Japanese tech research firm Fujitsu Laboratories develops a blockchain-based solution that will evaluate user credentials, identity, and trustworthiness in online transactions, as per an announcement by Fujitsu on July 4.
As per the report, the solution will assign every user a “trustworthiness score,” based on user ratings, stored on a blockchain. The users will rate each other depending upon their transaction and the technology will evaluate the data to figure out the relationships with one another. Notably, other users could see the trust score before agreeing upon any transaction.
Fujitsu claims an advantage over other Decentralized Identification (DID) solutions that offer a class of solutions for identity and credential verification via third parties. In certain similar solutions, a user can reportedly conspire with a bad-acting third party to falsify their records. As per Fujitsu, their solution could avoid such conspiracy through a graph-based approach to understand users’ relationships.
Fujitsu would not solely depend on raw metrics, the system will purportedly look forward to weeding out collusion by looking at the graph of a users’ transaction relations:
“Even if a user colludes with a third party to improperly raise their evaluation, the graph-structured relationships will reveal information such as the weakness of their relationships with other users, giving the system the potential to identify misrepresentations.”
Fujitsu further elaborated over one of its goals in the announcement, i.e. 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.
In February, Fujitsu confirmed a collaboration with the tech giant Sony to launch a blockchain-based pilot program, that will employ the technology to make school records and grades more trustworthy.
The new pilot program will use educational platform Fisdom as a means to evaluate foreign students’ abilities in comparison to their stated certifications, while applying to a Japanese-language school:
“The course platform will collect data including test scores, Japanese conversational ability, and study time, and store them on a blockchain as a certificate. Human Academy […] will be able to accurately grasp the language ability of individual students based on this highly reliable data, by comparing the certificate data on the blockchain with the educational certificates submitted by the prospective students.”
