Problem addressed
MSMEs face trust and privacy challenges in data transactions. Buyers struggle to evaluate data comprehensively before purchase, while sellers fear unauthorized replication. Additionally, managing multiple keys for encrypted datasets increases operational complexity and security risks.
Innovation
- A data exchange framework based on polynomial commitment cryptography and and Trusted Execution Environment (TEE) that facilitates data transactions by enhancing trust between data buyers and sellers.
- A single Polynomial Commitment Multiple Access (PCMA) token that streamlines key management for accessing multiple encrypted datasets from multiple sources.
- Data evaluation within Trusted Execution Environment (TEE) to ensure privacy protection.
Key impact
- Addresses trust issues in data exchanges, facilitating market growth.
- Offers single-key management for multiple datasets, enhancing user experience and security.
- Supports comprehensive data evaluation before payment, safeguarding buyer interests.
- Enhances efficiency and privacy protection in data transaction platforms.
Application
- Facilitate effective management of data assets on data exchange platform
- Make access to data assets more secure and efficient on data exchange platform
- Achieve effective data quality assessment while protecting the security of data assets
