These rules were specified in mid November by the Düsseldorfer Kreis in Wiesbaden, Germany.  The ‘Kreis’ is an association of all the top level data protection regulators in the non-legislative sector.

In the decision, the authorities specified that no faces, vehicle license plates or house numbers may be readily recognizable.  Further, affected property owners or residents must have the opportunity to object to the publication of the relevant images, both before and after their publication.  To enable these controls, the undertaking must inform the affected parties about their right to object.
