The time is ripe for digital passports in healthcare

The use of the EMPI as an accurate patient directory is a critical tool in the creation of the patient passport. But in order to transcend barriers between health systems, we need a portable, privacy-preserving way of dealing with patient identity beyond the boundaries of individual healthcare organizations.

That’s where blockchain comes in. Much more than just the backbone of cryptocurrency, blockchain can be used as a public ledger to store and manage the life cycle of decentralized identifiers (DID). These globally unique DIDs are used as the anchor points for verifiable health credentials, such as insurance cards, test results, and vaccination records. Using this concept, a trust network between issuers, holders and verifiers of credentials can be established. With these features, blockchain could be a game-changer for identity management and verification at key stages where patient data errors often occur—during enrollment and at registration, all while maintaining strict patient privacy.

A Beginner’s Guide to Decentralized Identity

Instead of a centralized issuer and storage, DID solutions spread out the issuance and storage of information that make up an identity across various entities.

This information could include a user’s height, weight, eye color, favorite Spotify playlists, and even social security number. Decentralized identity solutions are very comprehensive and sometimes offer incentives to attract new users, similar to how airline mile points can be earned for signing up for new credit cards.

Instead of storing your personal information on a single server, blockchain technology encrypts this data and spreads it across multiple nodes. Usually, this encryption comes in the form of a two-key password called a private and public key. The only way to access the personal information in question is by matching the two keys.

Blockchain technology used for commercialization of mobile driver’s license service

The demonstration will be based on the ministry’s experience of creating a digital identification service for government workers. The app ID card service used a DID system instead of a centralized identity (CID) system in which the host can track and monitor users. The DID system ensures users’ self-sovereign over privacy. Users can choose to share their identity or not.

The ministry thinks the blockchain-based license will pioneer the global personal digital identity authentication market. “Starting with the digital driver’s license service, the government and private companies will eventually have to provide various identification services that integrate mobile ID cards,” it said.

Understanding the Verifiable Credentials (VCs)

Verifiable Credentials heavily utilize Decentralized Identifiers to identify people, organizations, and things and to achieve a number of security and privacy-protecting guarantees. They are issued and cryptographically signed documents, intended to be understood by computers rather than people.

A user identifier that is:

  • In digital form
  • Able of communication with decentralized ledger
  • A property of its owner that is stored in a wallet
  • Contains the DID data string that pairs the user’s public address with a user’s public key stored on a blockchain
  • Representing user ID, diploma, and many others

Decentralized Identifiers (DIDs) – A Deeper Dive

DIDs enable you to reference subjects in a decentralized way. DIDs can be resolved to DID documents. DID documents allow the controller to prove they are/own the subject. A blockchain-based company generates these documents for all its accounts, which have done at least one TX. These accounts are created by publishing a certificate, which is related to a DID, thus making a connection between the DID and real-world identity. DIDs can be part of Verifiable credentials (VC), which can be used for multiple cases all around the world.

Microsoft Launches Decentralized Identity Platform ION On Bitcoin’s Blockchain

The ION Decentralized Identifier (DID) will utilize the Bitcoin blockchain to authenticate online IDs.

Essentially, ION will use the same logic as Bitcoin’s transaction layers to validate a user’s identity. According to ION, all the IDs will be tied to Bitcoin’s blockchain using the InterPlanetary File System (IPFS) protocol, and nodes will be able to process 10,000 ID requests in a single transaction.
