This document proposes a method for preserving privacy in video surveillance by scrambling regions of interest (ROIs) in video sequences. It discusses scrambling quantized DCT or DWT coefficients in compressed video to conceal information in ROIs while maintaining understanding of the overall scene. The scrambling is flexible and reversible with a private key, has low computational complexity, and introduces minimal impact on video coding performance. Previous approaches are also summarized.
Digital images can originate from scanners, digital cameras, or be computer-generated. There are two main categories of digital image formats: raster (bitmap) images which use a grid of pixels and are resolution dependent, and vector images which use mathematical formulas to describe shapes and are resolution independent. Digital cameras capture light as electronic signals from image sensors, then convert this through analog-to-digital conversion into digital images stored as files.

Difference between Interlaced & progressive scanningaibad ahmed
The document discusses the differences between interlaced scanning and progressive scanning techniques for displaying video images. Interlaced scanning, which was developed for CRT monitors, divides image frames into odd and even lines that are refreshed alternately, resulting in some distortion or jaggedness when viewing moving images. Progressive scanning, as used in computer monitors and digital cameras, scans each line sequentially without interlacing, resulting in a smoother image with less flicker suitable for viewing fine details in moving images. The effects of interlacing can be reduced through de-interlacing techniques, though a progressive scan is better able to clearly capture and display details in moving objects.

It describes differences between progressive and interlaced scanning as well as technical details of ATSC standards for HDTV.
Computer graphics involves drawing pictures on screens through programming and manipulating data. The primary output device is a video monitor, which uses a cathode ray tube. In a raster scan display, an electron beam sweeps across the screen line by line to display pixels stored in a refresh buffer. This avoids screen flicker. A random scan display directs the electron beam only where needed for high resolution line drawings, but is limited to simple images. Raster graphics systems use a video controller to access a frame buffer in memory and refresh the screen.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

Interlaced scanning
• TV uses interlaced
scanning
• Each picture, referred
to as a frame, is
divided into two
separate sub-pictures,
referred to as fields.
Two fields, odd and
even, make up a frame.

Progressive Scanning
• Used in delivering
computer signals.
• Picture is painted on
the screen by scanning
all of the horizontal
lines of the picture in
one pass from the top
to the bottom.

NTSC and PAL YUV Color Model
• NTSC • YUV model defines a
– Less flicker color space in terms of
one luminance
– Poorer resolution
(brightness) and two
• PAL chrominance (color)
– Sharper resolution components.
– More flicker • Models human color
reception better than
RGB.
