Abstract
(EN)
There is provided a computer-implemented method of authenticating an interaction carried out between a mobile device and a gateway, the method being carried out by an authentication system remote from the mobile device and the gateway. The method comprises the steps of: receiving one or more first data items from the gateway, the one or more first data items including dynamic data corresponding to one or more second data items uniquely identifying the interaction, wherein one of the second data items corresponds to a portion of a counter value associated with the interaction; and extracting the counter value portion from the dynamic data. The method further comprises calculating one or more candidate counter values which could correspond to the counter value associated with the interaction; generating, for each of the one or more candidate counter values, a piece of corresponding candidate dynamic data based on one or more of the other first data items; and comparing each of the candidate dynamic data to the received dynamic data to ascertain whether a match is obtained.
