+# BusySteg
+
+> Hide information content into busy areas of images, optimally
+
+## Basic Idea
+
+Some parts of the image (for example, tree foliage) are busier than
+others (for example, the sky). It is possible to hide upto even 4 bits
+per 8 bit pixel in such areas, with no perceptible change to the
+image. Additionally, such modifications are virtually impossible to
+detect using common steganalysis techniques.
+
+The original idea for this is taken from a paper
+titled ["Keyless dynamic optimal multi-bit image steganography using
+energetic pixels" by Goutam Paul et. al.](https://link.springer.com/article/10.1007/s11042-016-3319-0).
+
+The implemented technique is resistant against:
+
+1. Visual attacks
+2. Analysis though quality metrics
+3. Structural attacks
+4. Statistical attacks
+
+## Usage
+
+The code requires OpenCV 2.x, and CMake installed.
+
+Compile using:
+
+```
+mkdir bin
+cd bin
+cmake ..
+make
+```
+
+Hide data into an image using:
+
+```
+./busysteg <image path> <data file path>
+```
+
+Extract data from the image using:
+
+```
+./busysteg <image path>
+```
