The electronic card copy prevention device 200 comprises an authorization module 201, an acquisition module 202, a recording module 203, a disabling module 204, a judgment module 205 and a write-back module 206.
The authorization module 201 is configured to write a unique identification code and a card reading time stamp into the electronic card 30. Before issuing the electronic card 30 to the user, the card issuing entity (the stock company, the developer, etc.) authorizes the electronic card 30 and writes the unique identification code and the card reading number mark into the electronic card 30. The unique identification code corresponds to only one card, and the memory 101 stores the unique identification code of each authorized electronic card 30. The electronic card 30 has a storage area, which may include an area a and an area B, and the specific way of writing the unique identification code and the card reading number mark into the electronic card 30 may be: and writing the unique identification code into the area A, and writing the card reading time mark into the area B, wherein the card reading time mark can be a natural number, a letter and the like, or a combination of the natural number and the letter, and the initial value of the card reading time mark is preferably '0'.
The obtaining module 202 is configured to read card swiping data of the electronic card 30 through the card reading device 20, where the card swiping data includes the unique identification code and the card reading time stamp. The card swiping data may also include identity information of the user, such as a phone number, a house number, and the like.

The write-back module 206 is configured to write the updated card reading times mark into the electronic card 30. The obtaining module 202 obtains the unique identification code and the card reading time stamp of the electronic card 30, and then updates the card reading time stamp, in this embodiment, the card reading time stamp adopts an arabic number starting from 0, and the card reading time stamp is updated by adding 1 to the card reading time stamp obtained each time. For example, when the acquired number of times of reading is marked as "0", the number is updated to "1"; when the acquired number of times of reading is "5", the acquired number is updated to "6", and the number of times of reading is written in the B area of the storage area of the electronic card 30 by the card reading device 20, such as "1" or "6".
The recording module 203 is further configured to record the updated card reading data, and record "1" if the updated card reading frequency is marked as "1", and store the "1" in the memory 101.
The disabling module 204 is configured to disable the permission of the electronic card 30 if the reading time flag is repeated with the reading time flag recorded in the history.
The determining module 205 is configured to determine whether the number of times that the card reading number flag is repeated with the card reading number flag of the history record reaches a preset value. After each time the electronic card 30 is swiped, the recording module 203 records the card reading time flag stored in the card, and the card reading time flag stored in the electronic card 30 is updated after each time the card is swiped. After the electronic card 30 is swiped for multiple times, the memory of the management server 10 stores multiple card reading time marks, and if the multiple card reading time marks are repeated and the number of the repeated times reaches a preset value, if the number of the repeated card reading time marks is 2 or 3, the disabling module 204 disables the permission of the electronic card 30. The principle of the determination method of the management server 10 is described in detail below.
Fig. 4 is a schematic diagram of the management server 10 according to the first embodiment of the present invention. The electronic card 30 can be divided into an authorization card 301 and a copy card 302, the authorization card 301 is the electronic card 30 authorized by the management server 10 and written with the unique identification code and the card reading time mark, and the copy card 302 is the electronic card 30 copied by the authorization card 301 and having the same unique identification code and the card reading time mark stored in the authorization card 301. The data information contained in the authorization card 301 and the copy card 302 is the same, and the card reading count flag in the copy card 302 is the same as the card reading count flag stored when the authorization card 301 is copied.
In this embodiment, the copy card 302 is obtained by copying when the number of times of reading the card stored in the authorization card 301 is marked as "2", and the two cards have the same unique identification code. The initial card reading time mark of the authorization card 301 is "0", and when the card is swiped for the first time, the management server 10 stores the card reading time mark "0" and sends the updated card reading time mark "1" to the authorization card 301; the management server 10 stores the card reading number flag "1" when swiping the card for the second time, and transmits the updated card reading number flag "2" to the authorization card 301. At this time, the authorization card 301 is copied to obtain a copy card 302.
When the authorized card 301 swipes the card for the fourth time, the authorized card 301 obtains the card reading number flag "4" written back by the management server 10, and the card reading number flag stored in the management server 10 includes: "0", "1", "2", "3". At this time, if the copy card 302 swipes the card on the card reading device 20, and after twice swipes the card, the reading number flag in the copy card 302 is updated to "4", the reading number flag acquired by the management server 10 when the copy card 302 swipes the card twice is "2" or "3", and the two reading number flags are already stored in the memory 101, each time is determined to be repeated. If the preset value of the number of repetitions is 2, the disabling module 204 disables the permission of the copy card 302. It should be noted that since copy card 302 is identical to authorization card 301 in copying, electronic card 30 disabled by disabling module 204 may be either copy card 302 or authorization card 301.
Second embodiment
