Independent research into three-factor entropy-fused geo-fenced encryption. Patent application filed covering the full architecture.
Coverage Summary
Three-factor entropy-fused geo-fenced encryption: physical location signal context, hardware attestation, time-window constraints, and post-quantum key establishment. Full claim details are available to qualified parties under NDA.
Evidence Record
Conception documented July 2025 (2,930-line prototype). Production codebase of 50 modules committed April 2026 with OpenTimestamps Bitcoin blockchain anchoring on the same date. GPG-signed commits with SHA-256 hashes provide a tamper-evident prior-art and conception timeline.
Important
Patent pending, not granted. This page does not disclose the full claim text. Technical details are available to qualified parties under NDA.
Independent Conception
GFAE conceived independently. 2,930-line prototype committed, establishing the earliest evidence record for the invention. Sole inventor: Dhruv Saini.
Architecture & Implementation Guides
Full technical architecture formalised. Implementation guides produced covering the three-factor entropy fusion pipeline: ML-KEM-1024, GNSS signal context, TPM 2.0 PCR attestation, and HKDF-SHA-512 key derivation.
Production Codebase — Blockchain Anchored
Production codebase of 50 Python modules committed. OpenTimestamps Bitcoin blockchain anchoring applied on the same date (April 2026). GPG-signed commits with SHA-256 hashes provide tamper-evident evidence record.

| Reference / Category | GFAE Distinction |
|---|---|
US9940477B2 — Spychatter (2018) Static GPS Geo-fencing | GFAE uses live satellite signal entropy (SNR values, HDOP, constellation geometry) that requires physical presence. Coordinate values alone cannot reproduce the key material. |
US11962694B2 — Microsoft (2024) Environmental Sensor Entropy | GFAE combines post-quantum shared secret, live GNSS signal-quality context, and TPM 2.0 PCR attestation through a domain-separated HKDF-SHA-512 pipeline — a distinct three-factor entropy fusion architecture. |
NISTIR 7904 — NIST (2015) TPM Access Gating | GFAE uses TPM 2.0 PCR quotes as one entropy contributor in a multi-factor fusion pipeline, not as a standalone gate. The PCR value participates in key derivation material, not merely in an access decision. |
US9680827B2 — CyberArk (2017) Geo-fenced Key Validity | GFAE does not gate an existing key. It makes the key impossible to re-derive outside the authorised boundary. The cryptographic boundary and the physical boundary are mathematically the same object. |
US11082224B2 — Rambus (2021) Coordinate-Derived Keys | GFAE uses per-satellite SNR values, HDOP, and constellation geometry — measurements that require physical presence and cannot be reverse-engineered from coordinate values alone. |
EP3720046A1 — Microsoft (2020) TPM Certificate Gating | GFAE integrates TPM 2.0 PCR quotes as entropy material in a three-factor key derivation pipeline, not as a credential presentation mechanism. |
US9256742B2 — Intel (2016) Infrastructure Geo-location Assertion | GFAE derives location context from the device's own live GNSS signal measurements, not from operator assertion. The physical boundary is device-verified, not infrastructure-declared. |
Prior art assessment based on current review. GFAE is patent pending (GB2610661.7). This table does not constitute legal advice or a legal conclusion of novelty.
This assessment is based on current review and does not constitute a legal conclusion of novelty or patentability. GFAE appears distinct from identified prior art in the combination of factors described. Patent pending | GB2610661.7.
