Vitalik Buterin Proposes Method to Combat Deepfakes

Vitalik Buterin has proposed a groundbreaking approach to address the proliferation of deepfakes, powered by artificial intelligence (AI), which poses a significant threat to digital communications. Deepfakes manipulate audio and video, fabricating the voice and image of individuals, presenting a substantial risk during identity verification processes such as video calls or transactions. Buterin's innovative solution aims to counter this threat.

Buterin advocates for personalized secret questions as a robust authentication mechanism, recognizing the limitations of traditional security methods. According to him, cryptographic signatures have constraints, especially in scenarios where keys might be compromised or transactions coerced. Hence, Buterin proposes personalized questions tailored to individuals' experiences and knowledge, making it challenging for outsiders to provide correct answers.

The advantage of Buterin's method lies in its reliance on human memory and personal relationships, areas where AI falls short. By utilizing personal details known only to a select few and unattainable from the internet, these authentication questions can ensure reliable protection against data theft and fraud, assures Buterin.

Additionally, increasing question complexity by incorporating predefined code words, coercion signals, multi-channel confirmation for critical transactions, and intentional delays during crucial actions can further fortify security measures.

Buterin recently cautioned developers against indiscriminate integration of AI systems into blockchain-based projects, citing increased risks of various errors. In December, the Ethereum co-founder expressed concerns that artificial intelligence could revolt against humanity.
