Abstract: There is provided an intermediary server system for providing data for use in authenticating an interaction between the mobile device and a gateway. This server system comprises: an input configured to receive, from the mobile device, interaction data comprising a plurality of interaction data items associated with the interaction and a security identifier uniquely identifying the interaction. The server system further comprises a processor configured with instructions that when executed cause the processor to: generate a request for reference data to be associated with the security identifier, the request comprising at least one of the plurality of interaction data items and the security identifier; transmit, to a remote authentication server, the generated request; receive, from the remote authentication server, the dynamic reference data; and alter the received interaction data by replacing at least one of the plurality of interaction data items with the dynamic reference data. The server system further comprises an output configured to transmit, to the gateway, the altered interaction data.
