## TL;DR

Privacy-preserving record linkage (tokenisation) that lets real-world datasets be joined without exposing identities.

## Summary

Datavant, based in San Francisco, provides privacy-preserving record linkage, known as tokenisation, that lets real-world datasets be joined without exposing patient identities. Its de-identification and linkage infrastructure is used by most US real-world data vendors and registries, which makes it the plumbing beneath much of the sector. OnCo links it to oncology EHR and real-world data platforms. Whether tokenised linkage stays private as datasets multiply and re-identification techniques improve is the open question that regulators and patients will keep asking. The real-world data platform page carries the wider debate.
