Abstract:
Problem statement: In recent years, as digital media are gaining wider popularity, theirsecurity related issues are becoming greater concern. Method for authenticating and assuring theintegrity of the image is required. Image authentication is possible by embedding a layer of theauthentication signature into the digital image using a digital watermark. In some applications tamperlocalization is also required. Approach: In this study, we proposed a fragile image authenticationsystem with tamper localization in wavelet domain. ....etc

Introduction

This paper explores the various techniques used to authenticate the visual data recorded by the automatic video surveillance system. Automatic video surveillance systems are used for continuous and effective monitoring and reliable control of remote and dangerous sites. Some practical issues must be taken in to account, in order to take full advantage of the potentiality of VS system. The validity of visual data acquired, processed and possibly stored by the VS system, as a proof in front of a court of law is one of such issues ....etc

Abstract
Watermarking, which belong to the information hiding field, has seen a lot of research interest recently. There is a lot of work begin conducted in different branches in this field. Steganography is used for secret conmunication, whereas watermarking is used for content protection, copyright management, content authentication and tamper detection. In this paper we present a detailed survey of existing and newly proposed steganographic and watenmarking techniques. We classify the techniques based on different domains in which ....etc

Lossless Watermarking for Image Authentication (VC++)
IEEE Transactions on Image Processing, Vol. 15, No. 4,

Abstract:
We present a novel framework for lossless (invertible) authentication watermarking, which enables zero-distortion reconstruction of the un-watermarked images upon verification. As opposed to earlier lossless authentication methods that required reconstruction of the original image prior to validation, the new framework allows validation of the watermarked images before recovery of the original image. This reduces c ....etc
