Claim 6:
7. A computer-implemented method for improving the function of a computer for depersonalizing transactions being switched between an acquirer located in a first jurisdiction and an issuer located in a second jurisdiction by a switching service during a financial transaction, the computer-implemented method comprising:
sending a personalized particular transaction and an associated transaction identification from an acquirer's authorization host located in the first jurisdiction to a depersonalization service via an independent communications channel which is independent of the switching service;
depersonalizing the personalized particular transaction at the depersonalization service to produce a depersonalized particular transaction;
sending the transaction identification from the depersonalization service to the acquirer's interface processor located in the first jurisdiction;
sending the depersonalized particular transaction from the depersonalization service to the acquirer's authorization host located in the first jurisdiction;
sending the transaction identification and a reverse depersonalization dictionary from the depersonalization service to an issuer's authorization host located in the second jurisdiction;
sending the depersonalized particular transaction from the acquirer's authorization host to the acquirer's interface processor;
sending the depersonalized particular transaction from the acquirer's interface processor located in the first jurisdiction to the issuer's interface processor located in the second jurisdiction via a communications network operated by the switching service;
sending the depersonalized particular transaction from the issuer's interface processor to the issuer's authorization host;
reversing the depersonalization of the depersonalized particular transaction at the issuer's authorization host located in the second jurisdiction using the reverse depersonalization dictionary to produce a repersonalized particular transaction;
processing the repersonalized particular transaction at the issuer's authorization host;
sending a normal response code from the issuer's authorization host to the issuer's interface processor; and
sending the normal response code from the issuer's interface processor located in the second jurisdiction to the acquirer's authorization host located in the first jurisdiction and to the depersonalization service,
wherein neither the personalized particular transaction nor the repersonalized particular transaction are sent between the first country and the second country.
