Significance of Solution
LEDGIS, A Decentralized Data Platform for Web 3.0
“SSI Data Open Ecosystem with Various Services Connected Centering on Individuals” Create Huge Added Value by Distributing Data in The Safest and The Most Convenient Way.
LEDGIS, A Decentralized Data Platform for Web 3.0
Decentralized Platform Distributes Benefits to All Participants
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
Features of Decentralized Platform, LEDGIS
SSI-Based Data Distribution
Users hold SSI-based data sovereignty &Users can distribute data conveniently based on their choice
Activity information generated during service use can be monetized based on own choice
Prevention on Illegal Use of Other’s Name
Each wallet is connected to each individual’s bio-data to prevent illegal use of other’s name
Bio-data can be used as login password Others who have different bio-data cannot login
Privacy Protection + Reliability
Protect privacy by ensuring reliability on part of the data fragment information
All or part of data generated by service provider can be sent, renewed, and recovered. Data receiver can check the verification status at all times
Innovatively Simplified Authentication Procedures
Quick bio-data login without card/cell phone
Anti-Loss/Anti-Theft of Key
DIDH Wallet supports biometric authentication-based key lock/key unlock to prevent any theft. The wallet can be useful in business that empathize personal identification
When key is lost, key can be recovered by using biometric authentication
Decentralized Data-Based Security
Applied with distributed data storage technology so that whole data cannot be taken during hacking
Zero knowledge proof system (W3C standard compliance) to protect privacy and expose only part of the sensitive information such as personal information
DIDH Network Diagram
Various partners participate as blockchain network’s nodes and guarantee data security and reliability. Since participation and withdrawal of some nodes don’t influence on overall network reliability, system integrity can be maintained at all times
