The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with embodiments of the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosed embodiments, as detailed in the appended claims.
Referring to fig. 1, a first aspect of the embodiments of the present disclosure provides a card anti-swipe method, applied to a server, where the method includes the following steps:
step S101, receiving a card swiping request, wherein the card swiping request carries a first dynamic code and a card account number which are generated based on the card swiping times;
step S102, comparing the first dynamic code with a second dynamic code stored in the server;
step S103, if the first dynamic code and the second dynamic code stored in the server do not meet preset similar conditions, rejecting the card swiping request and locking the card account.
In this embodiment of the present disclosure, in step S101, the server may obtain the first dynamic code and the card account number of the card based on the card swiping request; in step S102, the first dynamic code is compared with the second dynamic code stored in the server, so as to determine whether the card is a legal card in time; in step S103, if the first dynamic code and the second dynamic code stored in the server do not satisfy the preset similar condition, the card swiping request is rejected and the card account is locked, and if the first dynamic code and the second dynamic code stored in the server do not satisfy the similar condition due to illegal card swiping, the card swiping request is rejected and the card account is locked, so that the card is prevented from being illegally swiped, the security of the card is improved, and the card account is directly locked by the server, so that the server can easily manage the card.
Referring to fig. 2, in the embodiment of the present disclosure, the card swipe protection method further includes:
step S1041, if the first dynamic code and the second dynamic code satisfy the preset similar condition, responding to the card swiping request;
step S1042, updating the second dynamic code stored in the server according to the total card swiping times of the card account;
and step S1043, sending the second dynamic code to the card sending the card swiping request.
In the embodiment of the present disclosure, after step S1041, step S1042 indicates that the server may update the second dynamic code according to the total card swiping time, and only after the card swiping is successful, the second dynamic code is updated, and step S1042 is performed, so that the correctness of the card swiping time record may be ensured.
In an embodiment of the present disclosure, the first dynamic code and the second dynamic code each include: a first portion and a second portion; the second part is dynamically generated according to the card swiping times;
the first dynamic code and the second dynamic code stored in the server do not meet preset similar conditions, and the method comprises the following steps:
and if the first part of the first dynamic code is the same as the first part of the second dynamic code, the difference value between the second part of the first dynamic code and the second part of the second dynamic code is larger than a preset value.
In the embodiment of the present disclosure, the first part is not dynamically generated according to the number of times of card swiping, but is a fixed number segment, and the first dynamic code and the second dynamic code are equally divided into two parts, so that when comparing the first dynamic code and the second dynamic code, two comparisons can be performed, the comparison steps are increased, and the possibility of the card being safely used is further improved.

step S2051, receiving a card locking instruction sent when the first dynamic code and the second dynamic code stored in the server do not satisfy a preset similar condition;
and step S2052, locking the card according to the card locking instruction.
In the disclosed embodiment, the manner of locking the card includes but is not limited to:
the card swiping machine writes a locking mark into the card, and after the card is locked in this way, when the card touches the card swiping machine, the card swiping machine only needs to directly read the locking mark in the card, and does not need to inquire whether the card account number is locked or not from a server. The work flow of the card swiping machine can be simplified.
In the disclosed embodiment, the card may not be locked, and whenever a sensor in the swipe machine senses contact of the card, a server is queried whether the card account number is locked.
In an embodiment of the present disclosure, the first dynamic code and the second dynamic code stored by the server each include: a first portion and a second portion;
the method further comprises the following steps:

and writing the updated second dynamic code into the card.
In the embodiment of the disclosure, the card swiping machine writes the updated second dynamic code into the card, and after the card swiping operation is successfully executed, the updated second dynamic code is written into the first dynamic code in the card, so that the correctness of the card swiping time record can be ensured.
In this embodiment of the disclosure, after responding to the card swiping request, the server may update the first dynamic code stored in the second dynamic code according to the total card swiping times of the card account, and write the second dynamic code into the first dynamic code in the card.
In this embodiment of the present disclosure, before sending the card swiping request, the card swiping machine may update the first dynamic code, for example, add 1 to the first dynamic code, and send the card swiping request carrying the first dynamic code to the server, where at this time, the updated first dynamic code is greater than the second dynamic code stored in the server by 1, and the server compares whether the values of the updated first dynamic code minus 1 and the second dynamic code stored in the server are consistent.
In this embodiment, the card swiping machine may update the first dynamic code before sending the card swiping request, for example, add 1 to the first dynamic code, and the server also updates the second dynamic code synchronously when receiving the card swiping request, for example, add 1 to the second dynamic code, and then compare the updated first dynamic code with the updated second dynamic code.
In the embodiments of the present disclosure, regarding the updating of the first dynamic code, the updating of the second dynamic code, and the comparison of the first dynamic code and the second dynamic code, the above-described embodiments may be arbitrarily combined on the basis of compliance logic, and the embodiments of the present disclosure are not limited thereto.
In the embodiment of the disclosure, a mode of comparing a first dynamic code with a second dynamic code stored in a server is adopted, if the first dynamic code and the second dynamic code stored in the server do not meet preset similar conditions, the card swiping request is rejected and the card account number is locked, so that card swiping requests of a legal card and an illegal card corresponding to the card account number are rejected, at the moment, the card can be prevented from being illegally swiped, the safety of the card is improved, and the server directly locks the card account number at a server side, so that the management of the card is easy; after the server refuses the card swiping request and locks the card account number, the difference value of the comparison between the first dynamic code and the second dynamic code stored by the server represents the transaction number of the stolen card swiping, so that the transaction number of the stolen card swiping can be clearly known.
The following examples are provided in connection with the above embodiments:
example 1: example 1 provides a card swipe prevention method, the method comprising:
data initialization: the data initialization comprises: campus IC card initialization and database data initialization.
The campus IC card initialization comprises the following steps: writing an IC card unique card number (hereinafter, referred to as card sum) and an initial dynamic code 10000000001 (hereinafter, referred to as sign1) into the campus IC card;
the database initialization includes: the database writes the initialization dynamic code 10000000001 (hereinafter referred to as sign2) and the abnormal dynamic code 0 (hereinafter referred to as sign 3).
Normal card swiping of a legal card:
the logic of normal card swiping of the legal card is as follows: a legal user holds a legal card and normally swipes the card to a consumer machine, the consumer machine writes a new sign1 value into the card as original sing1+1 after acquiring the card cardNum and sign1 of the legal card, the consumer machine transmits the new sign1 value to a database server through a network, compares the sign1 (front 3 bits) with the sign2 (front 3 bits) number segment value in the database, subtracts 1 from the sign1 (rear 8 bits) by the number of strokes of 1 and sign2 (rear 8 bits) after the number segments are consistent, and swipes the card and consumes successfully through verification logic after the number segments are consistent.
Locking legal card and illegal card:
at some point, one (or more) illegal cards are copied from a legal card (e.g., sign1 ═ 10000000002), and both cardNum and sign1 of the illegal card are identical to the legal card. Then the illegal card is successfully consumed on a consumer machine one or more times (example 5 times), at this time, sign1 of the illegal card is 10000000007, sign2 in a database is 10000000007, and sign3 is 0; a legal user holds a legal card (sign1 is 10000000002), new sign1 is 10000000003 written in the consumer for consumption, the card number is compared with sign2 in a database, the system judges that the number segments 100 are consistent and the transaction number is inconsistent, illegal card embezzlement wind control is triggered, the card number cardNum is locked and cannot be traded, 5 transaction records of the transaction number between 1 and 1 minus sign1 and sign2 are obtained, the system judges that the 5 transaction records are illegal transactions, and the legal card and all illegal cards cannot be normally used at the moment.
Unlocking the card:
and after the legal user finds that the legal card is locked and cannot transact, the legal user holds the legal card to the card service center for unlocking. The card service center administrator writes a new number segment (example 101) + the original transaction number into the card to form a new sign1, writes the sign2 value in the database into the sign3, updates the new sign1 to the singing 2, and modifies the state of the card to be normal. At this time, sign1 of the legal card is 10100000003, sign2 of the database is 10100000003, sign3 is 10000000003, and sign1 of the illegal card is 10000000007.
The illegal card is locked continuously:
after the legal user holds the legal card to unlock, sign1 of the legal card can pass the verification of normal consumption. The number segment 100 of the illegal card is inconsistent with the number segment 101 in the database, and the wind control is triggered to directly prompt that the illegal card cannot consume normally. The frequent card swiping behavior of the illegal card can not cause the locking of the legal card.
As shown in fig. 5, the card usage flow is as follows:
student card swiping (online consumption);
the consumer machine obtains card information (card number/stroke number), if the network connection is abnormal, the card cannot be written;
if the network connection is normal, the consumption machine writes a new stroke number (the stroke number is added with 1) into the card, and if the new stroke number fails to be written, the consumption machine prompts: please swipe the card again;
if the new stroke number is successfully written, sending a consumption request to a server;
the server processes the consumption information, and if the consumption stroke number is detected to be abnormal, the server processes the consumption information;
if the number of consumption strokes is normal, the server returns a consumption result, if the network is overtime, the consumption machine does not display the consumption result, and then the last order with successful consumption can be inquired through a page turning up and down button on the machine;
if the network is not overtime, the consumption machine successfully receives the consumption result;
and the consumer machine displays the consumption result.
In an example of the present disclosure: the number segment with fixed number of bits + the number of card swiping times with fixed or non-fixed number of bits are used as dynamic codes (the length of the number segment and the length of the number of card swiping times can be expanded according to business requirements), for example, the three-bit number segment 100+ the fixed 8-bit number of card swiping times 00000001 are combined into the dynamic code 10000000001. Under the condition that the normally used card is not copied, the database server records two dynamic codes, namely an initial dynamic code 10000000001 (sign 2 for short) and an abnormal dynamic code 0 (sign 3 for short). Swiping a card on a consumer machine, writing a new dynamic code 10000000002 (rule: number field is unchanged, card swiping times +1, sign1 for short) into the campus IC card by the consumer machine, simultaneously transmitting the card number and the sign1 to a database server, and judging whether the stolen swiping and the number of the stolen swiping strokes and the fund information exist by the database server through checking the values of the sign1, the sign2 and the sign 3.
