Detection of Tampered Images using Watermarking Technique

Abstract

Over the most recent couple of years there is a gigantic improvement in advanced innovation . Most the data is in the form of images, videos and audios. But there are various software’s to modify these images. So the data we transmit through the digital images may not be secure. For example if we are using an image as an evidence then there may be a chance of modifying that image. There may be a risk of using a digital image as evidence. So, it’s not secure to use digital images as evidence. So we decided to do a research on technology that provide security to tampered images. But there are many technologies to detect tampered images. Our project mainly focused on watermarking technique to detect tampered images.
