PostgreSQL 上去識別化的套件

在「PostgreSQL Anonymizer 0.5: Generalization and k-anonymity」這邊看到的套件,看起來可以做到一些常見而且簡單的去識別化功能:

The extension supports 3 different anonymization strategies: Dynamic Masking, In-Place Anonymization and Anonymous Dumps. It also offers a large choice of Masking Functions: Substitution, Randomization, Faking, Partial Scrambling, Shuffling, Noise Addition and Generalization.

看起來可以把欄位轉成 range 這件事情半自動化處理掉 (還是需要 SQL 本身呼叫這些函數),之後遇到 PII 的時候也許會用到...
