 Protecting individuals' personal data is an integral part of protecting their life and dignity. This is why personal data protection is of fundamental importance for humanitarian organisations. The International Committee of the Red Cross teamed up with the Brussels Privacy Hub to bring together leading experts on data protection to produce a practical guide to the issues facing humanitarian organisations. The Handbook on Data Protection in Humanitarian Action seeks to raise awareness and assist humanitarian organisations in ensuring that they comply with personal data protection standards when carrying out their activities. After an initial analysis of the application of data protection principles to humanitarian action, the Handbook considers the data protection implications of using specific new technologies in the humanitarian sector. These include data analytics, drones, biometrics, cash transfer programming, cloud computing services and messaging apps.
