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.
The development trend of electronic anti-theft lock
The electronic anti-theft lock is used in the financial industry. Its fundamental role is to “authorizeâ€, that is, the “authorized†talent can access money and goods. Broadly speaking, the “authorization†of the financial industry mainly includes the following three levels of content: 1. Granting custody rights, such as the use of safe deposit boxes, safes and safes; 2. Granting access rights, such as access to treasury, cash transport vehicles and safekeeping Room; 3, grant circulation rights, such as automatic deposit and withdrawal. At present, the application of electronic security locks in the financial industry is mainly concentrated on the first two levels. The following are some of the electronic anti-theft locks that are used in the financial industry and their technological development.
Of course, the above-mentioned authorization technology is superb, and it must be carried out by a sophisticated "lock" to carry the structural components, to achieve the function of opening and blocking, and to undertake the physical protection, resist or delay the destruction behavior, and let the electronic anti-theft lock " Soft and hard, don't eat." Under normal circumstances, the key to the anti-theft of the lock is the strength of the lock body, the locked parts (such as the telescopic bolt or lock bolt, the lock box lock plate and the electromagnetic components directly locked by electromagnetic force) (should be sufficient) Mechanical strength and stiffness, capable of withstanding certain values, static and impact forces and moments in a certain direction), locking type (can withstand the effects of certain methods and tools), matching clearance (preventing mechanical and electronic methods) The inside of the lock is opened and the layout (the parts and circuits that are weakly related to the opening of the lock are placed under the protection of the housing and are not easily recognized).
The inevitable way to improve the protection capability of electronic anti-theft locks is to alarm. In many places in the financial industry, there are people on duty, TV monitoring, and alarm function, which can combine physical defense and human defense. The premise of the alarm is that it has a detection function. According to the use place and protection requirements of the electronic anti-theft lock, a variety of detection means can be selected. In China's urban finance industry, the realization of networked alarms has become a basic requirement for financial outlets.
According to the practical experience at home and abroad, it is necessary for the financial industry to implement the safety precautionary risk level, that is, according to the performance, installation layout and personnel duty status of the anti-theft alarm equipment used, it is possible to evaluate the protection ability of the protected object or the area and obtain the risk. Level, where the performance of the electronic anti-theft lock is crucial.
