1. A hand-held device, said device for masking non-public data elements in uniform resource identifiers, said hand-held device comprising:

  • a resource;

    a uniform resource identifier (“

    URI”

    ), which is configured to identify the resource;

    a processor, on said hand-held device, said processor configured to determine, within said hand-held device, the presence of a non-public data element in the URI;

    the processor further configured to generate a random number, within said hand-held device, wherein the length of the random number is at least as long as the length of the non-public data element, in response to the determination of the presence of the non-public data element;

    the processor further configured to compute, within said hand-held device, a resultant number based on the exclusive disjunction of the random number and the non-public data element; and

    the processor further configured to substitute, within said hand-held device, the resultant number for the non-public data element in the URI, said substituting occurring prior to transmission of the URI to a server.
