[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The smart card verification method based on the smart door lock provided by the embodiment of the present invention can be applied in Figure 1In the application environment, the target terminal 110 communicates with the smart door lock 120 through the network 130. When the smart door lock 120 is unlocked at the first time, the first target operation data stored in advance can be obtained from the smart door lock, and the second target operation data can be obtained from the smart card, wherein the first target operation data is the operation data generated when the smart door lock is unlocked at the second time, and the second target operation data is the operation data generated when the smart door lock is unlocked at the second time, and the second time is earlier than the first time; according to the first target operation data and the second target operation data, the smart card is security verified to obtain an operation verification result, and the operation verification result is returned to the target terminal 110. In the present invention, when the smart door lock is unlocked at the first time, the first target operation data stored in advance can be obtained from the smart door lock, and the second target operation data can be obtained from the smart card, wherein the first target operation data is the operation data generated when the smart door lock is unlocked at the second time, and the second target operation data is the operation data generated when the smart door lock is unlocked at the second time, and the second time is earlier than the first time; according to the first target operation data and the second target operation data, the smart card is security verified to obtain an operation verification result. In the present application, when unlocking at the second time, the first target operation data is stored in the smart door lock, and the second target operation data is stored in the smart card. When unlocking at the first time, the first target operation data and the second target operation data corresponding to the second time are compared to verify the security of the smart card to determine whether the smart card has been copied, thereby improving the security and reliability of the application of the smart card. Among them, the target terminal 110 can be, but is not limited to, various smart phones 110-1, tablet computers 110-2, and laptop computers 110-3. The present invention is described in detail below through specific embodiments.

[0023] See also Figure 2 As shown, Figure 2 The present invention provides a flow chart of a smart card verification method based on a smart door lock. This embodiment uses the method applied to a smart door lock as an example. The smart card verification method based on a smart door lock includes the following steps S100 to S200:

[0024] S100: When unlocking at the first time, obtain the pre-stored first target operation data from the smart door lock, and obtain the second target operation data from the smart card, wherein the first target operation data is the operation data generated when the smart door lock is unlocked at the second time, and the second target operation data is the operation data generated when the smart door lock is unlocked at the second time, and the second time is earlier than the first time.

[0025] Among them, the first time is the time when the smart door lock is unlocked this time, and the second time is the time when the smart door lock was unlocked last time. For example, assuming that the time when the smart door lock is unlocked this time is 10:10 on July 10, 2023, the first time is 10:10 on July 10, 2023. Assuming that the time when the smart door lock was unlocked last was 12:10 on July 10, 2023, the second time is 12:10 on July 10, 2023.

[0026] The first target operation data stored in the smart door lock includes characteristic data such as door lock identification, first operation time, first unlocking times, first recording location information, etc. Among them, the first operation time refers to the second time stored in the smart door lock when unlocking at the second time, the first unlocking times refers to the unlocking times stored in the smart door lock when unlocking at the second time (such as the 10th unlocking in July, the 1st unlocking on July 10), and the first recording location information refers to the storage address information of the second target operation data stored in the smart door lock and the storage address information of the first target operation data. The door lock identification can be data that uniquely identifies a smart door lock, such as the door lock name and door lock ID.

[0027] The second target operation data stored in the smart card includes characteristic data such as door lock identification, second operation time, second unlocking times, second recording location information, etc., wherein the second operation time refers to the second time stored in the smart card when unlocking at the second time, the second unlocking times refers to the unlocking times stored in the smart card when unlocking at the second time, and the second recording location information refers to the storage address information of the second target operation data stored in the smart card when unlocking at the second time and the storage address information of the first target operation data.

[0028] It can be understood that the second target operation data can be a null value.

[0029] S200: Perform security verification on the smart card according to the first target operation data and the second target operation data to obtain an operation verification result.

[0030] Optionally, the door lock identifier can be first obtained from the first target operation data, and the smart card can be verified based on the door lock identifier to see whether it is consistent with the door lock identifier in the second target operation data. If the two door lock identifiers are consistent, it means that the smart card matches the smart door lock, thereby performing security verification on the smart card. That is, the first target operation data and the second target operation data are compared for consistency to obtain a consistency comparison result indicating whether the smart card has been copied. If the two door lock identifiers are inconsistent, it means that the smart card does not match the smart door lock, and the smart door lock terminates the unlocking operation, and uses the comparison result of the door lock identifier and the consistency comparison result as the operation verification result.

[0031] The operation verification result may indicate whether the smart card has been copied. If the smart card has not been copied, the operation verification result is passed; if the smart card has been copied, the operation verification result is failed.

[0032] Among them, if the smart card has not been copied, the first target operation data corresponding to the smart door lock and the second target operation data corresponding to the smart card should be consistent. If the smart card is copied, the first target operation data corresponding to the smart door lock and the second target operation data corresponding to the smart card should be inconsistent, so as to verify the security of the smart card.

[0033] Optionally, determining whether the first target operation data and the second target operation data are encrypted data;

[0034] If the first target operation data and the second target operation data are encrypted data, the first target operation data and the second target operation data are decrypted respectively, and then based on a similarity algorithm, the similarity between the first target operation data and the second target operation data is calculated to obtain a similarity value;

[0035] If the first target operation data and the second target operation data are not encrypted data, similarity between the first target operation data and the second target operation data is calculated based on a similarity algorithm to obtain a similarity value.

[0036] According to the similarity value, the operation verification result is obtained.

[0037] Optionally, after obtaining the first target operation data, the memory in the smart door card can be searched for the existence of second target operation data corresponding to the first target operation data based on the first target operation data, thereby generating an operation verification result. If the operation verification result indicates existence, it is determined that the smart card has not been copied; if the operation verification result indicates non-existence, it is determined that the smart card has been copied.

[0038] In this embodiment, when unlocking at the first time, the first target operation data pre-stored is obtained from the smart door lock, and the second target operation data is obtained from the smart card, wherein the first target operation data is the operation data generated when the smart door lock is unlocked at the second time, and the second target operation data is the operation data generated when the smart door lock is unlocked at the second time, and the second time is earlier than the first time; according to the first target operation data and the second target operation data, the smart card is security verified to obtain an operation verification result. In this application, when unlocking at the second time, the first target operation data is stored in the smart door lock, and the second target operation data is stored in the smart card, and when unlocking at the first time, the first target operation data and the second target operation data corresponding to the second time are compared to perform security verification on the smart card to determine whether the smart card has been copied, thereby improving the security and reliability of the application of smart cards.

[0039] In some optional implementations of this embodiment, before step S100, that is, before obtaining the pre-stored first target operation data from the smart door lock, the method further includes the following steps S300 to S500:

[0040] S300: When unlocking the door at the second time, the operation data generated by the smart door lock during the unlocking process is used as the first target operation data and the second target operation data.

[0041] When unlocking at the second time, the operation data generated during the unlocking process, such as the recorded location information, operation time (ie, unlocking time), number of unlocking times, etc., are used as the first target operation data and the second target operation data.

[0042] S400: Storing the first target operation data into a memory in the smart door lock.

[0043] Optionally, storing the first target operation data in a memory in the smart door lock includes:

[0044] Separate the keyword and value in the first target key-value pair corresponding to the first target operation data to obtain the first target keyword (such as the first operation time) and the first target value (the first operation time, the first unlocking number, the first recording location information), wherein the first target keyword is the timestamp corresponding to the first operation time;

[0045] Establishing a first corresponding relationship between a first target keyword and a first target value;

[0046] The first target keyword, the first target value, and the first corresponding relationship are stored in a memory in the smart door lock.

[0047] Furthermore, when searching for the first target operation data, the first target keyword is queried, and according to the first corresponding relationship, the first target value is obtained from the memory in the smart door lock, that is, the first target operation data is obtained.

[0048] In this step, by separating the keywords and values ​​in the first target key-value pair, the flexibility of generating timestamps is improved, the efficiency of data storage is improved, and it is also beneficial to quickly query the first target operation data corresponding to the timestamp when performing security verification on the smart card, thereby improving the verification efficiency of the smart card.

[0049] S500: Store the second target operation data into a sector in the smart card.

[0050] Optionally, storing the second target operation data in a sector in a smart card includes:

[0051] Separate the keyword and value in the second target key-value pair corresponding to the second target operation data to obtain the second target keyword (such as the second operation time) and the second target value (the second operation time, the second unlocking times, and the second recording location information), wherein the second target keyword is the timestamp of the second operation time;

[0052] Establishing a second corresponding relationship between a second target keyword and a second target value;

[0053] The second target keyword, the second target value, and the second corresponding relationship are stored in a sector in the smart card.

[0054] Furthermore, when searching for the second target operation data, the second target keyword is queried and, according to the second corresponding relationship, the second target value is obtained from the sector in the smart card, that is, the second target operation data is obtained.

[0055] In this step, by separating the keyword and value in the second target key-value pair, the flexibility of generating timestamp is improved, and it is also beneficial to quickly query the second target operation data corresponding to the timestamp when verifying the security of the smart card, thereby improving the verification efficiency of the smart card.

[0056] It should be noted here that if the smart card is not copied, the operation data generated during the unlocking process will be used as the first target operation data and the second target operation data, that is, the first target operation data and the second target operation data are consistent. If the smart card is copied, the second target operation data does not exist in the smart card, and the first target operation data corresponding to the second target operation data is stored in the smart door lock, so that when comparing the first target operation data and the second target operation data, data inconsistency occurs.

[0057] In this embodiment, the operation data generated when unlocking the door at the second time is used as the first target operation data and the second target operation data, and are stored in the memory in the smart door lock and the sector in the smart card respectively. Through this distributed storage method, the security of the data storage of both parties is guaranteed, which is beneficial to improve the security and reliability of the operation verification results when the security verification of the smart card is performed, thereby improving the security and reliability of the application of the smart card.

[0058] In some optional implementations of this embodiment, in step S300, when unlocking at the second time, the operation data generated by the smart door lock during the unlocking process is used as the first target operation data and the second target operation data, including the following steps S310 to S340:

[0059] S310: When unlocking the door at the second time, the operation data generated by the smart door lock during the unlocking process is used as the first initial operation data and the second initial operation data.

[0060] The first initial operation data includes characteristic data such as door lock identification, first initial operation time, first initial unlocking times, first initial recording location information, etc. The first initial operation time refers to the second time stored in the smart door lock when unlocking at the second time, the first initial unlocking times refers to the unlocking times stored in the smart door lock when unlocking at the second time, and the first recording location information refers to the storage address information of the second target operation data stored in the smart door lock when unlocking at the second time and the storage address information of the first target operation data.

[0061] The second initial operation data includes characteristic data such as door lock identification, second initial operation time, second initial unlocking times, second initial recording location information, etc., wherein the second initial operation time refers to the second time stored in the smart card when unlocking at the second time, the second unlocking times refers to the unlocking times stored in the smart card when unlocking at the second time, and the second initial recording location information refers to the storage address information of the second target operation data stored in the smart card when unlocking at the second time and the storage address information of the first target operation data.

[0062] S320: Using an encryption algorithm, encrypt the first initial operation data and the second initial operation data respectively to obtain first encrypted operation data corresponding to the first initial operation data and second encrypted operation data corresponding to the second initial operation data.

[0063] Among them, the encryption algorithm can be a hash algorithm, a symmetric encryption algorithm, an asymmetric encryption algorithm, etc., which is selected according to the actual application scenario. This application does not make specific limitations on the encryption algorithm.

[0064] S330: Using the first encrypted operation data as the first target operation data.

[0065] S340: Use the second encrypted operation data as second target operation data.

[0066] In this embodiment, the first initial operation data and the second initial operation data are encrypted by adopting an encryption algorithm to obtain the corresponding first encrypted operation data and the second encrypted operation data, so that the first Mijia operation data is used as the first target operation data, and the second encrypted operation data is used as the second target operation data, thereby ensuring the security of the data storage of both parties, so as to improve the security and reliability of the operation verification results when the security verification of the smart card is performed, thereby improving the security and reliability of the application of the smart card.

[0067] In some optional implementations of this embodiment, the second time includes at least one unlocking time, and step S100, when unlocking at the first time, obtains pre-stored first target operation data from the smart door lock, and obtains second target operation data from the smart card, including the following steps S110 to S120:

[0068] S110: When unlocking the smart door lock for the first time, obtain all operation data in the smart door lock, and splice each operation data in the smart door lock according to the unlocking time corresponding to each operation data in the smart door lock to obtain the first target operation data.

[0069] Among them, all first operation data refer to the operation data (such as door lock identification, operation time, number of unlocking, recorded location information and other unique characteristic data) generated each time the smart door lock is unlocked in a historical time period (such as month, week, etc.), and is stored in the memory in the smart door lock.

[0070] For example, all first operation data in the smart door lock within the past week starting from the first time are obtained, that is, the operation data corresponding to each unlocking time within the past week starting from the first time, and each first operation data is spliced ​​according to the time corresponding to each first operation data to obtain the first target operation data.

[0071] S120: Acquire all operation data in the smart card, and concatenate the operation data in the smart card according to the unlocking time corresponding to each operation data in the smart card to obtain second target operation data.

[0072] Among them, all second operation data refer to the operation data (such as operation time, number of unlocking, recorded location information and other unique characteristic data) generated each time the smart door lock is unlocked in a historical time period (such as month, week, etc.), and is stored in the sector in the smart card.

[0073] For example, all second operation data in the past week starting from the first time in the smart card are obtained, and the second operation data are spliced ​​according to the time corresponding to each second operation data to obtain the second target operation data.

[0074] In this embodiment, the first target operation data is obtained by acquiring all the first operation data and splicing them in chronological order, thereby the first target operation data includes all the first operation data connected in order in chronological order, and all the second operation data are acquired and spliced ​​in chronological order to obtain the second target operation data, thereby the second target operation data includes all the second operation data connected in order in chronological order, thereby using all the second operation data in the smart card and all the first operation data in the smart door lock to perform security verification on the smart door card, thereby improving the security and reliability of the operation verification results, thereby improving the security and reliability of the application of the smart card.

[0075] In some optional implementations of this embodiment, after step S200, that is, after performing security verification on the smart card according to the first target operation data and the second target operation data to obtain an operation verification result, the method further includes the following steps S210 to S213:

[0076] S210: If the operation verification result is passed, the operation data generated when the first unlocking is obtained as the data to be stored.

[0077] Among them, if the operation verification result is passed, it means that the smart card has not been copied, and the operation data generated when unlocking for the first time may include the operation time, the number of unlocking times, and the recorded location information, wherein the recorded location information includes the storage address of the memory in the smart door lock and the storage address of the sector in the smart card.

[0078] S211: Randomly select a sector storing operation data from sectors of the smart card as a sector to be processed, and update the sector to be processed with the data to be stored.

[0079] The to-be-processed sector is updated with the to-be-stored data, that is, the operation data in the to-be-processed sector is deleted, and the to-be-stored data is stored in the to-be-processed sector.

[0080] S212: randomly obtaining a storage address from the memory as the target storage address, and using the data to be stored to update the operation data corresponding to the target storage address.

[0081] The storage address is a memory address, which is the number of a storage unit in the memory. Since there are a large number of storage units in the memory, the memory address is used to query the storage data of the storage unit corresponding to the memory address.

[0082] S213: Store the serial number of the to-be-processed sector in association with the target storage address in the memory.

[0083] Optionally, if the operation verification result is passed, the operation data generated when the first unlocking is obtained as the data to be stored, and the stored data detection is performed on each sector in the smart card;

[0084] If it is detected that all sectors in the smart card are full of operation data, the sector with the earliest storage time of the operation data is used as the target sector, and the operation data in the target sector is updated with the data to be stored;

[0085] If it is detected that the sectors in the smart card are not fully written with the operation data, the data to be stored is updated to the sectors that do not store the operation data.

[0086] In this embodiment, by randomly selecting a target storage address and a sector to be processed, and using the data to be stored to update the operation data corresponding to the target storage address and the operation data corresponding to the sector to be processed, the randomness of data storage is used, and the serial number of the sector to be processed and the target storage address are associated and stored to facilitate subsequent data query. This is beneficial to improving the security and reliability of the operation verification results when performing security verification on the smart door card, thereby improving the security and reliability of the application of the smart card.

[0087] In some optional implementations of this embodiment, after step S200, that is, after performing security verification on the smart card according to the first target operation data and the second target operation data to obtain an operation verification result, the method further includes the following steps S220 to S224:

[0088] S220: If the operation verification result is passed, obtain the pre-stored first encrypted unlocking data, and obtain the second encrypted unlocking data from the smart card.

[0089] The first encrypted unlocking data is a key pre-set and stored in the smart door lock, and the second encrypted unlocking data is a second encrypted unlocking data pre-set and stored in the smart card.

[0090] The first encrypted unlocking data and the second encrypted unlocking data may be hash values ​​obtained by encrypting a password set by a user using a hash algorithm.

[0091] S221: Performing unlock password verification on the smart card according to the first encrypted unlock data and the second encrypted unlock data to obtain an unlock password verification result.

[0092] S222: If the unlock password verification result is passed, the smart door lock is controlled to unlock.

[0093] Among them, if the unlock password verification result is passed, it means that the second encrypted unlock data of the smart card is correct, so that an unlock instruction is generated, so that the smart door lock responds to the unlock instruction to unlock.

[0094] S223: If the unlock password verification result is failed, a door lock safety alarm message is generated according to the unlock password verification result.

[0095] Among them, if the unlocking password verification result is passed, it means that the second encrypted unlocking data of the smart card is incorrect, so that a door lock security alarm instruction is generated, so that the smart door lock generates a door lock security alarm information in response to the door lock security alarm instruction.

[0096] The door lock safety alarm information can be any one or more of sound information, text information, photoelectric information, etc.

[0097] S224: If the operation verification result is failed, a duplicate card alarm message is generated according to the first time and the second time.

[0098] The copy card alarm information may be any one or more of sound information, text information, photoelectric information, link information, etc.

[0099] In this embodiment, it is first determined whether the operation verification result of the smart card is passed. If the operation verification result is passed, the smart card key verification is performed. If the unlocking password verification result is passed, the smart door lock is controlled to unlock. Otherwise, a door lock security alarm message is generated. If the operation verification result fails, a copy card alarm message is generated to improve the security and reliability of the application of smart cards, thereby enhancing the security and reliability of smart door locks.

[0100] In some optional implementations of this embodiment, after step S224, that is, after generating a duplicate card alarm message according to the first time and the second time if the operation verification result is not passed, the method further includes the following steps S2240 to S2242:

[0101] S2240: Based on the copy card alarm information, an identity authentication instruction is sent to the target terminal, wherein the target terminal is used to: respond to the identity authentication instruction to guide the user to perform identity authentication, generate an identity authentication result, and if the identity authentication result is passed, send a card unlock password verification instruction to the smart door lock; if the identity authentication result is failed, send an alarm instruction to the smart door lock.

[0102] Among them, the target terminal can be a mobile phone, tablet, face recognition device or fingerprint authentication device, etc. The target terminal is connected to the smart door lock through a wired or wireless method, and the identity authentication can verify one or more of the user's fingerprint information, facial feature information, ID card information, etc.

[0103] S2241: In response to the card unlocking password verification instruction, the unlocking password of the smart card is verified, and the operation data in the smart door lock and the operation data in the smart card are initialized.

[0104] Optionally, in response to the card password verification instruction, unlock confirmation information is obtained, and the unlock confirmation information indicates whether the user is sure to unlock. If the unlock confirmation information indicates that the user is sure to unlock, the unlock password of the smart card is verified, otherwise, the unlocking is terminated.

[0105] S2242: In response to the alarm instruction, a door lock security alarm message is issued.

[0106] The door lock security alarm information can be one or more of sound information, text information, photoelectric information, etc.

[0107] In this embodiment, the duplicate card alarm information is sent to the target terminal to guide the user to perform identity authentication. If the identity authentication result is passed, it means that the user identity is normal, then the smart card is unlocked and the password is verified, and the operation data in the smart door lock and the operation data in the smart card are initialized, thereby improving the intelligence of the smart door lock. If the identity authentication result is failed, it means that the user identity is abnormal, then a door lock security alarm message is issued, thereby improving the security and reliability of the application of smart cards, as well as the security and reliability of the application of smart door locks.

[0108] In one application scenario, if the smart door lock corresponds to multiple smart cards, the memory in the smart door lock is divided into multiple storage areas, each storage area is composed of multiple continuous or discontinuous memory units, and the memory unit is used to store the first target operation data generated by the smart card after unlocking the smart door lock, and the storage area and the smart card correspond one to one. For example, when the smart card 1 unlocks the smart door lock at the second time, the operation data generated by the smart door lock 1 during the unlocking process is stored in the sector of the smart card 1 and the storage area corresponding to the smart card 1 in the smart door lock respectively.
