Proposed Idea for Steganography Assignment

The idea behind this technique is to utilize the presence of punctuation marks like , ; : “ etc. in the text for encoding a secret message. The secret message to be communicated will be hidden in any piece of text through binary encoding of punctuation marks. Two punctuation marks can be used to represent binary data or several punctuation marks can be used to represent binary combinations. The encoded message can then be embedded in an image file (BMP, GIF or grayscale) using any of the popular methods like LSB insertion etc. [1] An additional layer of secrecy can be added by first encrypting the message and then encoding it through the use of punctuation marks before embedding in the cover image file.
