Safe-Doc lexicon
Key definitions around pseudonymisation, Shadow AI and zero storage architecture.
- Pseudonymisation
- Replacing identifying data with neutral tokens (e.g. [PERSON_1], [ORG_2]), with optional restoration via a separate mapping. Defined by GDPR art. 4(5) as a security measure.
- Mapping
- Correspondence table between pseudonymised tokens and original values. At Safe-Doc: JSON export, encrypted, TTL-controlled, under your sole control : never a central archive at our end.
- TTL (Time To Live)
- Lifetime of a reversible mapping. After expiry, restoration is no longer possible : reducing the risk surface of retained data.
- Shadow AI
- Use of AI tools (ChatGPT, Claude, Gemini, Copilot…) outside the official company framework : no DPIA, no document control, no traceability. See AI Risks.
- Data-centric
- Security approach focused on the data itself: neutralise sensitive information at source, before it reaches a third-party AI model, rather than trying to control every tool or prompt.
