  Digital watermarking is a technique of information adding or information
hiding in order to identify the owner of the data in multimedia content. It
seems that a signal or digital image can permanently embed over another digital
data providing a good way to protect intellectual property from illegal
replication. The cover data that is transmitted through the internet hides the
watermark in a computer aided assertion method such that it becomes
undetectable. Finally it stands as a hindrance over many operations without
harming the embedded host document. Unfortunately, many owners of the digital
materials such as images, text, audio and video are reluctant to the spreading
of their documents on the web or other networked environment, because the ease
of duplicating digital materials facilitates copyright violation. Digital media
distribution occurs through various channels. The cover data may or may not
hold any relation with the watermark information. In the last two decades, a
considerable amount of research has been done on the digital watermarking of
multimedia files such as audio, video, images and text. Different type of
watermarking algorithms has been proposed by the researchers to achieve high
level of security and authenticity. In our proposed method, a modified
reversible watermarking technique is introduced, which employs a blueprint
generation of original image based on odd-even embedding methodology to yield
large data hiding capacity, security as well as high watermarked quality. The
experimental results demonstrate that, no matter how much secret data is
embedded, the watermarked quality is about 51dB in this proposed scheme.
