Behavioral Authentication · since 2007

AI may steal your identity.
Take it back.

We identify people by how they type, move, and act. Not what they remember. Not the device in their hand. Not data we ever collect about them.

See the signal Six ways we're used
The Fourth Factor

Something you do.

Three factors verify an artifact. The fourth verifies the act.

A ledger

Since the 1980s, authentication has asked the same three questions. Each verifies something separable from the person. Each one can therefore be taken.

We built software that measures the performance of an action and matches it to the person producing it. The credential is the doing. It cannot be remembered, stolen, or handed off.

01
Know A password
Something the person remembers.
It can be copied, guessed, or phished.
02
Have A phone or key
Something the person carries.
It can be lost, stolen, or handed off.
03
Are A fingerprint
A static body feature.
It can be cloned from a surface or photograph.
04
Do A performance
How the person acts in the moment.
Being, in fact, that person.
— Positioning
Know who you are in touch with.
Use Cases

Six places the signal already works.

UC·01 / Security

Password-less login that can't be phished.

The credential is the performance. Replaying a stolen password fails because the person typing isn't the one who set it.

  • Windows Credential Provider deployed
  • No password store to breach
  • Continuous re-verification during session
UC·02 / Authorship

Prove who actually wrote the document.

Every essay, form, or report carries a signature in how it was written. AI cannot fake the performance that produced it.

  • Academic integrity verification
  • Fraud and ghostwriting detection
  • Runs silently during normal typing
UC·03 / Controls

Parental consent that can't be handed off.

A child cannot perform as the parent. A verified gatekeeper approves access, and the system detects substitution instantly.

  • COPPA-compliant consent workflow
  • No personal data collected on minors
  • Substitution detection during use
UC·04 / Provenance

Cryptographic signature for what was posted.

A post, comment, or data submission carries the performance of the person who produced it — verifiable after the fact.

  • Chain-of-custody for user-generated content
  • Synthetic-content rejection at the source
  • Audit trail without storing the author
UC·05 / Medical

Catch neurological drift before symptoms show.

Changes in typing rhythm correlate with cognitive decline and post-concussion recovery. The keyboard becomes a daily clinical instrument.

  • Longitudinal cognitive baseline tracking
  • Concussion return-to-play assessment
  • Passive, continuous measurement
UC·06 / TickStream®

Windows login without a password at all.

A Credential Provider that replaces the Windows login with a cadence-authenticated sign-in. Nothing to remember, nothing to phish.

  • Native Windows Credential Provider
  • Zero-training enrollment in under a minute
  • Silent continuous re-verification after sign-in
Method

Read the signal. Verify the performance.

Three measurements. One identity.

The system observes three physical signals during any normal interaction: how long a key is held, how long before the next key, and how the body steadies the device. Each signal is noisy alone. Together they form a signature.

  1. 01 Observe Dwell, flight, pressure, and motion captured while the person performs a normal action.
  2. 02 Compute A Euclidean performance score is calculated against the person's stored baseline, on-device.
  3. 03 Decide Below threshold: continue silently. Above threshold: interrupt, log, or step up. No data leaves.
