Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a schematic flow chart of a method for detecting a duplicate card according to an embodiment of the present invention, where the method can be performed 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 scenario is first introduced. At present, when a user accesses a cell, identity verification is required, and optionally, whether the user can access the cell or not 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 accesses by swiping a card, namely, the technical scheme provided by the embodiment can be adopted to determine whether the card currently used by the user is a copy card as long as the user accesses by swiping the card, so that the technical effect of card uniqueness is determined. Before verifying whether the card is a 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. And processing the card issuing time, the card issuing machine number and the card issuing serial number 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, an encryption algorithm can be adopted to encrypt the reset code, the initial card swiping record address and the authority data to obtain ciphertext data corresponding to the target data, so that when the card reader reads the data, a corresponding decryption algorithm can be adopted to decrypt the ciphertext data to obtain the target data.
As shown in fig. 1, the method of this embodiment includes:
s110, reading target data stored in a 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 for storing data. The data stored in the target chip may be regarded as target data. The target data may include a reset code therein. And determining whether the target card is the card for initial use according to the value corresponding to the reset code.
Specifically, when the user approaches the target card to the card reader, the card reader can read the target data in the target card and acquire the reset code in the target data.
It should be noted that, before the card issuing system issues each target card, 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 store the ciphertext data in a sector of the target chip. The reset code is uniquely determined, and a snowflake algorithm can be adopted to process the issued card time stamp, the sending machine ID and the issued serial number corresponding to the card, so as to obtain a 64-bit unique reset code corresponding to the target card.
Specifically, when the user approaches or approaches the target card to the card reader, the card reader can read ciphertext data stored in the target chip in the target card, and the card reader can decrypt the ciphertext data by adopting a corresponding decryption algorithm to obtain decrypted data corresponding to the ciphertext data, namely the target data, and can acquire a reset code in the target data.
And S120, when the target data are inconsistent with the preset data, determining whether the stored data in the card reader comprise the target data or not.
Wherein, the target data at this time mainly refers to the reset code determined when the card issuing system issues the card. The preset data is preset. The preset data may be data corresponding to a reset code, and is used for determining 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, it is possible to detect whether the target card is an initially used card. Optionally, after the target data is acquired, a 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 considered not 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.
After the target card swipes through the card reader, the reset code in the target data can 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 or not is determined according to whether the reset code is stored in the card reader or not, and further whether the target card is a copy card is determined.
And S130, if the target card 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, which indicates that the target card has been swiped or that the same card as the target card has been already used, the target card is not reusable, and the target card can be determined to be a duplicate card.
That is, whether the target card is a duplicate card may be determined according to whether a reset code corresponding to the target card is stored in the card reader.
According to the technical scheme, 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 or not can not be determined due to the fact that the data stored in each copy card are all initial rolling codes in the prior art can be solved, and the technical effect of quickly, conveniently and accurately determining whether the target card is the copy card is achieved.
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 a reset code in the target card is updated to the preset data.
It can be understood that if the card reader does not store the data corresponding to the reset code in the target card, the target card is considered to be used for the first time, and the permission data in the target data can be acquired to perform permission verification, so that after the permission 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 be preset data.
The method has the advantages that whether the target card is used for the first time can be quickly determined, and whether the target card is a copied card can be determined based on the copy code.
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, the address data of the card swiping record in the target data can be further combined to determine whether the target card is the copy card or whether the copy card exists. Fig. 2 is a flowchart of a method for detecting a copy card according to a second embodiment of the present invention. Wherein, the technical terms identical to 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.
And S220, when the target data are 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 the copy 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 obtained.
It should be noted that, when the card is swiped, the address data recorded by the card may be marked, alternatively, when the card is swiped last time, the mark of the address data recorded by the card is 1, and when the card is swiped this time, the mark of the address data recorded by the card may be 2. The swipe recording address stored in the target data may be used as the current swipe recording address. The historical card swiping record address refers to card swiping record address data of a target card which can be marked after the target card is read by a card reader.
And S230, determining that the target card is 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 the historical card swiping record address data is not the current card swiping record address data but the historical card swiping record address data which is newly stored, the data is read by other cards through the card reader, and the target card can be determined to be the copy card; or if the latest data of the historical digital card recording address is inconsistent with the current digital card recording address data, the fact that other cards read the data through the card reader is indicated, and the target card can be determined to be the 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, permission information in the target data is acquired, so that whether the card-swiping can pass or not can be determined according to the permission information.
It is understood that the target data further includes permission data, and the permission data may be access permission and/or floor permission. It should be noted that the permission data may be specifically set according to a specific application scenario, which is not limited herein.
Specifically, when there is no other card-punching record address data in the history card-punching record address data other than the current card-punching record address data, or the latest history card-punching record address data in the history card-punching record address data is consistent with the current card-punching record address data, the target card is considered not to be a duplicate card. At this time, the authority data stored in the target card may be acquired to perform an operation corresponding to the authority data, and optionally, the card swiping pass or the elevator is operated to the corresponding floor.
That is, when the rights information is consistent with the rights information stored in the card reader, the swipe card passes.
On the basis of the technical scheme, after the card swiping is passed, updating the reset code of the target data in the target chip into preset data, and updating the card reader and the card swiping record address data in the target data into the current card swiping record address data so as to determine whether the target card is a copy card or not 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 address data of the target card is 14, the address data of the historical address data of the target card is 14, and the card reader and the address data of the target card can be updated to 15 when the card passes. Meanwhile, the reset code in the target data can be updated to preset data, and optionally, the preset data is 0.
According to the technical scheme, when the reset code is determined to be consistent with the preset data, the historical card record address data in the card reader and the current card swiping record address data in the target data can be further obtained, whether the target card is a copy card or not is rapidly determined based on the historical card record address data and the current card swiping record address data, and 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 of storing data in a target card in advance according to a third embodiment of the present invention. Wherein, the technical terms identical to or corresponding to the above embodiments are not repeated herein.
As shown in fig. 3, the method includes:
s310, generating a unique reset code ID by adopting a snowflake algorithm.
The new card issued by the card issuing system comprises a chip for storing data, authority data corresponding to the card can be written in a sector of the chip, and information such as an address initial value, a card reset code and the like is recorded by swiping the card.
The snowflake algorithm refers to an algorithm for generating a unique identifier, and aims to solve the problem that a large amount of data is gushed in a high concurrency period, and the algorithm can be generated when each resource is required to be identified.
In this embodiment, the generation of the unique reset code ID 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 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.
S320, initializing a card swiping record address value.
Specifically, initializing the address value of the card-swiping record may be setting the address value of the card-swiping record to an initial value, and optionally, the initial value may be 0.
S330, determining the authority data corresponding to the card.
Where rights refer to the scope and extent to which something is decided.
It should be noted that, the permission data corresponding to different application scenarios may be different, for example, if the elevator enters the home after the application scenario is swiped, the permission data may be a floor permission; if the application scene is a card swiping access district, the permission data can be access permission and the like.
It can be specifically understood that corresponding permission data can be written in the target card according to a specific application scene, so that the user has corresponding permission when the user swipes the card and goes out.
S340, encrypting the authority data, the card swiping record address value and the reset code ID by adopting an encryption algorithm, and storing the ciphertext obtained by the encryption process into a sector in the target card.
It should be noted that, any encryption algorithm may be used to encrypt the mentioned 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, a 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 decrypted data.
And after the authority data, the card-swiping recorded address value and the reset code ID are encrypted, a corresponding ciphertext is obtained. Accordingly, a sector may be a storage area for storing ciphertext.
Specifically, the entitlement data, the initial value of the swipe record address and the reset code ID are encrypted by adopting an encryption algorithm to obtain a ciphertext corresponding to the entitlement data, and the ciphertext can be stored in a sector of a target chip in the target card.
On the basis of the above, after the card issuing system sends the target card, the card reader may read the target data stored in the target card, and further determine whether the target card is a duplicate card 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 is obtained after the reset code, the card swiping record address value and the authority data are encrypted. The ciphertext data can be decrypted by adopting a decryption algorithm corresponding to the encryption algorithm, so as to obtain target data of the target card, namely a reset code, a card swiping record address value and authority data.
S402, judging whether the reset code is preset data or not, if so, executing S403; if not, S404 is performed.
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 it can acquire whether the reset code corresponding to the card is stored in the storage area of the card reader, and further determine whether the target card is a copy card, that is, execute S404.
S403, acquiring a current card swiping record address, judging whether a historical card swiping record address stored in a card reader comprises the current card swiping record address, and if yes, executing S405; if not, S406 is performed.
It should be noted that, when the card is swiped through, the address of the card swipe record may be recorded, for example, when the first card swipe is finished, the address of the card swipe record may be 1, when the second card swipe is finished, the address of the card swipe record may be 2, and when the card swipe is added, the address of the card swipe record may be increased by 1, and optionally, when the nth card swipe is finished, the address of the card swipe record may be N.
The current swipe recording address may be a swipe recording 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 a history swipe record address value corresponding to the target card.
Specifically, when the reset code in the target data is consistent with the preset data, 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. When the historical card swiping record address comprises a card swiping record address except the current card swiping record address, the existence of the copy card corresponding to the target card is indicated. If the historical card swiping record address does not include the card swiping record address except the current 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 other than 10 in the read historical card-swiping record address indicates that the card reader has read the copy card of the card, at this time, the card with the current card-swiping record address of 11 may be taken as the target card, at this time, the target card used is the copy card, and the use cannot be continued, i.e. 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 not considered to be a duplicate card, that is, S406 is executed.
S404, judging whether a reset code is stored in the card reader or not, if yes, executing S405; if not, then S407 is performed.
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 can be obtained, if yes, it is indicated that the target card is not used for the first time, and the target card may be a duplicate 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, namely, the 64-bit unique ID generated by adopting a snowflake algorithm can be read, 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 to 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 can be determined to be the copy card based on the above manner.
S406, reading the authority data and confirming passing.
It can be understood that after the verification of the reset code and the address of the card swiping record is completed, the permission data stored in the target card can be further read after the target card is determined not to be a duplicate card, so as to determine whether the card swiping can pass according to the read permission data.
Specifically, the authority data in the target data is acquired, if the authority data is detected to be legal, and optionally, the authority data is selected from the cell, the card can be swiped through, otherwise, the card cannot be swiped through.
S407, storing the reset code into the card reader.
It will be appreciated that in order to increase the efficiency of determining whether the target card is a duplicate card, after determining that the target card is initially in use, 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 to preset data.
S408, updating 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, 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 or not can not be determined due to the fact that the data stored in each copy card are all initial rolling codes in the prior art can be solved, and the technical effect of quickly, conveniently and accurately determining whether the target card is the copy card is achieved.
