Legal Liability for IOT Cybersecurity Vulnerabilities
Legal Liability for IOT Cybersecurity VulnerabilitiesPriyanka Aash There has been much discussion of "software liability," and whether new laws are needed to encourage or require safer software. My presentation will discuss how -- regardless of whether new laws are passed -- a tidal wave of litigation over defective IoT cybersecurity is just over the horizon.
The presentation will focus on a well-known example: Charlie Miller and Chris Valasek's 2015 Jeep hack. I'm lead counsel in the ongoing federal litigation over the cybersecurity defects Charlie and Chris exposed, and that are shared by 1.4 million Chrysler vehicles. As far as I know, our case is one of the first, and the biggest, that involves claims that consumers should be compensated for inadequate cybersecurity in IoT products.
This case is the tip of the iceberg. IOT products are ubiquitous, and in general their cybersecurity is feeble, at best. In the event of a cyberphysical IoT hack that causes injury, there are established legal doctrines that can be used to impose liability every company involved in the design, manufacturing, and distribution of an exploited IoT device or even its cyber-related components. Such liability could be crippling, if not fatal, for organizations that don't know how to properly handle and prepare for potential lawsuits.
Taking steps to minimize legal exposure before an accident happens or a lawsuit is filed—in the design, manufacture, product testing, and marketing phases of an IoT product—can be the difference between life and death for IoT companies. Knowing what steps to take and how to take them requires an understanding of the core legal principles that will be applied in determining whether a company is liable.
Research revealed on access control challenges for multinationals
Research revealed on access control challenges for multinationalsDoreen Loeber The document summarizes a benchmark research study conducted by Nedap on access control challenges faced by multinational companies. The study aimed to understand needs and challenges, allow benchmarking, and identify bottlenecks and future issues. Key topics included access infrastructure, systems/cards, convenience/security, costs, and future access control. Participants were from various European countries and industries. Feedback showed that company cards remain dominant, legacy technologies are still used, systems lack future-proofing, and undetected internal access is a bigger threat than remote hacking. The researchers concluded that while the world is changing rapidly, multinationals are struggling to modernize access control.

Seminar ppt fog compMahantesh Hiremath ABSTRACT
Cloud computing promises to significantly change the way we use computers and access and store our personal and business information. With these new computing and communications paradigms arise new data security challenges. Existing data protection mechanisms such as encryption have failed in preventing data theft attacks, especially those perpetrated by an insider to the cloud provider. For securing user data from such attacks a new paradigm called fog computing can be used. Fog Computing is a paradigm that extends Cloud computing and services to the edge of the network. Similar to Cloud, Fog provides data, compute, storage, and application services to end-users. The motivation of Fog computing lies in a series of real scenarios, such as Smart Grid, smart traffic lights in vehicular networks and software defined network .This technique can monitor the user activity to identify the legitimacy and prevent from any unauthorized user access. Here we have discussed this paradigm for preventing misuse of user data and securing information.

Internet of Things (IoT) - We Are at the Tip of An Iceberg
Internet of Things (IoT) - We Are at the Tip of An IcebergDr. Mazlan Abbas You are likely benefitting from The Internet of Things (IoT) today, whether or not you’re familiar with the term. If your phone automatically connects to your car radio, or if you have a smartwatch counting your steps, congratulations! You have adopted one small piece of a very large IoT pie, even if you haven't adopted the name yet.
IoT may sound like a business buzzword, but in reality, it’s a real technological revolution that will impact everything we do. It's the next IT Tsunami of new possibility that is destined to change the face of technology, as we know it. IoT is the interconnectivity between things using wireless communication technology (each with their own unique identifiers) to connect objects, locations, animals, or people to the Internet, thus allowing for the direct transmission of and seamless sharing of data.
IoT represents a massive wave of technical innovation. Highly valuable companies will be built and new ecosystems will emerge from bridging the offline world with the online into one gigantic new network. Our limited understanding of the possibilities hinders our ability to see future applications for any new technology. Mainstream adoption of desktop computers and the Internet didn’t take hold until they became affordable and usable. When that occurred, fantastic and creative new innovation ensued. We are on the cusp of that tipping point with the Internet of Things.
IoT matters because it will create new industries, new companies, new jobs, and new economic growth. It will transform existing segments of our economy: retail, farming, industrial, logistics, cities, and the environment. It will turn your smartphone into the command center for the both digital and physical objects in your life. You will live and work smarter, not harder – and what we are seeing now is only the tip of the iceberg.

IRJET- IoT based Door Access Control using Face RecognitionIRJET Journal This document summarizes an IOT based door access control system using face recognition. The system uses a Raspberry Pi connected to a Pi camera and PIR sensor. When motion is detected, the camera captures an image of the person's face. OpenCV's Haar classifier performs face detection and recognition by comparing the captured image to stored images. If a match is found, the door's servo motor is unlocked remotely through a GSM module. Otherwise, the image is emailed to authorized users who can allow or deny access. The system aims to improve security over traditional key/card based systems by automatically identifying individuals in real-time through facial recognition.
IRJET-Human Face Detection and Identification using Deep Metric Learning
IRJET-Human Face Detection and Identification using Deep Metric LearningIRJET Journal This document discusses a project that uses deep metric learning techniques for human face detection and identification in images and videos. Deep metric learning outputs a real-valued vector rather than a single classification. It uses libraries like OpenCV, Dlib, scikit-learn and Keras to build neural networks for facial recognition. The goals are to develop a system that can identify faces even from low quality images with variations in illumination, expression, angle and occlusions. Existing face recognition has challenges in these conditions, so the aim is to improve accuracy rates for normal and non-ideal images through deep metric learning approaches.
Face recognition 
Face recognition Chandan A V Face recognition is a biometric technique that uses unique facial measurements to identify or verify individuals in images. It analyzes the shape, pattern, and positioning of facial features. Face recognition systems first detect faces in images, then extract distinguishing nodal points like eye depth, nose width, and distance between eyes. They compare these measurements to templates stored in a database to identify matches. While convenient and non-invasive, face recognition has limitations like inability to distinguish identical twins and decreased accuracy with changes in appearance. It finds applications in security, law enforcement, and commercial uses like building access control and ATMs.

MBA SYSTEMS To study on Public Safety through Innovative Face Recognition Tec...suvidhakamble12 Is facial recognition technology too intrusive to individuals’ privacy?
The use of – what has been characterised as – intrusive and disruptive technologies are often justified by the overriding public interest, public safety and prevention of crime justifications. Law enforcement authorities can make use of different kinds of facial recognition technology in order to investigate crime but to detect and prevent it in the future. The use of live facial recognition in public spaces has been criticised as intrusive to people’s privacy, as it automatically collects biometric personal data of people walking, crossing the street, and going about their daily lives. It is note-worthy to mention that local authorities claim that the individual whose biometric personal data is being collected is aware of the data collection and purpose of processing. Whenever the police are investigating a crime and being aided by the use of live facial recognition, they are collecting real-time data of people passing by a specific area where a crime has taken place.

Strategies for Choosing eKYC Solutions.pdf
Strategies for Choosing eKYC Solutions.pdfKMSSolutionsMarketin eKYC solution is one of the core pillars of the Digital Banking model.
Now when most banks are relying on mobile apps to interact with
customers, an end-to-end eKYC solution is the more relevant venue to onboard customers than manual processing that is traditionally conducted at bank offices. Recent findings by J.D. Power study revealed that 31% of new account openings are done on a mobile banking app or bank’s websites, an increase of 22% compared to 2019. But in reality, banks seem not to do so well with eKYC since according to Signicat, 40% of customers surveyed have abandoned their online applications halfway. The reason is straightforward: a majority of banks find their eKYC Solutions unsuitable.
With a multitude of providers out there, each talks big about how
comprehensive their eKYC solution is, it can be hard to tell the good from the bad one.
This article will walk you through a number of key considerations when evaluating vendors for your eKYC solution. You will also find some tactics to question your bidders.

Could Virtual Threads cast away the usage of Kotlin Coroutines - DevoxxUK2025
Could Virtual Threads cast away the usage of Kotlin Coroutines - DevoxxUK2025João Esperancinha This is an updated version of the original presentation I did at the LJC in 2024 at the Couchbase offices. This version, tailored for DevoxxUK 2025, explores all of what the original one did, with some extras. How do Virtual Threads can potentially affect the development of resilient services? If you are implementing services in the JVM, odds are that you are using the Spring Framework. As the development of possibilities for the JVM continues, Spring is constantly evolving with it. This presentation was created to spark that discussion and makes us reflect about out available options so that we can do our best to make the best decisions going forward. As an extra, this presentation talks about connecting to databases with JPA or JDBC, what exactly plays in when working with Java Virtual Threads and where they are still limited, what happens with reactive services when using WebFlux alone or in combination with Java Virtual Threads and finally a quick run through Thread Pinning and why it might be irrelevant for the JDK24.
