Digital Watermarking Techniques: A Survey
Keywords:
Discrete cosine transform, Digital watermarking, Discrete wavelet transform, Multi-purpose blind watermarking algorithmAbstract
In today’s situation because the technology is advancing, therefore exponentially threats of cyber crimes are
also increasing. So, to protect our contents from these threats we'd like Digital watermarking. Here, we are going to
study concerning the Digital Watermarking. We are going to watermark a color image into a host image. For color
digital image a multipurpose blind watermarking algorithm based on discrete wavelet transform (DWT) and discrete
cosine transform (DCT) is projected in maintenance with the need of multipurpose blind watermarking algorithm. The
most important objective is to be told regarding different kinds of watermarking techniqu es, which may be utilized in
day-after-day lives. In today’s scenario because the technology is advancing with time, therefore exponentially threats of
cyber crimes are also increasing alarmingly. So, to protect our contents from these threats we'd like Di gital
watermarking. Digital watermarking applications are copyright protection, authentication and security.
