It allows users to reclaim their privacy and control over their digital identities and data while at the same time offering standard compliant protocol support through OpenID Connect.\nIn this lecture, we present the motivation behind the technology and the technical foundations.\n\n\u003cp\u003e\nToday, users are often required to share personal data, like email addresses, to use services on the web. As part of normal service operation, such as notifications or billing, services require access to -- ideally fresh and correct -- user data.\nSharing attributes in the Web today is often done via centralised service providers to reduce data redundancy and to give services access to current, up-to-date information even if the user is currently offline.\nAbuse of this power is theoretically limited by local laws and regulations.\nBut, the past has shown that even well-meaning identity providers struggle to keep user data safe as they become major targets for hackers and nation state actors while striving for monetising anonymised statistics from these data.\nWe advocate for a new, decentralised way for users to manage their identities for the following reasons:\n\u003c/p\u003e\n\u003cul\u003e\n  \u003cli\u003e The current state of omniscient identity providers is a significant threat to the users' privacy.\u003c/li\u003e\n  \u003cli\u003eUsers must completely trust the service provider with respect to protecting the integrity and confidentiality of their identity in their interest.\u003c/li\u003e\n  \u003cli\u003eThe service provider itself is facing substantial liability risks given the responsibility of securely managing potentially sensitive personal data of millions of users.\u003c/li\u003e\n\u003c/ul\u003e\n\n\u003cp\u003ere:claimID is
