1.Introduction
 Information protection
 When dealing with information protection, we must distinguish between security and dependability.
 Security can be defined in terms of confidentiality, availability,integrity and authenticity .
 Dependability mostly concerns the computing system.
 It can be described as a composite of availability (of a service), reliability (continuity of service) and maintainability (ability to undergo modifications and repairs)

With the rapid growth of broadband network, distribution of
multimedia via Internet is a must way to go. Content protection
In this paper, we study the multimedia content protection by
has become one of the most significant and challenging problems

Abstract—
Medical image is usually comprised of region ofinterest (ROI) and region of non interest (RONI). ROI is theregion that contains the important information from diagnosispoint of view so it must be stored without any distortion. Wehave proposed a digital watermarking technique which avoidsthe distortion of image in ROI by embedding the watermarkinformation in RONI. The watermark is comprised of patientinformation, hospital logo and message authentication code,computed using hash function. Earlier BCH encryption ofwatermark is ....etc

Imperceptible Watermarking Algorithm Using Block LSB Scheme for Color Images
ABSTRACT
It is well known that now a dayâ„¢s more and more people are publishing papers, books, videos and photographs on the internet. The numerous properties of digital media have made copyrights violations easy. The simple replication and transmission as well as file sharing are just some examples. To overcome that the proposed technique is imperceptible watermarking algorithm using spatial domain block LSB scheme for color image authentication. Watermark i ....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

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

Automatic Segmentation of Digital Images Applied In Cardiac Medical Images
Abstract:
In this project, at the initial stage, the the segmentation is used to separate the image in parts that represents an interest object, that may be used in a specific study. There are several methods that intend to perform such task, but are difficult to find a method that can easily adapt to different type of images, that often are very complex or specific. To resolve this problem, this project aims to presents an adaptable segmentation method that ca ....etc
