Claim 1:
2. The computer-implemented method of claim 1 for improving the function of the computer for depersonalizing transactions being switched between the acquirer system located in the first country and the issuer system located in the second country by the switching service during the financial transaction, wherein the acquirer system includes an acquirer's authorization host and an acquirer's interface processor, and the issuer system includes an issuer's authorization host and an issuer's interface processor, the method further comprising:
sending the personalized particular transaction and the associated transaction identification from the acquirer's authorization host located in the first country to the depersonalization service via the independent communications channel which is independent of the switching service;
depersonalizing the personalized particular transaction at the depersonalization service to produce the depersonalized particular transaction;
sending the transaction identification from the depersonalization service to the acquirer's interface processor located in the first country;
sending the depersonalized particular transaction from the depersonalization service to the acquirer's authorization host located in the first country;
sending the transaction identification and the reverse depersonalization dictionary from the depersonalization service to the issuer's authorization host located in the second country;
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 country to the issuer's interface processor located in the second country via the 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 country using the reverse depersonalization dictionary to produce the repersonalized particular transaction;
processing the repersonalized particular transaction at the issuer's authorization host;
sending the 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 country to the acquirer's authorization host located in the first country 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.
