Press freedom & sources
Journalists and their sources exchange material under surveillance without leaving a detectable trail.
Steganography · invisible by design
Hide data where no sensor can see it.
Sensor-Proof weaves your information invisibly into ordinary files — images, audio, documents. No signature to detect. No metadata to trace. Encryption hides what your data says; steganography hides that it exists at all.

How it works
Conceal — don't just encrypt.
Encryption turns your message into obvious gibberish: anyone watching the wire knows a secret is there, even if they can't read it. Steganography removes that signal entirely.
-
01
Embed
Your (already-encrypted) data is spread across the least-significant bits of an ordinary carrier — a photo, a song, a PDF.
-
02
Conceal
The carrier looks, plays, and measures identically to the original. There's no anomalous pattern for a scanner or sensor to flag.
-
03
Recover
Only the holder of the key knows data is present — and can extract it. To everyone else, it's just a file.
Live demo
Hide a message in plain sight.
Type something secret, weave it into the image, then try to find it. Everything runs locally in your browser — nothing leaves this page.
Ready — type a message and hit “Hide in image”.
Spot the difference? Neither can a sensor. The change lives in bits too faint for any eye or detector — until someone with the key looks. No signature. No trace.
Built for good
Where untraceable matters.
Steganography protects people and information that can't afford to be flagged in the first place.
Human-rights & aid work
Activists and field staff in hostile networks keep people safe by hiding that a message ever existed.
Invisible watermarking
Embed ownership and licensing marks inside media — provable, but invisible and hard to strip.
Tamper-evidence
Hide a fragile checksum so any later edit to a file becomes detectable to the rightful holder.
Confidential business data
Move trade secrets and deal documents without advertising — to any monitor — that something sensitive is in transit.
Resilient key backup
Stash recovery phrases and key shards inside everyday files instead of an obvious, targetable vault.
Untraceable by design
Nothing to detect. Nothing to trace.
No signature
The carrier's statistics stay normal, so signature- and anomaly-based sensors have nothing to alert on.
No metadata trail
No special file type, header, or extension announces that a payload is present.
Defense in depth
Encrypt first, conceal second. Even in the unlikely event data is found, it's still ciphertext.
Your keys, your data
Hide and recover client-side. The payload never has to touch a server you don't control.
Built for privacy, security, and legitimate protection — journalism, human rights, and enterprise confidentiality.
