All data that the survey subject enters in the online questionnaire are always encrypted during transmission. We use a certificate from the company Thawte for transmission encryption. If you are asked during the process of accessing the survey whether you wish to trust the certificate, please click “yes” or “download.” Your browser will then recognize the certificate the next time you access the page. If this does not happen automatically, you need to access your browser’s security settings to confirm the certificate individually. The survey cannot be filled out without your consent to this procedure.
