Abstract
Digital watermarking is used to hide the information inside a
signal, which can not be easily extracted by the third party.
Its widely used application is copyright protection of digital
information. It is different from the encryption in the sense
that it allows the user to access, view and interpret the signal
but protect the ownership of the content. One of the current
research areas is to protect digital watermark inside the
information so that ownership of the information cannot be
claimed by third party. With a lot of information available on
various search engines, to protect the ownership of
information is a crucial area of research. In latest years,
several digital watermarking techniques are presented based
on discrete cosine transform (DCT), discrete wavelets
transform (DWT) and discrete fourier transforms (DFT). In
this paper, we propose an algorithm for digital image
watermarking technique based on singular value
decomposition; both of the L and U components are explored
for watermarking algorithm. This technique refers to the
watermark embedding algorithm and watermark extracting
algorithm. The experimental results prove that the quality of
the watermarked image is excellent and there is strong
resistant against many geometrical attacks.
