In Self-Sovereign Identity: Decentralized digital identity and verifiable credentials, you’ll learn how SSI empowers us to receive digitally-signed credentials, store them in private wallets, and securely prove our online identities.
In a world of changing privacy regulations, identity theft, and online anonymity, identity is a precious and complex concept. Self-Sovereign Identity (SSI) is a set of technologies that move control of digital identity from third party “identity providers” directly to individuals, and it promises to be one of the most important trends for the coming decades. Personal data experts Drummond Reed and Alex Preukschat lay out a roadmap for a future of personal sovereignty powered by the Blockchain and cryptography. Cutting through technical jargon with dozens of practical cases, it presents a clear and compelling argument for why SSI is a paradigm shift, and how you can be ready to be prepared for it.
About the technology
Trust on the internet is at an all-time low. Large corporations and institutions control our personal data because we’ve never had a simple, safe, strong way to prove who we are online. Self-sovereign identity (SSI) changes all that.
