I'm 18 and Built an Open-Source Camera That Cryptographically Proves Photos Are Real

In 2026, generating a photorealistic fake image takes seconds. The C2PA standard (Adobe, Microsoft, Google) solves this with Content Credentials — but only on Samsung S25+ and Pixel 10. The other 3 billion Android phones have nothing. I'm 18, from Brazil, and I built TrueShot to change that. What happens when you take a photo 14 physical sensors are sampled at the exact instant of the shutter — accelerometer, gyroscope, magnetometer, barometer, light, proximity, gravity, rotation vectors, and more SHA-256 hash is computed on the JPEG bytes up to the EOI marker ECDSA P-256 signs the manifest via hardware-backed Android Keystore (StrongBox preferred, TEE fallback) The signed manifest is appended after the JPEG EOI marker — standard image viewers ignore post-EOI data, so the photo displays normally everywhere Change one pixel → hash breaks. Forge the signature → mathematically impossible without the device's hardware key. Anyone can verify in a browser at true-shot.vercel.app/verify. The
