Developed foundational data privacy infrastructure for the ApsaraDB/PolarDB-for-PostgreSQL repository by designing and implementing a comprehensive data masking framework. Leveraging C programming and PostgreSQL extension development, the work introduced policy-driven masking at the database object and column level, including mechanisms for binding and unbinding masking labels and configuring masking operators. The solution incorporated regex-based masking parameters and a suite of masking functions for sensitive text data such as credit cards and emails. This approach enabled scalable, policy-based privacy controls, supporting compliance and secure analytics across production workloads while establishing a robust foundation for future expansion of data governance capabilities.
