Abstract

A method is provided of retrieving one or more data items stored in a protected area of a remote server for transferral to a local device. A trusted connection is formed between an information device and the protected area of the remote server. The information device and the trusted connection are employed to select a first group of one or more data items stored in the protected area of the remote server. The first group of data items are transferred from the protected area to a holding area outside the protected area of the remote server. A retrieval connection is formed between the local device and the holding area. A second group of one or more data items is determined from the first group of data items transferred to the holding area. The second group of data items is transferred from the holding area to the local device over the retrieval connection.
