Steganography

Steganography is the technique of hiding secret data within an ordinary, non-secret, file or message in order to avoid detection. The use of steganography can be combined with encryption as an extra step for hiding or protecting data.

How it works

1. Hide a secret message inside an Image

• Open the image and look at its pixel in hexadecimal
• If the blue pixel's channel falls in the range of 0-5 then 1 bit of information is stored
• End the stream with a delimiter of 1111111111111110 to take up 2 bits

2. Extract embedded message from Image

• Pull all the blue bits of 0 and 1s until the stream obtains the delimiter of 1111111111111110

Quickstart

2. Starting the Server
