[0002] When different organizations or companies cooperate with each other, they may need to verify the consistency of user data in order to achieve joint business marketing for users in the same region or with the same attributes. However, in order to protect user data privacy, no organization or company can transmit data to other companies, that is, plain text data cannot be directly sent to the other party for verification. After the data is desensitized, both parties need to verify the desensitized data.

[0003] In the prior art, the data to be verified is usually encrypted with random numbers to complete the desensitization operation. In the actual comparison process, if the data to be compared contains m groups of data, and each group of data contains k bits of data, it is necessary to use a random number generator to obtain 2 k *m random numbers to implement data encryption operations.

[0004] Then, in order to ensure that the random number encryption is not cracked, the prior art usually needs to set the length of the random number to 256 bits, resulting in a large storage space occupied by the random number, causing a waste of storage resources. Summary of the invention

[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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.

[0054] In the technical solution of this application, the collection, storage, use, processing, transmission, provision and disclosure of information such as financial data or user data involved shall comply with the provisions of relevant laws and regulations and shall not violate public order and good morals.

[0055] In the prior art, when different institutions or companies cooperate with each other, they need to desensitize the data. After the desensitized data is verified, the two parties can conduct joint business marketing for users in the same region or with the same attributes. However, when the data to be compared contains m groups of data, and each group of data contains k bits of data, each group of data needs to use a random number generator to obtain 2k random numbers to complete the data encryption operation. In order to perform sequence verification on the encrypted m groups of data, 2 k *m random numbers are used to implement sequence verification. In order to ensure that random number encryption cannot be cracked, the length of the random number is usually set to 256 bits, resulting in 2 k *The storage space occupied by m random numbers is relatively large, resulting in a waste of storage resources.

[0056] In order to solve the above technical problems, the embodiment of the present invention proposes the following technical solutions: by setting the second terminal to generate a grouped random number array in response to the data verification instruction sent by the first terminal and sending it to the first terminal, the first terminal can determine the operation array corresponding to each data block to be verified according to the parameters to be verified, the grouped random number array and the operation random number of all the data blocks to be verified, and set the data verification cooperation party to use the operation array to obtain the target verification random number corresponding to each data block to be verified. The present invention proposes a method for mapping the verification random number array of the second terminal to the first terminal using the grouped random number array, so that the first terminal and the second terminal respectively use the target verification random number and the verification grouped random number to complete the consistency verification of the data, thereby reducing the number of random numbers used in the data verification process, reducing the storage space occupied by the random number, and saving storage resources. The following detailed embodiments are used for detailed description.

[0057] Figure 1 Schematic diagram of the application scenario of the data verification method provided by the embodiment of the present invention. Figure 1As shown, the first terminal stores the business data of Company A, and the second terminal stores the business data of Company B. In order to achieve business cooperation, Company A and Company B need to perform consistency check on the overlapping business data in order to achieve joint business marketing for users in the same region or with the same attributes. Specifically, the first terminal acts as the initiator of data verification, and the first terminal sends the obtained data verification instruction to the second terminal, which is the cooperating party of data verification, so that the second terminal sends the group random number array generated in response to the data verification instruction sent by the first terminal to the first terminal, so that the first terminal can determine the operation array corresponding to each data block to be verified according to the parameters to be verified, the group random number array and the operation random number of all the data blocks to be verified, and set the data verification cooperating party to use the operation array to obtain the target verification random number corresponding to each data block to be verified. By using the group random number array generated by the second terminal, the verification random number array of the second terminal is mapped to the first terminal, so that the first terminal obtains the target verification random number, so that the first terminal and the second terminal respectively use the target verification random number and the verification group random number to complete the consistency check of the data, thereby reducing the number of random numbers used in the data verification process, reducing the storage space occupied by the random number, and saving storage resources.

[0058] Figure 2 Schematic diagram of the data verification method provided by the embodiment of the present invention Figure 1 , the execution subject of this embodiment can be Figure 1 The first terminal in the illustrated embodiment is not particularly limited in this embodiment.

[0059] like Figure 2 As shown, the method includes:

[0060] S201: Send the obtained data verification instruction to the second terminal, so that the second terminal generates a group random number array in response to the data verification instruction, generates a verification random number array according to the data length of the pre-stored verification data block, determines the verification group random number corresponding to each verification data block according to the verification parameter corresponding to each verification data block and the verification random number array, and sorts all the verification group random numbers according to the sequence number corresponding to each verification data block to obtain the verification group random number array.

[0061] In the embodiment of the present invention, the first terminal acts as the initiator of data verification, and the second terminal acts as the cooperator of data verification. The first terminal starts to trigger the data verification process according to the received data verification instruction. Specifically, the first terminal transmits the data verification instruction to the second terminal. The second terminal responds to the data verification instruction and generates a group random number array using a random number generator with quantum-resistant characteristics.

[0062] Exemplarily, before the second terminal generates the grouped random number array, the second terminal groups the verification data to obtain m groups of verification data blocks and stores them. Each verification data block contains k bits of data. The second terminal sorts the m groups of verification data blocks to obtain the sequence number of each verification data block. In the embodiment of the present invention, the second terminal generates the verification random number array according to the k-bit contained in each verification data block.

[0063] In the embodiment of the present invention, the second terminal also obtains the verification parameter of each verification data block according to the parameter of the verification data block. For example, if each verification data block contains a 3-bit parameter, if the parameter corresponding to the verification data block numbered 3 is 101 in binary, and the corresponding decimal verification parameter is 5, then the verification parameter of the third verification data block is determined to be 5. The d5 in is determined as the random number D3 of the check group corresponding to the third check data block. According to the check parameter p corresponding to the jth check data block and the check random number array Determine the random number D of the check group corresponding to each check data block j is d p Then, all the random numbers of the verification groups are sorted according to the serial number corresponding to each verification data block to obtain the random number array of the verification group {D1, D2, ..., D m}, where j is a positive integer less than or equal to m.

[0064] Exemplarily, in the process of grouping the verification data at the second terminal, the verification data may be padded so that the padded verification data is an integer multiple of k. Exemplarily, the verification data may be padded using a PKCS7 padding algorithm.

[0065] S202: Receive the group random number array and the verification group random number array sent by the second terminal, determine the target group random number corresponding to each data block to be verified according to the pre-stored parameters to be verified corresponding to each data block to be verified and the group random number array, and determine the operation array corresponding to each data block to be verified according to the generated operation random number and the target group random number corresponding to each data block to be verified.

[0066] In the embodiment of the present invention, at least one data block to be checked is stored in the first terminal, wherein the data block to be checked is obtained by the first terminal grouping the data to be checked, and accordingly, the first terminal also stores the sequence number and the parameter to be checked corresponding to each data block to be checked. The specific method of grouping and obtaining the parameter to be checked is consistent with the method implemented by the second terminal in S201, and will not be repeated here.

[0067] In the embodiment of the present invention, the first terminal determines the target group random number corresponding to each data block to be checked according to the pre-stored parameters to be checked corresponding to each data block to be checked and the group random number array r. Specifically, the first terminal selects the target group random number corresponding to each data block to be checked from the group random number array r according to the stored parameters to be checked corresponding to each data block to be checked For example, if each data block to be checked contains a 3-bit parameter, if the parameter corresponding to the data block to be checked with sequence number 3 is 101 in binary, and the corresponding decimal check parameter is 5, then the check parameter of the third data block to be checked is determined to be 5. The r5 in is determined as the target group random number corresponding to the third verification data block.

[0068] In the embodiment of the present invention, the first terminal pre-stores a random number for operation, wherein the random number for operation is generated by the first terminal using a random number generator with quantum resistance. The first terminal determines the operation array V corresponding to each data block to be checked according to the random number for operation and the target group random number corresponding to each data block to be checked. In the embodiment of the present invention, the first terminal encrypts the random number for operation using the public key of the second terminal, and calculates the random number according to the encrypted random number for operation and the target group random number r corresponding to the sth data block to be checked. n The sum of the obtained operation array V corresponding to the sth data block to be checked S For example, according to the encrypted operation random number and the target group random number r corresponding to the sth to-be-checked data block n Get the operation array V corresponding to the sth data block to be checked S The formula is shown in (1):

[0069] V S =r n +E(x,PK-b) (1)

[0070] Wherein, n is the parameter to be verified corresponding to the sth data block to be verified, s is a positive integer less than m, and E(x, PK-b) indicates that the operation random number is encrypted using the public key PK-b of the second terminal.

[0071] Exemplarily, if the parameter to be verified of the third data block to be verified is 5, and the target group random number corresponding to the third verification data block is r5, then the operation array V3 corresponding to the third data block to be verified is obtained by summing the encrypted operation random number and the target group random number r5 corresponding to the third data block to be verified, which is r5+E(x, PK-b). Specifically, the operation array corresponding to each data block to be verified can be obtained according to formula (1).

[0072] S203: Send all operation arrays to the second terminal, so that the second terminal determines the target verification random number array corresponding to each data block to be verified according to the operation array, the grouping random number array and the verification random number array corresponding to each data block to be verified.

[0073] In the embodiment of the present invention, the second terminal receives the operation array corresponding to all the data blocks to be checked. Afterwards, according to the operation array corresponding to each data block to be verified and the grouped random number array Determine the target verification random number array {Y1, Y2, ..., Y m}. Among them, the parameter to be checked corresponding to the sth data block to be checked is n, and the operation array V corresponding to the sth data block to be checked is S , the target verification random number array Y corresponding to the sth data block to be verified s for Specifically, The expression of is shown in formula (2):

[0074]

[0075] Where s is a positive integer less than m, and i is a positive integer less than 2. k A positive integer, D(V S -r i , sk-a) represents the operation array V corresponding to the s-th data block to be verified by the second terminal using the private key sk-b of the second terminal S With r i The second terminal decrypts the difference between the decrypted random number array D(V S -r i The i-th decryption random number in sk-b) is respectively combined with the i-th verification random number in the verification random number array to obtain the i-th target verification random number corresponding to the s-th data block to be verified, and the i-th target verification random number corresponding to the s-th data block to be verified is calculated according to the first target verification random number to the second target verification random number. k The target check random number determines the target check random number array Y of the sth data block to be checked s .

[0076] In the embodiment of the present invention, according to formula (1) V S =r n +E(x,PK-b), only D(V S -r n ,sk-b) can be correctly decrypted to obtain the operation random number, that is, the target verification random number array Y corresponding to the sth data block to be verified s for In, only The corresponding V S -r n is the correct random number obtained after decryption, and the rest are random numbers in disorder, so is d n +x.

[0077] S204: Receive all target verification random number arrays and sorted verification group random numbers sent by the second terminal, determine the target random number corresponding to each data block to be verified according to the target verification random number array corresponding to each data block to be verified, the calculated random number, and the verification parameter corresponding to each data block to be verified, and sort all target random numbers according to the serial number corresponding to each data block to be verified to obtain the target random number array.

[0078] In the embodiment of the present invention, after obtaining the target verification random number array corresponding to each data block to be verified, the first terminal obtains all target random numbers corresponding to each data block to be verified according to the target verification random number array y corresponding to each data block to be verified and the calculated random number. Specifically, the target verification random number array Y of the sth data block to be verified s for According to Y s Each target check random number in The difference between the calculated random number and the target random number is obtained to obtain the i-th target random number corresponding to the s-th data block to be verified. Specifically, The calculation formula is shown in formula (3):

[0079]

[0080] In the embodiment of the present invention, the first target random number corresponding to the sth data block to be checked can be obtained according to (3): To 2nd k Target random number The parameter to be checked corresponding to the sth data block to be checked is n, and the nth target random number As the target random number z corresponding to the sth data block to be verified s According to formulas (2) and (3), the first target random number corresponding to the sth data block to be checked is To 2nd k Target random number In, only In The correct random number obtained after decryption, due to is d n +x, then is d n , d nThat is, the nth target random number determined by the parameter to be verified corresponding to the sth data block to be verified

[0081] In the embodiment of the present invention, all target random numbers are sorted according to the sequence number corresponding to each data block to be checked to obtain a target random number array, so that the target random number arrays {Z1, Z2, ..., Z2} corresponding to the first data block to be checked to the mth data block to be checked can be obtained. m}.

[0082] S205: If it is determined that each random number in the random number array of the verification group is consistent with each random number in the target random number array in sequence, then it is determined that the data verification is successful.

[0083] In the embodiment of the present invention, the m groups of check data blocks stored in the second terminal correspond to {D1, D2, ..., D m}, the m groups of to-be-checked data blocks stored in the first terminal correspond to {Z1, Z2, ..., Z m}. For example, according to formula (1), formula (2) and formula (3), it can be deduced that the nth target random number corresponding to the sth to-be-checked data block is is d n , that is, the target random number corresponding to the s-th data block to be verified matches the parameter to be verified corresponding to the s-th data block to be verified. If the verification parameter corresponding to the s-th verification data block in the second terminal is also n, it can be determined that the target random number corresponding to the s-th data block to be verified is consistent with the verification group random number corresponding to the s-th verification data block. If the target random numbers corresponding to the m groups of data blocks to be verified are respectively consistent with the verification group random numbers corresponding to the m groups of verification data blocks, that is, the m groups of data blocks to be verified stored in the first terminal are consistent with the m groups of verification data blocks stored in the second terminal, it is determined that the data verification is successful.

[0084] The data verification method provided by the embodiment of the present invention sets a data verification cooperator to send the generated group random number array to the initiator of data verification, so that the initiator of data verification can determine the operation array corresponding to each data block to be verified according to the to-be-verified parameters of all the data blocks to be verified, the group random number array and the operation random number, and sets the data verification cooperator to use the operation array to obtain the target verification random number corresponding to each data block to be verified, thereby achieving the purpose of mapping the verification random number array of the data verification cooperator to the data verification initiator, so that the data verification cooperator and the initiator respectively use the verification group random number and the target verification random number to realize data consistency verification, thereby reducing the number of random numbers required in the data verification process, reducing the storage space occupied by random numbers, and saving storage resources.
