Data access

Control of which data a user or entity within the AI system has access to

The Explain card

Plain English
Data access is the control of which data each user, service or component inside an AI system is allowed to reach.
Example
A retrieval chatbot is given read access to the whole document store. A user from sales asks about salaries and the model happily summarises HR files it should never have seen.
Why it matters
Models inherit the permissions they are given, then share what they find with whoever is asking. Access control must be enforced at the data layer, not left to the model's judgement.
Hook
The model can only leak what it was allowed to read.
