Abstract

The present invention relates to communications systems, and more particularly to enabling one communications device to access data, such as a set of multimedia objects, accessible by another communications device. Identity code information is communicated between the communications devices and the server, wherein a representation of the identity code is communicated from one of the communications devices to the other of the communications devices and then to the server. The identity code is associated with data accessible by one of the communications device and the data is associated with access rights. The server is thereby able to associate specific communications devices, access rights and contents.
