A bank uses a video-based know your customer (KYC) verification process.

Liveness detection is the most effective countermeasure against deepfakes in video-based verification. AI-based liveness detection analyzes facial movement, micro-expressions, and other biometric cues to differentiate real humans from manipulated video content.

“To protect against identity spoofing and deepfake exploitation, biometric systems must incorporate liveness detection protocols capable of detecting synthetic imagery or falsified video data.”

Encryption (C) protects data at rest and in transit but does not prevent impersonation. Discontinuation (D) may not be necessary if effective countermeasures like B are in place.
