What’s inside
- Patterns: loop, whorl and arch
- Minutiae with angles (ridge endings and bifurcations)
- Deterministic: store only the seed, not images
- Seeds via HMAC with a secret from your server config
- An npm package you bundle yourself, not a drop-in resource
Our take
A clever building block for MDTs and forensic RP. Your database stays lean because you never store images.
