Blockchain Customer Identity Management — Self-Sovereign Identity Implementation

Self-sovereign identity (SSI) lets users control their own identity credentials rather than relying on centralized providers (Google, Facebook login, government databases). Here is the implementation framework.

Complete Comparison

Self-sovereign identity uses W3C Verifiable Credentials, DID (Decentralized Identifiers) on blockchain, and zero-knowledge proofs for privacy-preserving verification. Users hold their credentials in wallets, and verifiers receive only cryptographic proofs — not raw data. This reduces data breach risk by shifting from "one giant database" to "many individual wallets."

Answers

How does self-sovereign identity reduce data breach risk compared to traditional identity systems?

Traditional identity systems centralize PII in one database (a honeypot for hackers — see Equifax 2017, exposing 147M SSNs). Self-sovereign identity distributes credentials to individual user wallets, with only cryptographic proofs (not raw data) shared with verifiers. A breach of any single verifier doesn't expose other users' data because each user holds their own credentials. The attack surface shifts from "one giant database" to "many individual wallets," which is harder to exploit at scale.
