Privacy

Protecting the people whose data flows through the system.

Definition

Handling personal data lawfully and carefully in AI systems: minimising what is sent, redacting identifiers, controlling retention, and honouring access and deletion requirements.

Practical measures that work: redact before sending, keep raw data in your own store and send only what the task needs, and make deletion reach the vector index and any memory layer.

Minimisation is the intervention with the best ratio of effort to risk removed: if a value never leaves your network, it cannot appear in a log, a transcript or someone else’s context. Where the full value is genuinely needed, keep the mapping on your side and pass a token.

How people use it
Before an assistant touches customer records.
"Strip identifiers before the model sees anything, and make sure deletion also removes the embeddings."
Worked example

The identifier that was not needed

Classifying support tickets where the customer name is irrelevant to the category.

Redact before the call and the name never leaves. The classification is unchanged, the retention question mostly evaporates, and no downstream system has to be trusted with a record you did not have to share.
