An open system for dynamically generating a network of contacts, wherein the network is implemented as levels in a tree that is propagated incrementally as a function of each given search from a user of a level "zero" to one or more final entities or "leaves" unknown to the user and satisfying search criteria, propagation taking place via entities of a level "1" forming a first network of acquaintances that are known directly and/or indirectly to the user, and via one or more intermediary entities of levels "n", unknown to the user and each having a respective network of acquaintances formed by contacts with entities of levels "n+1", the system including a filter which is run at each incremental level by removing duplication of contacts with entities so that each entity of level "n+1" in the chain refers to a unique entity of level "n" forming a linear reverse propagation.
