DataSHIELD is a software solution for secure bioscience collaboration.
Analysis requests are sent from a central analysis machine to several data-holding machines storing the harmonised data to be co-analysed. The data sets are analysed simultaneously but in parallel, linked by non-disclosive summary statistics. Analysis is taken to the data – not the data to the analysis.
