What’s DIDH?
(Decentralized Identity Data Hub)
To enable individuals have sovereignty over data, distribute data conveniently based on own choice, and minimize the information security risks, we need a new innovative data infrastructure completely differentiated from previous system.
DIDH(Decentralized Identity Data Hub) is a Web 3.0-based total data solution made by combining blockchain and IPFS-based encryption data sharing technology and distributed private key storage technology We realize SSI(Self Sovereign Identity)-based data economy by returning personal data from platform business to original owners so that individuals can control and manage their own data
