Authonex vs Zyphe Age Verification

Authonex is an identity verification platform available through the web, an API, or self-hosting. It scans identity documents, screens watch lists, compares faces with ID photos, and issues digital IDs. Document checks cover format, barcode integrity, security features, expiry, revocation, field consistency, and fraud indicators. Digital IDs are cryptographically signed and can be shown as QR codes that refresh every 60 seconds. Zero-knowledge proofs can confirm claims such as age without exposing the underlying personal data. Risk tools include behavioral analysis, device fingerprinting, threat intelligence, real-time scoring, custom rules, and blocklists. The security page describes AES-256 encryption at rest, TLS 1.3 in transit, and hybrid Ed25519 and Falcon-512 signatures. Authonex states it is SOC 2 Type II and ISO 27001 certified and GDPR compliant. Its open-source software is available under the MIT license for customer servers. Cloud verification costs $0.05, paid once. The free allowance is unclear: the homepage lists 100 verifications per month, while developer documentation lists 1,000.

Zyphe Age Verification checks whether a user meets the minimum age configured for access to restricted products, services, or content. Rules can be set per verification flow and adjusted for a market, such as an 18- or 21-year threshold. The service checks government identity documents covering more than 4,000 document versions from 213 countries and territories. Checks include active liveness, anti-spoof measures, and injection-attack detection. After an initial verification, a user can present a KYC Passport zero-knowledge proof of being over the threshold without revealing a birth date or document. A location step compares GPS with the IP country and flags VPN or proxy use and blacklisted IPs. Zyphe says documents are processed transiently and stored encrypted in the user's vault; it retains the result, audit log, and cryptographic proof. Integration options include APIs, browser and Node.js SDKs, hosted verification links, iframe embedding, and mobile WebView. Business is listed at free, with a monthly KYC allowance; checks above the allowance and add-ons are charged per check. Zyphe says it does not offer facial age estimation.
