Deterministic Token Based Pii Replacement

via “deterministic token-based pii replacement”

Unique: Uses deterministic, type-labeled tokens ([NAME_1], [EMAIL_1]) instead of random hashes or UUIDs, making the masking structure transparent and human-readable. This design prioritizes usability and consistency over cryptographic security, allowing users to manually verify masking and maintain context across multi-turn conversations.

vs others: More transparent and user-friendly than opaque hashing or random token generation, but less secure because the deterministic structure and type labels reveal information about the masked data and make inference attacks easier.
