Use of social plugin

This website uses the social media plugin Shariff.

Shariff allows you to use social media without unnecessarily compromising your privacy. The c’t project Shariff replaces the usual share buttons of social networks and protects your surfing behavior from prying eyes. Nevertheless, a single click on the button is enough to share information with others. You don’t need to do anything else for this – the webmaster has already taken care of everything.

The usual social media buttons transfer the user data to Facebook & Co. with every page view and give the social networks precise information about your surfing behavior (user tracking). To do this, you do not need to be logged in or a member of the network. In contrast, a Shariff button establishes direct contact between social network and visitor only when the latter actively clicks on the Share button.

In this way, Shariff prevents you from leaving a digital trail on every page you visit and improves data protection. Then you can like, +1 or tweet as you see fit – the social network does not receive any more information.

Thanks to Shariff, the display of „likes“ comes from the operator of the page with the buttons. Because Shariff is integrated by the webmaster, you as a visitor do not have to do anything else.The widespread share buttons pose a significant data protection problem because they make unnoticed contact with the servers of the social networks. Facebook, for example, sends the number of „likes“ directly to the visitor’s browser – and logs individual surfing behavior in the process.

Shariff acts as an intermediate instance here: Instead of the browser, the website operator’s server queries the number of likes – and only once a minute, to keep traffic within limits. The visitor remains anonymous.

More information about Shariff can be found in the article Protect and share, which is completely online; there is also the topic forum c’t Shariff – 1 click for more data protection for discussions.
