Abstract
(DE)
Verfahren zum Löschen eines Datenelements aus einer Datenstruktur, umfassend die folgenden Schritte: Berechnen eines Hashwertes mindestens auf Basis des zu löschenden Datenelements innerhalb einer Instanz, und Ersetzen des Datenelements in der Datenstruktur durch den berechneten Hashwert.
(EN)
The invention relates to a method for deleting a data element from a data structure, comprising the following steps: calculating a hash value at least on the basis of the data element to be deleted within an entity, and replacing the data element in the data structure by the calculated hash value.
(FR)
L'invention concerne un procédé pour effacer un élément de données d'une structure de données, qui comprend les étapes suivantes consistant à : calculer une valeur de hachage au moins sur la base de l'élément de données à effacer au sein d'une instance et remplacer l'élément de données dans la structure de données par la valeur de hachage calculée.
