With the growing popularity of digital Medias through the WWW, intellectual property needs copyright protection, prevention of illegal copying and verification of content integrity. The new data hiding techniques need to be developed that satisfy the requirements of imperceptibility, robustness, capacity, or data hiding rate and security of the hidden data in order to keep the distribution of digital multimedia work both profitable for the document owner and reliable for the customer.

Previous research [01] indicates that significant portions of the host image, e.g. the low frequency components, have to be modified in order to embed the information in a reliable and robust way. This led to the development of watermarking schemes embedding in the frequency domain. The wavelet transform has the number of advantages over other transforms such as the DCT that can be exploited for both, image compression and watermarking applications. Therefore it is imperative to consider the wavelet transform domain for watermarking applications.
