Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart illustrating a method for detecting a duplicate card according to an embodiment of the present invention, where the method can be executed by a device for detecting a duplicate card, and the device can be implemented in software and/or hardware. The hardware may be an electronic device, optionally a card reader.
Before the technical scheme of the embodiment is introduced, the following application scenarios are briefly introduced. At present, when a user accesses a cell, identity authentication is required, optionally, whether the user can access the cell is verified through a card sent in advance, for example, the method can be applied to a cell, an office building and the like where the user can access the cell by swiping a card, that is, in an application scene where the user needs to access the cell by swiping the card, the technical scheme provided by the embodiment can be adopted to determine whether the card currently used by the user is a duplicate card, and then the technical effect of determining the uniqueness of the card is achieved. Before the card is verified to be the target card, corresponding target data can be stored in the target card, and optionally, a reset code, an initial card swiping record address and authority data when the target card is used for the first time can be stored. The card issuing time, the card issuing machine number and the card issuing serial number can be processed by adopting a snowflake algorithm to obtain the reset code of the target card. In order to improve the security of the target data in the target card, the reset code, the initial card swiping record address and the authority data can be encrypted by adopting an encryption algorithm to obtain ciphertext data corresponding to the target data, and when the card reader reads the data, the ciphertext data can be decrypted by adopting a corresponding decryption algorithm to obtain the target data.
As shown in fig. 1, the method of this embodiment includes:
and S110, reading target data stored in the target chip, wherein the target data comprises a reset code stored in the target chip.
The target chip refers to a chip embedded in the target card and used for storing data. The data stored in the target chip may be taken as the target data. The target data may include a reset code. And determining whether the target card is the card used for the first time according to the value corresponding to the reset code.
Specifically, when a user brings a target card close to the card reader, the card reader can read target data in the target card and acquire a reset code in the target data.
It should be noted that, before each target card is issued by the card issuing system, the target data may be edited in advance, for example, the target data may include authority data, a reset code, and an initial card swiping record address, and the target data is stored in a target chip in the target card. In order to improve the security of the target data, an encryption algorithm may be used to encrypt the target data to obtain ciphertext data corresponding to the target data, and the ciphertext data may be stored in a sector of the target chip. The reset code is uniquely determined, and the issuing card timestamp, the sending machine ID and the issuing serial number corresponding to the card can be processed by adopting a snowflake algorithm to obtain a 64-bit unique reset code corresponding to the target card.
Specifically, when a user approaches or approaches the target card to the card reader, the card reader may read ciphertext data stored in a target chip of the target card, and the card reader may decrypt the ciphertext data by using a corresponding decryption algorithm to obtain decryption data corresponding to the ciphertext data, that is, the target data, and at this time, may obtain a reset code in the target data.
And S120, when the target data is inconsistent with the preset data, determining whether the target data is included in the data stored in the card reader.
The target data at this time mainly refers to a reset code determined when the card issuing system issues a card. The preset data is preset. The preset data may be data corresponding to the reset code, and is used to determine whether the target card is a copy card according to a relationship between the reset code in the target data and the preset data, and optionally, the preset data may be 0. Specifically, whether the target card is the initially used card may be detected first. Optionally, after the target data is acquired, the reset code in the target data may be acquired. When the reset code in the target data is different from the preset data, the target card is not considered to be used for the first time, and whether the data corresponding to the reset code in the target data is stored in the card reader or not can be acquired.
It should be noted that after the target card passes card swiping, the reset code in the target data may be set as preset data, and the 64-bit unique identifier reset code generated when the card issuing system issues the card is stored in the card reader, so that when the target data is read, whether the card is used for the first time is determined according to whether the reset code is stored in the card reader, and then whether the target card is a copied card is determined.
S130, if the target chip exists, determining that the target card to which the target chip belongs is a copy card.
Specifically, when the data stored in the card reader includes a reset code corresponding to the target card, it indicates that the target card has been used by swiping the card or has a card identical to the target card and has been used, and at this time, the target card is not reusable, and the target card may be determined as a copy card.
That is, whether the target card is a copy card may be determined according to whether the card reader stores a reset code corresponding to the target card.
According to the technical scheme of the embodiment of the invention, when the reset code in the target data is read, whether the target card to which the target data belongs is the copy card can be determined according to the relation between the reset code and the preset data, so that the technical problem that whether the target card is the copy card cannot be determined due to the fact that the data stored in each copy card is the initial rolling code in the prior art is solved, and the technical effect of rapidly, conveniently and accurately determining whether the target card is the copy card is realized.
On the basis of the technical scheme, if the stored data does not include the target data, the target data is stored in a cache in the card reader, and the reset code in the target card is updated to the preset data.
It can be understood that if the card reader does not store data corresponding to the reset code in the target card, the target card is considered to be used for the first time, the authority data in the target data can be acquired to perform authority verification, so that after the authority verification is passed, the reset code in the target data is stored in the cache of the card reader, and meanwhile, the reset code in the target card is updated to preset data.
The method has the advantages that whether the target card is used for the first time or not can be quickly determined, and the technical effect that whether the target card is a copy card or not can be further determined based on the copy code is achieved.
Example two
On the basis of the technical scheme, after the target card is determined not to be the copy card based on the copy code, whether the target card is the copy card or not can be determined by further combining the card swiping record address data in the target data, or whether the copy card exists or not can be determined. Fig. 2 is a flowchart illustrating a method for detecting a copy card according to a second embodiment of the present invention. The technical terms that are the same as or corresponding to the above embodiments are not repeated herein.
As shown in fig. 2, the method includes:
s210, reading target data stored in a target chip, wherein the target data comprises a reset code stored in the target chip.
S220, when the target data is consistent with preset data, acquiring current card swiping record address data stored in the target data and historical card swiping record address data stored in the card reader.
It can be understood that when the reset code in the target data is consistent with the preset data, that is, the target card is preliminarily determined to be not a duplicate card according to the reset code, the current card swiping record address data stored in the target data and the historical card swiping record address data stored in the card reader can be acquired.
It should be noted that, when the card is swiped through, the address data recorded by the card may be labeled, optionally, when the card is swiped for the last time, the label of the address data recorded by the card is 1, and when the card is swiped for this time, the label of the address data recorded by the card may be 2. The card-swiping record address stored in the target data can be used as the current card-swiping record address. The historical card swiping record address refers to card swiping record address data which can mark a target card after the target card is read by a card reader.
And S230, determining the target card as a copy card according to the relation between the historical card swiping record address data and the current card swiping record address data.
Specifically, if it is detected that other newly stored historical card swiping record address data besides the current card swiping record address data exist in the historical card swiping record address data, it is considered that other cards read data through the card reader, and the target card can be determined to be a duplicate card; or, if the latest data of the historical card recording address is inconsistent with the current card recording address data, the data is read by other cards through the card reader, and the target card can be determined to be a copy card.
Of course, if it is detected that the historical card swiping record address data does not include data other than the current card swiping record address data, the authority information in the target data is acquired, so as to determine whether the card swiping can pass through according to the authority information.
It is understood that the target data further includes authority data, and the authority data may be access authority and/or floor authority. It should be noted that the permission data may be specifically set according to a specific application scenario, and is not limited herein.
Specifically, when no other card swiping record address data exists in the historical card swiping record address data except the current card swiping record address data, or the latest historical card swiping record address data in the historical card swiping record address data is consistent with the current card swiping record address data, the target card is considered to be not a copy card. At this time, the authority data stored in the target card can be acquired to execute the operation corresponding to the authority data, and optionally, the card is swiped to pass through or the elevator runs to the corresponding floor.
That is, when the authority information coincides with the authority information stored in the card reader, the card is swiped through.
On the basis of the technical scheme, after the card swiping passes, the reset code of the target data in the target chip is updated to preset data, the card swiping record address data in the card reader and the target data is updated to the current card swiping record address data, and whether the target card is a copy card is determined based on the card swiping record address data in the card reader and the card swiping record address data in the target data.
Illustratively, the current card swiping record address data of the target card is 14, the card swiping record address data of the historical card swiping record address data is 14, and the card swiping record address data in the card reader and the target data can be updated to 15 when the card is swiped. Meanwhile, the reset code in the target data may be updated to preset data, and optionally, the preset data is 0.
According to the technical scheme of the embodiment of the invention, when the reset code is determined to be consistent with the preset data, the historical card number recording address data in the card reader and the current card swiping recording address data in the target data can be further obtained, and whether the target card is the copy card or not can be rapidly determined on the basis, so that the technical effects of convenience and accuracy in determining the copy card are improved.
EXAMPLE III
As an alternative embodiment of the foregoing embodiment, fig. 3 is a schematic flow chart illustrating data stored in a target card in advance according to a third embodiment of the present invention. The technical terms that are the same as or corresponding to the above embodiments are not repeated herein.
As shown in fig. 3, the method includes:
and S310, generating a unique reset code ID by adopting a snowflake algorithm.
It should be noted that the new card issued by the card issuing system includes a chip for storing data, and the authority data corresponding to the card may be written in a sector of the chip, and information such as an address initial value, a card reset code, and the like may be recorded by swiping the card.
The snowflake algorithm refers to an algorithm for generating a unique identifier, and aims to solve the problem that when a large amount of data is flooded in a high concurrency period and each resource needs to be identified, the algorithm can be generated.
In this embodiment, the generation of the unique reset code ID by using the snowflake algorithm may be: the method comprises the steps of obtaining a time stamp of a target card issued by a card issuing system, a machine ID of the issued target card and a serial number corresponding to the target card, processing the time stamp, the machine ID and the serial number by adopting a snowflake algorithm to obtain a unique identifier corresponding to the target card, and taking the determined unique identifier as a reset code ID of the target card.
And S320, initializing card swiping record address values.
Specifically, the initializing of the card reading record address value may be to set the card reading record address value to an initial value, and optionally, the initial value may be 0.
And S330, determining the authority data corresponding to the card.
Where rights refer to the extent and degree to which a decision is made on an item.
It should be noted that the permission data corresponding to different application scenarios may be different, for example, if an elevator enters the home after the card is swiped in the application scenario, the permission data may be a floor permission; if the application scene is that the card is swiped to enter and exit the community, the authority data can be entrance guard authority and the like.
Specifically, it can be understood that, according to a specific application scenario, corresponding authority data can be written in the target card, so that the user has corresponding authority when swiping a card to enter and exit.
S340, encrypting the authority data, the card swiping record address value and the reset code ID by adopting an encryption algorithm, and storing a ciphertext obtained through encryption into a sector in the target card.
It should be noted that any encryption algorithm may be used to encrypt the data to obtain a ciphertext corresponding to the data, and the ciphertext is stored in a sector of the target card, so that when the card reader reads the ciphertext, the corresponding decryption algorithm may be used to decrypt the ciphertext to obtain corresponding data, and then the authority of the card and whether the card is a copy card are verified according to the data obtained by decryption.
And encrypting the authority data, the card swiping record address value and the reset code ID to obtain a corresponding ciphertext. Accordingly, the sector may be a storage area for storing the ciphertext.
Specifically, the authority data, the initial value of the card swiping record address and the reset code ID are encrypted by an encryption algorithm to obtain a ciphertext corresponding to the data, and the ciphertext can be stored in a sector of a target chip in a target card.
On the basis, after the card issuing system sends the target card, the target data stored in the target card can be read based on the card reader, and whether the target card is a copy card can be determined based on the target data. As shown in fig. 4, the method includes:
s401, reading the ciphertext in the target card, and decrypting the ciphertext to obtain the reset code, the current card swiping record address and the authority data stored in the target card.
The ciphertext refers to a ciphertext obtained by encrypting the reset code, the card swiping record address value and the authority data. The ciphertext data can be decrypted by adopting a decryption algorithm corresponding to the encryption algorithm to obtain the target data of the target card, namely the reset code, the card swiping record address value and the authority data.
S402, judging whether the reset code is preset data or not, if so, executing S403; if not, go to S404.
The preset data may be a preset reset code, and optionally, the preset data may be 0.
Specifically, if the reset code in the target data is preset data, it indicates that the target card is not used for the first time, and S403 may be executed, that is, the current card swiping record address value in the target data is further obtained to determine whether the target card is a copy card; if the reset code is not the preset data, it indicates that the target card is used for the first time, and may acquire whether the storage area of the card reader stores the reset code corresponding to the card, so as to determine whether the target card is a copy card, i.e., S404 is performed.
S403, acquiring a current card swiping record address, judging whether the historical card swiping record address stored in the card reader comprises the current card swiping record address, and if so, executing S405; if not, go to step S406.
It should be noted that, when the card is swiped through, the card swiping record address may be recorded, for example, when the first card swiping is finished, the card swiping record address may be 1, when the second card swiping is finished, the card swiping record address may be 2, and each time the card swiping is increased, the card swiping record address may be increased by 1, optionally, when the nth card swiping is finished, the card swiping record address may be N.
Wherein, the current card-swiping record address can be the card-swiping record address recorded in the target data. A card reader refers to an instrument that reads data in a target chip. Of course, the card reader may store therein historical swipe record address values corresponding to the target card.
Specifically, when it is determined that the reset code in the target data is consistent with the preset data, it indicates that the target card is not used for the first time, and the card swiping record address in the target data and the historical card swiping record address stored in the card reader can be obtained. And when the historical card swiping record address comprises a card swiping record address except the current card swiping record address, the existence of a copy card corresponding to the target card is indicated. If the card swiping record address except the current card swiping record address is not included in the historical card swiping record address, the card is the target card and is not the copy card.
Illustratively, the current card swiping record address in the target data is 10, the historical card swiping record address is 1-11, and at this time, 11 in addition to 10 is read from the historical card swiping record address, which indicates that the card reader has read a copy card of the card, and at this time, the card with the current card swiping record address of 11 may be used as the target card, and at this time, the used target card is the copy card, and cannot be used any more, that is, S405 is executed. If the current card swiping record in the target data is 10 and the historical card swiping record address is 1-10, that is, the address in the historical card swiping record is consistent with the current card swiping record address, the target card is considered not to be a copy card, and S406 is executed.
S404, judging whether a reset code is stored in the card reader or not, and executing S405 if the reset code is stored in the card reader; if not, go to S407.
It can be understood that, when the reset code is different from the preset data, in order to determine whether the card is used for the first time, the reset code corresponding to the target card stored in the card reader may be acquired, and if the reset code is present, it indicates that the target card is not used for the first time, and the target card may be a copy card; if the reset code corresponding to the target card is not stored in the card reader, the target card is considered to be used for the first time, the reset code can be read, namely 64-bit unique ID generated by adopting a snowflake algorithm is adopted, and the reset code is stored in the card reader to be used for detecting whether the target card is used for the first time.
Of course, after the reset code is stored in the card reader, the reset code in the target card may be set as preset data, so as to improve the technical effect of determining whether the target card is a duplicate card.
S405, determining the target card as a copy card.
That is, the target card may be determined to be a duplicate card based on the above manner.
S406, reading the authority data and confirming the pass.
It can be understood that after the verification of the reset code and the card swiping record address is completed and the target card is determined not to be a copy card, the authority data stored in the target card can be further read, so as to determine whether the card swiping can pass or not according to the read authority data.
Specifically, the authority data in the target data is obtained, and if the authority data is detected to be legal, optionally, if the authority data is of the cell, the card can be swiped to pass through, and otherwise, the card cannot be swiped to pass through.
And S407, storing the reset code into the card reader.
It can be understood that, in order to improve the efficiency of determining whether the target card is a copy card, after determining that the target card is initially used, the reset data in the target card may be stored in the card reader, and the reset code in the target data may be modified into preset data.
And S408, updating the target data in the card reader.
Namely, the reset code in the target data is modified into preset data, and the current card swiping record address in the target data is updated and stored.
According to the technical scheme of the embodiment of the invention, when the reset code in the target data is read, whether the target card to which the target data belongs is the copy card can be determined according to the relation between the reset code and the preset data, so that the technical problem that whether the target card is the copy card cannot be determined due to the fact that the data stored in each copy card is the initial rolling code in the prior art is solved, and the technical effect of rapidly, conveniently and accurately determining whether the target card is the copy card is realized.
