In healthcare, trust is everything. Patients and providers share the most sensitive personal information with the expectation that it will be protected with the utmost care and integrity. As we bring the power of AI to claims adjudication, this responsibility becomes even more critical. An AI system is only as trustworthy as the security of the data it’s built on.
At ClaimSage AI, we understand that world-class AI requires world-class security. That is why we have engineered our platform from the ground up with a security-first mindset, creating a fortified environment designed to protect our partners’ and their members’ data at every step. Our commitment is simple: to handle sensitive health information with the same rigor and security as a bank handles its assets.
Our Architecture: The Data Privacy Vault
The cornerstone of our security strategy is a cutting-edge architecture we call the Data Privacy Vault. This model is designed to fundamentally minimize the exposure of Protected Health Information (PHI), ensuring our core AI systems never need to access raw, identifiable patient data.
Here’s how it works:
1. Secure Ingestion
When data enters our system, sensitive PHI (like names, addresses, and Member IDs) is immediately segregated and placed into the secure, isolated “vault.”
2. Tokenization
The vault replaces this sensitive information with non-identifiable, irreversible tokens.
Example Transformation:
Original: John Smith, DOB: 01/15/1980, Member ID: 123456789
Tokenized: TX7B9K2M, REF: A3F9, ID: H8X2Q5P7
3. De-Identified Processing
Our AI models are then trained and operate exclusively on this tokenized, de-identified data. The AI learns patterns and makes predictions without ever “seeing” the underlying personal information.
4. Strictly Controlled Re-identification
Only at the final stage of the process, when a report is being prepared for the payer, is the information de-tokenized under strict, auditable access controls.
Defense in Depth: Multiple Layers of Protection
This architecture, combined with a defense-in-depth security posture, provides multiple layers of protection:
End-to-End Encryption
All data is encrypted with the strongest standards (AES-256) both when it’s at rest in our systems and when it’s in transit.
Our Encryption Stack:
- Data at Rest: AES-256-GCM encryption
- Data in Transit: TLS 1.3 with perfect forward secrecy
- Key Management: Hardware Security Modules (HSMs)
- Backup Encryption: Separate encryption keys with rotation
Logically Isolated Networks
We leverage secure cloud infrastructure, like AWS Virtual Private Clouds (VPCs), to create logically isolated networks that prevent unauthorized access.
Network Security Features:
- ✓ Private subnets with no direct internet access
- ✓ Network segmentation between components
- ✓ Web Application Firewall (WAF) protection
- ✓ DDoS protection and rate limiting
The Principle of Least Privilege
Our access control policies are strict. Team members and systems are only granted the absolute minimum level of access required to perform their specific function.
Access Control Matrix:
| Role | PHI Access | AI Model Access | Audit Log Access |
|---|---|---|---|
| Data Scientist | None | Read-Only (De-identified) | None |
| Security Admin | None | None | Full |
| Clinical Reviewer | Controlled | Read-Only | Limited |
| System Admin | Emergency Only | Configuration | Read-Only |
Continuous Monitoring & Auditing
Our security is not static. We continuously monitor our systems for threats and maintain immutable audit logs of all data access.
Real-Time Monitoring:
- Anomaly detection for unusual access patterns
- Automated threat response systems
- 24/7 Security Operations Center (SOC)
- Quarterly third-party security audits
Compliance and Certifications
Our commitment to security is validated by rigorous third-party assessments:
- HIPAA Compliant: Full compliance with all HIPAA security and privacy rules
- SOC 2 Type II: Annual audits of our security controls
- HITRUST Certified: Meeting the healthcare industry’s highest security standards
- ISO 27001: International standard for information security management
Transparency in Security
Just as we believe in AI transparency, we believe in security transparency. Our partners receive:
- Monthly Security Reports: Detailed metrics on security performance
- Incident Notifications: Immediate notification of any security events
- Annual Security Reviews: Comprehensive security posture assessments
- Access to Security Documentation: Full visibility into our security practices
The Human Element
Technology alone doesn’t ensure security. Our team undergoes:
- Comprehensive background checks
- Annual security training and certification
- Regular phishing simulations
- Strict confidentiality agreements
Your Data, Your Control
We believe that you should always maintain control over your data:
- Data Portability: Export your data at any time
- Right to Deletion: Complete data removal upon request
- Granular Permissions: Control exactly what data we can access
- Audit Access: Full visibility into how your data is used
By building our platform on this foundation of security and privacy, we offer our partners more than just an AI tool. We offer them peace of mind, assuring them that in partnering with ClaimSage AI, their data—and their trust—is secure.
