"Self-sovereign Identity" (SSI) in digital identity management refers to a model where individuals have complete control over their own digital identities. Users create, manage, and share their identity information without relying on centralized authorities or third-party intermediaries. This fosters data privacy and empowers users to verify their identity through decentralized technologies, such as blockchain. SSI enhances trust and efficiency in online interactions, enabling users to securely share credentials while minimizing the risk of data breaches.
