BlnBDI informs Senate administrations about the use of Facebook pages
Facebook pages must be switched off if the operators cannot prove their compliance with data protection law. This is the result of a new report by the Data Protection Conference, about which the Berlin Commissioner for Data Protection and Freedom of Information (BlnBDI) informs the Senate administrations.
Volker Brozio, acting head of the BlnBDI department: “Facebook pages cannot currently be operated in compliance with data protection regulations. This is the conclusion reached by European and German courts as well as a new report by the German data protection authorities. The Senate administrations should deactivate their Facebook pages if they cannot ensure compliance with data protection law. As public authorities, they have a special responsibility and a role model function.”
