In recent years we have seen many initiatives to provide electronic music delivery (EMD) services. We observe that a key success factor in EMD is the transparency of the distribution service. We could compare it with the traditional music distribution via compact discs. By buying a CD, a user acquires a 'free' control of the content, i.e. he can copy it, he can play it multiple times etc. In the electronic equivalent, the usage and digital rights management rules should be transparent, and preferably comparable to the classical method of distributing contents. It is the goal of this paper to describe a technology concept that facilitates, from a consumer perspective simple EMD service. Digital watermarking and fingerprinting are the two key technologies involved. The watermarking technology is used to convey the information that uniquely identifies a specific transaction, and the fingerprint technology is adopted for key management and security purposes. In this paper, we discuss how these two technologies are integrated in such a way that watermark security (i.e. the inability to maliciously alter the watermark) and distribution efficiency (i.e. the ability to serve multiple consumers with one distribution PC) are maximized.
