Medwlt Case Study

Medical credential checks have traditionally required scanning and emailing PDF verification sheets. This approach exposes sensitive Personal Identifying Information (PII) like Social Security Numbers and DEA License numbers, presenting significant security risks and compliance headaches. GCAN designed Medwlt to solve this by storing validation details locally under client-side databases and generating mathematically verifiable proofs.

Using client-side Rust compilers running inside Flutter applications, the app generates localized zero-knowledge proofs (ZKPs). Verifiers confirm critical licenses without holding or viewing clinical credential logs, satisfying HIPAA privacy guidelines under a unified schema.

Healthcare credential verification has historically relied on fragmented manual processes, physical paperwork, and insecure PDF sharing. Clinicians frequently had to expose sensitive Personal Identifying Information (PII)—including DEA numbers, licensing IDs, and national provider registry data—over unencrypted channels, creating significant risks of identity theft and regulatory compliance issues.

Our client needed a secure, enterprise-grade mobile solution that could instantly verify clinician credentials at hospital access points without storing sensitive data on centralized servers or exposing raw licensing logs during checks.

We engineered a native clinical credential wallet utilizing Flutter for cross-platform efficiency and Rust for high-performance local cryptography. Instead of sending raw credentials to the cloud, the application secures them locally using hardware-backed device keys and SQLCipher database encryption.

Verification is achieved via dynamic, short-lived verification codes. Hospital administrators can instantly confirm a clinician's active status via a web-based verifier portal without gaining access to their private underlying data.

The deployed ecosystem successfully eliminated the bottlenecks of medical onboarding and access control while ensuring absolute compliance with security standards.

By streamlining the check process from a manual review down to a secure three-second scan, hospital systems achieved massive operational cost savings and improved resource scheduling across shifts.
