A

At-source agent

Quarry's de-identification pipeline packaged to run on the owner's infrastructure, as a container or an on-prem agent.

At-source de-identification

The link from every delivered record to the signed supplier agreement and the buyer licence that cover it.

Code-mixed speech

Speech that switches between languages within a conversation or a sentence, such as Hinglish.

Contamination check

Pseudonymous ID

A stable stand-in for a patient, study or owner that keeps related records linked without identifying anyone.

Residual risk

The risk that remains, after de-identification, that someone could be re-identified. Assessed per dataset.
