The Secure Camera System is a cryptographically verifiable recording platform that hashes raw sensor data for every frame before any compression or disk storage occurs, creating an immutable chain of frame hashes where each frame is linked to the previous one. These frame hashes are organized into Merkle trees, and the resulting Merkle roots are digitally signed by a hardware-protected device key and periodically anchored to the Bitcoin blockchain to provide an independent public timestamp. The system features a simple interface with a Record button that captures video and generates cryptographic proof data, and a Verify button that recomputes every frame hash, rebuilds the Merkle trees, validates digital signatures, and confirms blockchain anchors to detect any modification, insertion, deletion, or corruption of footage. Additional metadata such as GPS time, IMU data, environmental measurements, and sensor fingerprints can be incorporated into the signed records, creating a tamper-evident evidence chain that allows any third party to independently verify the authenticity, integrity, and existence of the recording without relying on trust in the camera manufacturer or software provider.
