2.6 Electronic data storage on secure web-server Data security and privacy will be a priority whilst dealing with medical data such as that held in the PEPPER system. During the clinical studies (phases 1-2) anonymous clinical data will be entered and stored on a secure web-server. Anonymous data collected by the PEPPER handset (such as glucose, meal information, physical activity, alcohol, exercise) and the Dexcom CGM system will be automatically transmitted to the secure web-server. For this purpose, EU regulatory procedures (Directives 95/46/EC and 2002/58/EC) will be observed. Medical data will be stored and protected against non-authorised access; transmission of data will be secured; only authorised users will have access to services and stored data. Authentication will be required for application use and data synchronisation. PEPPER will operate according to standard interoperability guidelines (e.g. HL7), so that information can be exchanged seamlessly between the various components. Authorised users will include study team members from the PEPPER collaborators. Collaborators will only be able to view anonymous PEPPER handset data.
