ProofLens-법적 효력 전자증거
변조 방지 카메라·블록체인 증명
Prooflens는 모든 사진을 증명 가능하게 만드는 포렌식급 카메라입니다. 촬영하는 순간 변조 방지 증명이 사진에 새겨집니다——한 번의 탭으로 법정에 제출할 수 있는 증거가 됩니다.
모든 사진이 내 것임을 증명——셔터를 누르는 순간 암호화 증명이 새겨집니다. 휴대폰을 떠나는 건 해시뿐, 사진은 절대 전송되지 않습니다.
Core Features
Cryptographic Proof
At capture, each photo is hashed with SHA-256 and stamped by an RFC 3161 authority — proving it existed at a point in time and hasn't been altered since.
Blockchain Anchoring
Optionally anchor the hash to the Bitcoin blockchain via OpenTimestamps for permanent, independent, trust-minimized verifiability.
Forensic Watermark
Burn time, GPS coordinates, altitude, and custom notes directly into the photo — watermark template and fields fully configurable.
Local-First Privacy
Photos are captured, watermarked, and hashed on-device and never uploaded — no account, no tracking. Optionally strip the device serial for anonymous evidence.

FAQ
Does Prooflens upload my photos?
No. Photos are captured, watermarked, and hashed locally on your device. To create a timestamp, Prooflens transmits only the photo's SHA-256 hash — a one-way fingerprint from which the original image cannot be reconstructed.
Can the timestamp be used as legal evidence?
Prooflens provides a cryptographic proof of existence — that a photo existed at a given time and hasn't been altered. It is technical evidence, not legal advice; whether it's admitted depends on the evidentiary rules of each jurisdiction.
Does it need an internet connection?
Capture, watermarking, and hashing work fully offline. Obtaining an RFC 3161 timestamp and blockchain anchoring require a connection; when offline, proofs queue locally and complete automatically once you're back online.
Is blockchain anchoring free?
OpenTimestamps is a free, open protocol. Many proofs are aggregated into a single Bitcoin transaction, so anchoring carries no per-proof cost to you.
