Digital Image Watermarking Seminar Topic

Introduction

Digital image watermarking is a technique used to protect the ownership and integrity of digital images. It involves embedding a watermark into the image in such a way that it is imperceptible to the human eye but can be detected and extracted by specific algorithms. This technology has gained significant importance in recent years due to the widespread use of digital images on the internet and the ease of unauthorized copying and distribution.

Problem Statement

The main challenge in digital image watermarking is to ensure that the watermark is robust against various transformations such as compression, cropping, and noise addition while maintaining the visual quality of the image. Existing watermarking techniques often struggle to strike a balance between robustness and imperceptibility, leading to the degradation of image quality and the vulnerability of the watermark to attacks.

Existing System

The existing digital image watermarking systems typically use techniques such as spatial domain, frequency domain, and transform domain methods to embed the watermark into the image. These techniques have their advantages and disadvantages, with some being more suitable for certain types of images or applications. However, a common drawback of existing systems is their limited robustness and susceptibility to attacks, leading to the unauthorized removal or alteration of the watermark.

Disadvantages

– Degradation of image quality
– Vulnerability to attacks
– Limited robustness against transformations
– Difficulty in achieving imperceptibility
