Stealth Clipboard Steganography

Injects hidden, invisible zero-width characters into your clipboard text.

Stealth Clipboard allows you to hide private messages or unique codes inside standard text without changing its visual appearance. Using steganography principles and zero-width Unicode characters, this extension injects your secret data directly into your clipboard content. How to use: * Copy any normal text from a webpage or document. * Open the Stealth Clipboard extension. * Enter your secret code or tag in the input box. * Click "Inject". The extension adds the invisible code to the text currently in your clipboard. * Paste the text anywhere (emails, chats, docs). It will look identical to the original text. Verification: To check if a text contains a hidden message, simply copy that text and open the extension. It will automatically scan the clipboard and reveal any hidden "Stealth Clipboard" signatures. Features: * Seamless integration with the system clipboard. * Uses Zero-Width Space and Zero-Width Non-Joiner characters for invisibility. * Local processing: No data is sent to the cloud. * Instant verification and decoding of hidden payloads. 10 Creative Use Cases for Stealth Clipboard Beyond "signing" articles on Medium, here are 10 powerful ways to use invisible text injection: 1. The "Canary Trap" (Leak Detection) 🦜 If you need to send a sensitive memo to 5 different people but are worried one might leak it to the press or competitors, use the extension to inject a unique invisible name (e.g., "ID:John", "ID:Sarah") into each copy. If the text leaks, scan it with the extension to see exactly which version was shared. 2. "Dead Drop" Public Messaging 🕵️ Need to send a secure key or a private location to a colleague but only have a public Slack channel or Discord available? Post a mundane message like "Meeting notes are updated" but inject the sensitive data invisibly inside it. Only your colleague with the extension will know to look for it. 3. Contract & Legal Integrity ⚖️ When negotiating a text-based agreement via email or chat, inject a hash or timestamp into specific critical clauses. When the other party replies or sends the document back, you can verify that the text matches your original version exactly and hasn't been subtly altered. 4. Code Snippet Attribution 💻 Developers often share code snippets on StackOverflow or internal wikis. Inject your Author ID into the whitespace of the code. It won’t break the code (compilers usually ignore zero-width characters), but if someone copies your function into their project without credit, your signature remains embedded. 5. Invisible Watermarking for Designers/Copywriters 🎨 Before sending draft copy or slogans to a client for review, inject "DRAFT-UNPAID" into the text. If they use the text on their live website without paying, you can prove the text came from your specific draft document. 6. Customer Support QA Tags 🎧 Support agents can have standard reply templates with invisible "Agent IDs" injected. If a manager finds a support response pasted in a forum or a bad review, they can scan the text to see exactly which agent originally generated that response. 7. CTF Challenges & Scavenger Hunts 🚩 Great for gaming communities or cybersecurity training! Hide clues for the next stage of a puzzle inside a seemingly boring introduction paragraph on a wiki page. Participants must realize the text holds the key. 8. AI Training Data Markers 🤖 If you are publishing content and want to know if an AI model is scraping your specific data, inject a unique invisible UUID into your public posts. If that UUID shows up later in an AI's generated output, you have proof your data was ingested. 9. Social Media "Bot Trap" 🤖 Post a unique thought or joke on Twitter/X with an invisible signature. If a "repost bot" automatically scrapes and reposts your content, your invisible signature will likely be copied along with it, allowing you to prove you were the original source. 10. Digital "Invisible Ink" Love Notes 💌 Send a partner a standard grocery list or calendar invite, but hide a sweet, private message inside it. It’s a modern, digital take on the classic invisible ink used in handwritten letters.
