A file system stores files in a location base on deterministic nonlinear functions using certain initial conditions of the files creation. The file is chunked and encrypted according to one of a set of encryption algorithms based on the initial conditions. Only the file name and associated initial conditions are stored; the initial location and encryption algorithm are not stored and therefore not retrievable. The file system periodically relocates the files based on one of a set of algorithms based on the initial conditions such that even if the initial location where know, the file would still be irretrievable without knowing the relation between the initial conditions and relocation algorithm. During retrieval, the system uses the stored initial conditions to identify the initial location, relocation algorithm, and encryption algorithm.
