How it works
Architecture

Keypair

ECDSA P-256 key generated via WebCrypto and stored in IndexedDB. Never leaves the device.

Commitment

Pedersen commitment over collected signals. Binds the fingerprint without revealing it.

Verify

Re-collect signals and compare against the commitment. Detects drift without exposing raw values.
