Tech giant Samsung Electronics is joining six other major South Korean firms to develop a blockchain-based certificate and ID authentication network.

Announced on Sunday and reported by CoinDesk Korea, the other founding firms include mobile carriers SK Telecom, LG Yuplus and KT, two banks – KEB Han and Wooriand – and government-founded securities infrastructure provider Koscom.

The service will provide a "self-sovereign" authentication solution that does away with middlemen services and allows users to verify their identity or qualifications over a blockchain, keeping more control of their own personal information. Individuals can store their data on a smart device and submit only the data they choose when certification is required.

Tech-wise, the deal will see the firms develop the service based around a consortium blockchain model, with participating companies operating network nodes using their own servers.

The system will see a beta test by the end of 2019 and a decision on whether to commercialize the offering will be made in the next year, the report says.

Initially, the service will be applied to the issuance and distribution of graduation and other certificates from major universities in Korea, as well as to Koscom's platform for unlisted startup stocks.

A plan is being considered for the three telcos to use the system for their career recruitment process.

Mobile ID certification is expected to simplify the issuance and submission of various certificates and help companies ensure the digital have not been falsified – all in real time.

Ultimately, the firms indicated they may expand the service to other areas by encouraging more companies to participate, with potential use cases across digital signatures, user authentication for telecom and banking, healthcare and insurance certification, and club memberships.

Notarization, proof of content and online logins were also listed as potential areas that could be addressed by the network.
