Japanese technology company Fujitsu Laboratories has launched a blockchain based digital identity exchange technology. In addition to enabling businesses and individuals conducting transactions online to confirm the identities of other parties, the technology will also gauge the “trustworthiness” of credentials. This will be through mutual evaluation of transacting parties, examination of historical data and networks of past transactions to produce a rating and reputation of each party. The rating and reputation data will be in a distributed ledger, assuring its security. However, the system will only disclose necessary information. The company also described the technology as user friendly with graphics to offer visualisations of user relationships.
