Example
Data masking is useful when the structure of the data needs to remain so that the data can be used for testing or training. For example, a phone number such as 000-000-000 may pass validations. In this example, an encrypted phone number or null phone number may cause application errors.Reversibility
Data masking seeks to create outputs that are irreversible. Techniques such as encryption are difficult to reverse but often change the structure of data such that it no longer passes validations in applications. Data masking may use algorithms for shuffling and substitution that are designed to be difficult to reverse but maintain strict data formats.| Overview: Data Masking | ||
