Vitalik Buterin, known for his contributions to the development of blockchain technologies, has proposed an innovative method to combat deepfakes, which are becoming an increasingly serious problem in the era of digital technologies. Deepfakes are audio and video forgeries created using artificial intelligence that can reproduce the voice and image of a specific person with a high degree of authenticity. This creates risks during video calls and transactions, where it is difficult to distinguish the real person from the forgery.

Buterin suggests using personalized security questions as an authentication mechanism, which could serve as an alternative to traditional security verification methods whose effectiveness is diminishing. These questions should be carefully selected based on personal experience and knowledge, making them difficult for unauthorized individuals to answer. This approach relies on human memory and personal relationships, which are weak points for artificial intelligence.

Buterin also emphasizes the possibility of complicating the questions by adding specific details, such as code words, coercion signals, multi-channel confirmation of important transactions, and intentional delays in performing crucial actions. This could significantly enhance the level of protection against theft of personal data and fraud.

In conclusion, Buterin urges blockchain project developers to exercise caution when implementing artificial intelligence systems, citing risks associated with potential errors and even concerns that AI could turn against humanity.
