We approach the problem of digital identity starting from a human rights perspective, asserting that individual persons must be allowed to manage their personal information in a multitude of different ways in different contexts and that to do so, each individual must be able to create multiple unrelated identities. Therefore, we first define a set of fundamental constraints that digital identity systems must satisfy to preserve and promote human rights. With these constraints in mind, we then propose a decentralised, standards-based approach, using a combination of distributed ledger technology and thoughtful regulation, to facilitate many-to-many relationships among providers of key services. Our proposal for digital identity differs from others in its approach to trust: by avoiding centralisation and the imposition of trust from the top down, we can encourage individuals and organisations to embrace the system and share in its benefits. %J Frontiers in Blockchain %K digital identity, certification, identification, trust, privacy, anonymity %L discovery10074541 %V 2
