Steganography
Steganography is a technique for hiding secret data within various file formats such as images, video, and audio. It can provide an extra layer of security beyond encryption alone by concealing the very existence of secret messages. Common steganography methods embed hidden text as small changes to pixel values in images or alterations to audio/video files imperceptible to human senses. The hidden data can be used to protect copyrighted materials or enable unauthorized access.
Steganography
Steganography is a technique for hiding secret data within other non-secret data. It can be used alongside cryptography to further enhance security. Steganography techniques can hide data in images, video, or audio files by making small changes that are imperceptible to human senses. The hidden data could be used to protect copyrighted materials or allow unauthorized viewing of content. Information hiding through steganography or other methods can conceal communicating parties' identities, the occurrence of communications, or the content of transmitted data from attackers at different stages of a crime or attack.
Steganography
Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. There are two main branches - steganography and watermarking. Steganography hides the existence of the message itself, while watermarking involves openly communicating the existence of a message to provide copyright protection. Throughout history, various techniques have been used to hide secret messages, from wax-covered wooden panels to microdots. Modern steganography uses algorithms and least significant bit insertion to hide data in images, audio, and other file types. Detection of hidden messages involves steganalysis to identify subtle statistical changes revealing concealed data.

How Encryption Works
Encryption is used to encode information so that only those with the key can decode it, providing security for computers and information sent over the internet. There are two main types of encryption - symmetric key encryption where both sides use the same key, requiring the key to be installed on both computers beforehand, and public key encryption which addresses issues with symmetric key using a two-key system that allows encryption and decryption with different keys. A 1976 paper introduced public key encryption as an improvement over symmetric key encryption.
What is cloud encryption
Businesses rely heavily on cloud technology but this creates vulnerabilities that malicious actors may exploit to access private information. Encryption is a fundamental element of cloud security that scrambles data so even if accessed by malicious parties, the information cannot be viewed. There are two main types of encryption: symmetric uses one key for encryption and decryption while asymmetric uses a public key to encrypt and a private key to decrypt, providing better security. Encryption should be used to protect data both when in transit between networks and when at rest in storage to provide comprehensive security and prevent attacks. While encryption is effective, its additional costs can lead businesses to underutilize it despite the higher costs of data breaches.

File encryption encrypts and decrypts files on hard drives and removable media. Data encryption hides information and is a branch of mathematics and computer science related to information theory and computer security. Link encryption encrypts and decrypts all traffic at each end of a communications line, unlike end-to-end encryption where encryption only occurs between the sender and receiver. A virtual private network (VPN) allows for secure communications through open connections in a larger network by tunneling the link-layer protocols, though it does not necessarily include authentication or content encryption.

Identifying XSS Vulnerabilities
Cross-site scripting (XSS) attacks are a type of injection where malicious scripts are injected into otherwise benign websites. There are three main types of XSS attacks: reflected XSS occurs when scripts are injected via URL parameters and executed when the page is loaded; stored XSS occurs when scripts are saved to a database and executed on page load; DOM-based XSS occurs when scripts modify the DOM environment and execute unexpectedly. XSS can be used to hijack sessions, perform phishing, keylogging, and CSRF attacks. Input validation, output encoding, and content security policies can help prevent XSS.

Offensive cyber security: Smashing the stack with Python
: A necessary step in writing secure code is having an understanding of how vulnerable code can be exploited. This step is critical because unless you see the software from the vantage point of a hacker, what may look to be safe and harmless code, can have multiple vulnerabilities that result in systems running that software getting p0wned. The goal of this tech talk is to provide a step-by-step illustration of how not adhering to secure software design principles such as properly bounds checking buffers can open up computing devices to exploitation. Specifically, we will show that by using a very easy to use scripting language like python, we can do the following: 1) Smash the stack of a system running vulnerable code to gain arbitrary access. 2) Install a key logger that can phone home to a command and control server.

Steganography
This document discusses steganography, which is the art and science of hiding messages within other harmless-looking carriers or covers. Some examples of historical steganography techniques include using wax tablets, tattoos, and invisible ink. Modern digital steganography can hide messages in text, images, audio, and video. Image steganography is particularly common, as it takes advantage of human's limited visual perception of colors. Steganography, combined with cryptography for encryption, provides a secure means of communication. However, steganography can also enable illegal or terrorist activities if abused. The field of steganalysis aims to detect hidden messages for security purposes.

A Steganography LSB technique for hiding Image within Image Using blowfish En...
Steganography refers to information or a file that has been hidden inside a digital image, video
or audio file. There are different carrier file formats can be used such as Text Steganography, Image
Steganography, Audio/Video Steganography, but Image Steganography are the most popular because of their
frequency on the Internet. It is the first common methods used for hiding the information in the cover image.
The Least Significant Bit (LSB) steganography is one such technique in which least significant bit of the image
is replaced with data bit. steganographic algorithm for 8bit (gray scale) or 24 bit (colour image) is presented in
this paper. Sometime steganography will not cover the total security of secret massage. So an additional security
need to the secret massage. For this purpose blowfish encryption Algorithm is used in the proposed
Steganographic system This work is concerned with implementing Steganography for images, with an
improvement security and image quality.
The experimental result shows that the stego-image is visually indistinguishable from the original cover-image
It comes under the assumption that if the feature is visible, the point of attack is evident, thus the goal here is
always to cover up the very existence of the embedded data. and that the algorithm has a high capacity and a
good invisibility.

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.

Cyber Security PowerPoint Templates.pptx
Steganography is the process of hiding secret information within a cover file such as an image, audio, or video file. The secret information is hidden in a way that is not visible to the human eye. There are different types of steganography including hiding messages in still images, audio files by embedding data in the layers of MP3 files or audio noise, and video files which provide more irrelevant bits to hide data. The steps involve dragging the carrier and secret files into a steganography tool, applying a passphrase, and revealing the hidden data by the receiver. Steganography has applications in confidential communication, protecting data integrity, and digital rights management.
LSB Based Image Steganography for Information Security System
Information hiding in a cover file is one of the most modernized and effective ways for transferring secret message from sender to receiver over the communication channel. There are many steganographic techniques for hiding secret message in image, text, audio, video and so on. Image Steganography is also one of the common methods used for hiding the information in the cover image. In this research work, the secret message is hidden in a cover image file using image steganography. LSB is very efficient algorithm used to embed the information in a cover file. The LSB based image steganography with various file sizes is analyzed and illustrated their results. Bitmap .bmp image is used as a cover image file to implement the proposed system. The detail Least Significant Bit LSB based image steganography is introduced. In this paper, the new embedding algorithm and extracting algorithm are presented. While embedding the secret message in a cover image file, the starting embedded pixel is chosen according to public shared key between sender and receiver. The original cover image and embedded image with secret message are analyzed with PSNR values and SNR values to achieve security. The resulting embedded image shows the acceptable PSNR and SNR values while comparing with the original cover image. The proposed system can help the information exchanging system over communication media.

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
HCL Notes und Domino Lizenzkostenreduzierung in der Welt von DLAU
Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-und-domino-lizenzkostenreduzierung-in-der-welt-von-dlau/
DLAU und die Lizenzen nach dem CCB- und CCX-Modell sind für viele in der HCL-Community seit letztem Jahr ein heißes Thema. Als Notes- oder Domino-Kunde haben Sie vielleicht mit unerwartet hohen Benutzerzahlen und Lizenzgebühren zu kämpfen. Sie fragen sich vielleicht, wie diese neue Art der Lizenzierung funktioniert und welchen Nutzen sie Ihnen bringt. Vor allem wollen Sie sicherlich Ihr Budget einhalten und Kosten sparen, wo immer möglich. Das verstehen wir und wir möchten Ihnen dabei helfen!
Wir erklären Ihnen, wie Sie häufige Konfigurationsprobleme lösen können, die dazu führen können, dass mehr Benutzer gezählt werden als nötig, und wie Sie überflüssige oder ungenutzte Konten identifizieren und entfernen können, um Geld zu sparen. Es gibt auch einige Ansätze, die zu unnötigen Ausgaben führen können, z. B. wenn ein Personendokument anstelle eines Mail-Ins für geteilte Mailboxen verwendet wird. Wir zeigen Ihnen solche Fälle und deren Lösungen. Und natürlich erklären wir Ihnen das neue Lizenzmodell.
Nehmen Sie an diesem Webinar teil, bei dem HCL-Ambassador Marc Thomas und Gastredner Franz Walder Ihnen diese neue Welt näherbringen. Es vermittelt Ihnen die Tools und das Know-how, um den Überblick zu bewahren. Sie werden in der Lage sein, Ihre Kosten durch eine optimierte Domino-Konfiguration zu reduzieren und auch in Zukunft gering zu halten.

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

- 2. Introduction Steganography Steganography comes from Greek Word. It means covered or secret writing. ” Steganography = steganos (covered) + graphein (writing) ” Main Points ” The goal of steganography is to hide messages in such a way that no one apart from the intended recipient even knows that a message has been sent.” This can be achieve by concealing the existence of information within seemingly harmless carriers or cover.
