Explore how KeyFT leverages Trust-as-a-Service (TaaS) to secure field data through cryptographic validation and multi-layered sensor attestation.
Built on Cloudflare Workers and D1 Database for global zero-latency performance. Ensures data is processed in a distributed manner without any Single Point of Failure (SPOF).
Runtime: Cloudflare Workers
Storage: D1 SQLite (Edge)
Security: JWS Attestation
Every mission report is cryptographically signed using JSON Web Signature (JWS). This ensures that data remains tamper-proof and immutable during transit.
{ "alg": "HS256", "typ": "JWT", "kid": "worker_v4_anchor" }
Integrated biometric detection ensures physical human presence. The system verifies facial landmarks and liveness in real-time before the submission sequence is unlocked.
Verify: NeuralMatching(Face_Hash, Profile_DB) === true;
For privacy and efficiency, the protocol automatically deletes raw reports 5 days after mission completion, retaining only the permanent verification hashes.
if (currentDate > expiryDate + 5d) { purge(raw_data); keep(hash); }
Beyond standard GPS, KeyFT calculates radial distance server-side to prevent "Fake GPS" or coordinate spoofing on the client/worker browser side.
const dist = serverSideHaversine(client_loc, target_loc);
if (dist > radius) throw Error("UNAUTHORIZED_LOC");
Engineered to verify tree planting or social initiatives. Funds or payroll are only released if all sensor requirements (Photo + GPS + Biometric) are fully met.
