Abstract
A typical data hiding framework is illustrated in Fig. 2.1. Starting with an original digital media (I0), which is also commonly referred to as the host media or cover media, the embedding module inserts in it a set of secondary data (b), which is referred to as embedded data or watermark, to obtain the marked media (I1). The insertion or embedding is done such that I1 is perceptually identical to the original I0. The difference between Il and I0 is the distortion introduced by the embedding process.
