InfraBlockchain-based Decentralized Identifiers (DID) technology
returns the sovereignty of identity & personal data back to individual users
In the current internet structure, each service requires users to create centralized, dedicated IDs and independently
manages their data. As a result, users on the internet face the inconvenience of having to remember and manage
hundreds of service-specific ID/passwords, while all personal data is collected and owned by service providers.
Alternatively, blockchain-based DIDs (that are wholly owned by individuals and objects) can be created from mobile devices
and IoT devices. Verifiable data (VC, Verifiable Credentials) that are digitally signed by trusted entities are
then issued to the user's DID, allowing individuals to own such data.
These verifiable data, instead of going through central servers, can be submitted to a verifier (using VP, Verifiable Presentation) in a way that protects privacy, and the integrity of the data can be verified using blockchain. DID and VC are the core technology that constitutes Web 3.0,
where individuals have complete sovereignty over their identity and data on the Internet.
InfraDID Method Specification (W3C)
DID and VC technology are the web standards approved by the World Wide Web Consortium (W3C).
The InfraBlockchain-based DID specification (did:infra) is a web standard-compliant DID method registered in the W3C DID Spec Registry.
The World's First Blockchain-based Mobile Vaccine Pass
The mobile vaccine pass COOV system, which was developed using InfraBlockchain and InfraDID technology, was officially
adopted by the Korean government, used by more than 43 million people, and achieved interoperability with countries
such as EU members and Singapore, and used in more than 120 countries. The COOV system, which issued hundreds of millions of
certificates and processed more than 30 million blockchain-based certificate verifications per day at the peak of the pandemic,
has become an unprecedented case in the history of blockchain to provide blockchain-based practical service on a national level.
Personal Blockchain Cloud
Blockchain ID(DID)-based, Web 3.0 Technology
for Personal Data Management and Distribution
Breaking away from the current Web 2.0 service structure which heavily involved the use of
centralized servers, Web 3.0 services using P2P(Peer to Peer) network of Personal Blockchain Cloud Nodes(PBC Nodes)
empower the users on the internet to have ownership of their ID and data,
rather than giving them away to each services.
A blockchain-based ID (DID, Decentralized IDentifier) generated on an individual's mobile device,
therefore not tied to a specific platform, is used as a web service user ID and a blockchain account.
Personal data such as messages, documents, photos, videos, and certificates are stored within
mobile wallets and personal cloud servers, and can be directly presented to other users and businesses.
By sharing their PBC-managed personal data, users can be rightfully compensated from those looking to access such data.
DID IC Chip Technology
DID IC Chip is Blockchain Labs' patented technology to embed a blockchain ID (DID) in an IC chip,
so that the IC chip or the chip-attached physical object can act as a blockchain node (DID Agent).
The IC chip can create and manage a blockchain ID (DID), store certificate data (VC) issued by trusted authorities,
and sign blockchain-based cryptographic signatures on its own with this technology, it is impossible
to create replicas and counterfeits of the chip-attached physical object. The NFC wireless communication
interface enables the IC chips to interact without direct contact.
DID IC chips can be installed on credit cards, luxury brand products, artworks, IoT-based electronic products, etc.
to enable various services such as identity authentication, payment, product authentication, supply chain management, and advertising.
