title: Can you hide data in text?
body: <p>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?</p>
  
  <p>Example: I have the following text:
  "The cat sat on the dog and was happy."</p>
  
  <p>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.</p>
