Claim 5:
6. The computer-implemented method of claim 2, further including—
calculating a first hash value for the depersonalized particular transaction at the depersonalization service;
sending the first hash value along with the transaction identification from the depersonalization service to the acquirer's interface processor;
calculating a second hash value for the depersonalized particular transaction at the acquirer's interface processor;
comparing the first hash value to the second hash value at the acquirer's interface processor, and if the first hash value does not match the second hash value, rejecting the depersonalized particular transaction at the acquirer's interface processor, and sending a reason code from the acquirer's interface processor to the acquirer's authorization host; and
if the first hash value matches the second hash value, 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.
