Methods and apparatus for anonymous identification of the profiles of subscribers in a communication system, wherein subscribers define and store subscriber-specific profiles via a respective input unit in a respective communication terminal and/or in a respective module respectively coupled to a respective communication terminal. Each respective module communication terminal is used to collect the profiles of other subscribers of the communication system on the basis of a wireless, locally defined network technology which are compared to the profiles defined and stored in the respective communication terminal whereupon they are discarded according to a subscriber-specific correlation threshold or communicated to the respective subscriber. A communication link is set up by an intermediate coupled provider of the communication system between subscribers when the respective subscriber activation occurs. A module is also disclosed that can be integrated in a mobile communication terminal or on a mobile communication terminal via an interface. The module includes a memory unit for storing profiles, a collector unit functioning on the basis of a wireless, locally defined network technology for collecting (scanning) profiles of subscribers, a correlation unit for comparing profiles, and a signaling/synchronizing unit.
