Many people can see the characteristics of the password function on the password function when purchasing the smart lock. Although the usage of this function can be made as easy to understand as possible in the promotional copy, how can this function be used in the actual application process, and how can the security of the password be guaranteed?
　　 Virtual password technology in smart lock promotion
According to the data, the irregular numbers and letters that most people can remember in a short time are 7 digits. Unfortunately, as long as it is a smart lock with password input function, the length of the verification password is usually 4-6 digits. There are very few smart locks that can set more than 6 passwords. If the password is too long, it is also a problem for memory.
In other words, it is easy for strangers to remember the password when they see the password. Although it is possible to improve security by changing passwords frequently, it is easy to forget the password over time, but it will be more troublesome. Therefore, increasing the length of the password in disguise can also improve security, and the "virtual password" is born to increase the length of the password.
As mentioned above, it is easy to be peeked without changing the password. If you change the long password, the user may not remember it, but if you change the password frequently, the user will not remember it. The virtual password is used in the simplest way. These three shortcomings, the correct password length and content unchanged, add random numbers before and after the correct password, as long as the entire string has a complete and un-divided correct password, you can pass the verification.
Adding a random number before and after the correct password can increase the overall length of the input number, and it will make a large number of people unable to glance at the password. The dummy passwords added before and after the correct password can be arbitrarily changed, which increases the frequency of password replacement in disguise. In this way, the real password will be protected by the dummy password in the "before and after", which improves the security of the real password.
As for the use of the scene, it is definitely in the case of "the surveillance can not easily get rid of the surveillance", in addition to the special and rare cases such as being tracked, more situations are still in front of the acquaintance, Sorry to lock the door in a tight situation. Of course, in this case, the method of opening the door with fingerprints is more concealed and convenient.
Fortunately, although the virtual password technology is not so common, but the difficulty is not so high, and the effect is really good when used, now as long as the smart lock is added to the smart lock on the password input function, the vast majority Both have this "virtual password" function. When using it, be sure to note that the length of the "virtual bit password" is not an arbitrary length. The smart lock will impose certain restrictions on the length of the "virtual bit password" including the real password, so be careful when using it. However, I still hope that you will not be able to use this feature.
Product introduction
Domestic garbage shredding machine is suitable for shredding garbage materials, commonly used shredding machine structure has three main axis, two axis, four axis. This household garbage crusher is driven by planetary gear reducer, and the blade is made of high-strength alloy steel, which has the characteristics of strong wear resistance and high strength. It operates at a differential speed between the shafts and has the functions of tearing, squeezing and biting.
Principle of equipment
The material enters the inside of the shredding box through the feeding system. The box is loaded with shredding blades. The pushing box pushes the material to the vicinity of the blades.
Scope of application
Living garbage shredding machine for all kinds of waste materials and professional design, suitable for crushing all kinds of household garbage, such as old clothes, old shoes, old quilts, waste household items, bags, waste wood, waste plastics, food waste, medical waste, living garbage every day in the life in the breeding, according to the characteristics of the waste material double the production of household garbage shredding machine customer response effect is ideal.
Characteristics of the equipment
Domestic Garbage Shredder equipment output can reach 300-30000 kg/h, according to customer requirements and provide professional design. It has the advantages of uniform discharge, controllable size, large output and low noise. Double star machinery design and production of domestic garbage shredder can be based on the needs of users to replace the internal blade, so as to change the size of finished materials.
1. The material is directly into the shredding chamber for shredding, which is not controlled by the feeding.
2. No tearing at the bottom of the screen, no clogging of materials, etc.
3. The material can be torn up quickly through extrusion shear between two rollers.
4. The domestic garbage shredder can replace the tooth number and thickness of the blade arbitrarily to meet the user's demand for material size.
5. The width and number of teeth of the blade determine the size of the discharge size. The narrower the blade, the more teeth, the thinner the discharge. The wider the blade, the fewer teeth, the thicker the discharge.
