Fujitsu Develops Digital Identity Technology to Evaluate Trustworthiness in Online Transactions

Fujitsu Laboratories Ltd. has developed a digital identity exchange technology that makes it possible for individual users and service businesses involved in online transactions to confirm the identity of other parties in transactions.

The rapid advance of digitalization in recent years has been accompanied by a dramatic rise in the number of online transactions in which users cannot see one another face to face, making it difficult to judge the credibility of the other party and leading to heightened concerns around trust. With reports of fraud and instances of people falsifying personal credentials like work history and professional qualifications growing increasingly prevalent, ensuring the circulation of high-quality, reliable identification data poses an urgent challenge to users and businesses alike.

To address this, Fujitsu Laboratories has developed technology based on a Decentralized Identification (DID)(1) utilizing blockchain that analyzes the risk of falsification and the trustworthiness of the other party's personal credentials when a user conducts a transaction online. The new technology achieves this through a mutual evaluation of the users when a transaction occurs, and by inferring the relationships between users based on past transaction data.

Fujitsu's new digital identity exchange technology promises a future in which people can enjoy online services more safely, offering user-friendly features including graphics to visualize the relationships between users, as well as a unique "trust score" that make it easier to determine each user's trustworthiness before starting a transaction.

Background

In recent years, there has been an increase in new forms of business based on trust between people or companies, including sharing and matching services. In these sorts of digital businesses, it remains crucial to accurately convey the identi./he other party in the transaction. There are now ongoing discussions around the use of blockchain technology in these kinds of transactions as a form of decentralized identification that accurately discloses each party's identity to the other parties, as guaranteed by an impartial third party.

Issues

DID is a system in which a third party guarantees the accuracy of a givenindividual's identity and personal credentials. If a service business or user conspires with a third party acting in bad faith, however, it is possible to falsify a person's history or credentials, creating the risk that this falsified information will spread very widely without being discovered. Moreover, as the number of users who utilize these services increases, it becomes more difficult for users or a third party to grasp what sort of people the other parties are, increasing the possibility of maleficence. This necessitates a system whereby users can evaluate for themselves the truthfulness of the identity of the other parties in the transaction.
