Abstract

The internet is an outstanding distribution and sales channel for digital assets, but copyright compliance and content management can be a challenge. If you distribute electronic images, be it online or CDs and other portable media, you are risking digital piracy. These days, digital images can be utilized - with or without consent everywhere. For the consent of the person's authentication and copyright, in this paper a digital image watermarking is proposed. The suggested digital watermarking is a method which allows a person to add invisible copyright images or notices or text messages to image and documents. In this paper, a invisible watermarking is proposed for authentication and copyright protection. This mechanism calculates the checksum for watermark and embedded within the original image at random pixels. This mechanism does not disturb the original image quality and key factors. So that intruder or unauthorized person does not identifying hiding information. From the results of the experiment, it is also observed that proposed method not only produces the quality watermarked images but also produces the quality check sum that will used for authentication.
