Human-Centered Contact Tracing Apps

" summary

A human-centered contact tracing platform uses Neo4j to store meetings as nodes and edges and runs simple graph traversals to find direct and second‑degree exposures, enabling real‑time alerts. It records contacts via peer-to-peer scanning or by tapping national e‑ID into a pocket device, stores timestamps, and demonstrates performance on roughly 10,000 interactions. The claim is that graph database queries make multi‑hop tracing far simpler and faster than SQL joins and that notifications are delivered immediately.
