FIG. 1 is a schematic structural diagram of a bar counter system and a cabinet door electronic lock system related to the anti-copy method of the M1 card cabinet door electronic lock of the present invention;
FIG. 2 is a flowchart of a method for preventing copying of an electronic lock of an M1 card cabinet door according to the present invention.
Detailed Description
The present invention is further described in detail with reference to the following specific examples, but the scope of the present invention is not limited by the specific examples, which are defined by the claims. In addition, any modification or change that can be easily made by a person having ordinary skill in the art without departing from the technical solution of the present invention will fall within the scope of the claims of the present invention.
The invention discloses an anti-copy method for an electronic lock of an M1 card cabinet door, which relates to a bar counter system and an electronic lock system of a cabinet door, wherein the bar counter system and the electronic lock system of the cabinet door are shown in figure 1 as an example, and the bar counter system comprises a computer, a card reader and a hand card with an M1 card inside. The cabinet door electronic lock system comprises a cabinet door lock and a hand plate with an M1 card arranged inside,
as shown in fig. 2, the method for preventing the electronic lock of the M1 card cabinet door of the invention comprises the following steps:
firstly, a visitor arrives at a shop and makes a brand at a bar counter;
secondly, when opening cards, a waiter holds the cards and swipes the cards on a card reader, and the card reader reports the card numbers for the financial software to hang up accounts;
the financial software identifies the hand as the newly played hand and sends the information to the card reader through a USB line;
fourthly, after receiving the information, the card reader writes a 'card opening flag bit', namely data, into the hand card; since the M1 card in the hand card is a non-contact radio frequency card, the steps 2-4 can be completed in half a second.
The bather uses the opened hand to punch the card on the cabinet door lock, the cabinet door lock compares whether the password in the card is the same as the password stored in the lock, if so, the bather continues to go downwards, and if not, the bather gives an alarm;
writing a random password into the card and erasing the opening sign in the card immediately if the opening sign bit is recognized after the card is read by the cabinet door lock, storing the password in the lock memory, and reading the card again by the cabinet door lock after the card is written, checking and writing conditions;
seventhly, unlocking the cabinet door lock after confirming that the card writing is successful;
and when the bather subsequently swipes the card to unlock the card, the lock still compares whether the password in the card is the same as the password stored in the lock, but the card does not have a 'opening flag bit', the password is not changed until the hand card is settled and then the card is opened for the next bather to use, and then the password is changed according to the 'opening flag bit' written in the card opening process.
And fourthly, when the card reader of the bar counter plays the cards, writing the 'playing flag bit' into the hand card, reading the data once again to ensure successful writing, reporting the information to financial software on a computer if the writing fails, and prompting a waiter to operate again by the computer.
Writing a random password into the card and erasing a card opening mark in the card immediately after recognizing the card opening mark bit after the cabinet door lock reads the card, then reading data in the card again to ensure that the data is successfully written in, and if the data cannot be written in, not unlocking and prompting a user to swipe the card again by sound; the cabinet door lock rechecks the passwords, the new password and the old password need to be verified at the moment, and if one password is matched, the verification is considered to be successful; then, the task of writing a new password and erasing the 'opening flag bit' is executed.
If the password stored in the lock is different from the password of the bath visitor hand in normal use due to other accidents such as card faults and the like, the waiter can change the passwords in the lock and the card and make the passwords the same by using a method for managing the card matching, which is the conventional operation of the bath cabinet door lock industry.
If a lawbreaker copies the hand after using the cabinet door lock. At this time the password in the copy card is the old password. The bather opens the license again after arriving at the place, and lawless persons can unlock by swiping the copy card before the bather uses the cabinet door lock, but the bather does not deposit the object yet, and the lawless persons can not steal the object, and the normal use of the bather after arriving at the place is not influenced by swiping the copy card to unlock. After the bather uses the cabinet door lock, the lock can write new passwords into the lock again, and the old passwords are invalid. Lawless persons can not unlock by using the copy card.
If lawless persons copy the hand before using the cabinet door lock, the password in the copy card is the old password but has the 'opening mark bit'. If a lawbreaker uses the copy card to unlock the lock after copying the hand cards, the hand cards can not open the door, and the horse feet can be exposed. At the moment, a waiter is called to resynchronize the password, the password can still be changed after the synchronization, and a lawbreaker cannot steal the property. If a lawbreaker swipes the copy card after using the cabinet door, although the card is internally provided with the 'opening mark bit', the password is changed when the bather swipes the card for the first time, the old password cannot be unlocked, and the lawbreaker cannot steal the card.
If a lawbreaker directly copies another person's hand to effect theft. Although the M1 card is a non-contact radio frequency card, the card reading distance of a handheld copying machine is generally not more than 15mm, the time for the copying machine to break the self security key of the M1 card and copy data is generally more than 2 minutes, and the card is required to be reliably read all the time during the breaking period. Therefore, continuous card reading for 2 minutes at a short distance is difficult to realize, and if a lawbreaker can steal the bather card, the bather card can be unlocked directly without copying.
If the method of 'opening the license flag' is adopted, the password in the card is changed only when the bather uses the cabinet door lock for the first time, compared with the scheme of 'changing the password every time of card swiping', the erasing and writing times of data in the card can be reduced, the service life of the M1 card is prolonged, the reaction time of the lock when the user swipes the card to open the door is shortened, and the possibility that the password in the lock and the password in the card is out of synchronization is reduced. Generally, a single person needs to use the cabinet door lock for a plurality of times, and compared with the scheme that the password is changed every time when the user swipes the card, the stability of the method is improved by a plurality of times. The behavior of the lawbreaker copy card cannot influence the normal use of bathers and the normal business of shops under most conditions by adopting the method. If the scheme of changing the password every time the card is swiped is adopted, a lawler can not unlock the normal bather card and disturb the business if the lawler copies one card and tests the swiping card to unlock the lock. The card reader, the cabinet door lock and the M1 card related by the method are not limited to specific models, styles and internal circuit structures, and the method is within the protection scope of the invention. The data transmission between the card reader and financial software, the data transmission between the card reader and the M1 card, the data transmission between the lock and the M1 card, the data storage in the M1 card and the data storage in the lock are not limited to the specific protocol format, the storage format and the hardware interface, and the scheme of the method is within the protection scope of the invention.
While the preferred embodiments of the present invention have been illustrated and described, it will be appreciated by those skilled in the art that various modifications and additions may be made to the specific embodiments described and illustrated, and such modifications and additions are intended to be covered by the scope of the present invention.
