Zero-Knowledge Proofs vs Hash Verification: What They Mean

Security terms describe different mechanisms. A zero-knowledge proof, encryption and a hash comparison are not interchangeable simply because each uses cryptography.

What a zero-knowledge proof means

NIST's definition describes a scheme in which a verifier can be convinced a statement is true without learning additional information about it. A vendor's broader “zero-knowledge architecture” label needs separate examination of keys, metadata, recovery and service access.

Questions to ask about a private workflow

• Who holds the keys and can recover access?
• What content or metadata reaches the service?
• What can a shared recipient view, download or forward?
• What independent technical evidence supports the claim?

Do not equate a QR check with a zero-knowledge proof

TrueConsent offers tamper-evident records and QR verification. Those capabilities alone do not establish a zero-knowledge proof system or provider-blind storage. Read the privacy policy and request appropriate evidence for any privacy requirement your workflow depends on.
