Social Steganography: A different way of privacy control

Thinking about who sees what, especially the part of your life that happens online, is hard work. You have to choose which people you want to know what about you. There are many ways. Danah Boyd has an interesting post on social steganography. Language (in a broad sense, not only words) is nothing without context. Actually, the meaning of language depends on the context. So the interpretation of your communication differs between groups. Maybe you'll recognize the situation that a colleague is telling something in a meeting and some people laugh, because they have a different context, and other people take it absolutely seriously. This is hiding a message in plain sight. Apparently people, especially teens, know they are being watched and try to change their communication in a way that it contains different messages for different (groups of) people. Quite interesting!

As the comments on Bruce Schneiers blog point out this isn't exactly new (first comment), but there's a science fiction novel on this subject. In this novel people changed their language to hide their real communication from an automated eaves dropping system.

The idea of social steganography became so appealing to me that I decided to create my first Android app with the sole purpose of allowing users to add hidden secret messages to seemingly normal Facebook status updates. It's called Securebook:
