Unique: Attribute-based access control (ABAC) that evaluates policies at query time rather than pre-computing masked datasets, enabling dynamic policy changes without data reprocessing. Supports multiple masking strategies (tokenization, hashing, partial redaction) applied conditionally based on role attributes.

vs others: More flexible than role-based access control (RBAC) alone because it can express complex policies like 'show full SSN only to HR and compliance, show last 4 digits to managers, redact entirely for contractors.' Faster than row-level security in databases because policies are evaluated centrally rather than distributed across database engines.
