  • 基于LSB的數(shù)字水印技術(shù)

    LSB數(shù)字水印技術(shù) 數(shù)字水印（Digital watermarking）技術(shù)是將一些標(biāo)識信息(即數(shù)字水印)直接嵌入數(shù)字載體當(dāng)中(包括多媒體、文檔、軟件等)或是間接表示(修改特定區(qū)域的結(jié)構(gòu))，且不影響原載體的使用價(jià)值，也不容易被探知和再次修改。但可以被生產(chǎn)方識別和辨認(rèn)。通過這些隱藏在載體中的信息，可以達(dá)到確認(rèn)內(nèi)容創(chuàng)建者、購買者、傳送隱秘信息或者判斷載體是否被篡改等目的。數(shù)字水印是信息隱藏技術(shù)的一個(gè)重要研究方向。 數(shù)字水印是實(shí)現(xiàn)版權(quán)保護(hù)的有效辦法，是信息隱藏技術(shù)研究領(lǐng)域的重要分支。作為一種新型的有效的版權(quán)保護(hù)手段，數(shù)字水印技術(shù)倍受人們的關(guān)注。數(shù)字水印主要是通過在原始資料中嵌入秘密信息——水印,來證實(shí)資料的所有權(quán)。

    This discussion will attempt to outline some truths and common misconceptions about digital audio watermarking. It will survey the intrinsic obstacles that such technology is required to overcome, shedding light on its performance criteria, compromises and limitations. While doing so, it will also survey a few common types of applications, hopefully leading to a clear understanding as to the appropriateness of such technology and its expertise within multimedia content protection.

    During the past four years, most of our research activities have been focused on image but also video and 3-D objects processing for security applications (watermarking and biometrics) and communications (talking heads, interfaces), with a special emphasis on facial images. More about our work can be found at http://www.eurecom.fr/~image. Our research activities are conducted with the backing of several industrials, in particular France Telecom Research and STMicroelectronics. For the past few years, we have had a regular scientific collaboration on Fractal Image Coding, watermarking and Biometrics with the University of California, Santa Barbara (UCSB), in particular with Prof. K. Ros
