ABSTRACT:
Digital data is prepared for storage in a secure fashion. Each data byte of a data file is encrypted. A unique bit number is assigned to each data bit in the encrypted data bytes where the bit number identifies a position of the data bit in the data file. Each such bit number is encrypted to generate a corresponding encrypted bit number. A data package is generated for each data bit. The data package includes a first data byte containing (i) a value of the data bit, and (ii) a bit storage location, at least one second data byte identifying the data file with which the data bit is associated, and at least one third data byte containing the encrypted bit number associated with the data bit. Each data package is transmitted to one of a plurality of storage locations based on the bit storage location identified in the data package's first data byte.
