The research presented focuses on cryptographic-agility for End-to-End Encryption systems (E2EE) that could be implemented for telemetry data *** recent report 1 by Microsoft after a security incident, describes the consequences that lead to encryption key leakage from telemetry data of highly protected production system. Internet of Things (IoT) and mobile devices constantly produce telemetry data which contains sensitive information. The data partially belongs to vendor, but IoT consumer's consent is needed to access such data for troubleshooting or forensic analysis. Goyal et al [2] proposed Attribute Based Encryption (ABE) as a solution for legitimately access the audit log contents by engineering team.

This paper proposes a novel demo application named CityScouter that utilizes multimodal data to analyze various aspects of urban characteristics quantitatively. Existing studies have proposed systems to examine either the physical characteristics of cities or the nature of people residing there. However, there is a lack of systems that analyze the characteristics of cities from both the physical and the residents' aspects. CityScouter addresses this challenge by leveraging computer vision technologies to quantify the quality of the urban landscape atmosphere and combining it with location information and user search history to reveal the desires of people visiting the area. The application is user-friendly and compatible with mobile devices, enabling users to conveniently enhance their understanding of cities while exploring them. Additionally, we provide reviews from urban development experts, offering insights into the applicability of our application. Furthermore, we showcase the usefulness and user experience of CityScouter through live demonstrations at the conference venue.

This paper presents the approach and results of Team Bun-Bo for the Sussex-Huawei Locomotion-Transportation (SHL) recognition challenge focusing on human activity detection. The objective of the challenge is to classify 8 modes of transportation-standing still, walking, running, biking, car, bus, train, and subway-using data collected from Inertial measurement Units (IMUs). Our approach involved extensive feature extraction from raw and processed kinematic indices, including acceleration, gyroscope, and magnetic data. Specific features included total acceleration across 3 axes and the horizontal plane, angles between different sensor axes, and successive differences of kinematic indices. We applied three ensemble boosting models under varying training and validation scenarios. Our findings highlight the Extreme Gradient Boosting Classifier (XGB), which achieved superior performance with an accuracy of 92% and an F1-score of 93%, outperforming other classifiers by margins ranging from 5% to 15%. This study underscores the effectiveness of advanced feature extraction techniques and ensemble learning models in enhancing the accuracy of transportation mode recognition systems based on IMU data.

This paper considers decentralized systems of multiple agents that interact in order to perform distributed computing or efficient information transfer in variant, constrained environments. These systems appear in various relevant use cases, including reliable multicast distribution, or dynamic resource allocation in systems in the Internet edge (datacenters, IOT deployments). This paper introduces an abstract, mathematical model, that allows to study analytically the behavior of these systems, as a set of interacting requesters and providers. The paper describes system orbits, and concentrates on the study of single-orbit systems. Ergodicity of system behavior in the single-orbit case is proved, and a full description of the stationary system behavior is derived. Closed expressions of the stationary distribution of requester decisions are provided. Analytical results are validated through extensive simulations. These single-orbit results are a necessary step for the analysis and further optimization of dynamic performance of these systems.

Nowadays, several software systems rely on stream processing architectures to deliver scalable performance and handle large volumes of data in near real-time. Stream processing frameworks facilitate scalable computing by distributing the application's execution across multiple machines. Despite performance being extensively studied, the measurement of fault tolerance-a key feature offered by stream processing frameworks-has still not been measured properly with updated and comprehensive testbeds. Moreover, the impact that fault recovery can have on performance is mostly ignored. This paper provides a comprehensive analysis of fault recovery performance, stability, and recovery time in a cloud-native environment with modern open-source frameworks, namely Flink, Kafka Streams, and Spark Structured Streaming. Our benchmarking analysis is inspired by chaos engineering to inject failures. Generally, our results indicate that much has changed compared to previous studies on fault recovery in distributed stream processing. In particular, the results indicate that Flink is the most stable and has one of the best fault recovery. Moreover, Kafka Streams shows performance instabilities after failures, which is due to its current rebalancing strategy that can be suboptimal in terms of load balancing. Spark Structured Streaming shows suitable fault recovery performance and stability, but with higher event latency. Our study intends to (i) help industry practitioners in choosing the most suitable stream processing framework for efficient and reliable executions of data-intensive applications;(ii) support researchers in applying and extending our research method as well as our benchmark;(iii) identify, prevent, and assist in solving potential issues in production deployments.

Urinary incontinence (UI) is a prevalent condition affecting millions of individuals worldwide, leading to various physical, social, and psychological challenges that diminish their quality of life. Current management approaches primarily focus on containment rather than proactive monitoring and warning systems. This paper presents the development and evaluation of a novel wearable technology called Privee, designed as an unobtrusive undergarment to monitor bladder fullness in real-time. Privee utilizes e-textile-based bioimpedance spectroscopy technology, which noninvasively assesses bladder fullness by analyzing the electrical properties of body tissues and fluids. The undergarment incorporates eight embroidered electrodes and textile transmission lines seamlessly integrated into the fabric. By continuously monitoring the bioimpedance signals from the bladder, Privee provides real-time information about the bladder's fullness level. This data is processed using a specialized algorithm to estimate the need for urination. The noninvasive nature of Privee eliminates the discomfort and risks associated with invasive monitoring methods, offering a user-friendly and convenient solution for individuals with UI, overactive bladder, or post-operative care needs. This innovative technology has the potential to improve patients' quality of life and optimize healthcare costs associated with UI management.
