Steganography is a technique for hiding secret information within other files like images, audio or video. It works by concealing a file within another file so that the existence of the hidden message is undetectable. Some advantages are that it preserves secret information from others and can be applied to digital media without detection. A disadvantage is that encoding very large files may create suspicion.

Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. It works by hiding secret information in places where an observer would not easily notice. Historically, steganography techniques have included tattooing messages on shaved heads and using invisible ink between the lines of otherwise normal text. Modern methods embed data in the least significant bits of images, audio files, or video frames. Steganography provides a way to secretly communicate while avoiding detection from those not intended to receive the message.
Steganography ppt
Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. The concealed message is hidden in a way that prevents detection. It differs from cryptography, which encrypts a message to hide its meaning but not its existence. Modern steganography techniques include least significant bit insertion to hide messages in image files with minimal distortion. Detection of concealed messages is called steganalysis and involves visual or statistical analysis to reveal alterations caused by message embedding.

Presentation On Steganography
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.

Examples are provided to illustrate how the LSB technique works.
Cryptography and Steganography with watermarking
This document discusses different digital security techniques including cryptography, steganography, and watermarking. Cryptography involves encrypting messages to hide their meaning and can provide confidentiality, integrity, and authentication. Steganography embeds hidden messages within ordinary files like images or audio so the very existence of the message is concealed. Watermarking similarly embeds invisible signatures or markings within files but is intended to identify ownership rather than conceal messages. Both steganography and watermarking can apply techniques like modifying least significant bits of image pixel data.

A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Recycled Concrete Aggregate in Construction Part II
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Steganography
- 1. Image Steganography using LSB insertion
- 2. Introduction 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".
- 3. Advantages of Steganography • Preserving secret information that is hidden from others • Can be applied on digital image,audio and Video • Unsuspicious, as no one can detect.
- 4. Disadvantage of Steganography • Huge file can be encoded into file as this might create suspicion.
- 6. Thank you
