Verfahren zur Anonymisierung von Verbindungsdaten in IP-Paketen und Vorrichtung zur Durchführung des Verfahrens

The invention relates to a method for anonymizing connection data in packet-based communication connections in networks of all types, and said method can be used for anonymizing any connection data, such as IP packet data, aggregated packet data, telephone connections, Web service use, Web service access, email, chat protocol, and short messages for example. Before said connection data or data derived therefrom can be made available, features in the data packet must be anonymized, said features enabling assigning data to a person unambiguously. In this context, the usability of data for the intended purpose must not be impaired or must only be negligibly impaired.; When identifying features are replaced with a pseudonym, it is possible to bypass or cancel the anonymizing in IP and connection data by establishing a relations profile and with only a relatively small amount of previous knowledge about the communication partner.
