Abstract
Methods of transaction authentication are provided. In one such method, at least one first transaction has been conducted, the or each first transaction generating data including first data comprising authentication data and second data identifying the or each first transaction, wherein a given first transaction is between a merchant and a card holder. A cryptographically signed and/or encrypted token corresponding to the given first transaction and comprising a characteristic of the first transaction has been generated using at least said second data. The cryptographically signed and/or encrypted token has been transmitted to the merchant. The method comprises receiving, from the merchant, data corresponding to a second transaction and in the event that the data corresponding to the second transaction includes the cryptographically signed and/or encrypted token, responsively authenticating the cryptographically signed and/or encrypted token, whereby to determine an authenticated association between the second transaction and a given first transaction.
