【 摘 要 】

The rapid growths of computer technologies have been increased over the last half century interms of amount and complexity of data. Broadcasting of digital contents on the networks(especially Internet) has become more important and access to the data also has become mucheasier than before. Digital watermarking techniques are used to protect the copyrights ofmultimedia data by embedding secret information inside them. For example, embeddingwatermark in images, audios, and videos. Digital Image watermarking also has been using todetect original images against forged images by embedding an evidence of the owner of thedigital image. Imperceptibility, on the other hand, is one of the problems in digital imagewatermarking which a repeated method in different bit planes of cover image has been presentedto improve the imperceptibility of watermarking in both embedding and extracting processes.Moreover, embedding process aims to embed watermark in different bit planes by using a nonsequentialmethod to improve security of image rather than simple sequential embedding.
