Remote control electronic anti-theft lock
At present, the common remote-controlled electronic anti-theft locks mainly include optical remote control and radio remote control. The optical remote control is further divided into an infrared remote control and a visible light remote control. The optical remote control utilizes a narrow angle optical transmission password, and the advantage is that the amount of information transmitted can be large, the speed is extremely fast, the human eye can not recognize it, and cannot be in the light path (operator and The electronic anti-theft lock between the main body) attempts to copy with the instrument capture signal, so the confidentiality is extremely high. The advantage of radio remote control is that the amount of transmitted information can be large, fast, and the human eye can not recognize it, but the transmitted signal is scattered and easily captured by the instrument. Therefore, it is suitable to adopt a "changing password", such as the so-called "hopping code". "Rolling code" (both are random changes without obvious laws), so that even if the signal at the time is captured, there is no value of utilization and copying. The use of a remote-controlled electronic anti-theft lock requires careful storage of the remote control (ie, the key), and for some applications, the key is a bit larger and may require the use of a specific battery.
Keyboard type electronic code lock
From the current technical level and market recognition level, the most widely used is the keyboard type electronic code lock, which is mainly used in safes, safes and vaults, and some are used in safe deposit boxes and cash transport vehicles. The keyboard type electronic password is input on the keyboard, which is similar to the telephone call, so it is easy to grasp. The outstanding advantage is that the "password" is the number and character recorded in the mind of the authorized person, which is accurate and reliable, and will not be lost (except forgot). It is difficult to be stolen (unless you disclose it yourself). But the password can't be too simple. It's too easy to be tested by others on the keyboard, or it may be sneaked by bystanders, resulting in insufficient confidentiality. Of course, the password can not be too complicated, too complicated, may be confused, or the input password operation success rate is low, resulting in inconvenient use. Therefore, in order to carry forward the advantages and overcome the weaknesses, keyboard-type electronic passwords are also constantly evolving. For example, the "arbitrary setting password" technology enables the authorized person to set the password according to his own needs or preferences, which is often used frequently; The "password" technology makes the password entered this time automatically changed to the password that should be entered next time. The change rule is not known to others, so it is not afraid of bystanders to peep; the ingenious "keyboard out of order display" technology makes the fixed key on the keyboard The characters displayed each time are not fixed, and the narrow angle of the display can only be seen by the operator. Therefore, even if the observer sees the operation, it is difficult to peek into the password; the "multiple password setting" technology makes the single password not It must be effective and suitable for multi-person decentralization. It is necessary to input more than two sets of passwords to be recognized, which greatly improves the confidentiality. If the order or time period of entering these passwords is limited, the confidentiality can be improved. In the process of entering a password, in order to limit the attempt to test the password, the error code is usually input several times or for a certain period of time, that is, the keyboard is "blocked" and the input operation is no longer accepted. In short, despite the emergence of new types of electronic anti-theft locks, keyboard-type electronic password anti-theft locks are still "old trees sprouting", not only in the market, but also often as an auxiliary input means for other types of electronic anti-theft locks.
Card type electronic anti-theft lock
The electronic anti-theft lock using various "cards" as the key is currently the most active product. No matter the variety of card types, according to the operation mode of the input card, it can be divided into two types: contact card and contactless card. . It is worth noting that due to the requirements of the security industry, magnetic cards with poor reliability and easy to be copied are usually not used. At present, the technology of the contact card is mature, the price is low, and the application is also extensive; the contactless card is concealed and convenient, and it has a tendency to come up later. The large amount of information stored is the advantage of the card. It is not only used as a key, but also can be loaded with a variety of personal information. It is especially suitable for the financial industry to pay attention to the "identification of the body" industry characteristics, and more than one card (such as entry, unlock, storage, payment) Etc.) brings the convenience of the cardholder. The use of such electronic anti-theft locks requires careful storage of the card (ie the key), in particular the loss of authorization to cancel the card as soon as possible.
Biometric anti-theft lock
Some of the innate personality traits of human beings (such as the characteristics of the hands, eyes, and sounds) are almost non-repeatable, and as the "key" is unique (unless forced or hurt), therefore, the use of biometrics as passwords for electronic theft prevention Locks are also particularly suitable for the industry's characteristics of focusing on “identifying the right body†in the financial industry.
Because of the outstanding advantages of this "self-contained, carry-on" "key", this lock quickly passed the initial period of less stable and expensive performance, becoming more and more practical and more and more "features". ", has been widely welcomed by people. Nowadays, biometric technology is developing rapidly. In addition to the limitations of price factors and size factors, the prospect of biometric electronic anti-theft locks in the financial industry is generally optimistic. However, in cases where the confidentiality requirement is extremely high, it is not appropriate to use the biometric electronic anti-theft lock alone, and it is preferable to combine other electronic information as a password.
Since digital, character, graphic images, human biometrics, and time can all be the electronic information of the key, the combined use of this information can make the electronic anti-theft lock highly confidential, such as the defense of the treasury, the need to use the composite information password. The electronic anti-theft lock is such that the thief is "one foot high and one high in the magic." The combination of information can also enable the electronic security lock to expand infinitely, diversify the product, and it is “a thousand choices and self-sufficiency†for the user.
