Abstract

The healthcare industry faces challenges in protecting sensitive data amidst rising cyber threats. Fully Homomorphic Encryption (FHE) offers a transformative solution by enabling computations on encrypted data without decryption. This ensures privacy throughout data handling. This study explores the practical implementation of FHE in healthcare, leveraging the Microsoft SEAL library to create a secure framework for encrypted data analytics and sharing. The framework integrates BFV and CKKS encryption schemes for integer and real-number computations, respectively. It is tested using synthetic datasets simulating healthcare scenarios. Evaluations demonstrate high accuracy, robust noise management, and scalability for moderate dataset sizes. Results from encrypted computations align closely with plaintext benchmarks validating FHE's effectiveness in privacy preservation. While challenges such as computational overhead and noise depletion in complex operations remain, this research underscores the potential of FHE to secure healthcare data, meeting HIPAA standards and enabling safe, efficient data usage. Future work will focus on scalability and optimization strategies.
