Data Security and Privacy

Details of mechanisms to ensure data security and privacy

The HCX protocol is designed with a strong emphasis on safeguarding sensitive information exchanged during the claims process—such as personal identifiers and health-related data. In addition to facilitating secure data exchange, the Data Security and privacy measures in HCX align with key regulatory frameworks including India’s Personal Data Protection Bill (2019), the Information Technology Act (2000), and—where applicable—international standards like the GDPR.

While the responsibility for securing data at rest lies with the sender and receiver, in accordance with applicable local regulations, HCX defines a robust approach for data protection in transit, API-level security, and message integrity. These mechanisms not only meet present-day privacy and security expectations but also offer the flexibility to adapt to evolving data protection laws—ensuring continued compliance without compromising the confidentiality or integrity of sensitive health information.

A wide range of language-specific libraries are available to implement the necessary encryption, digital signing, and verification mechanismsrecommended in this protocol.

The subsequent sections detail the layered security model used in HCX:

• Transport Layer Security (SSL/TLS): For securing communication channels.

• API Security: Including token-based authentication and access control.

• Payload Security and Message Integrity: Ensuring end-to-end confidentiality and tamper detection.
