A cool application to hide and extract images and text into another image without any noticeable distortion.
This application is based on the algorithm in a [paper] (http://www.jait.us/uploadfile/2016/0204/20160204115435816.pdf) I published as first author, with slight modifications.
###what's it all about
It's all about security. If you want to send images and/or text secretly via the web, this is the way to go.
You might be wondering "How secure can it be after you share it?" You can see I am in a hard position, here - if this project becomes that popular, is it a success or failure? lol
###how to install
