How it works

The steganography is technology to hide secret message into image data.
This steganography module can embed bytes params into image data.
Sample is following.

[Original Image]

[Embeded Image]

Original image is not embeded anything and embeded image is embeded 680 characters. This module algorithm allows you to embed secret message with slightly difference change. 1 pixed is 3 bytes and 3 bytes are 2^24 bit. With this algorithm, it changes just 2 bit of 2^24 bit(4 bit / 16777216 bit) for each pixel when this module embeds params into image. If you can see the difference, you can be a space telescope👍

Hubble space telescope has 600 eyesigth.
