Digital watermarking is a technique of information adding or informationhiding in order to identify the owner of the data in multimedia content. Itseems that a signal or digital image can permanently embed over another digitaldata providing a good way to protect intellectual property from illegalreplication. The cover data that is transmitted through the internet hides thewatermark in a computer aided assertion method such that it becomesundetectable. Finally it stands as a hindrance over many operations withoutharming the embedded host document. Unfortunately, many owners of the digitalmaterials such as images, text, audio and video are reluctant to the spreadingof their documents on the web or other networked environment, because the easeof duplicating digital materials facilitates copyright violation. Digital mediadistribution occurs through various channels. The cover data may or may nothold any relation with the watermark information. In the last two decades, aconsiderable amount of research has been done on the digital watermarking ofmultimedia files such as audio, video, images and text. Different type ofwatermarking algorithms has been proposed by the researchers to achieve highlevel of security and authenticity. In our proposed method, a modifiedreversible watermarking technique is introduced, which employs a blueprintgeneration of original image based on odd-even embedding methodology to yieldlarge data hiding capacity, security as well as high watermarked quality. Theexperimental results demonstrate that, no matter how much secret data isembedded, the watermarked quality is about 51dB in this proposed scheme.
