What happened

On 2024-03-06 the AEPD issued a precautionary measure preventing Worldcoin from continuing to process personal data in Spain. The regulator's order followed complaints alleging the company did not provide sufficient information to users and raised privacy concerns about collecting and processing biometric iris scans. International and Spanish press covered the suspension and related court actions. Local reporting later stated authorities ordered deletion of data collected in Spain in December 2024.

  1. 01 · TriggerA prompt pushes against a deployment boundary.

The output crosses a policy boundary the deployment had defined.

The root failure was governance and legal compliance for processing sensitive biometric identifiers: regulators found insufficient transparency and an unclear lawful basis for collecting and processing iris scans. This represents a breakdown in data-protection controls, consent processes, and operational safeguards rather than a failure of an ML model. Those compliance gaps triggered precautionary regulatory measures and later deletion orders.

  • Prism
  • OmniGuard

This entry sits in the index's predictive wing: a system that scores, ranks, perceives, or steers rather than generates. Realm's runtime layer is built for the generative and agentic systems now moving into these same decision seats, where it watches a model's internal state and holds an unsupported claim or an unchecked action before it commits. The control gap on this record, an automated decision that reached people with no runtime check in front of it, is the same gap. The index keeps predictive failures on the record because the pattern carries straight into the systems shipping today.
