Prove your photos are real. PixelAuth embeds an invisible watermark and generates a tamper-proof RFC 3161 certificate — entirely on your device. In an era of deepfakes and AI-generated images, proving that your photo is real has never been more important. PixelAuth gives you the tools to authenticate your media — invisibly, verifiably, and entirely on your device. HOW IT WORKS Sign any photo or image with an invisible DCT watermark — imperceptible to the human eye, yet detectable by PixelAuth at any time. Capture directly from your camera with your signature embedded at the moment of shooting. Every signature is paired with an RFC 3161 cryptographic timestamp from a Time Stamping Authority of your choice. Your media gets a tamper-proof PDF certificate including a QR code for instant verification — shareable as digital proof of authenticity. KEY FEATURES • Invisible DCT watermark — no visible alteration to your image • RFC 3161 timestamp — open standard, internationally recognized • PDF certificate with QR code — verifiable by anyone, anywhere • On-device processing — your photos never leave your device • 3 protection modes — Discreet, Balanced, Robust • eIDAS-compatible — works with qualified TSA providers for legal value in the EU • Signed Capture — sign photos at the moment you take them • Scan & verify — detect the watermark in any previously signed image PRIVACY FIRST PixelAuth processes everything locally.
