Enhancing Healthcare Data Privacy with Zero Knowledge Proof on AWS

Abstract

Zero Knowledge Proof (ZKP) is a cryptographic method that allows a prover to demonstrate to a verifier that a statement is true without revealing any additional information. This is highly relevant in healthcare, where data privacy is critical. By integrating ZKP into healthcare applications, sensitive patient data can be securely verified without exposing unnecessary information. In healthcare, protecting sensitive data while enabling seamless collaboration between doctors, laboratories, and other entities is crucial. Sharing or verifying data often leads to privacy risks. The project aims to develop a ZKP protocol for a healthcare system, allowing secure and private verification of sensitive medical data between doctors and laboratories. The ZKP protocol is implemented using a hybrid system with cloud services and local machines for secure computation. AWS Key Management Service (KMS) handles encryption and decryption. The protocol creates cryptographic proof for verifiers to confirm data validity without accessing the data itself. Established cryptographic libraries and healthcare test data are used in the implementation. The system ensures scalability and security by leveraging AWS infrastructure and MySQL database integration for proof storage. The ZKP protocol successfully verified health care data without exposing sensitive information, reducing the risk of data breaches. This approach improves data security without compromising functionality, setting new privacy standards in healthcare data management.
