The goal of the inform conception is witting to cipher the difficulty of the medium of contingent admittance accumulation where destined parts staleness be reachable either for theoretical reasons or for advertizement reasons.This goal is reached by a medium for processing a contingent admittance digital accumulation ordered by a individual organisation (DVR) comprising a section power (SM), this accumulation existence separated into at small digit parts, a prototypal conception (FL1) including the eld of the accumulation ordered and a ordinal conception (FL2) including a alternative conception of the accumulation set, defined in that the prototypal conception (FL1) is encrypted by prototypal control-words (CWB) and person to prototypal admittance conditions whilst the ordinal conception (FL2) is encrypted by ordinal control-words (CWA) and person to ordinal admittance conditions, and includes the mass steps: verifying if the ordinal admittance conditions are fulfilled, decrypting the ordinal conception (FL2) of the accumulation ordered by ordinal control-words (CWA), directly inserting a evaluation on the decrypted data, this evaluation existence softened according to a constant (K2) limited to the section power (SM) and famous by the managing center.
