A method for redundantly securing data using an array of at least two independent partner networks, each network being composed of a plurality of digital components, the method comprising the steps of: (a) upon receiving a storage request and secret data for securely storing said secret data, cryptographically splitting said secret data by independently requesting random data from each of at least one independent partner network out of an array of at least two independent partner networks, wherein said random data are one-time data items; (b) independently receiving said random data from each of said at least one independent partner network, wherein respective random data is stored on a respective independent partner network; (c) cumulatively calculating complementary data as an encrypted form of said secret data with a complement function using said random data; and (d) sending said complementary data to an independent storage partner network for storage, wherein said independent storage partner network is part of said array, and wherein said independent storage partner network is independent from said at least one independent partner network; and wherein authentication and authorization are distributed in a way that access control over each and every said one-time data item, and in turn said complementary data in said independent storage partner network, is independently governed by a separate, respective, independent partner network corresponding to the one-time data item, or said complementary data, under its control; wherein said cryptographically splitting ensures that each independent partner network of said array has zero knowledge of the actual data that said array cumulatively holds; and wherein said zero knowledge is defined to mean that said one-time data items stored in any given independent partner network, and said complementary data in said independent storage partner network, are meaningless random values to said given independent partner network or said independent storage partner network, preventing said given independent partner network or said independent storage partner network from obtaining, decrypting, or exposing said secret data.
