Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and more specifically, to a test data extraction method and system. Background Art

[0002] The data used in information system testing operations is currently mainly selected from the production system, then decrypted and stored in the intermediate server, then anonymized and imported into the test database, or selected from the production system, then decrypted and anonymized, then stored in the intermediate server, and then imported into the test database. Specifically, there are usually the following two operation methods: (I) The operator connects the operating platform to the production database, selects the table and field to be desensitized on the operating platform, selects the desensitization algorithm to be used (such as shielding and replacement), selects the number of data rows, and if the field is stored in encrypted form, it needs to be decrypted first and then desensitized, and the desensitized data file is generated on the intermediate server; (ii) The operator logs in to the production database on the bastion host of the production environment. If the fields that need to be desensitized are stored in encrypted form, the fields that need to be desensitized are first decrypted, and then the data is desensitized using internal or external functions of the database, SQL statements, or third-party processing tools. The desensitized data file is generated on the intermediate server, and then the desensitized data file on the intermediate server is transferred to the test server and then imported into the test database.

[0003] However, in the above existing methods, since operators directly operate the database, they can access the production and / or test data before desensitization, which poses a risk of data leakage. Summary of the invention

[0013] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0014] Example 1 This embodiment provides a test data extraction method, referring to FIG1 , comprising: Display the development and operation and maintenance interactive interface; In response to the authorization triggering operation of the second user (such as an administrator or a project manager) on the data extraction task sheet creation request for the project to be managed in the development and operation and maintenance interactive interface, a data extraction task sheet is generated; wherein the data extraction task sheet creation request is used to request that the first user (such as a tester) have the extraction operation authority for the production data corresponding to the target resource configuration information, the second user has the authorization authority to associate the first user with the production data, and the target resource configuration information is confirmed from the candidate resource configuration information for the project to be managed; In response to the first user's triggering operation on the test data management control included in the development and operation and maintenance interactive interface, displaying the test data management interactive interface corresponding to the test data management control; wherein the test data management interactive interface is used to display the candidate test database instance, as well as the data extraction task list and the corresponding target resource configuration information; In response to the first user confirming the execution of the data extraction task order and confirming the trigger operation of the target test database instance from the candidate test database instance, the production data is extracted and desensitized according to the target resource configuration information to obtain the test data and import it into the target test database instance.

[0015] In this embodiment, a data extraction task sheet is generated by responding to the authorization trigger operation of the second person, and the first person confirms the target test database instance and confirms the execution of the data extraction task sheet, thereby extracting the production data for desensitization, and importing the desensitized test data into the target test database instance, thereby avoiding the operator's direct operation of the database (especially the production database) and the generation of intermediate data, effectively reducing the risk of data leakage, and solving both the risk of data leakage during data transmission and the risk of data leakage in subsequent data use.

[0016] Those skilled in the art should understand that based on the implementation of the method, the entire chain of research and development, testing and security can be opened up.

[0017] In some preferred embodiments, referring to FIG. 2 , the process of generating a data extraction task order creation request includes: In response to the first user's triggering operation on the resource management control included in the development and operation and maintenance interactive interface, displaying a resource management interactive interface corresponding to the resource management control; wherein the resource management interactive interface is used to display candidate resource configuration information of the project to be managed; In response to the trigger operation of the first user confirming the target resource configuration information from the candidate resource configuration information, displaying a candidate desensitization algorithm interaction interface; wherein the candidate desensitization algorithm interaction interface is used to display candidate desensitization operation algorithms, and the candidate desensitization operation algorithms are used to indicate the desensitization operation for the production data corresponding to the target resource configuration information; In response to the first user confirming the triggering operation of the target desensitizing operation algorithm from the candidate desensitizing operation algorithms, the data extraction task order creation request is generated.

[0018] It should be noted that the static desensitization method is adopted in the above preferred embodiment. The first user selects various required resources, such as database tables, data fields, etc., from the candidate resource configuration information for the test project, and then selects the appropriate target desensitization operation algorithm, and finally forms a data extraction task order creation request and submits it to the second user for authorization.

[0019] In some optional embodiments, the candidate resource configuration information includes a production database instance and data volume associated with the project to be managed, and at least one of a database table and a data field.

[0020] In some specific implementation processes, when selecting a production database instance, priority is given to selecting a disaster recovery production database or a backup machine of a production database.

[0021] Furthermore, the database table and the data fields are determined according to a project requirement analysis document associated with the project to be managed.

[0022] Those skilled in the art should understand that the data required for testing (database tables and data fields) are obtained from the project requirement analysis document, which ensures the relevance and integrity of the required data and ensures that too much production data is not extracted.

[0023] Those skilled in the art should understand that, during the project requirements analysis phase, R&D personnel often obtain the database tables and fields required for the project to be managed based on the business requirements analysis, and register them in the requirements analysis document, and record them in the test data information table (including database tables and fields) configured in the candidate resource configuration information. Therefore, by reading the requirements analysis document and / or reading the test data information table in the candidate resource configuration information and through operations such as selection and confirmation in the resource management interactive interface, the database tables, data fields, data sensitivity and other information involved in the production data of the project to be managed can be automatically obtained. Based on this, some of the results formed in the requirements analysis in the R&D phase can be directly selected in the testing phase and other downstream phases, which improves the efficiency of test data generation and the data availability of the entire process.

[0024] In some specific implementations, the requirement analysis document is formed by displaying a requirement form template to a specific user (such as a product manager role user) and receiving input from the specific user on the requirement form template. Based on the requirement analysis document, an iterative version log and version change content related to the requirement analysis document are formed, and other users (such as tester role users) can extract data more accurately for testing based on the iterative version log and the version change content.

[0025] In other specific implementation processes, a requirement creation interface with controls such as addition, modification, deletion, annotation, and sensitivity level setting is displayed to specific users, and input from specific users is received based on an interactive view, and finally a requirement analysis document is generated based on the formed interactive form.

[0026] Furthermore, the method further comprises: The data sensitivity of each of the database tables and / or the data fields is determined according to the project requirement analysis document, and sensitive information prompts are displayed on the resource management interactive interface according to a preset classification and grading strategy.

[0027] In some optional embodiments, the method further comprises: Before extracting the production data for desensitization according to the target resource configuration information, obtaining a decryption key associated with the production data and performing a decryption operation on the production data; and / or, After the production data is desensitized and before it is stored in the target test database instance, an encryption key corresponding to the decryption key is obtained to encrypt the test data.

[0028] In some specific implementation processes, the decryption keys required for decrypting production data and the encryption keys required for encrypting test data are managed by a third user (such as an information security manager) (including key import, association, name definition, etc.) to prevent key leakage, and other personnel can only choose to use them; more specifically, the third user triggers the display of the key management interface based on the data encryption and decryption key management controls contained in the development and operation interface; the key management interface is used to display key operation controls (such as key import controls, key deletion controls, key association controls, etc.) and a list of currently available keys.

[0029] It should be noted that, since information security requires that sensitive data must be encrypted and stored in the production database, and since the test version of the information system needs to be consistent with the production version of the production environment, the original sensitive data in the test data also needs to be encrypted and stored in the test database, and the encryption and decryption algorithms and keys of these encrypted sensitive test data are also consistent with the production environment. Based on this, in the above embodiment, non-designated users (such as the first user who is not an information security management user) cannot access sensitive files (such as encryption and decryption keys) and sensitive data (such as production data and / or test data before decryption and desensitization), so that sensitive data does not fall to the ground.

[0030] In some specific implementations, the method is implemented by a computer device, and the intermediate data generated by the implementation of the method is stored in the memory of the computer device; after the implementation of the method, the intermediate data is cleared; In some other specific implementation processes, the method is implemented through a computer system, the intermediate data generated by the implementation of the method is stored on the hard disk of the computer device, and the access rights to the intermediate data are managed by a file management system installed on the computer device; after the implementation of the method, the intermediate data is cleared.

[0031] In some preferred embodiments, the test data management interactive interface is further provided with a historical data management control; The method further comprises: In response to the triggering operation of the history data management control by the first user, a test data generation history management interface is displayed; the test data generation history management interface is used to display a test data generation history list, the test data generation history list includes test data items and corresponding current retention status information; wherein the current retention status information is used to indicate whether the corresponding test data item is cleared; the test data item that has not been cleared is bound to a data belonging test item viewing control; In response to the first user's triggering operation on the data attribution test item viewing control, data attribution test item information is displayed.

[0032] In some optional embodiments, the test data items that have not been cleared are bound to a data clearing application control; the test data management interactive interface is also used to display a data clearing task list; The method further comprises: In response to the triggering operation of the data clearing application control by the first user, creating a data clearing task sheet creation request for the corresponding test data pointed to by the test data item; In response to the second user's authorization triggering operation on the data clearing task order creation request, generating a data clearing task order; In response to the first user confirming in the test data management interactive interface to execute the triggering operation of the data clearing task list, obtaining the target resource configuration information and the target test database instance associated with the test data corresponding to the data clearing task list, and clearing the corresponding test data from the target test database instance according to the target resource configuration information; After the clearing is completed, the current retention status information of the test data item is updated, and the corresponding data clearing application control is unbound.
