Remote-controlled electronic anti-theft lock

At present, the common remote-control electronic anti-theft locks mainly include optical remote control and radio remote control. Optical remote control is divided into infrared remote control and visible light remote control. Optical remote control uses a narrow angle of light to transmit the password. The advantage is that the amount of information transmitted can be large, the speed is very fast, the human eye cannot recognize it, and it cannot be on the light path (operator and Between the electronic anti-theft locks) to capture the signal with the instrument to try to copy, so the confidentiality is extremely high. The advantage of radio remote control is that the amount of transmitted information can be large, fast, and human eyes cannot recognize it, but the transmitted signal diffuses in space and is easy to be captured by the instrument, so it is suitable to use "changing passwords", such as so-called "code hopping", "Rolling code" (all are randomly changing without obvious rules), so that even if the signal at the time is captured, there is no use and copy value. Using a remote-type electronic anti-theft lock requires careful storage of the remote control (ie, key), and for some applications, this key is a bit larger and may require the use of specific batteries.

Keyboard type electronic combination lock

From the current technical level and market recognition, the most widely used is the keyboard-type electronic combination lock. This product is mainly used in safes, safes and vaults, and some of them are used in safe deposit boxes and cash transport vehicles. The keyboard-type electronic password is entered on the keyboard, which is similar to making a phone call, so it is easy to master. Its outstanding advantage is that the "password" is the numbers and characters recorded in the authorized person's brain, which is accurate and reliable, and will not be lost (except forgotten) , Difficult to be stolen (unless leaked by yourself). However, the password cannot be too simple. If it is too simple, it can be easily tested by others on the keyboard, or it may be peeped by bystanders, resulting in insufficient confidentiality. Of course, the password can't be too complicated. If it's too complicated, you may be confused, or the success rate of entering the password is low, which makes it inconvenient to use. Therefore, in order to carry forward the advantages and overcome the weaknesses, keyboard-type electronic passwords are also constantly evolving. For example, the “arbitrarily set password” technology allows authorized persons to set passwords according to their own needs or preferences. "Password" technology makes the password entered this time automatically change 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 snoop; the unique "keyboard disorder display" technology makes the fixed keys on the keyboard The characters displayed each time are not fixed, and the narrow angle displayed can only be seen by the operator, so it is difficult to spy on the password even if the spectator sees the operation; the "multiple password setting" technology makes a single group of passwords not It must be effective and suitable for multi-person decentralization. It needs to enter more than two sets of passwords to be recognized, which greatly improves the confidentiality. If the order or time section of entering these passwords is limited, the confidentiality can also be improved. In the process of entering the password, in order to limit the attempts to try the password, usually the wrong code is entered several times or incorrectly entered within a certain time, that is, the keyboard is "blocked" and no longer accepts the input operation. In short, despite the emergence of new types of electronic anti-theft locks, keyboard-type electronic password anti-theft locks are still "newly sprouting", not only in the mainstream position in the market, but also as an auxiliary input means for other types of electronic anti-theft locks.

Card type electronic anti-theft lock

Electronic anti-theft locks that use various "cards" as keys are currently the most active products. No matter how many types of cards are, according to the operation mode of the input card, they can be divided into contact card and contactless card. . It is worth noting that due to the requirements of the security industry, it is generally not allowed to use magnetic cards with poor reliability and easy to be copied. At present, the technology of contact cards is mature, the price is relatively low, and the application is also extensive; the use of contactless cards is concealed and convenient, and there is a tendency that it will later prevail. The large amount of stored information is the advantage of the card. It is not only used as a key, but also can load a variety of personal information. It is especially suitable for the industry characteristics that the financial industry pays attention to "identify the body", and it is multi-purpose for one card (such as entry, unlocking, storage, payment Etc.) brings cardholder convenience. The use of this type of electronic anti-theft lock requires careful storage of the card (that is, the key), especially if you lose the authorization of the card as soon as possible.

Biometric anti-theft lock

Some innate personal characteristics of humans (such as the characteristics of hands, eyes, and sounds) are almost unrepeatable, and they are unique as "keys" (unless they are forced or injured). Therefore, electronic anti-theft using biological characteristics as passwords Locks are also particularly suitable for the characteristics of the financial industry that focus on "identifying the right body".

Due to the outstanding advantages of this "self-growing, carry-on" "key", this lock quickly passed the initial stage of unstable performance and expensive, becoming more and more practical and more and more "features" ", Is generally welcomed by people. Nowadays, biometric technology is developing rapidly. In addition to the price factor and size and volume factors that still limit the popularity, the prospect of biometric electronic anti-theft locks in the financial industry is generally optimistic. However, in the case of extremely high confidentiality, it is not suitable to use the biometric electronic anti-theft lock alone, it is best to combine other electronic information as a password.

Elements such as numbers, characters, graphic images, human biometrics, and time can all become electronic information of the key. The combined use of these information can enable the electronic anti-theft lock to obtain a high degree of confidentiality. For example, to prevent a strong vault, it is necessary to use a compound information password. Electronic anti-theft locks, so to the thieves, "the road is one foot tall, the magic is one foot tall." The combined use information can also enable the infinite expansion of the electronic anti-theft lock, and diversify the products. For users, it is "a thousand choices and a place for themselves".

The development trend of electronic anti-theft lock

Electronic anti-theft locks are used in the financial industry, and their fundamental role is to "authorize", that is, those who are "authorized" can access money and things. Broadly speaking, the "authorization" of the financial industry mainly includes the following three levels of content: 1. Grant custody rights, such as the use of safe deposit boxes, safes, and safes; 2. Grant access rights, such as access to the vaults, cash transport vehicles, and custody Room; 3. Grant circulation rights, such as automatic deposit and withdrawal. At present, the application of electronic anti-theft locks in the financial industry is mainly concentrated on the first two levels. The following will introduce several electronic anti-theft locks used in the financial industry and their technical development direction.

Of course, no matter how superb the authorization technology mentioned above is, a sophisticated "lock" must be used as a load-bearing structural component to realize the function of opening and closing, and it must bear the physical protection function to resist or delay the destruction as much as possible, so that the electronic anti-theft lock " Don't eat soft or hard. " Under normal circumstances, the key to the anti-theft of locks is the strength of the lock body shell and the locked components (such as telescopic bolts or bolts, lock box lock plates, and electromagnetic components that are directly locked by electromagnetic force, etc.) (there should be sufficient Mechanical strength and stiffness, can withstand a certain value, static pressure and impact force and moment in a certain direction, lock type (can withstand the action of certain methods and tools), fit clearance (prevent the use of mechanical, electronic methods to penetrate The lock is opened inside) and the layout (the weak parts and circuits directly 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 capacity of electronic anti-theft locks is to call the police. Many people in the financial industry are on duty, have TV monitoring, and have an alarm function, which can integrate both physical and human protection. The premise of the alarm is to have a detection function. According to the use place and protection requirements of the electronic anti-theft lock, a variety of detection methods can be selected. In China's urban financial industry, the realization of online alarms has become a basic requirement for all financial outlets.

According to the domestic and international practical experience, it is necessary for the financial industry to implement a security risk level, that is, according to the performance of the anti-theft alarm equipment used, the installation layout and the personnel on duty status, etc., it is possible to evaluate the protective ability of the protected object or area and obtain the risk Level, in which the performance of electronic anti-theft locks is critical.
