# Joint Privacy Protection

### 1) Key Technologies

***Symmetric Encryption:*** Used for local data storage to ensure data security when the device is offline.

***Asymmetric Encryption:*** Used for data upload and transmission processes to ensure confidentiality and security during communication.

***Zero-Knowledge Proofs (ZKP):*** Used for anonymizing sensitive information and protecting user privacy.

***End-to-End Encryption (E2EE):*** Ensures full-link data transmission protection.

***Distributed Storage (DePIN):*** Eliminates the risks of centralized storage, enhancing data availability and resistance to attacks.

### 2) Privacy Protection Advantages of Joint Ecosystem

***Full-Link Protection:*** From data collection to storage, transmission, and sharing, encryption and verification technologies are used throughout, ensuring the security of user data.

***User-Driven Privacy:*** Data upload, storage, and sharing all require user authorization, ensuring privacy sovereignty.

***Efficient Collaboration:*** By combining the technologies of iPulse Protocol and wearable devices, efficient collaboration in health management and scientific research is promoted, while privacy is guaranteed.
