1. A method to generate fine granular integrity to huge volumes of data in real time at a very low computational cost for use with a computer the method comprising:

  • receiving original data from multiple sources, locally or via the network using predetermined protocols;

    processing the original data by cryptographic means for generating one or more immutable digital chains that contain at least integrity information related to the original data including timestamps; and

    communicating said digital chains to a destination, said destination being one of;

    the same as the sender of the original data, a different destination or a storage media,wherein a chained and chronologically ordered list of active chains is provided;

    every time immutable digital chains are generated or closed the list is updated as follows;

    a. Updating the latest flag of the latest chain list to false, and re-computing its digital signature;

    b. Adding a new chain list, with the latest flag set to true, an index set to one plus the index of the previous chain list, a timestamp, the list of active chains at the moment, and a digital signature of the concatenation of the digital signature of the previous chain list and the said contents of the new active chain list.
