Vitalik Buterin proposed a way to combat deepfakes

Ethereum co-founder Vitalik Buterin has proposed an innovative solution to combat the increasing threat of deepfakes in digital communications. Deepfakes, which are convincing fake audio and video generated by artificial intelligence (AI), pose risks when verifying identities during video calls or transactions. To address this problem, Buterin suggests implementing personalized security questions for authentication.

Traditional security verification methods, such as cryptographic signatures, have limitations and can be compromised. By using personalized security questions based on individuals’ unique experiences and knowledge, it becomes difficult for outsiders to provide correct answers. This approach relies on human memory and personal relationships, which AI cannot replicate.

Furthermore, the level of difficulty of these security questions can be increased by incorporating pre-agreed code words, duress signals, multi-channel confirmation of important transactions, and intentional delays in important actions. By adding these specifics, the protection against identity theft and fraud is strengthened.

Buterin has also emphasized the need for caution when introducing AI systems into blockchain-based projects, as they can increase the risks of errors. He has expressed concerns about the potential rebellion of artificial intelligence against humanity. Therefore, implementing security measures like personalized security questions can help mitigate these risks and ensure the safety of user funds.
