data masking
Data masking is a technique used to protect sensitive information by replacing it with fictional but realistic data. This process ensures that the original data remains confidential while still allowing users to work with a version that resembles the real data. For example, a person's name might be changed to a generic name, while keeping the format intact.
This method is commonly used in software development, testing, and data analysis to prevent unauthorized access to sensitive information, such as personal identification numbers or financial records. By using masked data, organizations can maintain privacy and comply with regulations while still performing necessary tasks.
