In the future, biometric technology will be widely used for identity management. Biometric authentication has been closely linked to the concept of identity, as certain biometrics can identify you among a certain set of users (as employees or citizens). In this case, identity is the way you “assert” rights, membership, and ownership of property or data.
Hitachi from Technology Media Telecom demonstrated biometric blockchain authentication through Ledger Insights 2 years ago. The retailers included include the telecommunications company KDDI’au SHINJUKU’s flagship store and the branch of Mr. Donuts. The demonstration is just an employee pilot and uses the KDDI coupon system. Biometric users first register and use their fingerprints for identification. It uses Hitachi’s own biometric infrastructure (PBI).
Hitachi does not store biometric data. Instead, it uses fingerprints to create digital signatures through public-key cryptography. Signature creation is a one-way conversion with fluctuations, so it can not be repeated. Therefore, if the identity is recreated, the variations will be slightly different, creating a different signature. How it works when a user receives coupons, will be linked to the person’s identity. The user does not have to show the coupon but puts his finger on the dealer’s identity verification gadget. You can use coupons without using a smartphone. This allows users to use coupons faster and retailers to use them more efficiently.
Coupon usage data is stored in the Hyperledger Fabric blockchain, which can reduce reconciliation costs. This also makes it very difficult to manipulate coupons. Each participant in the blockchain will host a node and therefore a copy of the shared information.

But where will the declaration of identity be? Today, the government issues identity statements in the form of documents that are difficult to falsify, including birth certificates, driving licenses, and passports. About a dozen companies are actively involved in identity solutions, and these agencies are independent of all central authorities, such as authorities or representatives of companies or entities. All of these solutions include identity declarations available in the blockchain to achieve decentralization, enforceable contracts, secure encryption, and consensus.
