Research on Blockchain's Privacy-Enhanced Security System

Glossary

Term DefinitionsBlockchain is a decentralized distributed ledger technology used to record transaction data. Smart Contract is a piece of code stored on the blockchain that is automatically executed when pre-set conditions are met. Private Key is a key used to decrypt data and authorize transactions, which should be stored confidentially. Public Key is used in pairs with a private key to encrypt data and verify transaction signatures. OTP (One-Time Password) is a one-time password that expires after each use to enhance security. XOR (Exclusive OR) is a logical operation commonly used in encryption algorithms. Virtual Block is a method of storing encrypted data on the blockchain to enhance data privacy. Physical Block is the basic unit of the blockchain, containing information such as transaction data and hash values. Key Exchange Blockchain is a blockchain used to securely exchange keys. Transaction Request is an operation request submitted by a user to the blockchain network for processing, such as a transfer or a smart contract call. Test questions

Answer

The patent proposes a solution to the privacy leakage problem caused by high transaction transparency in the public chain network, especially when it involves sensitive information such as financial transactions and identity authentication.

The user device first selects a specific key generation algorithm and encryption algorithm, then generates a private key in combination with a one-time password, and generates the corresponding public key through the encryption algorithm.

The virtual block is used to store encrypted transaction information, and only users with the corresponding key can decrypt and access it, thereby protecting user privacy.

This scheme uses virtual blocks, asymmetric encryption, and one-time passwords to hide the user's real identity and transaction details, thereby protecting the privacy of the user's transaction information.

The key exchange blockchain is used to securely exchange user public keys to prevent middleman attacks and information leakage.

This scheme stores the user's private key and the one-time password after XOR operation. Even if the attacker obtains the stored key information, the real private key cannot be restored without the one-time password.

This scheme uses asymmetric encryption technology. Only users with the corresponding private key can decrypt and access the encrypted data stored in the virtual block, ensuring that only authorized users can access it.

Compared with traditional security measures, this scheme has higher security, better privacy protection capabilities, stronger traceability and lower costs.

This patented scheme can be applied to financial transactions, supply chain management, identity authentication, electronic voting and other fields.

The future development directions of this patented scheme include: improving system efficiency, enhancing system scalability, developing safer encryption algorithms, and integrating with other blockchain technologies.
