Traceable Registered Functional Encryption for Unbounded Inner Product in Web Service Platforms

This research proposes a new system called TRFE-UIP (traceable registered functional encryption for unbounded inner product) that helps web platforms securely compute operations on encrypted high-dimensional data while identifying who leaked information if it escapes. The system uses functional encryption (a method that allows specific calculations on encrypted data without revealing the original information) and eliminates the need for fixed data size limits, making it more practical for real-world applications with many users and large datasets.
