Abstract

A wide range of watermarking evaluation approaches and especially image benchmarking suites have been described in the literature. Our paper sets the main focus on the evaluation of digital audio watermarking with StirMark Benchmark for Audio (SMBA). Here we describe the currently implemented single geometric attacks in detail and introduce our so-called attack profiles. Profiles reflect an application oriented point of view ranging from the normal usage of audio content like internet radio or music shops up to typical attacker scenarios. In particular we present a definition of an extended profile which is composed of three basic profiles specific for annotation watermarks. Furthermore, we demonstrate how SMBA attacks can be used to evaluate the transparency of digital watermarking algorithms regarding the embedding strength. Test results based on an example audio watermarking algorithm and the measurement of transparency and capacity are presented.
