This has sparked a debate over centralized versus decentralized identity systems. Many privacy advocates now champion "Self-Sovereign Identity" (SSI), a model where individuals control their own data via blockchain technology, sharing only what is necessary without relying on a central authority.

The most secure systems, often referred to as "Multi-Factor Authentication," combine these pillars to ensure that even if one element is compromised, the identity remains protected. Challenges: Security vs. Privacy 8 : Proof of Identity
