Abstract:
Digital watermark has been presently utilized as a possible solution for intellectual property rights protection. It is a technique for labeling multimedia data, including digital images, text documents, video and audio clips, by hiding secret information in the data. This embedded hidden information is unperceivable so the watermarked data appear identical to the original non-watermarked data. Moreover, this hidden information can neither be removed nor decoded without the required secret keys or algorithms. The current classical algorithm contains spatial domain algorithm and transformed domain algorithm. With the spatial domain algorithm, the embedding and the distilling of watermarking are finished in spatial domain, by emending directly or comparing the gray-level value or colour value. The classical spatial domain algorithms including several ways as follow: the least significant bit(LSB), Patchwork method with streak block map decoding, the method based on district intersecting and so on. Then the main current transformed domain algorithms are spread spectrum, DCT transformation method and DWT transform method.
