1. A computer implemented method embodied in data structures stored in a computer-readable medium to execute the following steps:

  • selecting an elliptic curve method;

    executing a point modification algorithm to manipulate points of the elliptic curve method,wherein the point modification algorithm includes at least five occurrences of point fractioning, with inputs to said at least five occurrences after a first depending directly or indirectly on results from a previous occurrence;

    generating a signal having a distinct characteristic using the selected elliptic curve method;

    providing substantive content; and

    manipulating the substantive content using the distinct characteristic.
