Introduction
Steganography is derived from the Greek for covered writing and essentially means to hide
in plain sight. As defined by Cachin steganography is the art and science of
communicating in such a way that the presence of a message cannot be detected. Simple
steganographic techniques have been in use for hundreds of years, but with the increasing
use of files in an electronic format new techniques for information hiding have become
possible.
This document will examine some early examples of steganography and the general ....etc

 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)

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

With the rapid growth of Internet and networks technique, multimedia data transforming and sharing is common to many people. Multimedia data is easily copied and modified, so necessity for copyright protection is increasing. It is the imperceptible marking of multimedia data to brand ownership. Digital watermarking has been proposed as technique for copyright protection of multimedia data. Digital watermarking invisibly embeds copyright information into multimedia data. Thus, digital watermarking has been used for copyright protection, finger ....etc

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
