Abstract
The invention relates to a method for pooling and analyzing datasets from data providers. The method includes, at the level of each data provider, for each dataset, a first encryption of each variable of the dataset with a first encryption key common to all data providers, and a second encryption of at least each variable of the dataset with a second encryption key specific to the each data provider and shared with an intermediary. The method also includes, at the level of the intermediary, for each encrypted dataset, decryption of the variables with the second encryption key, and a third encryption of each confidential variable with a third encryption key. The method also includes transmission of the datasets encrypted with the third encryption key to an analysis environment for analysis. It also relates to a computer program and a system for implementing such a method.
