🔏User Data Privacy

With the development of the internet and big data technology, the collection and use of user data have become increasingly widespread. However, frequent data breaches and privacy violations have raised significant concerns about data privacy protection. To better safeguard user data privacy, we have introduced an advanced cryptographic technology—ZKStarks (Zero-Knowledge Scalable Transparent Argument of Knowledge)—and integrated it with the WABA public blockchain to build a comprehensive user data privacy protection solution.

What is ZKStarks?

ZKStarks is a zero-knowledge proof technology that allows the verification of certain data's authenticity or compliance without revealing the actual data. Compared to traditional zero-knowledge proof technologies, ZKStarks has the following advantages:

• Scalability: It can handle large datasets, making it suitable for various application scenarios.

• Transparency: It requires no trusted setup, enhancing the system's security and credibility.

• Efficiency: The computational cost of generating and verifying proofs is low, making it suitable for applications with high real-time requirements.

ZKStarks have mature and widespread technical applications in blockchain technology. Public chains provide strong privacy protection through their decentralized, tamper-proof, and transparent nature.

Primary Privacy Protocols Followed

Our solution strictly adheres to the privacy protocols and security requirements outlined in the article "Security and Privacy Requirements in the Public Utility Space," including but not limited to:

• Data Minimization Principle: Collect and process only the minimum amount of data necessary to complete specific tasks, avoiding unnecessary data collection.

• User Consent and Transparency: Ensure users are informed and consent to the collection and use of their data, providing clear privacy policies and data usage explanations.

• Data Anonymization and De-identification: Remove or hide information that can directly identify users during data collection and processing to protect user privacy.

• Secure Data Storage and Transmission: Use strong encryption technologies to protect data during storage and transmission, preventing data breaches and unauthorized access.

• Access Control and Auditing: Implement strict access control mechanisms to ensure only authorized personnel can access sensitive data, with regular security audits and monitoring.

• Data Destruction: Employ secure methods to thoroughly destroy data when it is no longer needed, preventing data recovery and breaches.

Our solutions strictly comply with relevant laws and regulations in the U.S., including the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), etc., to ensure the legitimacy and compliance of the user's data processing process. The WABA Public Chain technology follows these laws and regulations in terms of data privacy protection, respecting the user's privacy rights and safeguarding the security of user data.
