Hitachi and KDDI develop blockchain fingerprint verification
In plainer English, the joint venture aims to launch a blockchain-based payments system that can verify users’ identity using their fingerprints.
Built by Hitachi using distributed ledger technology from the Hyperledger Fabric platform, the system will be integrated into KDDI’s coupon system and use fingerprints as transaction validators.
“Hitachi’s proprietary technology, which combines biometric authentication infrastructure with block chains, enables automatic generation of electronic signatures with characteristic data of biometric information with low risk of theft and leakage,” the company said in a statement on its website.
As consumers sign up to use the system they will register their coupon credits and submit their fingerprint. The credits and biometric information are then encoded onto the blockchain so customers at participating retailers just verify their identity on a fingerprint reader that disseminates the transaction request to the network to be settled.
Hitachi has been active in blockchain research in the retail sector in the last year or so. Last year it said it was developing a distributed ledger platform to help manage supply chains.
