Microsoft has revealed its plans to use blockchain distributed-ledger technologies to securely store and manage digital identities, starting with an experiment using the Microsoft Authenticator app. From a report: Microsoft reckons the technology holds promise as a superior alternative to people granting consent to dozens of apps and services and having their identity data spread across multiple providers. It highlights that with the existing model people don't have control over their identity data and are left exposed to data breaches and identity theft. Instead, people could store, control and access their identity in an encrypted digital hub, Microsoft explained. To achieve this goal, Microsoft has for the past year been incubating ideas for using blockchain and other distributed ledger technologies to create new types of decentralized digital identities.
