Research on Data Privacy Protection Scheme Based on Blockchain

This paper conducts an in - depth study of data privacy protection methods based on consortium blockchains. With the arrival of the era of massive data, data privacy protection has become of vital importance. By adopting AES and HECC encryption algorithms, the encryption and decryption efficiency of privacy data has been effectively improved, and the security of privacy data has been strongly ensured. Verified by experiments, in the specific application scenario of data privacy protection, this scheme demonstrates excellent privacy and high feasibility. Compared with existing solutions, this scheme has significant advantages in the backup management of massive data and can better meet the actual application requirements. This indicates that the scheme provides a practical and efficient solution for data privacy protection, and is expected to be widely applied and promoted in related fields.
