Fig. 1 illustrates a flow diagram of a method for data desensitization based on database virtualization, according to an aspect of the present application, the method comprising: step S11-step S13, wherein, step S11 is to backup the database data and to take a snapshot for the backed-up data; step S12, virtualizing the database according to the time point of snapshot 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 rapid preparation of the database data and the desensitization of the virtual library are realized, and the problems of complex data preparation and long time consumption after desensitization failure are rapidly solved.
Specifically, in step S11, database data is backed up, and the backed-up data is snapshot; the database is backed up, the data in the database is backed up, and snapshot operation is performed on the backed-up data, so that a data source of the database virtualization instance is provided.
Specifically, in step S12, virtualizing the database according to the time point at which the snapshot is performed, to obtain a virtual database; the database is virtualized according to the created snapshot time point, and the obtained virtual database is consistent with the database data corresponding to the snapshot time point, so that the virtual database also has data, the original database is not operated any more when desensitization is performed, and the virtual database can be operated.
Specifically, in step S13, a desensitization operation is performed on the data in the virtual database, resulting in a desensitization result. The virtual database provides database data virtualized for the database, desensitization operation is carried out on the data in the virtual database, data deformation is carried out on certain sensitive information through desensitization rules, accordingly, reliable protection of sensitive private data is achieved, desensitization results are obtained after desensitization operation is carried out, and then the desensitization results are used for processing the virtual database, for example, whether the virtual database is recovered or not is judged.
In an embodiment of the present application, in step S11, the database data is backed up periodically, the backed-up data is snapshot periodically or manually, and the created snapshot time point is recorded. The database data is backed up at regular time, and the backup data is subjected to timed snapshot or manual snapshot, for example, a snapshot one is created at 12 minutes and 12 seconds at 12 times of 1 month, 5 days and 12 days in 2021 year, a snapshot time point can be selected to create a virtualized database instance during recovery, the created virtualized database data is the data during creation of the snapshot one, and the database backup snapshot can create periodic snapshots and manually create snapshots as required and according to time.
