SYSTEM AND A COMPUTER-IMPLEMENTED METHOD FOR DECODING DATA WHEN SWITCHING BETWEEN JURISDICTIONS IN PAYMENT SYSTEMS

摘要

FIELD: information technology.;SUBSTANCE: invention relates to means of decoding financial transaction data during their switching by means of switching service between acquirer and issuer, which are located in different countries. In the method, the acquirer host sends a personalized transaction to an anonymization service through an independent communication channel which anonymizes the transaction and sends it back to the acquirer host, and also sends a reverse anonymization dictionary to the issuer host, which sends an anonymous transaction to the acquirer interface, which sends it through the switching service to the issuer interface, which sends it to the issuer host. Issuer host uses a dictionary to re-personalize the transaction, processes the personalized transaction again and sends a response code to the acquirer host. Service and the acquirer interface can independently calculate the hash value and the acquirer interface can send an anonymous transaction only if the values match.;EFFECT: wider range of equipment.;16 cl, 4 dwg
