I wish to put some text on a page and hide some data in that text. Does anybody know of any methods / patterns that have been used in the past to solve this problem?
Example: I have the following text: ‘The cat sat on the dog and was happy.’
I also have the number 123. I want to hide this number in that sentence such that the sentence can be placed on a web page and only someone in the know would be able to find the data.
HTML makes it quite easy to do this, actually. No need for really cunning amounts of steganography, etc. Let’s see:
This sentence embeds 123 and then stops embedding.
This sentence embeds 0102 and then stops embedding.
(We’ll have to see whether it actually works in markdown, but I suspect so.) Admittedly it’s pretty obvious if you know that there’s something to look for, but I think you’ll agree it’s not obvious to casual observers.
I’ve left it as a little puzzle to work out the scheme, but add a comment if you want it to be explicitly explained.
