Features

The next era of security built to outlast passwords and quantum computers.

The core functionalities that make Veintree the most secure identity platform, built for the post-password, post-quantum world.

Core Security

Trusted Execution Environment

Your unique identity data is processed inside a hardware-isolated secure enclave, completely shielded from software, operating systems, and third parties. Only you control access.

Privacy

Personal Data Repository

Your data, your rules. A self-sovereign vault where you control encryption, access, and sharing, powered by zero-knowledge proofs for absolute privacy.

Healthcare

Medical Files Repository

Portable, encrypted health records, accessible only with your unique personal verification. Share securely with doctors and revoke access instantly.

Verification

Proof of Signature

Forget passwords and PINs. Sign with your veins. Cryptographically secure, legally binding, and impossible to forge.

Access Control

Proof of Presence

Forget passwords. Ditch surveillance. Your veins are your key. Unlock access with the proof only you can provide.

Authentication

Proof of Password and Seed Phrase

Eliminate passwords and Seed Phrase entirely. Your vein pattern generates a unique cryptographic key for every service. No memorization, no phishing, no reuse attacks. Authentication as natural as waving your hand.

How It Works

Four steps to
sovereign identity.

Step 01

Scan

The sensor captures over 1 million unique data points from your vascular pattern in under 5 milliseconds.

Tap to flipHover to flip

Step 01

Scan

Vein patterns are inherently unique, internal, and impossible to forge, unlike fingerprints, iris or facial recognition.

The capture process are fully decentralized:

The encrypted 'Locks' data from your hands at enrollment are encrypted and stored, and remain unreadable and non-transmissible.

The 'Key' data of each scan is never recorded; it is mathematically converted into a secure cryptographic template, and used to make a local comparison between your "Locks" and your "Keys".

Tap to flipHover to flip

Step 02

Encrypt

Your vein structure is cryptographically secured on-device, turning your physical identity into a zero-knowledge proof. No raw data, no exposure.

Tap to flipHover to flip

Step 02

Encrypt

Your vein template is encrypted directly on your authEnTHICator using a private key generated in a secure enclave (TEE). No raw data ever leaves your device.

Zero plaintext storage – Not even Veintree can access your original biocryptographic data.

Quantum-resistant security – Protected by CRYSTALS-Kyber (encryption) and CRYSTALS-Dilithium (signatures).

Tap to flipHover to flip

Step 03

Verify

No one but you controls your identity. A decentralized network validates your encrypted proof, ensuring security and privacy by design.

Tap to flipHover to flip

Step 03

Verify

Lock-Key Authentication: Privacy-Preserving & Decentralized.

You prove ownership of your encrypted vein template without exposing it, using Zero-Knowledge Proofs (ZKP). The Trusted Execution Environment (TEE) validates the match between the "Lock" (stored vein pattern) and the "Key" (live scan) on-device, with no central authority involved.

No raw biometrics stored – Only cryptographic proofs.

No single point of failure – Fully decentralized.

Unphishable & quantum-resistant – Built for the future.

Tap to flipHover to flip

Step 04

Own

The institution (bank, server, or authority) issues a Verifiable Credential (VC), which is stored directly in your self-sovereign identity (SSI) wallet. No middlemen. No masters. Just ownership.

Tap to flipHover to flip

Step 04

Own

The Future of Identity: Self-Sovereign & Unbreakable.

You Own Your Identity – Stored in your digital wallet, not a corporate database. Revoke access anytime.

Works Everywhere – Banks, governments, apps, all via DIDs & Verifiable Credentials (VCs) and the Veintree application.

Consent You Can Trust – Every use requires your cryptographic signature (smart contracts or ZKP-secured OAuth).

Built to Last – No single point of failure. Your identity stays secure even if you lose your Auth(EnTHIC)ator.

Anti-spoofing

Proof of Liveness

Liveness detection is ensured through real-time blood flow monitoring. Infrared sensors track carboxylated hemoglobin movement, making it impossible to fool the system with photos, videos, or artificial replicas.

Anti-spoofing

Proof of Liveness

The Core Principle: "Alive = Moving Blood"

Veintree doesn't just check what the veins pattern look like. It verifies that blood is actively flowing through them. This is the liveness check.

If blood flow matches the expected pattern (e.g., correct pulse, no anomalies), authentication succeeds.

Unique human

Proof of Personhood

Anti-Sybil verification ensures you're a unique human, without collecting personal data. No name, no email, no ID. Just cryptographic proof that you exist, you're real, and you're not a bot.

Anti Sybil resistance
Zero personal data collection
Bot elimination
One person = one identity

Unique human

Proof of Personhood

Veintree's Proof of Personhood is a secure, privacy-first way to verify you're a real, unique human, without exposing your identity, biographical details, or personal data. It's the digital equivalent of casting a vote by dropping an anonymous ballot without handing over your passport, driver's license, or even your name.

Sybil attacks (where one entity creates fake identities to manipulate systems) are a major problem in decentralized networks, DAOs, and online communities. Veintree solves this with three core assurances:

Liveness detection (real-time blood flow monitoring) confirms you're a living human, not an AI deepfake.

1- You Exist
2- You're Unique
3- You're Not a Bot (or a Duplicate)

Decentralized ID

Proof of Identity

Full decentralized identity verification anchored on-chain. Combines biometric proof with verifiable credentials to create a portable, censorship-resistant identity that works across chains, borders, and institutions.

Cross-chain portable
Verifiable credentials
Censorship resistant
Institutional interop

Decentralized ID

Proof of Identity

Identity is a Human Right.

For centuries, identity has been a tool of control, issued by kings, governments, and corporations to track, tax, and restrict people.

Veintree returns identity to its rightful owner: you.

Your identity. Your rules. No gatekeepers.

You control your identity
You vote in DAOs without doxxing
You access healthcare without paperwork
You prove your age without showing your ID

Questions & Answers

"Fingerprint and Face ID are like using your house key as your password."Using your biometric as an access key is making them public. Anyone can copy it. If stolen, you can't change your locks.Fingerprints can be lifted. Faces, Iris and voices can be copied and faked.Why trust a system that stores your face or your fingerprint when you can own your veins?Veins? Only you have yours.Veintree Solution: It's like having a magic key that changes shape every time you use it, and only you can make it work.

We've designed Veintree to keep you in control, even in the worst-case scenarios.Minor cuts or burns? The scanner adapts to read your veins through them.Severe injury? You can temporarily use recovery codes or other body parts until you're ready to re-enroll.It's Not Just About Your HandsYour vein pattern is one part of your identity. Veintree uses a backup system (like a digital "safety net") to ensure you're never locked out.Veintree doesn't just give you a key. It gives you a whole recovery plan.

No, your vein pattern (or any raw biometric data) is never stored on a blockchain, or anywhere else. It's like a secret handshake.Here's how Veintree actually works:When you scan your hand, the Veintree dongle instantly turns your vein pattern into a secure digital "key", like a password that's impossible to guess or steal. This key never leaves your device. Not even Veintree can see it.Think of the blockchain (if the App uses one) like a public phonebook: it's just there to prevent tampering, like a notary stamp for your credentials, just a list of "Person A is a verified human".Your secret stays secret. The blockchain just helps the world trust that you're you."Your vein pattern is yours alone. Veintree just helps you prove it, without ever touching it."

Veintree's system is blockchain-agnostic, meaning it's designed to integrate with multiple decentralized networks for identity management.Veintree aligns with W3C DID (Decentralized Identifier) standards, which are compatible with most major blockchains (e.g., Ethereum, Polkadot, Solana, Hyperledger, Algorand).Veintree uses Verifiable Credentials (VCs) for tamper-proof identity claims, which can be anchored to any blockchain supporting smart contracts.Veintree's on-edge bio-cryptography (vein pattern + post-quantum encryption) is independent of the blockchain layer, allowing flexibility in choice of network.Veintree's identity system is blockchain-agnostic, focusing on DID/VC standards. The specific blockchain(s) used depend on the deployment (public, private, or hybrid) and client requirements, with no biometric data ever stored on-chain.

Show Long-Term CommitmentUse Veintree's tech in production, not just a hackathon project.Bring users: onboard 100+ users to your Veintree-powered app.Solve a hard problem (e.g., "I integrated Veintree with [legacy enterprise system]").

Yes! Veintree is uniquely positioned for physical access control (PAC), and it solves many of the pain points of traditional systems (keycards, fingerprints, facial recognition). Here's how it works and why it's a game-changer.How Veintree Enables Physical Access Control1. The Core Tech: Vein Pattern AuthenticationA user scans their palm or dorsal veins using a Veintree dongle or embedded sensor.The system matches the unique vein pattern (stored as an encrypted template) to grant access.No biometric data is stored on a central server. Only a cryptographic hash on the blockchain (or local device).2. Decentralized Identity LayerBlockchain-anchored credentials: access permissions are tied to a decentralized identifier (DID) on a blockchain (e.g., Ethereum, Solana, Hyperledger). Example: a Veintree DID could grant access to Building A, Floor 3, Room 101. Revocable instantly if the DID is compromised.Zero-knowledge proofs (ZKPs): prove you have access without revealing your vein pattern (e.g., "I'm authorized for this door", the system verifies without seeing your biometric).3. Hardware IntegrationVeintree dongles: plug-and-play USB/NFC dongles for existing door systems (e.g., replacing keycard readers). Example: a hospital could retrofit doors with Veintree dongles for staff access.Embedded sensors: vein scanners integrated into smart locks, turnstiles, or elevators. Example: a co-working space could use Veintree for touchless check-in at entry points.Mobile + dongle combo: users authenticate via phone + vein scan for multi-factor security (e.g., "Scan palm + approve on app").

GDPR Article 9 classifies biometric data as "special category data" (highest protection). Veintree complies via:A. No "Biometric Data" Under GDPR?GDPR Definition (Art. 4(14)): "Biometric data" = personal data resulting from specific technical processing relating to physical/physiological characteristics used to uniquely identify a person.Veintree's Loophole: raw vein patterns are never stored. Only cryptographic hashes (one-way transformations). No "technical processing" for identification. Hashes are matched locally (on-device) and never reconstructed into biometric data.Legal Precedent: similar to password hashes (not considered biometric data under GDPR).B. If Treated as Biometric DataExplicit Consent (Art. 9(2)(a)): users sign smart contracts (or OAuth 2.0 + ZKPs) to opt-in to vein authentication. Granular consent: users can revoke access at any time (e.g., "Delete my vein hash").Data Protection by Design (Art. 25): on-device processing: vein scans are converted to hashes locally (no cloud transmission). Decentralized storage: hashes stored on blockchain (public ledger) or the user's device, not Veintree's servers.And much more to come…
