Self-Issued Verifiable Credentials Simplified
What are Self-Issued Verifiable Credentials?
Self-issued verifiable credentials are digital certificates that individuals or machines can create and manage themselves. Unlike traditional credentials, which often require third-party validation, self-issued credentials offer a way for users to assert their identity securely and privately.
Why Use Self-Issued Verifiable Credentials?
- Control: Users have full control over their information, deciding what to share and with whom.
- Privacy: Reduces the risk of personal data exposure since you can share only necessary details.
- Cost-Effective: Eliminates the need for intermediaries, reducing costs associated with verifying identities.
How Do They Work?
Self-issued verifiable credentials work through a digital signature mechanism. Here’s a simple breakdown of the process:
- Creation: The user or machine generates the credential and signs it digitally.
- Storage: The credential is stored securely, often in a digital wallet.
- Sharing: When needed, the user shares the credential with a verifier.
- Verification: The verifier checks the digital signature to confirm the credential's authenticity.
Real-Life Example
Imagine a student applying for a job. Instead of providing paper transcripts, the student can use a self-issued verifiable credential that contains their grades and course completion status. The employer can verify the information without needing to contact the school.
