Canary Token & Zero-Width Leak Catcher — Invisibly fingerprint confidential text & decode leaker fingerprints

Embed steganographic zero-width unicode characters into memos, code, and contracts to trace whistleblowers and unauthorized leaks in 1 click.

Step-by-Step Client-Side Workflow

  1. 1. Steganographic Watermark Generation: Encodes an employee name, leaker ID, or timestamp into a binary sequence of invisible zero-width unicode characters.
  2. 2. Transparent Injection: The invisible watermark is injected into confidential memos, emails, or code snippets without changing their visible appearance.
  3. 3. Forensic Audit & Decoding: Paste any leaked excerpt into the auditor to immediately decode the hidden leaker identity.

Frequently Asked Questions

What are zero-width characters and can the recipient see them?

Zero-width characters (such as Zero-Width Space \u200B and Zero-Width Non-Joiner \u200C) have no visual width or glyph. To the human eye and spellcheckers, the text appears completely unmodified.

Do zero-width watermarks survive OCR or screenshots?

No. Visual OCR or screenshots strip unicode bytes. Zero-width watermarking is designed for digital copy-paste leaks, emails, and text documents.
