Hi Product Hunt community! 👋 I’m Dries, the creator of Authenti. With the rapid rise of AI image generators, deepfakes, and Photoshop, it's becoming almost impossible to know if a photo is authentic. This causes major headaches in real estate inspections, insurance claims, construction handovers, and legal evidence. I built Authenti to bring absolute trust back to photos — completely offline. The moment you take a photo in Authenti, your iPhone's physical Apple Secure Enclave security chip cryptographically signs the image (P-256 ECDSA), binding the UTC timestamp, GPS coordinates, and device ID directly into the EXIF metadata. Why Authenti is built differently: 🔒 100% Offline & Serverless: Zero cloud storage, zero tracking, zero accounts. 🛡️ Hardware-Backed: Protected by Apple's Secure Enclave chip. 🟢 Instant Verification: Import any photo to check for tampering. 📄 A4 Audit Reports: Export official PDF certificates for legal dossiers. I’d love for you to try it out and let me know your thoughts! I'm here to answer any questions. 🙌
