Method to search for affinities between subjects and relative apparatus

Abstract

A method to search for affinities between subjects comprises registering a user with a certification authority, receiving first information relating to the user, memorizing the first information in a portable electronic device of the user, and synthesizing the first information by transmitting it to a user interface which processes the first information memorized. The method also comprises encrypting the first information and memorizing the first information encrypted in the portable electronic device, disseminating the first encrypted information to other portable electronic devices in geographical proximity, collecting second encrypted information relating to other users, sent from other portable electronic devices in geographical proximity and decrypting the first and second information encrypted at the certification authority. Finally, the method provides for processing and analyzing the first and second decrypted information, in order to identify affinities between them, at the certification authority, and notifying the affinities, by the certification authority.
