★ 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.

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. You can find a good introductory guide to these topics at https://securityinabox.org

Modern encryption is based on digital “keys”. OpenKeychain stores and manages your keys, and those of the people you communicate with, on your Android.

Spidertxt allows you to connect your Android wirelessly to Spidertxt capable Spiders via a Bluetooth connection. Spiders are spidertracks real time GPS tracking units.
Once connected to the Spider in your aircraft, you are able to send and receive SmS text messages to and from any mobile phone on the ground, or from the spidertracks website.
Spidertxt messages are just like normal text messages, but they are routed through your Spider to the Iridium Satellite Network, which means there are no blackspots or loss of coverage anywhere you fly.
Sending a Spidertxt message through your Spider to a mobile phone is $1.00 (USD). Replying to a Spidertxt message is $0.50 (USD) plus any local SMS charges you may incur.
