data masking

Data masking is a technique used to alienate or anonymize data

. Data masking is characterized by the fact that, in contrast to encryption

, it works with fictitious data instead of the original data, and that the data is readable. Often the data is corporate, production or personal data. Data masking is about detecting and preventing data leakage and data loss, it is about Data Leakage Protection (DLP) or Data Loss Prevention (DLP). This testing procedure uses fictitious data that is chosen to functionally accomplish the task. This means that the data format and the functional relationships correspond to the realistic model.
