§ 2 HDSIG
Definitions
(1)Public bodies are the authorities, the organs of the administration of justice and other institutions organised under public law of the Land, the municipalities and counties or other legal persons under public law subject to their supervision, as well as their associations regardless of their legal form. Where a non-public body performs sovereign tasks of public administration, it shall be a public body within the meaning of this Act to that extent.
(2)Public bodies shall be treated as non-public bodies insofar as they participate in competition as public-law enterprises. To that extent, the provisions of the Bundesdatenschutzgesetz applicable to non-public bodies and §§ 5 to 18 and 23 shall apply.
(3)Associations under private law of public bodies that perform tasks of public administration shall be considered public bodies regardless of the participation of non-public bodies, if one or more public bodies hold the absolute majority of shares or are entitled to the majority of votes. Where an association under private law that is considered a public body under sentence 1 participates in another association under private law, sentence 1 and para. 2 shall apply mutatis mutandis.
(4)Anonymous information is information that does not relate to an identified or identifiable natural person. Personal data that have been anonymised in such a manner that the data subject can no longer be identified are anonymised data. A natural person is identifiable if she or he can be identified, directly or indirectly, taking into account all the means reasonably likely to be used by the controller or by another person to establish the identity of the natural person. In determining whether means are reasonably likely to be used to identify the natural person, all objective factors, in particular the costs of identification and the time required therefor, should be taken into account, having regard to the technology available at the time of the processing and technological developments. zur Einzelansicht § 2 Zweiter Abschnitt Rechtsgrundlagen für die Verarbeitung personenbezogener Daten
