  The ever increasing popularity of Facebook and other Online Social Networks
has left a wealth of personal and private data on the web, aggregated and
readily accessible for broad and automatic retrieval. Protection from both
undesired recipients as well as harvesting through crawlers is implemented by
simple access control at the provider, configured by manual authorization
through the publishing user. Several studies demonstrate that standard settings
directly cause an unnoticed over-sharing and that the users have trouble
understanding and configuring adequate settings. Using the three simple
principles of color coding, ease of access, and application of common
practices, we developed a new privacy interface that increases the usability
significantly. The results of our user study underlines the extent of the
initial problem and documents that our interface enables faster, more precise
authorisation and leads to increased intelligibility.
