In one aspect, a method includes performing, by a first server of a secure MPC system in collaboration with one or more second servers of the secure MPC system, a selection process to select a digital component based in part on a selection value for each digital component in the selection process. This includes determining a first secret share of a winner parameter for each digital component in the selection process. The first server determines, for each given digital component in the selection process and in collaboration with the second server(s), a highest other selection value that corresponds to a different digital component that is different from the given digital component.
