We distinguish legal boundary decisions using automated document checks; we address meaningful human oversight, automation bias, override, fallback, and appeal mechanisms through a practical model.
We are designing a security architecture that uses least privilege, signed tool outputs, schema-based messages, and a kill switch to defend against prompt injection, deepfake, fake service responses, replay, and agent chain attacks.
No. Short-lived templates, local matching and purpose-bound tokens can reduce centralized biometric traces.
It can automate low-risk checks, but uncertain or legally consequential decisions require explainability, appeal and human authority.
By assigning document, biometric, visa, and travel checks to task-based AI agents, we are examining what processes can be automated from a technical standpoint, the benefits of doing so, and why the final decision must remain with a human.
We address presentation attacks, deepfake injection, morphing, token replay, and service disruptions using a layered decision model, and explain the design of a secure manual fallback with code examples.
We are designing privacy-protected airport biometrics featuring a "Journey" pseudonym, 1:1 verification, selective data sharing, biometric template protection, and automatic deletion policies.
By treating the face not as a travel document but as a biometric link, we are exploring how a short-term transit authorization can be generated using ePassport/DTC, liveness detection, flight segments, and transit rules.
