A Comprehensive Decentralized Digital Identity System: Blockchain, Artificial Intelligence, Fuzzy Extractors, and NFTs for Secure Identity Management

Existing digital identification systems are often vulnerable to attacks as they are commonly based on authentication methods such as passwords, PIN codes, biometric data, etc., which can be easily forged or compromised. In this letter, we propose a digital identification system based on a unique set of user biometric data processed by Artificial Intelligence (AI) and fuzzy extractors to generate a cryptographically secure password linked to a unique Non-Fungible Token (NFT). Our system provides decentralized identification based on blockchain technology, which eliminates problems associated with centralized identification systems, such as cyber-attacks on central servers and data leaks. Our proposed system offers a higher level of user identification security by linking the user to their data through a unique NFT, generating a cryptographically secure password, and processing large volumes of biometric data using AI and fuzzy extractors. Our system provides a solution to many of these problems, making it important and relevant to many industries, including banking, medical, and financial sectors. The use of decentralized storage of information on the blockchain provides a high level of protection against hacking and reduces the likelihood of data breaches, making our system particularly relevant in the field of financial services and personal data protection.
