A deception framework for survivability against next generation
Over the years, malicious entities in cyber-space have grown smarter and resourceful. For defenders to stay abreast of the increasingly sophisticated attacks, the need is to understand these attacks. In this paper, we study the current trends in security attacks and present a threat model that encapsulates their sophistication. Survivability is difficult to achieve because of its contradictory requirements. It requires that a critical system survives all attacks (including zero-day attacks), while still conserving the timeliness property of its mission. We recognize deception as an important tool to resolve this conflict.
The proposed deception-based framework predicts an attacker’s intent in order to design a stronger and more effective recovery; hence strengthening system survivability. Each design choice is supported by evidence and a detailed review of existing literature. Finally, we discuss the challenges in implementing such a framework and the directions that can be taken to overcome them.
Data Security Using Audio Steganography
Steganography is the art and science of writing hidden messages in such a way that no
one, apart from the sender and intended recipient, suspects the existence of the message,
a form of security through obscurity. Steganography works by replacing bits of useless or
unused data in regular computer files (such as graphics, sound, text, HTML, or even
floppy disks ) with bits of different, invisible information. This hidden information can
be plain text, cipher text, or even images.
In a computer-based audio Steganography system, secret messages are embedded in
digital sound. The secret message is embedded by slightly altering the binary sequence of
a sound file. Existing audio Steganography software can embed messages in WAV, AU,
and even MP3 sound files. Embedding secret messages in digital sound is usually a more
difficult process than embedding messages in other media, such as digital images. These
methods range from rather simple algorithms that insert information in the form of signal
noise to more powerful methods that exploit sophisticated signal processing techniques
to hide information.
Data Hiding in Audio Signals
Nowadays, several methods are used for communicating secret messages for defense purposes or in order to ensure the privacy of communication between two parties. So we go for hiding information in ways that prevent its detection.

Enhancement of Data Hiding Capacity in Audio Steganography
This document discusses enhancing data hiding capacity in audio steganography. It begins by introducing steganography and its use of hiding secret information in carrier files like images, audio and video. Specifically for audio steganography, it hides data in the least significant bits of audio files. The document proposes a method to enhance capacity by using the last 4 least significant bits instead of just 1, allowing more data to be hidden. It describes the basic process of audio steganography including embedding a secret message into an audio file using a key, and then extracting the message from the stego file at the receiving end.
An Approach for Securing Voice Communication via Image Watermarking Technique
Nowadays, Internet users use many social websites for communication with each other, and some of the users may live in another part of the world. Thus, communication becomes much easier and faster. However, with internet growing and their users, it becomes more likely to be attacked by hackers and intruders to access people personal data. Also, some professional hackers can detect the entire communication component for instance; text, image, video and voice messages.
In this paper, it is focused on one component, which is voice communication; and the main idea of this work is to hide the voice message that generated from one side and convert to a wave data, then to the binary code consequently on the receiver side. Later, the generated code will hide inside an image before reaching the destination. The final step is to reverse the whole security process that has been done in the source side. Therefore it can provide a safe environment for voice communication among the internet client.

Drubbing an Audio Messages inside a Digital Image Using (ELSB) Method
It is mainly focused today to transfer the messages secretly between two communication parties. The message from the sender to receiver should be kept secret so that the information should not known by anyone. Secret is the important thing today. The technique that is used for secure communication is called as steganography and it means that to hide secret information into innocent data. Digital images are ideal for hiding secret information. An image containing a secret message is called a cover image. In this paper will discuss about secret transformation of audio messages. The audio messages are hidden inside a cover image so no one can hack the audio but the audio should be encrypted before hidden inside the image

The document discusses applying data hiding in audio-video files using anti-forensics techniques for authentication and data security. It proposes using steganography, which is hiding secret information in carrier files like audio and video, combined with anti-forensics techniques. The system would hide encrypted data in the least significant bits of frames in audio-video files. Parameters like PSNR and histograms would be analyzed at the transmitter and receiver ends to authenticate the data and ensure security. Common steganography algorithms like LSB and AES encryption would be used. The system aims to provide a more secure way of transferring data between client and server compared to traditional passwords or encryption alone.
Steganography Technique of Sending Random Passwords on Receiver’s Mobile (A N...
Abstract: Steganography is the art of hiding the fact that communication is taking place, by hiding information
in other information. There are many application of Steganography with different carrier file format. Here we
perform Steganography Technique with sending OTP on receiver mobile, which is one of the best secured
technique in current scenario. This technique is hiding file information into image with OTP password that is
only known by receiver. And can decrypt using that OTP only this is pure Steganography. Pure Steganography
means that there is none prior information shared by two communication parties. We are not sharing OTP
information by two communication parties. So this is more secure than other technique.
Key Words : Steganography, OTP, ICT, Password, IP, UDP, SIHS, LSB.
Steganography and watermarking
This document provides an overview of steganography and watermarking techniques for hiding information in digital media. It defines steganography as "covered writing" involving hiding secret messages within other digital files like images, audio, or video. Common steganography methods embed data in the least significant bits of pixels or audio samples. Watermarking differs in embedding identifying marks that are robust to modifications and aim to protect copyrights. The document outlines various media and techniques for each, applications, advantages and limitations of both steganography and watermarking.
Steganography flooding
Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. The goal is to hide messages in such a way that no one apart from the intended recipient knows about the message. Various media can be used for steganography including text, images, audio, and digital watermarking. Modern techniques allow hidden data to be embedded into files like images and audio in ways that are almost impossible to detect without the correct software and password. Steganography is commonly used by terrorists and criminals to covertly plan activities and share instructions.

This document discusses steganography, which is hiding secret messages within other carrier files such as text, images, audio, and video so that the message is concealed from those unaware of its existence. It defines steganography and its types based on carrier medium. Existing audio and video steganography systems are described along with their disadvantages like limited message length and lack of good interfaces. The proposed system aims to make information hiding simpler and more user-friendly using least significant bit modification for audio and video files, providing better security than existing systems. Sample outputs of selecting files for text-audio and text-video steganography are shown.

Drubbing an Audio Messages inside a Digital Image Using (ELSB) Method
It is mainly focused today to transfer the messages secretly between two communication parties. The message from the sender to receiver should be kept secret so that the information should not known by anyone. Secret is the important thing today. The technique that is used for secure communication is called as steganography and it means that to hide secret information into innocent data. Digital images are ideal for hiding secret information. An image containing a secret message is called a cover image. In this paper will discuss about secret transformation of audio messages. The audio messages are hidden inside a cover image so no one can hack the audio but the audio should be encrypted before hidden inside the image

The document discusses applying data hiding in audio-video files using anti-forensics techniques for authentication and data security. It proposes using steganography, which is hiding secret information in carrier files like audio and video, combined with anti-forensics techniques. The system would hide encrypted data in the least significant bits of frames in audio-video files. Parameters like PSNR and histograms would be analyzed at the transmitter and receiver ends to authenticate the data and ensure security. Common steganography algorithms like LSB and AES encryption would be used. The system aims to provide a more secure way of transferring data between client and server compared to traditional passwords or encryption alone.

Abstract: Steganography is the art of hiding the fact that communication is taking place, by hiding information
in other information. There are many application of Steganography with different carrier file format. Here we
perform Steganography Technique with sending OTP on receiver mobile, which is one of the best secured
technique in current scenario. This technique is hiding file information into image with OTP password that is
only known by receiver. And can decrypt using that OTP only this is pure Steganography. Pure Steganography
means that there is none prior information shared by two communication parties. We are not sharing OTP
information by two communication parties. So this is more secure than other technique.
Key Words : Steganography, OTP, ICT, Password, IP, UDP, SIHS, LSB.
Steganography and watermarking
This document provides an overview of steganography and watermarking techniques for hiding information in digital media. It defines steganography as "covered writing" involving hiding secret messages within other digital files like images, audio, or video. Common steganography methods embed data in the least significant bits of pixels or audio samples. Watermarking differs in embedding identifying marks that are robust to modifications and aim to protect copyrights. The document outlines various media and techniques for each, applications, advantages and limitations of both steganography and watermarking.
Steganography flooding
Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. The goal is to hide messages in such a way that no one apart from the intended recipient knows about the message. Various media can be used for steganography including text, images, audio, and digital watermarking. Modern techniques allow hidden data to be embedded into files like images and audio in ways that are almost impossible to detect without the correct software and password. Steganography is commonly used by terrorists and criminals to covertly plan activities and share instructions.
dokumen.tips_video-steganography-ppt.pptx
This document discusses steganography, which is hiding secret messages within other carrier files such as text, images, audio, and video so that the message is concealed from those unaware of its existence. It defines steganography and its types based on carrier medium. Existing audio and video steganography systems are described along with their disadvantages like limited message length and lack of good interfaces. The proposed system aims to make information hiding simpler and more user-friendly using least significant bit modification for audio and video files, providing better security than existing systems. Sample outputs of selecting files for text-audio and text-video steganography are shown.

Gas agency management system project report.pdf
The project entitled "Gas Agency" is done to make the manual process easier by making it a computerized system for billing and maintaining stock. The Gas Agencies get the order request through phone calls or by personal from their customers and deliver the gas cylinders to their address based on their demand and previous delivery date. This process is made computerized and the customer's name, address and stock details are stored in a database. Based on this the billing for a customer is made simple and easier, since a customer order for gas can be accepted only after completing a certain period from the previous delivery. This can be calculated and billed easily through this. There are two types of delivery like domestic purpose use delivery and commercial purpose use delivery. The bill rate and capacity differs for both. This can be easily maintained and charged accordingly.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. 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.

The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.
