Store description excerpt
"I was there, at that exact moment, and I captured this." ―― Can you prove your media is 100% genuine? In an era of deepfakes and AI-generated media, altering photos, videos, and audio has become effortless. The real threat today is not just spotting the fakes, but the sky-high cost of proving what is actually REAL. ProofShot is a next-generation digital evidence camera and recorder designed to minimize the cost of proving the truth. ■ Maximizing the "Cost of Tampering" with a Robust Logic ProofShot doesn't rely on unproven, complex technologies. Instead, it binds established, trusted data points—GPS coordinates, device motion (3-axis acceleration/tilt), and cryptographic hashing (SHA-256)—into an inseparable context. To forge data recorded by ProofShot, one would have to falsify not just a file's metadata, but simulate a physically consistent GPS path and match the physical gravity/tilt sensors of the device in millisecond synchronization—all while keeping the SHA-256 hash valid. By raising the technical and time cost of tampering to an astronomical level, we make data alteration virtually impossible, guaranteeing the authenticity of your facts. -------------------------------------------------- ◆ Why ProofShot is Your Ultimate Shield -------------------------------------------------- ■ Photo, Video, and Audio Verification Secure not just static photos, but "videos" for dynamic scenes and "audio recordings" for conversations or harassment claims. All media files are safely packaged with context. ■ Continuous GPS & Physical Sensor Binding ProofShot captures more than a single snapshot of location. It continuously logs your path and physical device movement around the moment of capture. This "continuity of action" aligns with physical laws, completely neutralizing single-point mock location spoofing. ■ Tamper-Proof Cryptographic Signature (SHA-256) Synchronized with the file system I/O, a SHA-256 cryptographic hash is generated in milliseconds. The media, GPS log, and sensor data are instantly locked. We mathematically guarantee that the file has not been altered by even a single bit since the moment of recording. ■ Absolute Privacy: 100% On-Device ProofShot prioritizes your privacy. Your recorded media, locations, and sensor logs are NEVER sent to any external servers. Everything is processed and stored locally on your device, ensuring maximum security for sensitive personal or corporate data. -------------------------------------------------- ◆ Ideal for Personal Defense and Business Verification -------------------------------------------------- - Securing evidence for workplace harassment or disputes. - Recording vehicle accidents or property damage (with precise physical device tilt). - Tenant move-in/move-out checks to avoid unfair security deposit deductions. - Fieldwork, inspection, and professional delivery verification ("Proof of Presence"). -------------------------------------------------- ◆ Key Features -----------------
