ProofLens-法廷レベルの電子証拠
改ざん検知カメラ
Prooflens は、すべての写真を証明可能にするフォレンジック級カメラです。シャッターを切った瞬間に改ざん検知の証拠が写真へ焼き込まれ——ワンタップで法廷レベルの証拠になります。
すべての写真を、証明できる自分のものに。シャッターの瞬間に暗号証明を埋め込み——端末から出るのはハッシュだけ、写真は外に出ません。
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.
