manufacturer to guarantee that the fingerprint lock produced cannot be cracked. It can only be said that the prevention level has improved and the technology opening time has been prolonged, so the thieves generally will not damage it, because they know that the more time, the greater the exposure.　　 Password fingerprint lock security at home can be divided into lock body security and electronic system security. There are also three parts: network security. The security of the lock body can be said to be what you pay for. This can only depend on the grade you bought. For example, some lock tongues do not prevent jamming, some do not prevent cat eyes from opening, and some lock cylinders do not reach Class C.　　 The current security of electronic systems mainly includes fingerprint unlocking, password unlocking, Bluetooth unlocking, and nfc card unlocking. In fact, password unlocking is the most secure, because in order to facilitate memory, only 6 valid passwords are often set, and then it is easy to leave fingerprints on the keyboard for people to peek. The most important thing is that it takes time, as well as electromagnetic shielding capabilities and switch lock logic, all of which require cost and experience. There is also nfc unlocking, because Taobao is flooded with a large number of nfc card copying devices. Although nfc can be encrypted and complex algorithms can be set up, these all require cost. Lock merchants often try to use public versions to reduce costs. The main problem is When Ma Dahaai forgets things and loses things, he misses big things. Speaking of fingerprint unlocking, this requires at least the security of the live fingerprint unlocking to have a basic guarantee. If it is an optical sign-in machine, the fingerprint sticker purchased online can be cracked, and the live fingerprint is basically achieved. It basically requires the FBI to meet the iPhone standard. The ability to crack.　　 The last is network security. Nowadays, smart locks generally support functions such as networking, remote sending of passwords, and remote unlocking. However, due to cost and technical limitations, WiFi access methods are often used. With the development of WiFi technology up to now, network speed has made considerable progress, but compared with the new communication protocol, security has many loopholes.　　The main purpose of using the fingerprint lock is convenience. As for whether it is safe or not, everyone's approval is needed. Password fingerprints are safe, but the current locks embedded in them are not safe, because this kind of lock will fail instantly after a high-voltage pulse, so it is best to use a mechanical lock before the technology is fully mature. If you are sure to use an electronic lock, you should also buy an electronic lock produced by a major manufacturer that can withstand electrical shocks. This is more assured.
