In daily life, the application of passwords is more and more widespread, from computers to mobile phones to password locks at home, everywhere. However, there are also many people who are worried about this: Is the fixed password of the combination lock really safe? In reality, various deciphering methods make our intelligent life encounter difficulties.
For code locks, some users have raised the question: the secret of code locks is fixed and unchanging. If a thief hides in a corner while opening the door and peeping out, he gets down several times and secretly writes down my home code lock. The order of the passwords, so next time I am away, he can easily burglary.
This sounds really bad. In response to users’ concerns, Zhuoju Smart Home has launched a more secure "virtual password technology" to completely solve the hidden danger of password peeping.
The "virtual password technology" is to add any number of digits before and after the correct password. As long as there is a continuous correct password in the middle, the door can be opened, which can effectively prevent the password from leaking.
Only need not change the real password sequence, insert multiple numbers before and after or in the middle to unlock the lock. For example, if the correct password is 123456, you can add (8)(6)(7)123456(0)(2)(3) when you enter it. Note that the brackets are other numbers added.
Compared with fixed passwords, virtual passwords have a higher security level and are more difficult to be spied on. Therefore, the risk of password leakage is less, and the length of the password is increased at will. Each time the password is changed, the security of the password can be greatly increased, and it is more difficult for a thief or a thief Get the real password.
So is there a maximum limit for virtual passwords? Yes, it depends on the length of the password set by the manufacturer of the smart door lock. For example, the maximum set password limit is 20 digits, so the total length of the virtual password and the password cannot exceed 20 digits.
Compared with fixed passwords, virtual password technology is undoubtedly more secure, but is it unbreakable? No matter how high the security level of virtual password technology is, there is still a risk of leakage. Through multiple snooping of the password input, the password numbers can be integrated and compared to find the intersection between the arrays, so as to obtain the real password and crack the door lock password.
Therefore, the security of false passwords is also relative, and the user is more troublesome when entering, which slightly increases the efficiency and difficulty of input, but if you remember the original password, these small problems can basically be ignored.
The security of password locks is not high. Therefore, the core of fingerprint locks or other biometric smart locks is fingerprint unlocking or other identification methods. Password unlocking is generally used as a side function. Biometrics has higher security and is also important for smart locks. One of the development directions.
At present, most smart locks on the market have multiple unlocking functions. For security requirements, door locks with virtual password technology are the first choice for purchase. In normal use, it is also recommended to use fingerprints, mobile phone remote control and other methods to unlock, use less or no password to unlock, and mechanical keys to unlock.
