{"guid":"14610aca-cb4d-4d79-915d-07ad36b32e47","title":"Anonymization workshop","subtitle":"Tipps, Tricks und Fallen","slug":"pw17-92-anonymization_workshop","link":"https://c3voc.de","description":"Big Data in Form von SmartCity und SmartLiving funktioniert nur, wenn die Algorithmen die Daten von uns allen kennen.\nDatenschutzgesetz und Bankgeheimnis stellen diese Daten aber unter ihren Schutz und fordern strenge Rechtsgrundlagen für die Nutzung,  auch im eigenen Unternehmen.\nDas erfordert angemessene Anonymisierung und Pseudonymisierung.\nJe mehr über Datenanalyse und Big Data gesprochen wird, desto mehr bekommt Anonymisierung und Pseudonymisierung an Bedeutung. \nDer Vortrag zeigt die grundlegenden Konzepte dieser beiden Techniken auf, demonstriert aber auch an Hand von vielen Beispielen, welche Fallstricke dort zu erwarten sind und welche Fehler dabei oft gemacht werden.\n\nThe workshop introduces the concept of anonymization vs pseudonymization. It shows the major mistakes that have been committed in the past when publishing anonymized data. \nFrom this, the lesson asks how each of these mistakes could have been avoided.\nThe session introduces concepts like quasi-identifier, k-anonymity, l-identity, dominance attack, and shows that it is nearly impossible to truly anonymize location data.\nThe author has plenty of experience doing anomization concepts for critical data.\n","original_language":"deu","persons":["Philipp
