c't Content Shariff (Round 3)
Summary
Embedded Social Media Content with respect to privacy. c't Content Shariff is planned to be released as open source. It's the brother of our very popular c't Shariff (https://github.com/heiseonline/shariff).
The solution
Facebook, Google+ and Twitter supply official sharing code snippets which quietly siphon personal data from all page visitors. If a media outlet embeds a tweet, a Facebook post or other social media content in their website, it exposes visitor data to the social media sites that can track the user behaviour. c't Content Shariff gives the user the choice: It makes the embedded content visible via a proxy that doesn't directly expose the user's data.
