Descrição
Resumo:Over the past several decades, digital information science has emerged to seek answers to the question: can anytechnique ensure tamper-resistance and protect the copyright of digital contents by storing, transmitting andprocessing information encoded in systems where digital content can easily be disseminated through communicationchannels? Today it is understood that the answer is yes. This paper reviews the theoretical analysis and performanceinvestigation of representative watermarking systems in transform domains and geometric invariant regions. Digitalwatermarking is a technology of embedding watermark with intellectual property rights into images, videos, audios,and other multimedia data by a certain algorithm. The basic characteristics of digital watermark are imperceptibility,capacity, robustness and false positive of watermarking algorithm and security of the hiding place. Moreover, it isconcluded that various attacks operators are used for the assessment of watermarking systems, which supplies anautomated and fair analysis of substantial watermarking methods for chosen application areas.
