DIGITAL WATERMARKING IN THE WAVELET TRANSFORM DOMAIN

[Academic_Project Reports]

ABSTRACT
The wide spread communication of multimedia data has made the management of information more challenging, especially in the field of digital imaging. Where large images are to be transmitted and also stored.

Digital image watermarking is one of the latest techniques which is used for safeguarding the origins of the image by protecting it against Piracy

This project the information is visible in the picture or video.Typically, the information is text or a logo which identifies the owner of the media. The image on the right has a visible watermark. When a television broadcaster adds its logo to the corner of transmitted video.

INTRODUCTION

Digital image watermarking is one of the latest techniques which is used for safeguarding the origins of the image by protecting it against Piracy.

Watermark is a set of identifying information that is either visibly or invisibly imprinted on a host image in order to identify the origin of the host image.

1.1 Types of Watermark in terms of Fidelity

• Fragile Watermark

This watermark is mainly used for detecting modification of data. This watermark gets degraded even for a slight modification of data in the image.

• Robust Watermark

This watermark has the ability to withstand various image attacks thus providing authentication.

• Semi-Fragile Watermark

It is an intermediate between fragile and robust watermarks. It is not robust against all possible image attacks.
