Data Deposit Management System Based on Blockchain Technology

doi:10.3969/j.issn.1671-1122.2019.08.002

Abstract

Abstract:

Digital assets are the products of modern high technology, which need to be stored and tampered-proof, and to be easily shared and verified. Traditional data depositing systems mostly cooperate with third-party platforms, depend on centralized management and lack security and reliability. Using blockchain technology, this paper designs a complete data depositing management system based on blockchain technology to ensure data security encryption and user verification. The system uses alliance chain architecture to classify and store different data types. The system adopts ID-based threshold ring signature scheme without trusted center, which meets the security requirements of unforgeability and unconditional anonymity. The system provides the functions of registration, upload, download and query, and provides a friendly interactive interface for users and underlying data, which effectively guarantees the authenticity, validity and security of data in data depositing system.

Key words: blockchain, data deposit, threshold ring signature, information security
