How to Hide Online is now available for the iPad. A version for Android tablets is coming soon.



The book explores the secrets of how to hide information where it can't be seen. The five core chapters describe five different techniques for slipping information into the virtual cracks of larger files:

  • Digital Photos can carry secret messages embedded in the tiny spots of red, blue and green.
  • Sports game transcripts can hide extra words between the virtual lines.
  • Secret Texts can be split into many parts like a puzzle so that you need all of them before the secret message can be read.
  • Mistyped words could just be a mistake -- or they could hold an elaborate secret.
  • Shopping lists can carry another message in the order of the items.



Each chapter comes with a working illustration where you can try all of the ideas.
