Zero-knowledge proof
A cryptographic way to demonstrate a claim without revealing the secret information used to establish it.
In more detail
A zero-knowledge proof can show that a condition holds while keeping the underlying witness private. Some information can still be public, such as the claim being checked. Whether an app protects privacy depends on the whole design, including what it publishes alongside the proof.
