FIG. 1 illustrates a flow diagram of a method for database virtualization-based data desensitization provided in accordance with an aspect of the present application, the method comprising: step S11 to step S13, wherein in step S11, database data is backed up, and snapshot is carried out on the backed up data; step S12, virtualizing a database according to the snapshot time point to obtain a virtual database; and step S13, performing desensitization operation on the data in the virtual database to obtain a desensitization result. Therefore, the quick preparation of database data and the desensitization of the virtual library are realized, and the problems of complicated data preparation and long time consumption after the failure of desensitization are quickly solved.
Specifically, in step S11, database data is backed up, and snapshot is performed on the backed up data; and backing up the database, backing up the data therein, and performing snapshot operation on the backed-up data, thereby providing a data source of the database virtualization instance.
Specifically, in step S12, the database is virtualized according to the time point of snapshot, and a virtual database is obtained; the virtual database is virtualized according to the time point of the created snapshot, and the obtained data of the virtual database is consistent with the data of the database corresponding to the time point of the snapshot, so that the virtual database also has data, the original database is not operated when the desensitization is carried out, and the virtual database can be operated.
Specifically, in step S13, a desensitization operation is performed on the data in the virtual database, so as to obtain a desensitization result. The virtual database provides a database data virtualized by the database, the data in the virtual database is subjected to desensitization operation, certain sensitive information is subjected to data deformation through a desensitization rule, so that the sensitive privacy data is reliably protected, a desensitization result is obtained after the desensitization operation is performed, and the virtual database is further processed by the desensitization result, such as whether the virtual database is recovered or not.
In an embodiment of the present application, in step S11, database data is backed up regularly, and the backed up data is snapshot periodically or manually, and the created snapshot time point is recorded. And if the snapshot 1 is created 12 minutes and 12 seconds at the time of 12 days of 2021, 1 month and 5, the virtualized database instance can be created at the time of snapshot time point during recovery, the created virtualized database data is the data at the time of snapshot one creation, and the database backup snapshot can be used for creating periodic snapshots and manually creating snapshots according to the needs and time.
In step S12, one or more database instances are virtualized according to the created snapshot time point, where the data included in the instance includes the data in the database corresponding to the created snapshot time point. Here, according to the created snapshot time point virtualized database instance, the virtualized database instance contains data information in the database when the snapshot is created time point, and the virtual database can quickly create one or more virtual databases according to the snapshot data, so that complicated operation and long time consumption required by common physical recovery are avoided. For example, a virtual database I and a virtual database II are created according to the snapshot I, the data in the virtual database I and the virtual database II are database data of a snapshot time point, when desensitization is carried out, only the virtual database I or the virtual database II is connected to desensitize the virtual database data, and the virtual database is provided for a user after the desensitization is finished.
In one embodiment of the present application, in step S13, the data in the virtual database is subjected to masked desensitization or simulated desensitization. Here, the data in the virtual database is masked or simulated desensitized, such as masking the desensitized name: ABC, a after desensitization, or DEF after simulated desensitization ABC, the desensitization rules may be used to generate names, to generate organization names, to generate random identification numbers, etc., where the manner of desensitization rules includes, but is not limited to, the examples described above.
In an embodiment of the present application, after desensitizing the data in the virtual database to obtain a desensitization result, if the desensitization result is successful in desensitizing the data, providing the virtual database to a user for testing; and if the desensitization result is that the data desensitization fails, recycling the virtual database. Here, if the data desensitization is successful, the virtual database is provided for the user to test, and if the desensitization fails, the virtual database only needs to be recovered.
Then, after recovering the virtual database, re-virtualizing the database according to the snapshot time point to obtain a new virtual database; and adjusting a desensitization strategy to carry out desensitization operation on the new virtual database again. And recovering the virtual database with desensitization failure, and re-creating the virtual database with virtualized snapshot points, wherein when the desensitization process fails, recovering the virtual database I, and re-creating the virtual database II according to the snapshot I, wherein the data in the virtual database II is the same as the data in the virtual database I, and the data are the data when the snapshot I is created. The desensitization strategy is adjusted to desensitize the second virtual database again; therefore, the method can quickly create and destroy, can provide quick preparation work of desensitizing failure database data through virtualization of the database, and provides a complete set of brand new virtual library for desensitizing programs.
Wherein said adjusting a desensitization strategy comprises: and generating a random address desensitization rule, and adjusting a desensitization strategy according to the desensitization result of the first desensitization operation and the generated random address desensitization rule. Here, the first desensitization operation refers to a desensitization operation performed on data in the virtual database created for the first time, and after the failure of the first desensitization operation, the virtual database created for the first time is reclaimed, a new virtual database is created again, a random address desensitization rule is generated, for example, if five-level address information is selected when desensitizing for the first time, the five-level address of the town village in city and county is saved, at this time, the generated address length may exceed the range indicated by the database field, the method can fail in desensitization, so that the desensitization strategy of the second desensitization operation is reselected according to the desensitization result and the generated random address desensitization rule, for example, the third-level address such as the third-level address of the province, the city and county and the like is selected to be generated, the problem that the length of the generated address is overlong is solved, the desensitization operation is performed on the newly created virtual database according to the adjusted desensitization strategy, and the problems that data preparation is complicated and time-consuming is long after the desensitization failure are rapidly solved.
In a specific embodiment of the present application, as shown in fig. 2, a database data backup and a database snapshot are performed, when the snapshot is completed, a virtual database instance is created according to the database snapshot, a database virtualized database can be provided, when the virtualized database is desensitized, the database data can be directly provided for a user to test and use after the desensitization operation is successful, when the desensitization operation fails, the virtual database is recovered, the virtual database providing a data can be rapidly provided for the desensitization program for desensitizing by performing the virtualization creation operation on the database snapshot again, and when the user completes the use, the newly created virtual database instance is recovered, thereby completing the recovery of the data.
