Data Masking Overview

DSC supports static data masking and dynamic data masking. You can configure masking rules for specified data assets to implement static masking or use the API for dynamic data masking to implement dynamic data masking, ensuring that sensitive information is not disclosed. Masking Algorithms and Application Scenarios lists the data masking algorithms supported by DSC.

Static data masking: DSC can help mask a large amount of data at one time based on the configured data masking rules. Static data masking is used when sensitive data in the production environment is delivered to the development, testing, or external environment for development and testing and data sharing and research. You can create an data masking task on the DSC console to quickly mask sensitive data in databases and big data assets.

Dynamic data masking: DSC provides dynamic data masking APIs to mask the data accessed from the external systems. Dynamic data masking applies to scenarios where data is queried from the external system, such as production applications, data exchange, O&M applications, and marketing. For details, see API for dynamic data masking.
