Steganography (US Listeni/ˌstɛ.ɡʌnˈɔː.ɡrʌ.fi/, UK /ˌstɛɡ.ənˈɒɡ.rə.fi/) is the practice of concealing a file, message, image, or video within another file, message, image, or video. The word steganography combines the Greek words steganos (στεγανός), meaning "covered, concealed, or protected", and graphein (γράφειν) meaning "writing"
Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. The word steganography combines the Greek words steganos meaning "covered, concealed, or protected", and graphein meaning "writing".
The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography, disguised as a book on magic. Generally, the hidden messages appear to be (or be part of) something else: images, articles, shopping lists, or some other cover text. For example, the hidden message may be in invisible ink between the visible lines of a private letter. Some implementations of steganography that lack a shared secret are forms of security through obscurity, whereas key-dependent steganographic schemes adhere to Kerckhoffs's principle.
The advantage of steganography over cryptography alone is that the intended secret message does not attract attention to itself as an object of scrutiny. Plainly visible encrypted messages—no matter how unbreakable—arouse interest, and may in themselves be incriminating in countries where encryption is illegal.Thus, whereas cryptography is the practice of protecting the contents of a message alone, steganography is concerned with concealing the fact that a secret message is being sent, as well as concealing the contents of the message.
Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol. Media files are ideal for steganographic transmission because of their large size. For example, a sender might start with an innocuous image file and adjust the color of every 100th pixel to correspond to a letter in the alphabet, a change so subtle that someone not specifically looking for it is unlikely to notice it.
This presentation provides an introduction to the Data hiding or Steganography topic, it also shows the types of Steganography, advantages and the related applications.
Steganography and Its Applications in SecurityIJMER
ABSTRACT: Steganography is the dark cousin of cryptography, the use of codes. While cryptography provides privacy,
steganography is intended to provide secrecy. Steganography is a method of covertly communicating. Steganography is a
process that involves hiding a message in an appropriate carrier for example an image or an audio file. The carrier can then
be sent to a receiver without anyone else knowing that it contains a hidden message. This is a process, which can be used for
example by civil rights organizations in repressive states to communicate their message to the outside world without their
own government being aware of it. In this article we have tried to elucidate the different approaches towards implementation
of Steganography using ‘multimedia’ file (text, static image, audio and video). Steganalysis is a newly emerging branch of
data processing that seeks the identification of steganographic covers, and if possible message extraction. It is similar to
cryptanalysis in cryptography. The technique is ancient emerging monster that have gained immutable notice as it have
newly penetrated the world of digital communication security. Objective is not only to prevent the message being read but
also to hide its existence.

Cryptography is the science of using mathematics to encrypt and decrypt data.
Cryptography enables you to store sensitive information or transmit it across insecure networks so that it cannot be read by anyone except the intended recipient.
Steganography in digital image processing is viewed as a future technology, in processing image and hidden techniques behind sending an image secretly by covering it up something.
We are now in mid of 2012. As predicted by many techno geeks, this year is phenomenal for IT related technologies including security, networking and web technologies. In April cloud war is started between two big rivals Microsoft & Google. Both making sure that its going to be secure and useful for smart phone users as well. With introduction of new such technologies we must ensure security over the web. Here HTTPS comes into picture and we brought this topic in CHMag's Mom's guide. Along with it topics like Steganography(Tech Gyan), a new toolkit - Kautilya(Tool Gyan), preventing SQL injections(Code Gyan) are covered.

Video Steganography using Discrete Wavelet Transform and Artificial Intelligenceijtsrd
Several developments in the transfer of data through the internet make it easier to transfer the data faster and accurately to the destination. But in this, anyone can misuse and modify the critical information through hacking. Video steganography is a technique which is used to hide the message and to transfer the message inside a video. Video is an application of many frames of audio, text, and images. The segmentation is known as the advanced technology that provides rich information of an image. The purpose of this paper is to propose a new technique to hide the data using video steganography with the help of artificial intelligence and DWT. This paper focuses on analyzing the various video steganography techniques which were proposed for securing the data transmission. In this paper, artificial intelligence is applied in order to improve the integrity and security of data transfer. The performance of the proposed method is evaluated on the basis of Bit error, mean square error, and PSNR metrics.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
