In this work we are describing our preliminary experimental evaluation of open-source machine learning based pose estimation solutions for tracking a surfer’s skeleton on a stationary wave. We are briefly describing the sport’s environment and development and the current state-of-the-art of machine learning based single camera 2D and 3D pose estimation solutions. The main part of the paper deals with the experiment’s setup and the interpretation of the resulting data of the movements of one surfer. We are closing with our lessons learned and our next steps.

Live-Shopping mit Virtual Beings

Im Zuge der Covid-Pandemie hat sich insbesondere in China der Trend des “live-eCommerce“ verstärkt, der dort im Jahr 2022 auf ein Volumen von 43,2 Milliarden Yuan geschätzt wird (etwa €6Mrd.) Dieser lässt sich in etwa als „digitales Teleshopping“ umschreiben und umfasst oft eine intensive Interaktion mit dem Publikum. Zuschauer können „live“ Fragen zu präsentierten Produkten stellen. Grundsätzlich lässt sich dies auch in den virtuellen Welten realisieren, wie zum Beispiel der chinesische Handelsriese AliBaba mit seinem Ansatz auf der Plattform TaoBao zeigt. Dort entstehen eigene dreidimensionale virtuelle Shopping-Umgebungen, die per Avatar besuchbar und „erlebbar“ sind. Die einzelnen Verkaufsabteilungen und Geschäfte sind mit – virtualisierten – Mitarbeitern besetzt, welche die Kunden in „Echtzeit“ beraten. Zu festen Terminen sollen zudem – analog zu dem bereits praktizierten „gewöhnlichen“ online-Live-Shopping – interaktive Verkaufsveranstaltungen und Produktpräsentation stattfinden.

Smartphones in a Microwave: Formal and Experimental Feasibility Study on Fingerprinting the Corona-Warn-App

Contact Tracing Apps (CTAs) have been developed to contain the coronavirus disease 19 ( COVID-19) spread. By design, such apps invade their users’ privacy by recording data about their health, contacts, and—partially—location. Many CTAs frequently broadcast pseudorandom numbers via Bluetooth to detect contacts. These numbers are changed regularly to prevent individual smartphones from being tracked trivially. However, we find that this technology
is vulnerable to fingerprinting techniques. We measured real smartphones and observed that the Corona-Warn-App (CWA ) exhibits a device-specific latency between two subsequent broadcasts. These timing differences provide a potential attack vector for fingerprinting smartphones by passively recording Bluetooth messages. This could conceivably lead to the tracking of users’ trajectories and, ultimately, the re-identification of users.

Sustainability, the Circular Economy and Digitalisation in the German Textile and Clothing Industry

The textile and clothing (T&C) industry is not usually viewed as an exemplar of sustainable development and the circular economy (CE), as the industry has hitherto developed its products in a linear fashion, with relatively little recycling of the finished goods. This article examines the industry’s approach to the core sustainability concept and the CE in particular through a review of the available academic literature, evidence from corporate sustainability reports and websites, and feedback from an online survey of industry professionals. More specifically, the article investigates how German T&C companies are addressing sustainability in their corporate strategies and what activities relating to the CE are being pursued in the industry. The role of digital technologies in the transition to sustainability and the CE in the German T&C industry is also explored. The study finds that whilst sustainability is now firmly embedded at the strategic level in the vast majority of the companies studied, attitudes towards the CE are mixed. The use of digital technologies in support of sustainability objectives is also limited at present, but the need to meet compliance requirements and new customer perceptions of sustainability will speed the transition to CE activities, which will be facilitated by the greater exploitation of these technologies. An operational framework for initiating such a transition is developed, and action lists in the key areas of change organization, products, and processes are presented. These may be used as a guideline for practitioners, and the findings also make a small contribution to the scarcity of literature in this field of research.

Reverse-Engineering Bank Addressing Functions on AMD CPUs

Heckel, Martin; Adamsky, Florian (2023)

The 3rd Workshop on DRAM Security (DRAMSec 2023), co-located with ISCA 2023.


Open Access Peer Reviewed
 

The memory controller of the CPU uses bank addressing functions to determine physical locations within DRAM DIMMs. There are many fields of application for these addressing functions, particularly in security. For exam- ple, many Rowhammer proofs-of-concept use bank addressing functions to select addresses located on the same bank but in different rows to produce row conflicts. AMD provides these addressing functions for older CPU models. Hence, research on reverse-engineering addressing functions mainly targeted Intel CPUs since Intel did not publish these functions. However, AMD stopped to publish the DRAM addressing functions several years ago. AMD manufactures roughly a third of the sold CPUs in today’s CPU market. We analyze reverse- engineering tools for addressing functions and find that they do not work with AMD CPUs, hindering reverse-engineering at- tempts and Rowhammer attacks on systems with AMD CPUs. In this paper, we introduce an approach to reverse-engineer the addressing functions of AMD CPUs, which facilitates future Rowhammer experiments on AMD CPUs.
