Abstract: A method, in particular, a computer-implemented method, for managing data associated with a product pool including at least two technical products, in particular, machines or vehicles, using a multiparty computation (MPC) process. The method includes the following steps: receiving first input data at at least one first MPC node, the first input data including operating data of the at least one first product, and receiving second input data at an at least one second MPC node, the second input data including operating data of the at least one second product, receiving further input data at one further MPC node, the further input data including the data associated with the product pool, calculating a distribution function based on the first input data, on the second input data and on the further input data, and outputting the distribution function.
