A Secure, Intelligent, and Compliant System for Organ Allocation and Transport Logistics
Developed to bridge lives through precision, security, and innovation.
LifeBridge is an enterprise-grade, end-to-end platform for real-time organ tracking, allocation, and transport coordination between donor hospitals, transplant centers, and logistics teams.
The system leverages strong encryption, real-time telemetry, and compliance-grade auditing to ensure that every organ reaches the right patient — safely, quickly, and transparently.
- End-to-end visibility from donor to recipient
- Automated organ matching using HLA and compatibility scoring
- Live tracking of transport status and environmental conditions
- Intelligent viability alerts and allocation prioritization
- AES-256-GCM encryption for all Protected Health Information (PHI)
- Role-based access control for hospitals, surgeons, and coordinators
- Full compliance with HIPAA, GDPR, and ISO/IEC 27001 standards
- Immutable audit trails and session-level event logging
- GPS-tracked organ transport with real-time synchronization
- Environmental data capture (temperature, weather, route deviation)
- Support for ground, drone, and airlift transportation modes
- Automated notifications and exception handling
- Field-level encryption with authenticated data access
- Multi-layer audit logging for every system event
- Chain-of-custody verification through digital signatures
- PHI access flags for compliance auditing
