FOAB E-Traceability: Tamper-Evident Aquaculture Value Chain
Every fish harvest tells a story. The FOAB E-Traceability system transforms on-farm feeding, water quality monitoring, and hatchery genetics into cryptographically signed digital records that verify provenance for processors, retailers, and consumers.
The 4-Stage Cryptographic Value Chain
How production milestones are recorded, cryptographically linked, and permanently archived.
Hatchery & Genetics
Spawning dates, wild riverine broodstock genetic source, spawn batch ID, and licensed hatchery registration numbers are established.
Pond Stocking
Release count, nursery pond depth, lime conditioning pre-treatment, and initial fingerling weight recorded under member signature.
Feeding & Telemetry
Registered floating feed batch brands, probiotic schedule, dissolved oxygen logs, and periodic average body weight samplings.
Harvest & QR Seal
Final yield, transport vehicle dispatch, and tamper-evident QR code generation sealed with the association HMAC-SHA256 secret.
Why Cryptographic Verification Matters
Unlike paper certifications that can be duplicated or forged, FOAB records are immutable. Each event hash mathematically incorporates the previous event hash, preventing retrofitting of production records.
QR codes encode a cryptographic signature verified dynamically by the FOAB verification server.
Public verifications show district, species, and hash-chain proof without exposing sensitive operator deeds or phone numbers.
If an operator misrepresents a batch, secretariat staff can revoke or rotate the QR key immediately in real-time.
