Investigative Interviews using a Multimodal Virtual Avatar

Investigative Interviews using a Multimodal Virtual Avatar
To meet best-practice standards, we are developing an interactive virtual avatar aiming as a training tool to raise interviewing skills of child-welfare and law-enforcement professionals. Therefore, we present the “Ilma” avatar that recognizes interviewers’ behavior during open-ended, closed and leading questions, and which can automatically respond to the conversation. We conducted a user study in which master students (N=3) and child protective workers (N=8) interviewed “Ilma” and rated their perception of the interaction. The results show that the participants valued the interaction and found the avatar useful. Thus, it has great potential to be an effective training tool.

Detecting Physical Impacts by Monitoring State of Polarisation in a Live Fibre-To-The-Home Data-Communication Air-Cable
Heavy wind may tear cables down, damaging infrastructure, triggering outage in data-communication networks. We demonstrate local observations of wind in the access-network, monitoring State of Polarisation in a live Fiber-To-The-Home air-cable.

Designing and Testing a Mobile App to Fight Child, Early, and Forced Marriage in Developing Countries
Child marriage is still a severe issue in developing countries. Among the strategies that work most to fight it, is empowering girls with information combined with the education of parents and community. As smartphones are more accessible year after year in developing countries, we want to investigate how a mobile app could effectively fight child marriage and which characteristics such an app should have. The research was organized into three main phases. The first phase was focused on 4 expert semi-structured interviews to understand if an app could be a good solution to help in fighting child marriage. The second and third phases were based on a case study with young girls in the Democratic Republic of the Congo. The second phase had focus groups with 26 girls to test and improve the requi- sites of the app, and the third phase had a questionnaire that 14 girls had to fill out after trying the app. The study shows that girls in developing countries have access to smartphones, and most can use the developed app satisfactorily and that it is worth continuing to study this problem as an app could be a new instrument to use alongside traditional tools.

A Live Demonstration of HiPerConTracer 2.0
In Proceedings of the 31st International Conference on Software, Telecommunications and Computer Networks (SoftCOM). Split/Croatia, 2023.Status: Accepted
A Live Demonstration of HiPerConTracer 2.0
HiPerConTracer is an open source tool for large-scale, long-term, high-frequency Ping and Traceroute measurements. Using such measurements, it is possible to obtain information about latency in the network, as well as about the actual routing. This proposed live demo provides an overview over the tool and its features, as well as an introduction of how to use it for performing measurements, storing the results, querying selected results, and post-processing them for visualisation.

How Large Is the Gap? Exploring MANRS and ISO27001 Security Management

How Large Is the Gap? Exploring MANRS and ISO27001 Security Management
Ensuring security of network traffic between op- erators is very important. This paper aims to enhance un- derstanding of the relationship between two crucial internet security standards, namely, Mutual Agreed Norms for Rout- ing Security (MANRS) and ISO/IEC 27001 (ISO27001). By examining the correlation between MANRS participation and ISO27001 certification, this study provides insightful analysis. To validate compliance, data from diverse sources such as CAIDA, PeeringDB, and RPKI is correlated. We assess ISO27001 controls that bear relevance to MANRS compliance and illustrate how implementing either framework leads to a reduced risk of security breaches. Moreover, a cost analysis reveals that the simultaneous implementation of MANRS and ISO27001 does not significantly increase costs or complexity.

Towards a Lightweight Task Scheduling Framework for Cloud and Edge Platform

Towards a Lightweight Task Scheduling Framework for Cloud and Edge Platform
Mobile devices are becoming ubiquitous in our daily lives, but they have limited computational capacity. Thanks to the advancement in the network infrastructure, task offloading from resource-constrained devices to the near edge and the cloud becomes possible and advantageous. Complete task offloading is now possible to almost limitless computing resources of public cloud platforms. Generally, the edge computing resources support latency-sensitive applications with limited computing resources, while the cloud supports latency-tolerant applications. This paper proposes one lightweight task-scheduling framework from cloud service provider perspective, for applications using both cloud and edge platforms. Here, the challenge is using edge and cloud resources efficiently when necessary. Such decisions have to be made quickly, with a small management overhead. Our framework aims at solving two research questions. They are: i) How to distribute tasks to the edge resource pools and multi-clouds? ii) How to manage these resource pools effectively with low overheads? To answer these two questions, we examine the performance of our proposed framework based on Reliable Server Pooling (RSerPool). We have shown via simulations that RSerPool, with the correct usage and configuration of pool member selection policies, can accomplish the cloud/edge setup resource selection task with a small overhead.

Live Streaming Technology and Online Child Sexual Exploitation and Abuse - A Scoping Review
Trauma, Violence, & Abuse (2023).Status: Accepted
Live Streaming Technology and Online Child Sexual Exploitation and Abuse - A Scoping Review
Livestreaming of child sexual abuse is an established form of online child sexual exploitation
and abuse. However, only a limited body of research has examined this issue. The Covid-19
pandemic has accelerated internet use and user knowledge of livestreaming services
emphasising the importance of understanding this crime. In this scoping review, existing
literature was brought together through an iterative search of eight databases containing peer-
reviewed journal articles, as well as grey literature. Records were eligible for inclusion if the
primary focus was on livestream technology and online child sexual exploitation and abuse,
the child being defined as eighteen years or younger. Fourteen of the 2,218 records were
selected. The data were charted and divided into four categories: victims, offenders,
legislation, and technology. Limited research, differences in terminology, study design, and
population inclusion criteria present a challenge to drawing general conclusions on the
current state of livestreaming of child sexual abuse. The records show that victims are
predominantly female. The average livestream offender was found to be older than the
average online child sexual abuse offender. Therefore, it is unclear whether the findings are
representative of the global population of livestream offenders. Furthermore, there appears to
be a gap in what the records show on platforms and payment services used and current digital
trends. The lack of a legal definition and privacy considerations pose a challenge to
investigation, detection, and prosecution. The available data allow some insights into a
potentially much larger issue.
