PixelKnot: Hidden Messages Description
Have a secret that you want to share? Why not hide it in a picture? With PixelKnot, only your friends with the secret password can unlock your special message. Everyone else just sees a pretty picture. It’s a fun and easy way to share hidden messages without anyone knowing. Take those pixels, twist them in a knot, and see for yourself!★ DISGUISE YOUR MESSAGES: Pictures are public, the text is hidden inside. Even a trained eye will think the image is unedited. It’s security through obscurity!
★ FOR YOUR EYES ONLY: Put a password on the secret message to make sure that no one can read it except the person it’s meant for.
★ EASY IMAGE CHOOSER: You can use the camera to take photos, or just use photos you’ve already taken.
★ INVISIBLE CHANGES: Even a trained analyst analyst shouldn’t be able to detect any message. The image bytes should seem undistorted.
★ SHARE ACROSS PLATFORMS: Want to share the images over email, file sharing tools (like Dropbox & Sparkleshare), social media (like Google+ & Flickr) or directly through Bluetooth or NFC? Not a problem! The messages are still recoverable on the other side. We'll have even more tools (like Facebook) working soon, so stay tuned!
★ AD-FREE: We want your love, not your money.
★ MATHEMATICALLY SECURE: We use the newly developed steganography algorithm F5 which implements matrix encoding to improve the efficiency of embedding and employs permutative straddling to uniformly spread out the changes over the whole steganogram.
★ ATTACK RESISTANT: We’ve launched attacks on images with messages hidden in them using a specialized version of stegdetect, an automated tool for detecting steganographic content in images. In most cases, the pictures have been impervious to attack. We will be including detection in an upcoming version of the application so you can easily test it yourself!
★ ARTIST FRIENDLY: The app features the work of Pablo Picasso. His painting "Girl before a Mirror" from March 1932, to be exact. We hope it inspires you to share beautiful imagery and wonderful ideas.
★ WE SPEAK YOUR LANGUAGE: PixelKnot is available for friends who speak: German (Deutsch), Greek (Ελληνικά), Spanish (Español), and Vietnamese (Tiếng Việt).

***Disclaimer***
The Guardian Project makes apps that are designed to protect your security and anonymity. The protocols that we use are widely regarded as the state of the art in security technology. While we are constantly upgrading our software to combat the latest threats and eliminate bugs, no technology is 100% foolproof. For maximum security and anonymity users must utilize best practices to keep themselves safe. PixelKnot is still an experimental application and should not be used in real world deployments.

<span style="color:red">Uri Blumenthal:</span> It works - tested between two different hardware platforms running different versions of Android. Open source, algorithm described. Registers itself as image producer/consumer, do can export and import images directly from other apps. One can port to other platforms for a cross-platform Stego app. Bad: unable to load an image to decode the message - have to go through another app. Very slow (perhaps inevitable with the algorithms used). Somewhat unstable - it didn't work for me (refused to decode), now somehow it does, unsure if it's a streak of luck to run out soon, or it will work on from now on.<br /><br /><span style="color:red">:</span> Very Impressed I have to say well done. Although I am ignorant of the technology your app deserves 5stars for the idea alone. My only suggestion perhaps a little more user friendliness with regards to not keeping the encrypted images in a separate labeled folder and maybe some way of making app invisible. I'm really very impressed.<br /><br /><span style="color:red">Tisha Beedle:</span> Great App/Responsive Developer I find this app very useful. I wanted a way to watermark my art invisibly. This is wonderful! At first, I had an issue trying to decrypt the messages. I emailed the development and actually got a response in a timely manner! These folks obviously care about the apps they provide. I want to say thank you and great job!! I have a request for development. Will you work on an app that fights against Stingray devices? Those devices are too creepy!!<br /><br /><span style="color:red">Miro Avramoff:</span> Brilliant! Just BRILLIANT!!! If you just think, how many codes and passwords a serious Internet Businessman - a Marketer, a Salesman, an Entrepreneur, a Developer or a coder - needs to lock somewhere written and hidden, maybe in an old book from the childhood, but what about fires, or earthquakes, that may physically damage the passes and codes? A #Yubikey could burn too :) And what about if you're a Political Activist and these codes don't save your money, but your life?!! I think the idea is underestimated by the voters here!...<br /><br /><span style="color:red">Shawn Cald:</span> The Guardian project Everything they deliver is genius we need more free thinkers like these guys who understand our freedoms and delivers the tools we need for our freedoms because the government won't give them to us they only take them middle finger up to corruption<br /><br /><span style="color:red">Marco Travolta:</span> I reinstalled more times and always the same problem: stopped to work. My phone is Uhappy Up 920 with android kitkat.<br /><br /><span style="color:red">Jamie Ogilvie:</span> Well done I could find no difference in images, this is gonna be stupid but in relatively new, how do you actually decrypt an image?<br /><br /><span style="color:red">Shawn Teasdale:</span> Fun little doodad, but... Can you decrypt without it making another copy? I always seem to end up with several copies of the same picture.<br /><br /><span style="color:red">Bill M:</span> Not bad Works fine but a little slow. It would be nice if it had a help file and the ability to hide a picture in a picture.<br /><br /><span style="color:red">Austin Wallace:</span> Crashes Seems like it would be a cool app but keeps crashing before I can try it.<br /><br /><span style="color:red">K WY:</span> Closes on decrypt EVERY TIME Not usable at all. Useless. Galaxy Note II<br /><br /><span style="color:red">American Ganja:</span> How do you use it? It would probably help if you tell people where to put the passcode to retrieve the message. What good is a password if there is nowhere to put it in.<br /><br /><span style="color:red">Mike Dooley:</span> WTF? Why don't you tell us that you decrypt by sharing the image to your app? Thank goodness professor google knew how to do it.<br /><br /><span style="color:red">YAzan M:</span> Great application This is a great application but it should have an option for decrypting files.<br /><br /><span style="color:red">:</span> Crap Shuts down after I choose photo from my library.<br /><br /><span style="color:red">Dannie Gregorio:</span> Seems great idea I wanted to test this and i have put the message in the picture, now how can i read it?<br /><br /><span style="color:red">Stephen Frick:</span> Picture secrets Secrets shared in the open. Very cool 😎<br /><br /><span style="color:red">Barbara Yodice:</span> Doesn't work. Forces closed Nothing to describe. It doesn't work at all.<br /><br /><span style="color:red">Ahmad Abo aljod Barsa:</span> Crash while setting a secure phrase<br /><br /><span style="color:red">Armin Rahmani:</span> It doesn't work... Or i can't...<br /><br /><span style="color:red">justin nobles:</span> Works, but..... ...... it took several minutes to put one word in a 3 Meg pic.<br /><br /><span style="color:red">Mick Zeller:</span> Very cool!<br /><br /><span style="color:red">Jacob Lynch August:</span> Excellent method to watermark images<br /><br /><span style="color:red">Brandon Murphy:</span> Doesn't work<br /><br /><span style="color:red">:</span> How to decode message<br /><br /><span style="color:red">Anthony M:</span> Perfect App This is an excellent easy to use app by the guardian project. After encoding image simply share the image via email or another protocol. Then to decode simply open your email client for ex. and download then open attachment with pixel knot to decode. Simple, Powerful!<br /><br /><span style="color:red">John Smith:</span> Very Disappointing Decryption has not worked one time yet; I always get a bad password message when I know better. Update: the password test worked one time and then not again. Not reliable. Hoped to recommend this like I have all your other apps...<br /><br /><span style="color:red">n feehan:</span> Best of its kind This app works perfectly if you know how to use it. However, it is very much in need of some ux - the interface is pretty frustrating and little guidance is given to the user. Five stars, though, because it is the best app of its kind by a large margin.<br /><br /><span style="color:red">Charles Elliot:</span> Has Potential, but currently is broken I hope this app is improved. As for now it's broken. It won't accept correct password for photos. It worked when I first installed it though, which is baffling. Right now I'm too afraid to use it. I would not store important information if I have a random chance of not getting it back. I'll keep it installed in the hope for an update.<br /><br /><span style="color:red">Homer Slated:</span> Perfect To those who can't seem to figure out how to decrypt files, try "open as..." then choose PixelKnot, which is registered as a mime type handler for images (doh!). Works for me, and no crashes. :-)<br /><br /><span style="color:red">Kandi Klover:</span> Good but no password Just swipe to the left instead of clicking the padlock. Passwords won't decrypt even when using the proper method. It has been over a year. Time for a fix plz<br /><br /><span style="color:red">BP Latimer:</span> Worked. Once. I managed to encrypt, email, and decrypt 1 image. Now, it looks like I can encrypt messages, but the app crashes immediately when I try to decrypt anything.<br /><br /><span style="color:red">Stephen Frame:</span> Its good but. It's too slow to be used often. The loading times take far too long.<br /><br /><span style="color:red">Alex Ian:</span> Not Quite Great idea, poor execution. Select pic, swipe left, enter text, padlock, enter pword, swipe left share. To open, navigate to image, Open With… but it won't accept pword. Frustrating.<br /><br /><span style="color:red">Scott Free:</span> really wanted this to work worked one time, now all it does is crash<br /><br /><span style="color:red">Anthony Pallone:</span> Works great, but.... One thing, if the image it is decoding does not have a hidden message it will freeze the app at a certain spot in the decoding process. Other than this, it is a great concept.<br /><br /><span style="color:red">Adamant Orcinus:</span> Bout time I have been sharing hidden files in public view for years. Mp3s as jpegs and soft ware as .gifs or png's. I'm glad to see others in the covert tip. Good job.<br /><br /><span style="color:red">Cody Smith:</span> Good, but needs some work A little slow. When I tried to open an unedited picture with this app it hung up searching for something, even though there was nothing there to find.<br /><br /><span style="color:red">Gerald McDowell:</span> Fantastic! This is one of the best apps I have ever tried. Great job!<br /><br /><span style="color:red">padraic stack:</span> How to decode? Great idea. Straightforward to encode a message in an image. Where is the option to decode the image? I couldn't find it.<br /><br />
