Guardians of the State: An Air-Gapped AI Fortress for Consumer Data (Rachna Srivastava (DFPI))
talk · Story page
The fiber into California's financial-fraud system is cut in half, a laser transmitter outside and only a receiver inside, chosen over a software firewall because any configuration can be misconfigured. After a model-centric first build collapsed within two hours, Kafka and Spark now hand the models data already made sane.
In plain words
- California's financial regulator built a fraud-detection system where information can physically enter but cannot physically leave.
- Incoming information travels through a cut fiber cable, with a laser sender outside and only a receiver inside.
- Other software records, replays, and cleans the information before automated analysis begins.
- Consumers get stronger privacy, while regulators can reproduce and defend every decision years later.
