An organization is deploying a secure system where users must prove their identity without revealing any other unnecessary information. Which cryptographic concept allows for this selective disclosure of information?

  • Biometric Authentication
  • Public Key Infrastructure (PKI)
  • Two-Factor Authentication
  • Zero-Knowledge Proofs
The cryptographic concept that allows for selective disclosure of information without revealing unnecessary details is 'Zero-Knowledge Proofs.' In this technique, a prover can demonstrate knowledge of a secret without revealing the secret itself, ensuring privacy and security.
