TIDAS Data Security Mechanism

Background and Challenges​

Carbon footprint data faces multiple authenticity challenges during application:

  • Data can be easily tampered with, leading to information distortion
  • Difficulty in tracing change history
  • High cost of traditional verification methods
  • Lack of common trust foundation in multi-party collaboration

These challenges not only affect data value but may also lead to compliance risks and trust crises.

Blockchain-Based Data Tamper-Proof Mechanism​

Blockchain, with its core features, provides an ideal solution for data tamper-proofing:

  • Immutability: Chain structure combined with cryptography ensures data is difficult to alter once recorded
  • Distributed Architecture: Eliminates single-point tampering risks
  • Timestamp Mechanism: Provides indisputable chronological proof
  • Consensus Mechanism: Ensures consistent recognition of data status among network participants

TIDAS Working Mechanism​

TIDAS builds an efficient data trust mechanism based on the Tiangong data platform and blockchain technology:

Process Design​

  1. Data Submission and Review

    • Contributors submit original data to the Tiangong platform
    • Platform review ensures data complies with TIDAS standards

  2. Hash On-Chain

    • Calculate hash values of processed data
    • Write hashes to blockchain and obtain transaction credentials
    • Associate stored data content with transaction hashes

  3. Verification Mechanism

    • Users obtain data and transaction hashes
    • Recalculate hash values of obtained data
    • Compare with blockchain records to verify integrity

Technical Features​

  • Lightweight Design: Only hashes on-chain, balancing performance and cost
  • Dual Protection: Combines platform management with blockchain tamper-proofing
  • Privacy Protection: Original data not directly exposed
  • Open Verification: Supports independent third-party verification

Practical Application​

We have collaborated with Ant Chain to develop a blockchain-based trusted solution for carbon footprint data, providing strong guarantees for the authenticity of carbon footprint data.
