Like and Share buttons
The Like and Share buttons are widespread on social networks such as Facebook, Twitter, Google+, etc. However, the way they operate is as follows: without any active clicks by the user, data is transmitted to the operator of the network platform simply by loading the page. In addition to the URL of the loaded page, this data contains an identifier that runs in the background and directly connects to the user account of the registered user. Facebook, Twitter, etc. use this to create surfing profiles of their users. This does not meet the data protection and privacy requirements of the University Hospital Zurich (UHZ).
Deactivated buttons are therefore installed on these websites to disable contact with the servers of social networks. Only once users activate them by consenting to communicate with Facebook, Twitter, Google+, etc. do the buttons become active and establish a connection. Users can then submit a recommendation with a second click. If a user is already registered with a social network, this is carried out automatically for Facebook and Google+ without opening a further window. For Twitter, a pop-up window appears that allows you to edit your tweet.
Clicking one of these buttons means that the user agrees to forward data to the respective social network operator, but only for this page and for the selected service. The deactivated button will appear again when you access another UHZ page. This means that you can use the social networks without enabling them to create complete surf profiles.
