Signed Photo Emailing Tool

iOS camera that cryptographically proves your photos are real and unmodified.

Signed Photo Emailing Tool is an iOS camera app that signs every photo with a C2PA content credential at the moment of capture, proving the image is real, unmodified, and taken by a camera. You own your photos completely. No blockchain. No accounts. No one else's servers. C2PA (Coalition for Content Provenance and Authenticity) is the open standard backed by Adobe, Microsoft, Google, and the BBC for verifying digital media. Until now it has only been available in professional desktop tools. Photo Emailing Tool brings it to your iPhone camera, automatically, every time you take a photo. The credential is embedded invisibly inside the JPEG itself. If anyone edits the photo, even a single pixel, the credential breaks and the tampering is detectable. Recipients can verify any photo at verify.contentauthenticity.org in seconds. The app was built for workflows that require photographic evidence- field inspections, insurance claims, legal documentation, support tickets, property management, and anywhere a photo needs to be trusted. Set your destination email once, take your photos, and send. Everything goes through your own iOS Mail app. Nothing touches our servers. Features: • Every photo signed with a C2PA content credential at capture • Tamper detection: any modification to the image breaks the credential • Verify any photo at verify.contentauthenticity.org • You own your photos- no accounts, no cloud, no third-party servers Persistent email address — enter once, never again • Custom subject line number for batch and ticket reference • Batch photo capture and sending in a single session • Auto-saves every photo to your Camera Roll • Sends through your own iOS Mail app
