Vitalik Buterin Advocates Personalized Security Questions Over Signatures to Defend Against Deepfake Threats in Web3
-
Ethereum's Vitalik Buterin discussed Web3 security in light of increasing deepfake threats where audio and video can be faked.
-
Cryptographic methods like signatures are not enough - personalized "security questions" probing micro details people remember are more effective.
-
Security questions should be combined with other techniques like pre-agreed code words, multi-channel confirmation, protections against attacks.
-
Individual-to-individual security questions differ from enterprise-level ones and should be tailored.
-
No one technique is perfect, but layering adapted techniques can provide Web3 security even when audio/video can be faked.
