Every day the world is becoming more digital, which means we increasingly need an effective, trusted, and convenient way to prove our identity as we interact with digital services from governments, retailers, and other service providers. We can no longer easily use things like a driver’s license in a digital environment.

A digital equivalent that could be held by individuals and accepted by all service providers would make it much easier and safer to do business online. Some digital national IDs can be used to access some government services, but they are not widely accepted.

There is a need a universal digital ID that can be used to access all digital services, without having to enter personal identity information for every single service and having to trust every service provider to keep that centralized personal information safe.

Decentralized Identities, which are a type of digital identity that captures a set of attributes, identifiers, and credentials relating to a specific person or thing, are a viable alternative that could be used by all service providers, but with added user convenience and without the security risk.

Decentralized identities are stored in a decentralized architecture to decouple the ID from the issuer and the service it is being used to access.  Because decentralized IDs are stored in a digital format, they need to be cryptographically secure so that they cannot be tampered with, duplicated, or stolen.

For decentralized IDs to work, there needs to be a holder of identity credentials that are typically stored in a digital wallet or on a smart device, credentials that make specific claims about the identity holders, and issuers who are responsible for each credential.

These credentials need to be verifiable credentials, which are tamper-evident claims that can be cryptographically verified and include proof of who issued it. Verified credentials can contain a decentralized identifier (DID), which is globally unique and cryptographically verifiable.

These cryptographic elements are then anchored to a blockchain or other decentralized ledger so that when credentials are presented, they can be verified by the service provider in the same way that a driver’s license would be verified by a car rental company.

The concept of a Self-Sovereign Identity (SSI) is closely related. An SSI on the blockchain is a permanent ID that is managed by the person to whom it belongs, but aspects of that identity can be shared with individuals, organizations, or agencies when relevant.

SSIs are decentralized and encrypted, and are typically stored on devices under control of the identity owners. Identity data is provided when the identity of the owner needs to be validated, but without relying on a centralized database.

Decentralized identity, therefore, provides a way of accessing services without creating centralized stores of personal information. Instead, individuals hold their own identity credentials, which they can hold in a digital wallet and present to whichever services they would like to access.

Decentralized Identity offers compelling advantages for organizations to benefit from increased identity assurance levels, interact securely and with higher confidence with partners, suppliers, and other ecosystem members, and reduce the administrative load during onboarding or ongoing verification and/or validation of credentials.

However, organizations need a way to make decentralized identities interoperable with their current systems and to enable access management policies work with them. There are also other challenges that need to be addressed such as revocation of credentials and scalability, but these are being solved. In the meantime, organizations should be gearing up for the coming new era of decentralized digital identity so they will be ready to use it as soon as the wider ecosystem is up and running.

Proof of concepts and first customer experiences are demonstrating the many ways that decentralized identity can offer optimizations, savings, and advantages for security and privacy.

As mentioned above, the Global Assured Identities Network (GAIN) proposes an identity network that would allow any global organization to utilize verified identity attributes. To understand what GAIN is, what use cases it serves and who may be interested, have a look at this Leadership Brief entitled: GAIN Explained.

To find out how to go about enabling decentralized identity and how it can fit into an Identity Fabric, have a look at this Leadership Brief: Guide to Implementing Decentralized ID.

As shown in the above-mentioned Leadership Brief, establishing an Identity Fabric is one of the ways of enabling the use of decentralized identity. To find out more about his concept and the vendors that support it, have a look at this Leadership Compass on Identity Fabrics.

For further perspectives on technologies that support the use of decentralized identities, have a look at these Market Compasses on Providers of Verified Identity and Decentralized Identity: Blockchain ID & Self-Sovereign Identity Solutions, and this Buyer’s Compass on Decentralized Identity for key criteria and questions to help select an appropriate vendor.

For a broader perspective on decentralized identity, have a look at these Leadership briefs entitled: The Business Value of Decentralized Identity, What to Consider When Evaluating Decentralized Identity?, and Blockchain ID & Self Sovereign Identity.


For insights into consuming decentralized Identities in different sectors, have a look at these Advisories on fostering digital business innovation in the Healthcare, Utilities & Energy, and Finance sectors.

To find out where decentralized identity fits, in terms of how businesses need to evolve their identity management strategies to become well-placed to meet existing, new, emerging, and future requirements, have a look at this Advisory Note on the Future of Identity Management.

This Advisory on Redefining Access Governance: A broader perspective once again refers to the Identity Fabric concept and how it relates to implementing decentralized identity.
