Abstract: Method and system for dynamic management of viewable digital contents (CD_ij), in which arranging a modular interface (11) comprising principal digital modules (Pi) and derived digital modules (Dij) extending prevalently in a first direction (d1); translating at least one of the principal digital modules (Pi) along a first path (t1) so that the principal digital modules (Pi) overlap at least partially; expanding the principal digital modules (Pi) along a second path (t2); selecting a viewable digital content; expanding the selected viewable digital content (CD_ij) along a third path (t3), determining at least a first derived digital module (Dij), in which translating at least one of the principal digital modules (Pi) along the first path (t1), expanding the principal digital modules (Pi) along the second path (t2) and expanding the selected viewable digital content (CD_ij) along the third path (t3) determine selective dynamic accessibility to the viewable digital contents (CD_ij) on the modular interface (11)

Abstract: A certified identification system for a subject is described. The system has a certification station configured to issue first identification means representing the subject, second identification means, suitable for identifying at least one identification station, and configured to be associated with the subject, wherein the identification station is configured to combine the identification means and the first code of the second identification means, issuing a unique identification code comprising first data, a second code and a first code, wherein the identification station (4) further includes an encapsulation module configured to encapsulate the identification data so that they are presented as compact data.
