Age Verification
How to use Zipwire Attest to verify your age for age-restricted services and platforms while maintaining privacy through selective disclosure technology.
What is Age Verification with Selective Disclosure?
Age verification with selective disclosure (also known as selective reveal, minimal disclosure, or privacy-preserving verification) allows you to prove your age to access age-restricted services, platforms, or content without revealing your full date of birth or other personal information. This is particularly useful for services that need to comply with age-related regulations while respecting user privacy.
Selective disclosure technology enables you to share only the specific information needed - like proving you're "over 18" - while keeping all other personal data completely private.

Real-World Use Cases for Selective Disclosure
Gaming Platforms
Many online games and gaming platforms have age restrictions for certain content or features.
Example: A gaming platform might require proof that you're over 18 to access mature-rated content. Using selective disclosure technology, you can generate a proof from your passport attestation that reveals only your age, without sharing your full name, address, or other details.
Social Media
Some social media platforms have age restrictions for certain features or content.
Example: A social platform might require age verification to access certain features or content. With selective disclosure, you can prove you're over 13 (or 16, or 18) without revealing your exact date of birth.
Financial Services
Some DeFi protocols and financial services have age restrictions for compliance reasons.
Example: A DeFi lending protocol might require proof that you're over 18 to access certain financial products. Selective disclosure technology allows you to provide age verification without sharing other personal information.
Content Platforms
Video streaming, adult content, and other platforms often require age verification.
Example: A content platform might require proof that you're over 18 to access certain content. Using privacy-preserving verification, you can verify your age without revealing your identity.

Technical Details: How Selective Disclosure Works
Understanding Selective Disclosure Technology
When you need to prove your age, Zipwire Attest generates a selective disclosure proof (also called a selective reveal proof, minimal disclosure proof, or privacy-preserving proof) that:
Reveals only your age - Shows the specific information needed through selective disclosure
Proves authenticity - Verifies the information comes from your attested document
Maintains privacy - Keeps all other document information hidden using minimal disclosure
Is verifiable - Can be checked by anyone using the ProofPack specification
Common Terms for Selective Disclosure Technology
This technology is known by several names in the industry:
Selective Disclosure - Disclosing only what's necessary
Selective Reveal - Revealing only specific information
Minimal Disclosure - Sharing the minimum information needed
Privacy-Preserving Verification - Verification that protects privacy
Attribute-Based Credentials - Credentials that reveal specific attributes only
Example Selective Disclosure Proof
Instead of sharing your full passport, you might generate a selective disclosure proof that reveals only:
"This person is over 18" (true/false)
"This person is over 21" (true/false)
"This person's age is between 25-35" (true/false)
Each of these is a selective disclosure that proves the specific fact without revealing your exact age or any other personal information.
