Secure Identity

Decoupling medical validation constraints from standard cloud storage nodes to guarantee compliance.

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.

Local Cryptography

Compiles cryptographic proof matrices directly inside client device runtimes.

SQLCipher Storage

Protects off-line database logs with AES-256 memory encryptors.

ZKP Cryptography

Select a medical credential type, then trigger the proof generator to observe how zero-knowledge verification prevents PII disclosure.

Native Companion App

Medwlt operates natively on iOS and Android using Flutter. It is constructed around local identity storage concepts to ensure doctors can display validation attributes even when running off-line inside secure hospital basements.

01

Biometric Gateway

Integrates secure system biometrics directly with device key chains to prevent credential access upon loss.

02

Dynamic Verification QR Codes

Generates short-duration validation tokens rendered as rotating QR patterns to prevent duplication attempts.
