Technical Field

The invention belongs to the field of biological electronic locks, and particularly relates to an off-line biological lock, a coded lock system, an opening and closing method and a storage medium.

Background

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art or the prior art.

In high security requirement scenes, such as a vault, a firearm warehouse, an automatic teller machine, a safe, a confidential document cabinet and the like, the dynamic coded lock is a necessary security measure. The dynamic password lock is a lock which is unlocked by sending a dynamic password from a background server.

As shown in fig. 1, a current bio-lock (dynamic combination lock using a result of matching biometric features as an unlocking key) system generally comprises three major parts, namely a lock disc, a lock body, and an electronic lock management system (hereinafter abbreviated as ELMS). In the above system, the lock disk has a biometric collector (e.g., fingerprint, finger vein) for dynamically collecting the biometric of the person who unlocks the lock. The unlocking mode of the lockset is that the biological characteristics acquired in real time in a dynamic way are matched and compared with the biological characteristics collected by registration, and the matching result is used as a precondition for unlocking permission to judge, so that the unlocking and locking of the lockset are realized. Because the human biological characteristics have unique characteristics, the lockset has higher security level than the traditional dynamic coded lock. However, the opening and closing of the lock involves uploading (or sending) communication of biological characteristics, so the lock adopts the design scheme of the opening and closing lock of an online lock (the lock and the server ELMS must communicate through a network). In a specific application example, for example, in order to ensure the security of business transaction, the ATM machine uses a bank private network for communication, but the bank usually outsources cash services such as cash adding and clearing of the ATM to the CIT company, that is, the password lock installed on the ATM is usually unlocked and locked by the CIT company (i.e., the password lock belongs to the CIT company). The bank usually does not authorize the CIT company to use the bank's private network for free-trade security, which causes the above-mentioned on-line unlocking and locking scheme to have the following problems in the real market promotion:

(1) the CIT company cannot obtain the bank authorization to use the special network and the bank server of the bank, and the CIT company is faced with the situation that no network is available or the special network of the CIT company needs to be laid at a high cost, so that the CIT company cannot consider the coded lock of the online lock opening and closing scheme at all;

(2) the bank authorizes the bank's private network and bank server for compensation, which means that the CIT company needs to spend huge rental fee every year, and the CIT company is concerned with the operation cost, and the interest of using the password lock of the online locking and unlocking scheme is greatly reduced or even not considered.
