legal issues


Mit geringem technischen Aufwand können AIS-Daten empfangen und aufbereitet werden. Diese enthalten mindestens eine Individualnummer (MMSI), Zeitstempel und Position des Schiffes und sind u.U. als 'personenbezogene Daten' anzusehen. 

Die AIS-Informationen stehen 



  • anderen Schiffen (Kollisionsverhütung, Erleichterung des Verkehrs)
    • 

  • Behörden (Verkehrslenkung und Überwachung)
    • 

  • Dritten (über Portale wie marinetraffic , vesseltracker, fleetmon)


zur Verfügung.

Mindesten zwei Länder sehen die Zurverfügungstellung der von ihnen empfangenen Daten als legitim an:
