With the progress of society, science and technology, and culture, the security of mechanical locks has become increasingly inadequate to meet the needs of the people. Moreover, to some extent, the strength of security measures is actually related to identity and status. Electronic smart locks (Including password locks, card locks, fingerprint locks, iris locks, etc.) As the advantages of the new generation of identification technologies become more obvious, it will gradually replace the mechanical locks as the new protagonist of the lock industry.
Electronic anti-theft lock type 1, remote control electronic anti-theft lock
At present, common remote-controlled electronic anti-theft locks mainly include light remote control and radio remote control. Light remote control is divided into infrared remote control and visible light remote control. Optical remote control uses narrow-angle light transmission password. The advantage is that the amount of transmitted information can be very large, extremely fast, and the human eye can not recognize it, and it cannot be in the light path (operator and Electronic security lock body) is captured by the instrument to try to copy the signal, so confidentiality is extremely high. The advantage of radio remote control is that the amount of information transmitted can be large, fast, and can not be recognized by the human eye. However, the transmitted signal disperses space and is easily captured by the instrument. Therefore, it is appropriate to use the “changed passwordâ€, such as the so-called “hop codeâ€. "Rolling code" (all are random changes without obvious laws), so that even if the captured signal at the time is not used, the value of copying is not used. The use of remote electronic anti-theft locks requires careful storage of the remote control (ie, the key), and for some applications, this key is a little larger and may require the use of a specific battery.
Second, the keyboard type electronic code lock
Judging from the current level of technology and market acceptance, the most widely used keyboard-type electronic combination locks are mainly used in safes, safes, and vaults, and some are used in safe deposit boxes and armored cars. The keyboard type electronic password is entered on the keyboard, which is similar to that of the telephone, so it is easy to grasp. The outstanding advantage is that the “password†is the number and the character recorded in the authorized person's head. It is accurate and reliable and will not be lost (except forgotten). It is hard to be stolen (unless it is leaked). However, passwords cannot be too simple. They are too easy to be tested by others on the keyboard, or they may be viewed by onlookers, causing lack of confidentiality. Of course, the password can not be too complex, too complicated and may be confused, or the success rate of entering the password operation is low, resulting in inconvenient use. Therefore, in order to develop advantages and overcome weaknesses, keyboard-type electronic passwords are also constantly evolving. For example, “arbitrarily set passwords†technology allows authorized persons to set passwords according to their own needs or preferences, and often use new ones; "Password" technology allows the password entered this time will be automatically changed to the next password should be entered, the law of change is not known to others, and therefore not afraid of onlookers prying; unique "keyboard out of order display" technology makes the keyboard fixed keys The characters displayed each time are not fixed, and the displayed narrow angle can only be seen by the operator. Therefore, it is difficult for a bystander to see the password even if he/she sees the operation. The “multiple password setting†technology makes the single password not It must be effective and suitable for decentralized use of multiple people. It requires the input of more than two sets of passwords to be recognized and greatly enhances confidentiality. If the order or time zone of these passwords is restricted, confidentiality can be improved. In the process of inputting the password, in order to limit attempts to test the password, an error code is often input for several times or incorrectly entered in a certain amount of time, ie, the keyboard is “blocked†and no longer accepts input operations. In short, despite the emergence of new electronic anti-theft locks, keyboard-type electronic code anti-theft locks are still “old trees sproutingâ€, not only occupying a mainstream position in the market, but also often used as auxiliary input means for other types of electronic anti-theft locks.
Third, card type electronic anti-theft lock
Electronic anti-theft locks using various “cards†as keys are currently the most active products. Regardless of the variety of card types, according to the input card operation methods, they can be divided into contact cards and contactless cards. . It is worth noting that due to the requirements of the security industry, magnetic cards with poor reliability and easy to be copied are generally not allowed. At present, the contact card technology is mature, the price is low, and the application is also more extensive; the use of contactless cards is hidden and convenient, and there are great potentials to come from behind. The large amount of stored information is the card's advantage. It not only serves as a key, but also contains a number of personal information. It is particularly suitable for the financial industry's emphasis on the industry characteristics of "examination and justification," and it is also versatile with one card (such as entry, unlock, storage, and payment). Etc.) Bring cardholder convenience. The use of such electronic anti-theft locks requires careful storage of the card (ie, the key), and in particular the loss of the authorization to cancel the card as soon as possible.
IV. Biometric anti-theft lock
Some of the person's inherent personality traits (such as the features of the hands, eyes, and voice) are almost non-repeatable. The "key" is the only one (unless it is persecuted or hurt). Therefore, the use of biometrics as the password for electronic theft prevention The lock is also particularly suitable for the financial industry to focus on the industry characteristics of "exact proof". Because of the outstanding advantages of this "key", which is self-born and portable, this type of lock quickly passed through the initial period of unsteady performance and high price, becoming more and more practical and increasingly "characteristic." "It has been generally welcomed by people. Nowadays, the development of biometric technology is rapid. In addition to price factors and size and volume factors, the popularity of electronic anti-theft locks in the financial industry is generally favored. However, it is not advisable to use a biometric electronic anti-theft lock when it is required to have high confidentiality. It is better to combine other electronic information as a password.
Since digital, characters, graphic images, human biometrics, and time can all be key electronic information, the combination of these information can make electronic anti-theft locks highly confidential. Electronic anti-theft lock, so that is for the thieves, "a high foot, a high degree of magic". Combined use of information can also enable electronic anti-theft lock to obtain the possibility of inexhaustible expansion, so that the product diversification, for the user is "thousands of choice, self-serving."
V. Electronic anti-theft locks used in the financial industry
The electronic anti-theft lock applied to the financial industry, its fundamental role is "authorization", that is "authorized" personnel can access money and things. Broadly speaking, the "authorization" of the financial industry mainly includes the following three levels of content:
· The granting of custodial rights, such as the use of safes, safes and safes;
· Grant access rights, such as access to the treasury, armored cars and storage room;
· Granting circulation rights, such as automatic deposit and withdrawal.
At present, the application of electronic anti-theft locks in the financial industry mainly focuses on the first two levels.
Sixth, electronic anti-theft lock development trend
Of course, the above-mentioned authorization technology must be superbly performed by sophisticated “locks†as carrying structural components to achieve the functions of opening and closing, as well as taking over physical protection, resisting or delaying destruction as much as possible, and allowing electronic anti-theft locks. Soft and hard do not eat." Under normal circumstances, the key to anti-theft locks is the strength of the lock shell and the locked parts (such as the retractable bolts or lock bolts, the lock box lock plate, and the electromagnetic components directly locked by electromagnetic force, etc.) (should be sufficient Mechanical strength and rigidity, able to withstand certain values, static pressure and impact forces in certain directions, and moments), lock type (tolerant to certain modes and tool functions), and clearances (to prevent mechanical and electronic methods The lock is internally opened and the layout (the components and circuits that are directly related to the opening of the lock are placed under the protection of the housing and are not easily identified).
The inevitable way to improve the protection capabilities of electronic anti-theft locks is the alarm. In many places in the financial industry, people are on duty, have television monitoring, have an alarm function, and can combine physical and human defense. The premise of the alarm is the detection function. According to the location and protection requirements of the electronic anti-theft lock, various detection methods can be selected. In China's urban financial industry, the realization of networked alarms has become a basic requirement for all financial networks.
According to the practical experience at home and abroad, it is necessary for the financial industry to implement a safety risk prevention level. That is, based on the performance of the anti-theft alarm equipment used, the installation layout, and the personnel's duty status, the protective ability of the protected object or area can be evaluated and the risk can be obtained. Grade, among them, the performance of electronic anti-theft lock is very important.
