1. A system for uploading and storing a plurality of information data files on a remote storage in association with a corresponding plurality of different indices, wherein each information data file includes location information that is indicative of a location of an electronic device, comprising:

  • (a) a location module that is executed on the electronic device and determines the location information for the electronic device;

    (b) a core module that is executed on the electronic device and which determines a plurality of different states for the core module over time, each state being determined by the core module as a function of a previous state and being used by the core module to determine an index that will be associated with a current information data file when the current information data file is stored on the remote storage, the core module thereby storing a succession of indices and corresponding information data files on the remote storage over time; and

    (c) a retrieval module that can be executed on a different device, the retrieval module using an initial state for the core module to determine the plurality of different states, so that an index that was associated with a desired information data file when the desired information data file was stored on the remote storage can be determined by the retrieval module, enabling the desired information data file to be retrieved from the remote storage, to access the location information and any other information included therein that is indicative of the location of the electronic device.
