protect

your

identity Fingertrap 2 is a free toolkit designed to help

whistleblowers identify digital fingerprinting

in text documents.

The Danger Imagine you're an employee at the Washington Township Nuclear facility in Bergen County, NJ. You've discovered a conspiracy to cover up a secret project, and plan to leak the evidence to the Nuclear Regulatory Commission. Your manager has sent you an email which you intend to include in the leak, but could it reveal your identity? Copy the email below, and paste it into the form to see if it contains hidden fingerprinting. Reminder ‌﻿​﻿‌﻿‌﻿‌﻿​﻿‌﻿​﻿‍﻿‌﻿​﻿​﻿‌﻿​﻿​﻿‌﻿​﻿‍﻿‌﻿​﻿​﻿​﻿‌﻿‌﻿‌﻿‌﻿‍﻿‌﻿​﻿​﻿‌﻿​﻿​﻿‌﻿‌﻿‍﻿‌﻿​﻿​﻿‌﻿​﻿​﻿​﻿​﻿‍﻿‌﻿​﻿​﻿​﻿​﻿‌﻿‌﻿​﻿‍﻿‌﻿​﻿​﻿‌﻿‌﻿​﻿‌﻿​﻿‍﻿‌﻿​﻿​﻿‌﻿‌﻿​﻿‌﻿​﻿‍﻿‌﻿‌﻿​﻿‌﻿‌﻿‌﻿‌﻿‌﻿‍﻿‌﻿‌﻿​﻿​﻿​﻿‌﻿‌﻿‌﻿‍﻿‌﻿‌﻿​﻿​﻿‌﻿‌﻿​﻿‌﻿‍﻿‌﻿‌﻿​﻿​﻿‌﻿‌﻿​﻿‌﻿‍﻿‌﻿‌﻿​﻿​﻿‌﻿​﻿​﻿​﻿‍﻿‌﻿‌﻿​﻿​﻿‌﻿‌﻿​﻿​to all employees, sub-level 6 is a restricted area. If you attempt to access that level, it will be considered a violation of your employment contract, and you will be terminated immediately. Uh-oh. The email contains zero-width hidden content: If you had leaked this email, and it were digitally published, your identity would be revealed to your employer. Game over.

The Solution Paste the example email into the form below, and non-standard characters will be flagged. International Support: Chinese, English, Korean, Russian, and Devanagari.

What The FAQ Who created this project, and why should I trust you? Nefarious Laboratories is a data privacy firm in NYC. We design free security solutions because we believe in supporting the greater good. Every line of our open source code is written by hand. Could someone defeat this solution? Fingertrap uses a "default deny" posture by matching all input against a predefined character set. If the input doesn't match the character set, it gets flagged. We consider this a reasonably future-proof solution.
