Even when we think we’re communicating in private, whether by email, text messages, private messages on social media etc, the fact is that a bunch of 3rd parties, like tech companies, governments, ISPs and advertisers, all see that data too. And it’s not just that they can see it, they’re actively collecting and analyzing all of it.
One of the downsides of encrypting messages and emails to combat this, is that since so few people are doing that, you will stick out like a sore thumb to anyone who is monitoring the data, and probably will receive closer scrutiny. For example, it’d be pretty easy to filter out all messages that contain PGP headers.
What if we could still encrypt the data, but make it look like ordinary plain text, made up of dictionary words? If it was done in a dynamic way, so it was different for every person, it would be hard to detect using passive data mining techniques. That would allow us to use existing services like gmail, twitter, facebook, reddit etc on the clearnet, while still protecting our message content.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Great! Preparing the resistance… Did you talk about politics with bunnie? Would love more converage on the ‘right to repair’ and ‘right to tinker’… will it someday be illegal to own an iphone that is NOT reporting our position and discussion? For tax breaks, Apple will do anything. Will it be illegal to broadcast video streams of police abuse at NoDAPL?
Steganography is another method, good for longer messages. After encrypting, each bit of the message is “hidden” in the Least Significant Bit (LSB) of an image.
GIF and PNG work better than JPG.
You get one bit for each color R, G, B so 8 pixels save 3 bytes of data. An 800 x 600 image can conceal 18,000 bytes.
