A deep-tech company building the trust layer of the digital state.
Sieve Technologies Inc. is a US-incorporated deep-tech company headquartered in Frisco, Texas. We design and operate Sieve ID, a sovereign, non-custodial identity and trust infrastructure that proves a living, present human is behind every digital act — without ever holding a recoverable copy of biometric templates, credentials, or personally identifiable data.
Our platform is delivered as Trust-as-a-Service (TaaS) in a white-label model, deployed under the brand of public agencies, state enterprises and regulated operators. We do not act as an intermediary or wrapper around third-party technology: the biovital engine, intelligence core, sharded storage protocol and identity provider are 100% proprietary and operated by Sieve.
Mission
Eliminate identity fraud, data custody risk and friction from the digital relationship between citizens, governments and the private sector — by replacing passwords, documents and central databases with a portable, sovereign identity bound to a living human.
Positioning
- Sovereign by contract. Deployed inside the partner's jurisdiction, under the partner's brand and legal regime.
- Non-custodial by design. Data stays with its holder. Sieve returns approval tokens — never PII at rest.
- Zero CapEx. Runs on standard devices. No hardware, no transfer of technology, no honeypot.
- White-label distribution. Partners can resell Sieve as a value-added reseller (VAR) across public and private markets.
Our inventions
Sieve's architecture and verification flows are protected by intellectual property filed with the USPTO. Below is a summary of the proprietary inventions that compose the platform.
1. Biovital proof-of-life (rPPG)
Remote photoplethysmography that reads the facial blood-volume pulse through a standard device camera, defeating photos, screens, masks and pre-recorded video. The signal is processed on device, in milliseconds, with no special hardware.
2. Vitality Registry Chain (VRC) — coercion detection
Detects duress by analyzing pulse variability and micro-expressions against an enrolled commitment baseline. A silent alarm triggers when physiological markers indicate the holder is being coerced.
3. Active dynamic liveness
The holder pronounces a random phrase drawn from millions of language-aware combinations, with 3D lip-sync verification — defeating deepfakes and injection attacks at the source.
4. Volumetric 3D mesh attestation
A 468-point facial mesh reconstructs the topological z-depth of every landmark to defeat presentation attacks (2D photos, screens, masks, prosthetics).
5. Self-Sovereign Interchangeable Digital Identity (SIDI)
A portable identity owned by the citizen, verified once by advanced biometrics, that flows across public and private services with a single sign-on — and is never reconstructed at rest without a live biovital match.
6. Tri-partite biometric-gated sharding
High-entropy sharding splits the cryptographic material between the user device, the relying-party domain and the Sieve guardian. No shard is reconstructable without a live Biovital Token — there is no centralized database to leak.
7. Non-custodial data exchange (Zero Data Liability)
Verified data travels end-to-end encrypted (AES-256) and returns only an approval token to the consuming system. Sieve is a trust protocol, not a database: there is no honeypot.
8. Sovereign screening shield
Real-time FaceScan cross-check against sanctions lists (OFAC, FATF), national wanted/missing registries and Interpol diffusion lists, with KYC/KYB/AML/PEP/UBO coverage in 190+ countries.
9. Anti-collusion vector matrix
Combines advanced biometrics with IP and GPS to block proxy bidders and coordinated fraud in tenders, financial onboarding and high-stakes transactions in real time.
10. Biovital forensic e-signature
A signature in Sieve is a live biological act, not a stored certificate. Each signature is bound to face + GPS + timestamp + immutable log — court-grade non-repudiation under eIDAS, ESIGN and UETA.
11. "Sign in with Sieve" — Pairwise OIDC IdP
A standards-compliant OpenID Connect identity provider that replaces social logins with a biometrically verified, pairwise (per-RP) identity — sovereign, granular and free of cross-site tracking.
12. Forensic invisible seal & breach autopsy
Every artifact carries a forensic seal that anchors to a Merkle-batched log on public chain, enabling autonomous breach detection and a public verifier (/verify/:hash) without exposing PII.
13. Ghost Email — privacy-preserving relay
A deterministic, revocable user_XXXX@mysieve.com alias with relay-node metadata stripping (pixels, IP leaks, fingerprints) and user-dictated routing.
14. Programmatic data settlement (Data Faucet)
An optional sovereign settlement layer in which the citizen monetizes consented data flows; the partner agency captures a revenue share without ever holding the data.
