The Japanese tech firm Fujitsu Laboratories has developed a blockchain-based solution for evaluating user credentials, identity and trustworthiness in online transactions, according to an announcement by Fujitsu.

As per certain reports, the solution uses user ratings, stored on a blockchain, to assign every user a “trustworthiness score.” Users purportedly rate each other when a transaction occurs and then the software evaluates this data to make a guess about users’ relationships with one another.

Other users can then see how high someone else’s trust score is before agreeing to a transaction, according to the announcement. Fujitsu is claiming that instead of traditional Decentralized Identification (DID) solutions the blockchain-based solution is better.

In some other solutions, a user is able to conspire with a bad-acting third party to falsify their records. Fujitsu is claiming that their solution avoids this kind of conspiracy by using a graph-based approach to understand users’ relationships.

Rather than depending solely on raw metrics and data, Fujitsu’s system reportedly looks to weed out collusion by looking at the graph of a users’ transaction relations. Even though a user shakes hands with a third party to make better their evaluation, the graph-structured relationships will reveal information such as the weakness of their relationships with other users, giving the system the ability to identify misrepresentations.

An announcement made by the company recently says that one of the things they want to achieve is to integrate this new solution into its blockchain-based Fujitsu Intelligent Data Service Virtuora DX Data Distribution and Utilization Service some time in the 2019 fiscal year.

As per certain reports, Fujitsu and tech giant Sony confirmed that they would partner to launch a blockchain-based pilot program in February. This collab aims to use blockchain technology to make school records and grades more trustworthy.

The pilot program will reportedly use Fujitsu’s educational platform Fisdom as a means to evaluate foreign students’ abilities, as compared with their stated certifications, while applying to a Japanese-language school.

This platform will collect data including test scores, Japanese conversational ability, and study time, and store them on a blockchain as a certificate. The examinators will be able to evaluate the language skills of individual students based on this highly reliable data, it will compare the certificate data on the blockchain with the educational certificates submitted by the students.
