The CERS Dataroom, created by the CERS Databank started its operations in June 2021, where researchers can work on such data that cannot be accessed in an external environment. The Dataroom provides a secure environment in accordance with the research ethics and data-use principles required for prestigious international publications. At present, access is mainly available to detailed health data and to the input file of the Linked Administrative Panel Dataset (Admin3), but other data sources can be involved too, on request. The Dataroom provides access to the datasets for scientific purposes only, with a high level of protection of individual statistical data and in strict compliance with data protection legislation. Only mass phenomena can be investigated in the Dataroom. Research projects that risk the discovery of individual natural units cannot be launched. Researchers can use the Dataroom in a secure IT environment where camera monitoring surveillance system operates. Results can be released after a data protection check by the Databank staff.
