Authentk
Verify real people with cryptographically signed, time-stamped selfies
Authentk lets you prove a photo is genuinely you, taken now, and unedited. The app signs selfies with a real-time cryptographic challenge and embeds a watermark, timestamp, and a scannable verification code so anyone can confirm authenticity without installing an app. Use it before marketplace meetups, dates, roommate searches, or freelance gigs to reduce fraud and build trust. Platforms can integrate Authentk to request live verifications from users and keep a shareable record.
