Sony and Fujitsu have developed a blockchain-based encrypted database platform for educational proficiency documents. The database is claimed to prevent frauds related to Japanese language proficiency tests, as foreign students usually tend to attain fake documents to receive resident status in Japan.

The encrypted database has been developed by combining Fujitsu’s online learning system with the blockchain platform built by Sony Global Education Inc. Using the blockchain-powered platform, certificates can be verified and authenticated with data registered on the blockchain, the companies said.

As per sources, the duo will deploy the platform for real-world use in April, after conducting its trial at Human Academy Co. in March. The academy runs Japanese language schools across various cities in Japan, including Osaka, Saga and Tokyo.
