A data transfer client device comprising: memory for storing at least one dataset comprising a plurality of data fields and at least one filter definition comprising data defining which of the data fields can be accessed by a particular server; an interface for communicating with a data transfer server, whereby a data transfer server can access a dataset stored in the memory; and a data transfer controller for policing access during a data transfer operation by a data transfer server to the data fields, the data transfer controller being arranged to determine in dependence on the filter definition whether the data transfer server can access particular data fields and to deny the server access to those data fields to which the data transfer controller determines that the data transfer server cannot have access. |
