Dynamic Data Masking (DDM) is a data security product tailored to meet users' needs for database security management and control. It mainly addresses the challenges of permission control and data masking during access by operation and maintenance (O&M) personnel, business staff, and third-party users, providing distinct masked data displays based on the permissions of the accessing users. This ensures the credibility of user identities and the controllability of accessed content. Widely deployed in industries including government, healthcare, finance, and others, this system protects sensitive data assets from leakage while meeting the security requirement that users can access and utilize the data without directly viewing its raw sensitive content.
