Highly Secured Digital Image Watermarking Using LSB and DCT Combined Approach

Abstract

In the present time, information transmission is becoming increasingly different through digitization. The internet is windily used to sharing multimedia content quickly and accurately from one user to another user. In this process of communication, users can share their private data publicly over the internet. There is still a very useless problem; image protection is not a suitable way to recognize ownership with the image-sharing tools on the Internet. At this time, providing security and authenticity is a major concern between information transmissions. Therefore, the digital watermarking technique gives a better method to prevent illegal access, unlike exploitation and allocation and information about the copyright protection of digitized data.

In this research paper, digital image watermarking is completed by applying the combined approach of Least Significant Bit (LSB) and Discrete Cosine Transform (DCT) to evaluate the possibilities of dual watermarking.
