No human? No access.
Dydema makes that enforceable.
Dydema is a wearable + software that keeps privileged access live only while a real human is present.
When you’re not there, access drops automatically, with an audit trail.
Modern security systems authenticate identity at the start of a session. Passwords, MFA, device checks, and behavioral signals establish who is allowed in, but not whether a human remains present once access is active.That assumption used to hold. Agents shattered it.Agents and delegated AI can operate inside valid sessions without supervision. Privileged access persists after the human steps away. Sensitive actions execute unattended. When something goes wrong, there is no reliable proof of who, or what, was actually present.What’s missing is a fundamental control: a way to require and verify human presence at the moment privileged actions occur, not just when access is granted.
Dydema is a human-presence enforcement layer for privileged access.Dydema uses real-time physiological signals to confirm that a live human is present at the moment sensitive actions occur, and gates access accordingly. These signals are continuously generated by the body and are extremely difficult for automated systems to spoof in real time.The system is designed to be passive and low-friction. There are no puzzles to solve, no personal identity data to submit, and no behavioral training required. Dydema answers one question with high confidence: is a real human present right now?Our initial prototype is a lightweight wearable that measures signals like electrodermal activity (EDA), heart-rate variability (HRV), and EEG. These signals are evaluated in concert using real-time machine learning to confirm live wear and human presence.Dydema integrates as a control layer: enforcing presence during privileged sessions, high-risk commands, or sensitive workflows, without changing how users authenticate or work.
Dydema is designed to enforce human presence, not to surveil, profile, or analyze people.Dydema answers a single question: is a live human present right now? It doesn't measure attention, emotion, cognition, or intent.Dydema is built as a control, not a surveillance platform. It does not create behavioral profiles, track users across contexts, or expose raw physiological data to customers or third parties.
Our initial deployments focus on tightly scoped, high-risk environments, like security teams, financial systems, and regulated enterprise workflows, where it's critical to know that a real, supervised human is present. These early environments will let us validate enforcement, reliability, and auditability under real conditions.From there, Dydema expands outward as an API and control layer that developers and enterprises can integrate into their own systems, without changing their existing identity or access infrastructure.Our roadmap:
- Build and validate the hardware MVP
- Launch a private, presence-gated pilot environment
- Expand the presence API for partner and enterprise integrationIf you’d like to follow progress or explore early access, join our updates list. We’ll share milestones as we move toward production deployment.
