Countersign
A prototype I-HITL system that uses consumer mobile devices as a trusted approval step, pluggably enhancing the security of existing HITL systems to prevent AI agents from bypassing human oversight.
Timeline (last 90 days)
The paper proposes a prototype I-HITL system called Countersign, which can use off-the-shelf consumer mobile devices to plug into and augment existing HITL systems, enabling pluggable deployment without completely restructuring the security architecture.
Countersign moves the approval action to a trusted device that the agent cannot compromise; as an independent trusted computing device with a secure element and biometric capabilities, a phone is suitable for taking on the approval role.
