摘要

The system comprises a plurality of decision units (DU), at least one verification unit (VU) and at least one aggregation unit (CU), which are functionally and structurally separate. Each decision unit comprises means for generating a source information item (S) and an identity information item (Id), means for generating a source information item And means for encrypting the item. The verification unit comprises a file B1 of the identity information of the decision units, a means for checking the identity of the decision unit in which the incoming message M1 occurs, and an anonymous RTI ID = 0.0 And a means for compiling the derived message M2. The aggregation unit receives the derived message from the verification unit and comprises means for processing these messages to compile statistics of the corresponding source information items and a file (B2) of such compiled statistics.
