ProofLens-Gerichtsfeste Fotos
Fälschungssichere Kamera
Prooflens ist eine forensische Kamera, die jedes Foto beweisbar macht. Auslösen genügt – im Moment der Aufnahme wird ein fälschungssicherer Nachweis eingebrannt: gerichtsfeste Beweise mit einem Tipp.
Jedes Foto, nachweislich deins. Bei jeder Aufnahme wird ein kryptografischer Nachweis eingebrannt – nur der Hash verlässt dein Gerät.
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.
