Deepfake-Resistant Verification: Rebuilding Trust After Voice and Video
Security teams used to treat a phone call or video meeting as a high-friction trust channel. That assumption breaks under commodity voice cloning and synthetic video. Familiar tone, recognizable face, and “urgent” delivery carry weak evidentiary value. Verification has to shift from perception-based trust to control-based trust. The risk shows up fastest in two workflows: incident coordination and financial authorization. Synthetic impersonation compresses decision time, increases confidence in false requests, and exploits existing escalation habits. When a request arrives through chat, voice, or video, the channel becomes a delivery vehicle, not proof of identity. The only reliable control is a separate, pre-defined verification path that deepfakes fail to satisfy. Deepfake resilience is a process design problem first. Detection helps, yet process changes reduce reliance on fragile human cues. The objective is simple: every high-impact decision requires an authentication and approval ...
