WHY ?
• Digitally sign user’s images/photos.
• Claim and maintain the recognition.
• Avoid the conflicts and headaches with plagiarists who claim they didn't know that yours.
• Proof of ownership.
Introduction
Aim
To develop an application that can help to protect the
the images uploaded by smartphone user on the internet.
identity, ownership and copyright of
Introduction
Objectives
i.
To study digital image watermarking techniques and the current system.
ii.
To design and develop a digital image watermarking application.
iii. To test the developed application.
Introduction
Scope
i.
This project focuses on digital image watermarking on jpeg formatted images.
ii.
The application are developed specifically for Android-based smartphone only.
iii. Focuses only on image taken using smartphone’s
camera.
