Data Storage and Privacy Protection Mechanism

Bicern ensures user data privacy protection through innovative technical solutions, while giving users full control over their data. Below are the core technical details:

1. On-Chain Data Storage

Bicern uses blockchain technology to store key data, such as usernames, public profiles, and transaction history. The immutability and decentralization of blockchain guarantee the authenticity and integrity of data, and users can choose to display or hide their data, enabling privacy control.

Technical Details:

• Immutability: Once data is stored on the blockchain, it cannot be altered or deleted.

• Decentralized Storage: Data is distributed across multiple nodes, preventing single points of failure.

• Transparency: Data storage and transactions are verifiable, but only authorized users can view the content.

2. Off-Chain Data Storage

Bicern uses IPFS (InterPlanetary File System) for decentralized storage, suitable for large-scale multimedia content such as images, videos, and documents. IPFS offers distributed storage and efficient access mechanisms to ensure data security and integrity.

Technical Details:

• Distributed Storage: Data is stored across multiple nodes, preventing single points of failure.

• Efficient Access: Content addressing improves access efficiency.

• Privacy Protection: Uploaded content is encrypted to ensure only authorized users can decrypt and access it.

3. Zero-Knowledge Proofs (ZKP)

Bicern introduces Zero-Knowledge Proof (ZKP) technology, allowing users to prove the legitimacy of an operation without revealing any sensitive information (such as account balances, transaction amounts, etc.), significantly enhancing privacy protection.

Technical Details:

• Transaction Validation: Users can prove they have sufficient funds for a transaction without disclosing specific amounts.

• Privacy Enhancement: Private information remains secure during on-chain interactions.

• Reduced Data Leakage: Verifies transactions or identities without exposing specific data.

4. End-to-End Encryption (E2EE)

All communications between users are encrypted end-to-end (E2EE), ensuring that messages are not tampered with or intercepted during transmission from sender to receiver.

Technical Details:

• Key Pairs: Each pair of communicators has a public and private key; only the receiver can decrypt the message.

• Secure Transmission: Information is transmitted through encrypted channels to prevent eavesdropping.

• Privacy Guarantee: Even platform operators cannot decrypt user messages.

5. Data Sovereignty

Bicern empowers users with full control over their data. The platform provides data authorization and management tools, allowing users to decide whether to share data and view or modify access permissions at any time.

Technical Details:

• User Control: Users can modify data access permissions at any time.

• Transparent Records: Every instance of data sharing or modification is recorded on the blockchain to ensure transparency.
