Claim 18:
19. The apparatus of claim 16 further comprising:
the first requestor generates at least one of the at least one reversible token, at least in part, via combining of at least:
source data input that is supplied by the first requestor in ephemerally blinded form, blinded using a first blinding factor that is independently generated by the first requestor, and that is further ephemerally blinded by the first tokenization processor via a second blinding factor that is independently generated by the first tokenization processor, and that is further ephemerally blinded by the second tokenization processor via a third blinding factor that is independently generated by the second tokenization processor;
a scope-dependent first output of the first tokenization processor that is invariant of the source data input and of the first blinding factor; and
a scope-dependent second output of the second tokenization processor that is invariant of the source data input and of the first blinding factor;
wherein the apparatus computes the first output as:
a first function of the second blinding factor; and
a second function of tokenization processor secrets that include at least one tokenization processor secret of the first tokenization processor and at least one tokenization processor secret of the second tokenization processor;
and wherein the apparatus computes the second output as:
a third function of the third blinding factor; and
a fourth function of the tokenization processor secrets that include at least one tokenization processor secret of the first tokenization processor and at least one tokenization processor secret of the second tokenization processor; and
wherein the first output and the second output are distinct from one another.
