In the era of big data, protecting sensitive information through static and dynamic data masking techniques—such as nullification, randomization, substitution, symmetric encryption, averaging, and offset—ensures data security while preserving usability for development, testing, and analytics.
This article explains data masking, its importance for protecting sensitive information, and details both static and dynamic masking methods—including nullification, randomization, substitution, symmetric encryption, mean value, and offset rounding—along with practical examples and implementation considerations.
Data masking, also known as data desensitization, transforms sensitive information such as phone numbers and ID numbers using static and dynamic methods—including truncation, randomization, replacement, encryption, and averaging—to prevent privacy breaches while preserving data utility for testing, analysis, and production environments.
