MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202621030391 A) filed by SSB Digital Private Limited, Ahmedabad, Gujarat, on March 13, for 'blockchain based verification and traceability of handloom & handicraft product.'
Inventor(s) include Indrajit Chanchal Simlai.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "A blockchain-based system and method for verification and traceability of handloom textile products is disclosed. The system employs a permissioned distributed ledger network implemented on Hyperledger Fabric, comprising peer nodes operated by state textile departments, handloom cooperative societies, and certifying authorities, with a RAFT-based consensus mechanism. A Cryptographic Product Hash Generation Module (CPHGM) computes a composite SHA-256 product hash H(P) from weaver HMAC-SHA256 identity, loom identifier, Geographic Indication zone coordinates, production timestamps, textile specifications, and dye batch parameters, creating an immutable blockchain-anchored digital fingerprint for each handloom product. Smart contract chaincode in Go programming language enforces weaver registration, production milestone attestation, quality parameter validation, GI compliance verification, and supply chain custody transfer without human intermediary intervention. IoT sensors integrated through a threshold-signature module anchor verified production telemetry on the blockchain. Consumer verification is enabled through QR-code / NFC-based interfaces supporting offline cryptographic merkle proof verification. The system integrates with UIDAI Aadhaar, DC Handlooms, and Textile Department APIs, providing a comprehensive anti-counterfeiting and traceability solution for India's GI-tagged handloom heritage."
