Description

User information joint processing method, device, equipment and computer readable medium

Technical Field

Embodiments of the present disclosure relate to the field of computer technology, and in particular, to a method, an apparatus, a device, and a computer readable medium for user information joint processing.

Background

In the user information joint processing, the data check party (parent company) holds all check rules, and data required for checking is stored only in the data check party, and each data to be checked party (subsidiary company) does not have any data required for checking. The data verifier also has no raw data for each data to be verified. At present, the original data reported by each data checked party is mainly obtained from the plaintext of the data checked party, the original data reported by each data checked party is checked according to the check rule, so that the original data reported by each data checked party is normalized, and the normalized data is sent to each data checked party. Moreover, the data checking party does not have data required for checking the original data reported by the data checked party, and the data checking party needs to manually check and normalize the original data reported by the data checked party.

However, the inventors found that when the information joint processing is performed in the above manner, there are often the following technical problems:

Firstly, the data checking party plain text obtains the original data of each data checked party, so that the original data of each data checked party are all exposed to the data checking party, the data checking party is attacked, the risk of the original data of each data checked party being revealed is higher, and the safety of the data is lower. And because the data checking party also has no original data of each data checked party, the original data of the data checking party and the data checked party are secret, and plaintext data exchange can not be carried out, so that user information joint processing can not be carried out.

Secondly, the data required by the verification of the original data reported by the data checked party does not exist in the data checked party, and the original data reported by the data checked party is required to be subjected to the verification and normalization processing manually, so that the efficiency of the joint processing of the user information is lower.

Third, because the data required for checking is only stored in the data checking party, more redundant data exists in the common storage mode, so that the query efficiency of the data required for checking is lower, and when each data is checked by the checking party by frequently sending the original data, the checking efficiency is lower.

The above information disclosed in this background section is only for enhancement of understanding of the background of the inventive concept and, therefore, may contain information that does not form the prior art that is already known to those of ordinary skill in the art in this country.

The above embodiments of the present disclosure have the following advantageous effects: by the user information joint processing method of some embodiments of the present disclosure, the security of the user information is improved. Specifically, the reason why the security of the user information is low is that: the data checking party plain text obtains the original data of each data checked party, so that the original data of each data checked party are all exposed to the data checking party, the data checking party is attacked, the risk of the original data of each data checked party being revealed is higher, and the safety of the data is lower. And because the data checking party also has no original data of each data checked party, the original data of the data checking party and the data checked party are secret, and plaintext data exchange can not be carried out, so that user information joint processing can not be carried out. Based on this, in the user information joint processing method of some embodiments of the present disclosure, first, encryption processing is performed on each standard user identity information included in a pre-stored standard user information set and each abnormal user identity information included in a pre-stored abnormal user information mapping relation set, so as to obtain each encrypted standard user identity information and each encrypted abnormal user identity information, and the encryption information is sent to each participating processing sub-node, so that the participating processing sub-node in each participating processing sub-node performs encryption processing on each user identity information to be normalized, where the pre-stored standard user information in the pre-stored standard user information set includes standard user identity information, and the pre-stored abnormal user information mapping relation in the pre-stored abnormal user information mapping relation set includes abnormal user identity information and normalized user identity information corresponding to the abnormal user identity information. Thus, each piece of encrypted standard user identity information and each piece of encrypted abnormal user identity information can be obtained. And then, in response to receiving the first check information sent by the participating processing sub-node in each participating processing sub-node, performing check processing on the first check information according to the user identity information of each encryption standard to obtain a first check result, and sending the first check result to the participating processing sub-node. Thus, a first verification result can be obtained, and the first verification result can represent whether the encryption standard user identity information corresponding to the first verification information exists in the encryption standard user identity information. And then, in response to receiving second check information sent by the participating processing sub-node, performing check processing on the second check information according to the encrypted abnormal user identity information to obtain a second check result, and sending the second check result to the participating processing sub-node. Thus, a second check result can be obtained, and the second check result can represent whether the encrypted abnormal user identity information corresponding to the second check information exists in the encrypted abnormal user identity information. And then, determining the standard user information corresponding to the user identity information to be standardized in response to receiving the feedback information sent by the participating processing child node, wherein the feedback information comprises the user identity information to be standardized. Thus, the standard user information corresponding to the user identity information to be standard can be obtained. The standard user information may represent standard user identity information or standard user information corresponding to the user identity information to be specified. And then, according to the user identity information to be normalized and the normalized user information corresponding to the user identity information to be normalized, updating the pre-stored standard user information set and the pre-stored abnormal user information mapping relation set to obtain an updated user information set and an updated abnormal user information mapping relation set, wherein the updated user information in the updated user information set comprises updated standard user identity information, and the updated abnormal user information mapping relation in the updated abnormal user information mapping relation set comprises updated abnormal user identity information. Thus, the updated pre-stored standard user information set and the pre-stored abnormal user information mapping relation set can be obtained. And then, carrying out encryption processing on each piece of updating standard user identity information included in the updating user information set and each piece of updating abnormal user identity information included in the updating abnormal user information mapping relation set to obtain each piece of encryption updating standard user identity information and each piece of encryption updating abnormal user identity information. Therefore, the user identity information of each encryption updating standard and the user identity information of each encryption updating abnormal can be obtained and can be used for re-checking the check information sent by the participating processing child nodes. And then, in response to receiving the third verification information sent by the participating processing sub-node, performing verification processing on the third verification information according to the encryption updating standard user identity information to obtain a third verification result, and sending the third verification result to the participating processing sub-node. Therefore, a third checking result can be obtained, and the third checking result can represent whether the encryption updating standard user identity information corresponding to the third checking information exists in the encryption updating standard user identity information. And finally, responding to the received fourth check information sent by the participating processing sub-node, carrying out check processing on the fourth check information according to the encryption updating abnormal user identity information to obtain a fourth check result, and sending the fourth check result to the participating processing sub-node so as to carry out standardization processing on the user identity information to be standardized by the participating processing sub-node. Therefore, a fourth checking result can be obtained, the fourth checking result can represent whether the encryption updating abnormal user identity information corresponding to the fourth checking information exists in the encryption updating abnormal user identity information, and the fourth checking result can be sent to the participating processing sub-node so that the participating processing sub-node can normalize the user identity information to be normalized according to the fourth checking result. And because the realized user information joint processing method can joint the data of all the participants, all the participants send the check information to the data check party (the execution main body of the user information joint processing) for check, and the obtained check result is sent to the participants. And checking the checking information sent by the participant through four times of checking to obtain the standard user identity information corresponding to the checking information sent by the participant. In the whole process of user information joint processing, each participant does not know user data sent by other participants, and the data corrector does not know specific data sent by each participant. Thereby improving the security of the user information. And the problem that user information joint processing cannot be carried out through plaintext data exchange under the condition that the original data of the data checking party and the data checked party are secret is solved.

The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Fig. 1 illustrates a flow 100 of some embodiments of a user information joint processing method according to the present disclosure. The user information joint processing method comprises the following steps:

Step 101, encrypting each piece of standard user identity information included in a pre-stored standard user information set and each piece of abnormal user identity information included in a pre-stored abnormal user information mapping relation set to obtain each piece of encrypted standard user identity information and each piece of encrypted abnormal user identity information, and sending the encrypted information to each participating processing sub-node so that the participating processing sub-node in each participating processing sub-node can encrypt each piece of user identity information to be normalized.

In some embodiments, an executing body (for example, a computing device) of the user information joint processing method may perform encryption processing on each standard user identity information included in a pre-stored standard user information set and each abnormal user identity information included in a pre-stored abnormal user information mapping relation set to obtain each encrypted standard user identity information and each encrypted abnormal user identity information, and send the encrypted information to each participating processing sub-node, so that the participating processing sub-node in each participating processing sub-node performs encryption processing on each user identity information to be normalized. The pre-stored standard user information in the pre-stored standard user information set can represent standard user identity information and user detail information. The user identity information may be a customer name. For example, the customer name may be a company name. The pre-stored standard user information in the pre-stored standard user information set may include standard user identity information and user detail information. The user detail information may be related information of the user corresponding to the user identity information. The user details may include, but are not limited to: user information, domain classification information, and region information are associated. The related user information may be a target company having a value-related relationship with a company corresponding to the user identity information. For example, the value correlation may be investment or holding stock. The target company may be a company corresponding to the subject of execution, a higher-level company of a company corresponding to the subject of execution, or another company having the same higher-level company as the company corresponding to the subject of execution. For example, the domain classification information may be an industry classification of a company corresponding to the user identity information. The region information may be a registration address of a company corresponding to the user identity information. The pre-stored abnormal user information mapping relation in the pre-stored abnormal user information mapping relation set may include abnormal user identity information and standard user identity information corresponding to the abnormal user identity information. The above-mentioned respective participating processing sub-nodes may characterize respective servers participating in the joint processing of user information. In practice, firstly, the executing body may adopt an MD5 encryption algorithm to encrypt each piece of standard user identity information included in the pre-stored standard user information set and each piece of abnormal user identity information included in the pre-stored abnormal user information mapping relation set, so as to obtain each piece of encrypted standard user identity information and each piece of encrypted abnormal user identity information. And then, the encryption information can be sent to each participating processing sub-node in a wired connection or wireless connection mode, so that the participating processing sub-node in each participating processing sub-node carries out encryption processing on the identity information of each user to be normalized. The encryption information may be prompt information of participating in the encryption processing of the identity information of each user to be normalized by the processing sub-node. Each of the above-mentioned respective participating processing sub-nodes comprises respective user identity information to be normalized. The above-mentioned user identity information to be normalized may be user identity information to be determined. The canonical user identity information may be a user name of the naming canonical. It should be noted that, the above standard user identity information is standard user identity information.

Step 102, in response to receiving the first verification information sent by the participating processing sub-node in each participating processing sub-node, performing verification processing on the first verification information according to the user identity information of each encryption standard to obtain a first verification result, and sending the first verification result to the participating processing sub-node.

In some embodiments, the executing body may respond to receiving the first verification information sent by the participating processing sub-node in the participating processing sub-nodes, perform verification processing on the first verification information according to the user identity information of each encryption standard to obtain a first verification result, and send the first verification result to the participating processing sub-node. The first check information may represent check information sent by the participating processing child node for the first time. The verification information can be encrypted user identity information to be normalized. The encrypted user identity information to be normalized may be user identity information to be normalized encrypted by an MD5 encryption algorithm included in the participating processing sub-node. The first verification result may represent a result after the first verification of the verification information. In practice, first, in response to receiving the first verification information sent by the participating processing sub-node in the participating processing sub-nodes, the executing body may perform verification processing on the first verification information according to the user identity information of each encryption standard in various manners to obtain a first verification result. And then, the first check result can be sent to the participating processing child nodes in a wired connection or wireless connection mode.

Optionally, before step 102, the executing body may further send preset first encryption information to the participating processing sub-node, so that the participating processing sub-node performs encryption processing on the identity information of each user to be normalized. The preset first encryption information may be a public key pair generated by an RSA encryption algorithm. The public key pair may include a first public key and a second public key. The first public key and the second public key are integers. The first public key may be a product of a first predetermined prime number and a second predetermined prime number. The first preset prime number and the second preset prime number may be different prime numbers greater than 1000. The second public key may be greater than 1 and less than a predetermined value. The preset value may be a product of a difference between the first preset prime number and 1 and a difference between the second preset prime number and 1. In practice, the executing body may send the preset first encryption information to the participating processing sub-node through a wired connection or a wireless connection.

In some optional implementations of some embodiments, in response to receiving the first check information sent by a participating processing sub-node in the participating processing sub-nodes, the executing body may perform a check process on the first check information according to the user identity information of each encryption standard to obtain a first check result:

And the first step is to encrypt the first check information according to preset second encryption information to obtain encrypted first check information. The preset second encryption information may be a private key generated by an RSA encryption algorithm. The encrypted first verification information may be first verification information encrypted by the private key.

And a second step of transmitting the encrypted first check information to the participating processing sub-node, so that the participating processing sub-node decrypts the encrypted first check information to obtain decrypted first check information. The decrypting the first verification information may be a quotient of the encrypting the first verification information and the first encrypted random number. The first encrypted random number may be obtained by encrypting a first preset random number by the participating processing node through a first public key in the first encryption information. The first preset random number may be a random number randomly generated by the participating processing child node. In practice, the executing body may send the encrypted first verification information to the participating processing child node by using a wired connection or a wireless connection.

And thirdly, encrypting the user identity information of each encryption standard according to the preset second encryption information to obtain the user identity information of each secondary encryption. The secondary encrypted user identity information may be encrypted standard user identity information encrypted by the private key.

And step four, transmitting the secondary encrypted user identity information to the participating processing sub-node so that the participating processing sub-node can determine whether the secondary encrypted user identity information matched with the decrypted first verification information exists in the secondary encrypted user identity information. In practice, the executing body may send the secondary encrypted user identity information to the participating processing child nodes by using a wired connection or a wireless connection. When the decrypted first verification information is equal to at least one piece of the secondary encrypted user identity information, it is indicated that the secondary encrypted user identity information matches the decrypted first verification information.

And fifthly, initializing a preset first check result sequence. The preset first check result sequence may represent a first check result. The initial state of the preset first check result sequence may be null. In practice, the execution body may void the preset first check result sequence, so as to initialize the preset first check result sequence.

A sixth step of executing the following steps in response to receiving the first data request information sent by the participating processing child node:

a first sub-step of generating a first random number sequence. Wherein the first random number sequence may characterize each random number. The first data request information may be an inadvertent transmission request. The above-described inadvertent transmission request may be a request sent through an inadvertent transmission protocol. The number of the first random numbers in the first random number sequence may be the same as the number of the encrypted standard user identity information in each encrypted standard user identity information. In practice, the executing body may generate the first random number sequence by adopting a random number generation algorithm.

And a second sub-step of transmitting the first random number sequence to the participating processing sub-node, so that the participating processing sub-node performs a first random number encryption process on the first random number sequence. The first random number encryption process may be to add the first preset random number to each first random number in the first random number sequence. In practice, the executing body may send the first random number sequence to the participating processing child node by using a wired connection or a wireless connection.

And a third sub-step, in response to receiving the first encrypted random number sequence sent by the participating processing sub-node, performing encryption processing on each piece of user detail information corresponding to each piece of encryption standard user identity information in the pre-stored standard user information set according to the preset second encryption information to obtain an encrypted user detail information sequence. The encrypted user detail information sequence may be each user detail information encrypted by the preset second encryption information. The first encrypted random number sequence may be obtained by adding, to each first random number in the first random number sequence, the first preset random number to the participating processing sub-node.

And a fourth sub-step of encrypting the first encrypted random number sequence according to the preset second encryption information and the first random number sequence to obtain a first twice encrypted random number sequence. The first twice-encrypted random number sequence may be an encrypted first encrypted random number sequence. In practice, first, the executing body may subtract the first random number in the first random number sequence from each first encrypted random number in the first encrypted random number sequence to obtain a first difference sequence. The first difference sequence may be each difference between each first encrypted random number and each first random number corresponding to each first encrypted random number. Then, the first difference sequence may be encrypted according to the second encryption information, to obtain a first twice-encrypted random number sequence.

And a fifth sub-step of combining the encrypted user detail information in the encrypted user detail information sequence with the first twice encrypted random number in the first twice encrypted random number sequence to obtain a first encrypted standard user information sequence. The first encryption standard user information in the first encryption standard user information sequence may be information obtained by combining the encrypted user detail information and the first twice encrypted random number. In practice, for each encrypted user detail information in the encrypted user detail information sequence, the executing body may add the encrypted user detail information to a first twice-encrypted random number having the same sequence number as the encrypted user detail information in the first twice-encrypted random number sequence, to obtain first encrypted standard user information.

And a sixth sub-step of assigning the first encryption standard user information sequence to the preset first check result sequence.

Seventh, determining the obtained preset first check result sequence as a first check result.

Step 103, in response to receiving the second check information sent by the participating processing sub-node, performing check processing on the second check information according to the encrypted abnormal user identity information to obtain a second check result, and sending the second check result to the participating processing sub-node.

In some embodiments, in response to receiving the second verification information sent by the participating processing sub-node, the executing body may perform verification processing on the second verification information according to the encrypted abnormal user identity information to obtain a second verification result, and send the second verification result to the participating processing sub-node. The second verification information may represent verification information sent by the participating processing child node for a second time. The verification information may be the encrypted user identity information to be normalized. The second verification result may represent a result after the second verification of the verification information. It should be noted that, when the second check result is null, it indicates that no canonical user identity information corresponding to the encrypted user identity information to be normalized exists in the pre-stored abnormal user information mapping relation set. In practice, first, in response to receiving the second verification information sent by the participating processing child node, the executing body may perform verification processing on the second verification information according to the encrypted abnormal user identity information in various manners to obtain a second verification result. The second check result may then be sent to the participating processing child nodes by means of a wired connection or a wireless connection.

In some optional implementations of some embodiments, in response to receiving the second verification information sent by the participating processing child nodes, the executing body may perform verification processing on the second verification information according to the encrypted abnormal user identity information to obtain a second verification result by:

and a first step of encrypting the second verification information according to the preset second encryption information to obtain encrypted second verification information. The encrypted second verification information may be second verification information encrypted by the preset second encryption information.

And a second step of transmitting the encrypted second check information to the participating processing sub-node, so that the participating processing sub-node decrypts the encrypted second check information to obtain decrypted second check information. Wherein the decrypted second verification information may be a quotient of the encrypted second verification information and a second encrypted random number. The second encrypted random number may be obtained by encrypting a second preset random number by the participating processing node through a first public key in the first encryption information. The second preset random number may be a random number randomly generated by the participating processing child node. In practice, the executing body may send the encrypted second verification information to the participating processing child node by using a wired connection or a wireless connection.

And thirdly, carrying out encryption processing on the encrypted abnormal user identity information according to the preset second encryption information to obtain the encrypted abnormal user identity information. The second encrypted abnormal user identity information may be encrypted by the second encrypted information.

And step four, transmitting the secondary encrypted abnormal user identity information to the participating processing sub-node so that the participating processing sub-node can determine whether the secondary encrypted abnormal user identity information matched with the decrypted second checking information exists in the secondary encrypted abnormal user identity information. In practice, the executing body may send the information of each secondary encrypted abnormal user identity to the participating processing child node by adopting a wired connection or a wireless connection mode. When the decrypted second verification information is equal to at least one piece of the secondarily encrypted abnormal user identity information, it is indicated that the secondarily encrypted abnormal user identity information matches the decrypted second verification information.

And fifthly, initializing a preset second checking result sequence. Wherein the predetermined second test result sequence may represent a second test result. The initial state of the preset second check result sequence may be null. In practice, the execution body may void the preset second calibration result sequence, so as to initialize the preset second calibration result sequence.

And sixthly, responding to the received second data request information sent by the participating processing child nodes, executing the following steps:

a first sub-step of generating a second random number sequence. Wherein the second random number sequence may characterize the respective random number. The second data request information may be an inadvertent transmission request. The number of second random numbers in the second random number sequence may be the same as the number of encrypted abnormal user identity information in each encrypted abnormal user identity information. In practice, the executing entity may employ a random number generation algorithm to generate the second random number sequence.

And a second sub-step of transmitting the second random number sequence to the participating processing sub-node, so that the participating processing sub-node performs a second random number encryption process on the second random number sequence. The second random number encryption process may be to add the second preset random number to each second random number in the second random number sequence. In practice, the executing entity may send the second random number sequence to the participating processing child node by using a wired connection or a wireless connection.

And a third sub-step, in response to receiving the second encrypted random number sequence sent by the participating processing sub-node, according to the preset second encrypted information, performing encryption processing on each piece of standard user identity information corresponding to each piece of encrypted abnormal user identity information in the pre-stored abnormal user information mapping relation set to obtain an encrypted standard user identity information sequence. The encrypted standard user identity information sequence may be each standard user identity information encrypted by the preset second encryption information.

In practice, in response to receiving the feedback information sent by the participating processing sub-nodes, the executing entity may determine the canonical user information corresponding to the identity information of the user to be normalized in various manners.

In some optional implementations of some embodiments, in response to receiving the feedback information sent by the participating processing sub-nodes, the executing entity may determine canonical user information corresponding to the identity information of the user to be canonical by:

The first step is to determine whether the standard user identity information or the abnormal user identity information matched with the user identity information to be normalized exists in the standard user identity information or the abnormal user identity information according to the standard user identity information and the abnormal user identity information. In practice, the executing body may determine, according to the standard user identity information and the abnormal user identity information, whether standard user identity information or abnormal user identity information matched with the user identity information to be normalized exists in the standard user identity information or the abnormal user identity information.

And secondly, extracting the characteristics of the preprocessed user identity information to be normalized to obtain a target user identity information characteristic vector. The feature vector of the target user identity information can represent the feature vector of the preprocessed user identity information to be normalized, which is obtained through feature extraction. In practice, the executing body can adopt a feature extraction model to perform feature extraction on the preprocessed user identity information to be normalized to obtain a target user identity information feature vector. The feature extraction model may be a neural network model with user identity information as input and user identity information feature vectors as output. For example, the feature extraction model may be a CNN model, a LIST model, or a BERT model, or may be a model obtained by training a combination of a CNN model, an LSTM model, and a BERT model.

And thirdly, extracting the characteristics of the standard user identity information to obtain first characteristic vectors. The first feature vectors may represent feature vectors obtained by feature extraction of the standard user identity information. In practice, the executing body may use the feature extraction model to perform feature extraction on the standard user identity information to obtain each first feature vector.

And step four, extracting the characteristics of the abnormal user identity information to obtain second characteristic vectors. The second feature vectors may represent feature vectors obtained by feature extraction of the abnormal user identity information. In practice, the executing body may use the feature extraction model to perform feature extraction on the identity information of each abnormal user to obtain each second feature vector.

And fifthly, performing feature matching on the target user identity information feature vector and each first feature vector to obtain each first matching value. Wherein each of the first matching values may represent each degree of matching between each of the first feature vectors and the target user identity information feature vector.

And seventhly, determining that the standard user identity information corresponding to the first matching value meeting the preset matching threshold condition is matched with the user identity information to be normalized in response to determining that the first matching value meeting the preset matching threshold condition exists in the first matching values. The preset matching threshold condition may be that the matching value is greater than a preset threshold. Here, the specific setting of the above-described preset threshold is not limited. The above-mentioned matching value may be the first matching value or the second matching value. In practice, in response to determining that the first matching value greater than the preset threshold exists in the first matching values, determining that standard user identity information corresponding to the first matching value greater than the preset threshold is matched with the user identity information to be normalized.

And eighth, in response to determining that no first matching value satisfying the preset matching threshold condition exists in the first matching values, determining whether a second matching value satisfying the preset matching threshold condition exists in the second matching values.

And a ninth step of determining that abnormal user identity information corresponding to the second matching value satisfying the preset matching threshold condition matches the user identity information to be normalized in response to determining that the second matching value satisfying the preset matching threshold condition exists in the second matching values.

The technical solutions described in the first to ninth steps are related to the present disclosure as an invention point of the embodiments of the present disclosure, which solves the second technical problem mentioned in the background art that the efficiency of the user information joint processing is low. Factors that lead to a low efficiency of the user information joint processing tend to be as follows: and the data required by the verification of the original data reported by the data checked party does not exist in the data checked party, and the original data reported by the data checked party is required to be subjected to the verification and normalization processing manually. If the above factors are solved, the effect of improving the efficiency of the joint processing of the user information can be achieved. To achieve this, the present disclosure introduces feature vectors for each abnormal user identity information included in a set of mapping relationships by generating each standard user identity information and pre-stored abnormal user information. And then matching the generated characteristic vectors with the characteristic vectors of the user identity information to be normalized. And finally, determining the standard user identity information corresponding to the user identity information to be standardized according to each matching result. Thus, the manual participation can be reduced while the accuracy of the determined canonical user identity information is ensured. Thereby improving the efficiency of the joint processing of the user information.

Optionally, first, in response to determining that no standard user identity information or no abnormal user identity information matching the to-be-normalized user identity information exists in the standard user identity information or the abnormal user identity information, the executing entity may further send the to-be-normalized user identity information and prompt information for determining the user identity information to a terminal device of a data processing user, so that the data processing user determines standard user information corresponding to the to-be-normalized user identity information. The prompt information for determining the user identity information may be prompt information for prompting the data processing user to confirm standard user information of the user identity information to be normalized. The data processing user can be a professional for carrying out standard management on the user identity information. The terminal device may be, but is not limited to: a mobile phone and a computer. The standard user information may characterize canonical user identity information and user detail information. The standard user information may include standard user identity information and user detail information. In practice, the executing body may adopt a wired connection or a wireless connection manner to send the user identity information to be normalized and the prompt information for determining the user identity information to the terminal device of the data processing user.

It should be noted that the wireless connection may include, but is not limited to, 3G/4G connections, wiFi connections, bluetooth connections, wiMAX connections, zigbee connections, UWB (ultra wideband) connections, and other now known or later developed wireless connection means.

Then, in response to receiving the standard user information sent by the terminal device, the received standard user information is determined as standard user information corresponding to the user identity information to be standardized.

Alternatively, first, for each pre-stored abnormal user information mapping relation included in the pre-stored abnormal user information mapping relation set, the executing body may further execute the following steps:

and determining the standard user identity information included in the pre-stored abnormal user information mapping relation as a standard user identity entity node. The entity node of the standard user identity can represent the entity node corresponding to the standard user identity information.

And secondly, determining the abnormal user identity information included in the pre-stored abnormal user information mapping relation as an abnormal user identity entity node. The entity node with abnormal user identity can represent the entity node corresponding to the abnormal user identity information.

And thirdly, determining the unique relationship as the entity relationship between the standard user identity entity node and the abnormal user identity entity node.

And fourthly, determining the standard user identity entity node, the abnormal user identity entity node and the entity relationship as a user identity relationship triplet. The user identity relationship triplets can represent entity relationships between standard user identity entity nodes and abnormal user identity entity nodes.

And then, constructing a knowledge graph corresponding to the user identity relation according to the obtained user identity relation triples. Therefore, the user can intuitively watch the association relationship between the standard user identity information and the abnormal user identity information.

And finally, storing the knowledge graph. In practice, the executing body may store the knowledge-graph in a database. Therefore, the knowledge graph of the graph structure is stored, the storage of redundant information can be reduced, and the storage space is saved.

The related content of the technical scheme is taken as an invention point of the embodiment of the disclosure, so that the technical problem mentioned in the background art is solved, and the third problem is that the data required for verification is only stored in a data verification party, more redundant data exists in a common storage mode, so that the query efficiency of the data required for verification is lower, and when each data is frequently transmitted by the verification party to be verified, the verification efficiency is lower. Factors that lead to less efficient verification tend to be as follows: because the data required by the verification is only stored in the data verification party, more redundant data exists in a common storage mode, so that the query efficiency of the data required by the verification is lower. If the above factors are solved, the effect of improving the verification efficiency can be achieved. In order to achieve the effect, the method and the device introduce a knowledge graph to store each pre-stored abnormal user information mapping relation in the pre-stored abnormal user information mapping relation set, reduce the storage of redundant data, save storage space and improve query efficiency, so that verification efficiency can be improved.

Optionally, after step 104, the executing body may update and store the knowledge graph according to the to-be-normalized user identity information and the normalized user identity information. In practice, first, the executing entity may determine the to-be-normalized user identity information as an abnormal user identity entity node. The canonical user identity information described above may then be determined as a canonical user identity entity node. The unique relationship may then be determined as a node relationship between the abnormal user identity entity node and the canonical user identity entity node.

Wherein, the updating user information in the updating user information set may include updating standard user identity information. The updating abnormal user information mapping relation in the updating abnormal user information mapping relation set may include updating abnormal user identity information and updating standard user identity information corresponding to the updating abnormal user identity information. In practice, the executing body may update the pre-stored standard user information set and the pre-stored abnormal user information mapping relation set according to the user identity information to be normalized and the normalized user information corresponding to the user identity information to be normalized, so as to obtain an updated user information set and an updated abnormal user information mapping relation set:

In the first step, in response to determining that the standard user information is standard user information, standard user identity information and user detail information included in the standard user information are added to the pre-stored standard user information set, so that the pre-stored standard user information set is updated to obtain an updated user information set.

And a second step of determining the user identity information to be normalized and the standard user identity information as abnormal user information mapping relations in response to determining the normalized user information as standard user identity information, and adding the determined abnormal user information mapping relations to the pre-stored abnormal user information mapping relation set to update the pre-stored abnormal user information mapping relation set to obtain an updated abnormal user information mapping relation set.

The above-mentioned each encrypted updated standard user identity information may be each encrypted updated standard user identity information. The above-mentioned each encrypted updated abnormal user identity information may be each encrypted updated abnormal user identity information. In practice, the executing body may adopt an MD5 encryption algorithm to encrypt each piece of updated standard user identity information included in the updated user information set and each piece of updated abnormal user identity information included in the updated abnormal user information mapping relation set, so as to obtain each piece of encrypted updated standard user identity information and each piece of encrypted updated abnormal user identity information.
