Centralized ways of proving identity may soon have an expiration date.
A lofty claim, perhaps, but the idea is arguably bolstered by the launch this week of a functioning blockchain prototype this week built by Microsoft and Accenture. The technology could one day allow users to accumulate verified information about their identity in a profile they control.
Instead of permanently handing over that information to a university, a healthcare provider or a potential employer, the owner of the identity could choose exactly who gets access to what data – and for how long.
The global head of Accenture’s capital markets blockchain practice, David Treat, explained in the first live demo of the prototype how any number of identity sources can be aggregated under a single profile.
Speaking on stage at the ID2020 conference hosted earlier this week, Treat explained:
“We’re not moving the data, we’re indexing this information. We’re putting it into the individual’s hands.”
Powered by a private version of the ethereum blockchain, the prototype runs on Microsoft’s Azure cloud computing platform, according to an Accenture statement, and sets out to comply with principles established by the Decentralized Identity Foundation, co-founded by Microsoft.
Under the hood
Instead of reinventing how identity itself is proved, the prototype, developed with assistance from managed service provider Avanade, acts as a cryptographically protected store of data verified by existing identity providers.
Yet, when the allotted time expires, any access to the identifying data is permanently revoked, meaning profiles do not “accumulate” over time.
The distributed ledger is designed to be maintained by participating parties, while simultaneously preventing personally identifiable information from being viewed by those parties.
Though the demo was conducted using a smartphone user interface, Treat said any number of formats could eventually be employed.
Should the prototype be released to the public, the network of users will likely employ Accenture’s Biometric Identity Management System to gain initial access, according to a company statement. The service has already been used in the field by the United Nations High Commissioner for Refugees (UNHCR) to enroll 1.3 million refugees in 29 countries.
“The platform we used allows for the capture of any form of biometric identity, whether that’s voice, or face, or whatever,” Treat said.
