The user data is not only used in the internal controllable system, but also used in a third party system of a specific service scene, so that the user data in the third party system is also required to be destroyed when the user data is destroyed internally. At present, when user data in a third party system is destroyed, a commonly adopted method for issuing an destroyed data command is as follows: and for each data destruction task, after the data destruction task is processed, issuing a data destruction instruction to a third party system.
However, the inventors found that when the above manner is adopted to issue the destruction data instruction, there are often the following technical problems:
first, when the destroyed data volume is large, the sending efficiency of the high concurrency instruction is low, so that the instruction is blocked more.
Secondly, when the third party system identifies a data destroying instruction, the third party system can determine that the data is abnormal and the data is not destroyed, so that the third party system falsely destroys the data more times.
Thirdly, when identifying the sensitive data in the user data, the sensitive data is generally identified through a preset sensitive data identification rule, and when the user data contains unstructured information, the sensitive data cannot be identified, so that more unstructured sensitive data are leaked.

And a second step of dividing each first user data group corresponding to the target system information from the first user data group set as a second user data group set. And the system information corresponding to each second user data group in the second user data group set is the target system information.
And thirdly, according to the second user data set, carrying out block query processing on each second data downlink message in the second data downlink message set to obtain each downlink user data set.
Finally, each of the obtained sets of delivery user data may be determined as a set of delivery user data sets. Therefore, the first user data set can be divided from the dimension of the system information, and the query can be further partitioned on the basis of the second user data set, so that the query efficiency is improved.
In some optional implementations of some embodiments, the executing body may perform a block query process on each second data downlink message in the second data downlink message group according to the second user data group set to obtain each downlink user data group by:
and dividing the second data downloading information corresponding to the same user account information in the second data downloading information group into one group to obtain a third data downloading information group set.
The second step, for each third data transmission information group in the third data transmission information group set, executing the following steps:
And a first sub-step of determining the user account information corresponding to the third data issuing information group as target user account information.
And a second sub-step of dividing each second user data group corresponding to the target user account information from the second user data group set as a third user data group set.

Therefore, the third user data set can be divided from the dimension of the data issuing type, so that the third user data set can be divided to the issuing user data set which finally needs to be inquired, and the inquiring efficiency is improved.
Step 1023, for each of the user data sets, responding to the determination that the first data issuing information corresponding to the user data set satisfies the preset data destruction condition, and destroying the user data set stored by the user data application end according to the user data set.
In some embodiments, for each of the set of sending user data sets, the executing body may perform destruction processing on the sending user data set stored in the user data application according to the sending user data set in response to determining that the first data sending information corresponding to the sending user data set meets a preset data destruction condition. The preset data destruction condition may be that a data transmission type included in the first data transmission information is a destruction type. The user data application may be a server corresponding to system information included in the first data downloading information. The user data application end stores the issuing user data group.
In some optional implementations of some embodiments, the executing body may, in response to determining that the data delivery type corresponding to the first data delivery information is a destruction type, execute, for each of the delivery user data groups, the following steps:
the first step is to encrypt the second key through the first key to obtain an encrypted second key. The first key may be a key of user account information corresponding to the issued user data, which is randomly generated. The second key may be a key randomly generated corresponding to a login validity period of the user account information included in the first data transfer information, or a key randomly generated corresponding to a token validity period of the system information included in the first data transfer information. That is, the second key is valid for the login validity period or the token validity period. As an example, the executing entity may encrypt the second key with the first key by using the SM2 algorithm, to obtain an encrypted second key.
And secondly, determining sensitive user data in the issuing user data.
And thirdly, encrypting the sensitive user data in the issuing user data through the encryption second key to obtain encrypted issuing user data.

That is, the third key is valid for the login validity period or the token validity period. As an example, the executing body may perform salt hash processing on the sensitive user data by using an SM3 algorithm to obtain verification information. The verification information is valid in the login validity period or the token validity period.
And fifthly, checking the sensitive user data according to the checking information and the information to be checked corresponding to the sensitive user data to obtain a checking result. The information to be verified may be verification information of the sensitive user data generated according to the third key, which is sent by a data source (client). In practice, the executing body may generate a verification result representing that the verification is passed in response to determining that the verification information is the same as the information to be verified. The execution body may further generate a verification result indicating that the verification is not passed in response to determining that the verification information is different from the information to be verified.
And sixthly, transmitting the encrypted issuing user data and the data destruction information to the user data application end in response to the fact that the verification result representation passes verification, so that the user data application end destroys the stored issuing user data according to the data destruction information. The first data downloading information corresponding to the user data comprises the data destruction information. The data destruction information may be information representing a destruction mode. For example, the data destruction information may include, but is not limited to: destroying time.

And eighth, in response to determining that the destruction check result represents that the destruction is not performed, performing a dark-pin destruction process on the issued user data stored by the user data application terminal.
And ninth, in response to determining that the verification result represents that the verification is not passed, sending tamper information corresponding to the issued user data to a target terminal. The tamper information may be information indicating that the sending user data is tampered. The tamper information may include a data identifier of the issuing user data. The target terminal may be a terminal that handles user data anomalies.
Optionally, the foregoing user data may include user-defined description information. The user-defined description information may be unstructured text information which is self-described by the user. For example, the user-defined description information may be a personal information profile of the user.
In some optional implementations of some embodiments, the executing entity may determine the sensitive user data in the outgoing user data by:
And determining each data meeting the preset sensitive field condition in the issued user data as each sensitive user information. The preset sensitive field condition may be that a field corresponding to data included in the user data belongs to a sensitive field. The sensitive field may be preset.
And secondly, constructing a grammar tree corresponding to the user-defined description information according to the user-defined description information. In practice, the execution body may construct an abstract syntax tree corresponding to the user-defined description information.
And thirdly, extracting a custom description word set meeting preset grammar conditions from the grammar tree. The user-defined description information comprises the user-defined description word set. The preset grammar condition may be that sentence components of the text corresponding to the node are subject, object or list. In practice, the execution body may extract, from the syntax tree, each text satisfying a preset syntax condition as a custom description word set.
And fourthly, inputting the custom description word set into a pre-trained word class recognition model to obtain a word class set. The word class in the word class set corresponds to the custom description word in the custom description word set. The word-class recognition model may be a neural network model for recognizing word classes of words. The part of speech may be the semantic type to which the term belongs. For example, the word class of "A city B district C street" may be an address class. The term of "18 years" may be an age category. The word class recognition model comprises a coding layer, an interaction layer, an aggregation layer and an output layer.
And fifthly, selecting the custom description words with the corresponding word classes meeting the preset sensitive word class conditions from the custom description word set as sensitive user information. The preset sensitive word class condition may be that the word class belongs to a sensitive word class. The sensitive word class may be predetermined. For example, sensitive word classes may include, but are not limited to: address class, name class, age class.
And sixthly, determining each piece of determined sensitive user information as sensitive user data.
The first step-the sixth step are taken as an invention point of the embodiment of the present disclosure, and solve the third technical problem mentioned in the background art, when sensitive data in user data is identified, the sensitive data is generally identified by a preset sensitive data identification rule, and when unstructured information is included in the user data, the sensitive data cannot be identified, so that more unstructured sensitive data is leaked. Factors that lead to more unstructured sensitive data leakage tend to be as follows: when the sensitive data in the user data is identified, the sensitive data is usually identified through a preset sensitive data identification rule, and when unstructured information is contained in the user data, the sensitive data cannot be identified. If the above factors are solved, the effect of reducing unstructured sensitive data leakage can be achieved. To achieve this, the present disclosure first extracts a custom description word set from a constructed grammar tree of user-custom description information. The word class of each custom description word is then identified by a pre-trained word class identification model to determine whether the custom description word is sensitive. Thereby, the automatic identification of sensitive data in unstructured information can be realized. Thereby reducing unstructured sensitive data leakage.
In some optional implementations of some embodiments, the executing body may perform destruction check on the issued user data at the user data application end, to obtain a destruction check result:
the first step, the data result corresponding to the data identifier is obtained from the user data application terminal through the data identifier corresponding to the issued user data. In practice, the executing body may acquire, from the user data application end, user data with a corresponding data identifier that is the same as the data identifier of the sending user data as a data result.
And secondly, generating a destroying verification result representing destroyed in response to the fact that the data result is empty.
And thirdly, generating a destroying check result representing undestroyed state in response to the fact that the data result comprises user data. Therefore, whether the user data application end destroys the user data to be destroyed can be determined in advance.
In some optional implementations of some embodiments, the executing entity may perform a blackout process on the delivered user data stored by the user data application end by:
first, generating updated user data corresponding to the issued user data according to the issued user data. The updated user data comprises first updated user data, second updated user data and data identifiers corresponding to the issued user data. In practice, the executing body may randomly generate, as the initial updated user data, user data different from the issued user data according to the data type of the issued user data. The initial updated user data is the same as the data type and data representation of the issued user data. For example, the above-mentioned user data may be a cell phone number of 11 bits. The initial update user data is also an 11-bit cell phone number. Then, the initial updated user data may be split into first updated user data and second updated user data according to a preset splitting manner. Here, the specific setting of the preset splitting manner is not limited. For example, when the initial update user data is a mobile phone number of 11 bits, the preset splitting manner may be a manner of splitting the initial update user data into 7 bits+4 bits of numbers. The first 7 digits may be the first updated user data. The last 4 digits may be used as the second updated user data. Then, the first updated user data, the second updated user data, and the data identifier corresponding to the delivery user data may be combined into updated user data corresponding to the delivery user data.
And a second step of encrypting the first updated user data and the second updated user data included in the updated user data according to a fourth key to obtain encrypted updated data, wherein the encrypted updated data includes encrypted first updated user data, encrypted second updated user data and the data identifier. The fourth key may be a randomly generated key. In practice, the executing body may encrypt the first update user data and the second update user data included in the update user data by using an SM4 algorithm through a fourth key, so as to obtain encrypted update data.
And a third step of transmitting the encrypted update data, the fourth key, and the data update information to the user data application, so that the user data application decrypts the encrypted first update user data included in the encrypted update data by the fourth key, updates the stored first update user data included in the sending user data to the decrypted first update user data, and so that the user data application decrypts the encrypted second update user data included in the encrypted update data by the fourth key and the decrypted first update user data, generates a fifth key, decrypts the encrypted second update user data included in the sending user data by the fifth key, and updates the stored second update user data included in the sending user data to the decrypted second update user data. The fifth key may be a key updated by the user data application end based on the fourth key by using a variable cipher device according to the changed first updated user data.
The first step-the fourth step are taken as an invention point of the embodiment of the disclosure, so that the technical problem mentioned in the background art is solved, and when the third party system recognizes the data destroying instruction, the data abnormality can be determined without data destruction, and the number of times of false data destroying of the third party system is more. Factors that cause the third party system to falsely destroy data more often are as follows: when the third party system recognizes the data destroying instruction, the data abnormality can be determined without data destruction. If the above factors are solved, the effect of reducing the number of times of false destroying data by the third party system can be achieved. In order to achieve the effect, after the user data application end is confirmed in advance that the issuing user data is not destroyed, the method and the device send encrypted updating user data for updating the issuing user data to the user data application end, so that the user data application end updates the issuing user data to be destroyed into updating user data. Meanwhile, the encrypted updated user data comprises two sections of data, so that a sectional decryption mode is needed when the user data application end decrypts the encrypted updated user data. Thus, the user data application end can update the user data in a segmented way. And further, the user data application end can be prevented from finding abnormal data replacement in advance to a certain extent without updating. Thereby reducing the number of times of false data destruction of the third party system.
The above embodiments of the present disclosure have the following advantageous effects: by the user data destruction method of some embodiments of the present disclosure, processing efficiency of data issuing information when user data is destroyed is improved, and blocking of the data issuing information is reduced. In some embodiments of the present disclosure, first, in response to receiving each data transmission information, data transmission information corresponding to the same data type is divided into the same data transmission information groups, and each data transmission information group is obtained as a first data transmission information group set. Thus, the data transmission information to be processed can be grouped according to the data type in advance. Then, for each first data distribution information group in the first data distribution information group set, the following steps are executed: determining data processing channel information corresponding to the data types according to the data types corresponding to the first data issuing information group, so as to obtain each user data group corresponding to the data types as a first user data group set through each data processing channel corresponding to the data processing channel information. Therefore, the data processing channels can be allocated to the first data issuing information groups according to the data types corresponding to the first data issuing information groups, so that the first data issuing information in the first data issuing information groups is processed through the allocated data processing channels. And secondly, according to the first user data group set, carrying out block query processing on each first data downlink message in the first data downlink message group to obtain a downlink user data group set. Wherein, the sending user data group in the sending user data group set corresponds to the first data sending information in the first data sending information group. Thus, the first data descending information belonging to the same division type can be intensively processed, and the sequential processing of the first data descending information can be avoided. And thirdly, for each of the user data sets, responding to the fact that the first data issuing information corresponding to the user data sets meets the preset data destruction condition, and destroying the user data sets stored by the user data application end according to the user data sets. Wherein the user data application end stores the issuing user data group. Therefore, when the data issuing information characterizes that the corresponding issuing user data group in the third party system needs to be destroyed, the issuing user data group stored in the user data application end storing the issuing user data group can be destroyed. And before destroying the user data, dividing each data descending information, so that each data descending information can be divided into each data processing channel for centralized processing according to the data type corresponding to each data descending information. And because the first data descending information belonging to the same division type can be processed in a centralized way, the sequential processing of the first data descending information can be avoided. And further, the processing efficiency of data transmission information when the user data is destroyed is improved, and the blockage of the data transmission information is reduced.
