Data masking

Definition

Data masking is the process of obscuring specific data within a database to protect sensitive information from unauthorized access. It serves to safeguard personal identifiable information (PII), financial data, and other confidential information while still allowing for data analysis and use in development environments. By replacing sensitive data with fictional but realistic values, organizations can maintain privacy and comply with regulations related to data protection.
