1. A digital signature generation apparatus comprising:

  • a polarizer operable to produce a two-state signal having a bit sequence providing a binary representation of a sampled data segment;

    an event detector operable to identify at least one event in the sampled data segment or in the two-state signal; and

    a signature generator operable, on the basis of a predetermined signature collection pattern specifying a plurality of offsets from an identified event to select the values of the respective bits of the bit sequence at the bit positions specified by the offsets, and on the basis of those values to provide a digital signature characteristic of the sampled data segment.
