Sovereign Identity
Definition
Self-sovereign identity (SSI) is a model for managing digital identities in which individuals have sole ownership and control over their personal data. It allows users to control what information they share and with whom, without relying on a central identity provider.
Why It Matters
SSI aims to fix the problems of the current identity model, where our data is controlled by large companies like Google and Facebook. It gives users control over their own digital identity, enhancing privacy and security.
Contextual Example
With SSI, you could have a digital wallet on your phone containing verifiable credentials, like your driver's license or university degree. To prove you are over 21 to enter a bar, you could reveal just that single fact ("is over 21: true") without revealing your name, address, or exact birthdate.
Common Misunderstandings
- SSI often uses blockchain technology and verifiable credentials to work.
- It is a key concept in the vision for a decentralized Web3.
