Key Components of the Tracking System
1. Currency Transaction Module
- Function: Facilitates secure transactions between parties using cryptographic keys.
- Process:
- The payer initiates a transaction request.
- The recipient generates a shared private key using the payer’s public key and their own private key.
- Transactions are verified and recorded on a blockchain for immutability.
2. Transaction Storage Module
- Local & Cloud Storage:
- Records are stored locally when offline and synced to a cloud database upon reconnection.
- Each entry includes the source coin’s owner, amount, and unique identifier.
3. Transaction Record Module
- Data Compression: Uses dynamic Huffman coding to compress transaction histories.
- Tracking Labels: Adds a cryptographically signed tag issued by the currency’s authority, containing:
- A random string.
- A verification code for audits.
4. Currency Tracking Module
- Permission-Based Access:
- Validates tracker identities via public/private key pairs.
- Grants access if the request’s verification code matches the label.
- Fraud Detection: Flags or halts transactions with invalid tags, notifying regulators.
How the Tracking Method Works
- Transaction Initiation:
- Shared keys enable secure communication between parties.
- Record Synchronization:
- Offline transactions are cached and later uploaded to the cloud.
- Data Embedding:
- Compressed transaction logs are appended to the recipient’s coins.
- Audit Trail Generation:
- Authorized entities reconstruct transaction chains using tracking labels.

| Regulatory Compliance | Enables transparent audits for legal and financial oversight. |
| Fraud Mitigation | Identifies and isolates suspicious transactions in real time. |
Frequently Asked Questions (FAQs)
1. How does the system ensure transaction privacy?
- Transactions are encrypted using ECDH key agreement, allowing only involved parties to decrypt data.
2. What happens if a tracking label is tampered with?
- The system either blocks the transaction or marks it as anomalous for further investigation.
3. Can this method track any cryptocurrency?
- It’s designed for authorized digital currencies with issuer-backed tracking labels, not fully anonymous coins like Monero.
4. How are offline transactions handled?
- Records are stored locally and synced to the cloud once online, maintaining continuity.
5. What’s the role of dynamic Huffman coding?
- It reduces the size of transaction histories, optimizing storage and transmission.
6. Who can access the transaction链条 (chain)?
- Only entities with verified permissions (e.g., regulators) can trace the full history.
Conclusion
This digital currency tracking system bridges the gap between decentralization and accountability, offering a robust framework for secure, auditable transactions. By integrating cryptographic protocols and adaptive storage solutions, it sets a new standard for transparency in the crypto economy.
