Abstract:
A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as an audio, video or image data. It is typically used to identify ownership of the copyright of such signal. Watermarking is the process of hiding digital information in a carrier signal; the hidden information should, but does not need to, contain a relation to the carrier signal. Digital watermarks may be used to verify the authenticity or integrity of the carrier signal or to show the identity of its owners. It is prominently used for tracing copyright infringements and for bank note authentication. We apply the wavelet transform and set partitioning in hierarchical transforms (SPIHT) source encoding method to efficiently compress the original image. Tampered area can be detected by using watermarking algorithm.
