Firstly, blockchain technology grants individuals control over their identity information, achieving autonomous information control and protecting personal privacy. Secondly, blockchain's  decentralized nature ensures the security and tamper-proof nature of information, reducing the risk of identity information leaks and tampering. Additionally, blockchain technology employs cryptographic methods such as hashing functions, digital signatures, and zero-knowledge proofs to encrypt, record, and store digital identities, ensuring the security of identity information during transmission and storage. Meanwhile, consensus mechanisms in blockchain networks ensure"}]}],"pr":"f165ad7dacba428a0eb24baff4cde2f9229f354bfe09f27421044fb0642798fe"}
