Dwaar
द्वारthe door · the gate — Rhythm-Based Access Control
What if your password couldn't be stolen, phished or shared — because it wasn't something you know, but the way you move?
Stolen and shared credentials are how secure systems fall; and shipping a fingerprint or a face to a cloud only moves the risk somewhere you don't control.
The situation
An operator signing in to Arsenal Command at a forward post
An operator reaches a console with no network. They type the same short phrase everyone on the team knows — but Dwaar isn't reading the words, it's reading the rhythm: how long each key is held, the gaps between them. That rhythm matches the one enrolled on this device, and they're in. A stolen password wouldn't carry it; a colleague typing the very same phrase types it differently. Nothing ever left the room.
How it plays out
Step by step
- 01
Type the phrase
The operator types a public cadence phrase — the words are not the secret, the timing is.
- 02
Dwaar reads the rhythm
It captures the dwell on each key and the flight between them — the personal signature in how you type.
- 03
Matched on the device
An RSN verifier compares the rhythm to the operator's enrolled template, right on the device — no cloud, no biometric sent anywhere.
- 04
Passphrase backs it up — and it learns
If the rhythm doesn't match, a passphrase confirms identity; the confirmed rhythm is learned, so Dwaar keeps up as your typing drifts.
The system itself
Under the bonnet
Dwaar is the access layer of Arsenal Command — the door to every other capability. An operator types a public phrase; the secret is the personal rhythm, the dwell on each key and the flight between them. An RSN verifier matches that rhythm to the operator's enrolled template on the device itself. A passphrase backs it up, and every rhythm it confirms is learned, so it keeps up as an operator's typing naturally drifts.
What it means for you
The bottom line
- ▸A key that can't be stolen, phished or shared
- ▸The biometric never leaves the device — no cloud
- ▸Training-free RSN match — deterministic & auditable
- ▸A passphrase fallback that learns your drift
