Die 10. Jahrestagung des Förderkreises Rückversicherung fand am 7. Juli 2017 in Niederkassel bei Köln statt. Etwa 80 Repräsentanten der in dem Förderkreis mitwirkenden (Rück-) Versicherungsunternehmen sowie eingeladene Gäste nahmen daran teil. Im Rahmen der Jahrestagung wurde zum dritten Mal der Researchers‘ Corner durchgeführt, in dessen Verlauf neun der in der Kölner Forschungsstelle Rückversicherung beschäftigten Wissenschaftlichen Mitarbeiter je einen Kurzvortrag zu dem individuellen Forschungsprojekt hielten. Des Weiteren führte von Prof. Materne Interviews mit den Herren Lorenz Kielwein und Frank Baumann. Kielwein berichtete über die Anwendung der mathematischen Systemtheorie auf Change Management Prozesse und Baumann aus der Erfahrung seiner 30-jährigen Tätigkeit bei der Gothaer. In drei Sessions wurden jeweils parallel drei Kurzvorträge mit Poster gehalten und im Anschluss diskutiert. Die Heterogenität der vorgetragenen Themenschwerpunkte der Mitarbeiter spiegelt die Verzahnung der Forschungstheorie mit der Praxistätigkeit wider. In den Sessions haben folgende Vortragende in deutscher und englischer Sprache gesprochen:
Runde 1
a) Fabian Pütz (M.Sc.)
Alternative Capital und Basisrisiko in der Standardformel (non-life) von Solvency II

The 11th Annual Meeting of the Sponsoring Group Reinsurance (Förderkreis
Rückversicherung) on the topic of reinsurance was held 13 July 2018, in
Niederkassel near Cologne. Some 85 invited representatives of the (re)insurance
companies supporting the Sponsoring Group took part in the meeting, together with
guests. Offered for the fourth time as part of the Annual Meeting, the Researchers’
Corner gave eight members of academic staff at the Cologne Research Centre for
Reinsurance an opportunity to deliver a presentation on their respective individual
research projects.
Professor Materne also conducted interviews with Dr. Falk Niehörster (Climate Risk
Innovations) and Dr. Magnus Kobel (YAS.life). Dr. Niehörster reported on his
research and consulting activities in regard to maritime climate change and Dr. Kobel
on the business model of his InsurTec, YAS.life, and his general experience in the
establishment and development of start-ups.
In three sessions – each with 2-3 parallel lectures with posters – the most important
results of the scientific studies by the Cologne Research Centre for Reinsurance were
presented and discussed. The heterogeneity of the topics presented by academic
staff reflects the dovetailing of research theory with practice.
Worldwide there is a big need for affordable livingspace. Globalization leads to a connection of development and ideas in the field of building. Open Source communities could improve and accelerate this development. The potential of theses communities lies in the connection of different diciplines. Especially for building projects with a small budget and a willingness to participate in the work process open source do-it-yourself constructions are a great opportunity to help cover the need of affordable work and living space. Renewable materials such as wood offer great potential here. New, standardised technologies make a decentralised production possible.
The 10th Annual Meeting of the Sponsoring Group Reinsurance was held 7 July 2017, in Niederkassel
near Köln. Some 80 representatives of the (re)insurance companies involved in the Sponsoring Group took part in the meeting, together with invited guests. Offered for the third time as part of the Annual Meeting, the Researchers’ Corner gave nine members of academic staff at the Cologne Research Centre for Reinsurance an opportunity to deliver short presentations on their individual research projects. Professor Materne also conducted interviews with Messrs Lorenz Kielwein and
Frank Baumann. Kielwein reported on the application of mathematical systems theory to processes in change management, and Baumann on his 30 years of experience at Gothaer. During each of three sessions, three short lectures with posters were held in parallel and discussed afterwards. The heterogeneity of the topics presented by the staff members reflects the dovetailing
of research theory with practice.
In the sessions, the following speakers presented in German and English:
Round 1
a) Fabian Pütz (M.Sc.)
Alternative Capital and Basic Risk in the Standard Formula (Non-Life) of Solvency II
b) Manuel Dietmann (M.Sc.)
SFCR: Findings for Initial Publication
c) Jan Böggemann (B.Sc.)
Optimising the Purchase of Optional Reinsurance by an Industrial Insurer

a brief lecture.

Public-Private Partnership in Emerging and Developing Countries.
We would like to thank the funding bodies who make this event possible to begin with and provide our scholars an opportunity to conduct their research.
Risk-based authentication (RBA) is an adaptive security measure to strengthen password-based authentication. RBA monitors additional implicit features during password entry such as device or geolocation information, and requests additional authentication factors if a certain risk level is detected. RBA is recommended by the NIST digital identity guidelines, is used by several large online services, and offers protection against security risks such as password database leaks, credential stuffing, insecure passwords and large-scale guessing attacks. Despite its relevance, the procedures used by RBA-instrumented online services are currently not disclosed. Consequently, there is little scientific research about RBA, slowing down progress and deeper understanding, making it harder for end users to understand the security provided by the services they use and trust, and hindering the widespread adoption of RBA.
In this paper, with a series of studies on eight popular online services, we (i) analyze which features and combinations/classifiers are used and are useful in practical instances, (ii) develop a framework and a methodology to measure RBA in the wild, and (iii) survey and discuss the differences in the user interface for RBA. Following this, our work provides a first deeper understanding of practical RBA deployments and helps fostering further research in this direction.
Online services such as social networks, online shops, and search engines deliver different content to users depending on their location, browsing history, or client device. Since these services have a major influence on opinion forming, understanding their behavior from a social science perspective is of greatest importance. In addition, technical aspects of services such as security or privacy are becoming more and more relevant for users, providers, and researchers. Due to the lack of essential data sets, automatic black box testing of online services is currently the only way for researchers to investigate these services in a methodical and reproducible manner. However, automatic black box testing of online services is difficult since many of them try to detect and block automated requests to prevent bots from accessing them.
In this paper, we introduce a testing tool that allows researchers to create and automatically run experiments for exploratory studies of online services. The testing tool performs programmed user interactions in such a manner that it can hardly be distinguished from a human user. To evaluate our tool, we conducted - among other things - a large-scale research study on Risk-based Authentication (RBA), which required human-like behavior from the client. We were able to circumvent the bot detection of the investigated online services with the experiments. As this demonstrates the potential of the presented testing tool, it remains to the responsibility of its users to balance the conflicting interests between researchers and service providers as well as to check whether their research programs remain undetected.
The 12th Annual Meeting of the Sponsoring Group Reinsurance [Förderkreis Rückversicherung] was held 5th July 2019 in Niederkassel, near Cologne. Some 80
representatives of the (re)insurance companies involved in the Sponsoring Group took part in the meeting, along with guests. Offered for the fifth time as part of the
Annual Meeting, the Researchers’ Corner gave eight members of academic staff at the Cologne Research Centre for Reinsurance an opportunity to deliver a presentation on their respective current research projects. In three sessions – each featuring 2-3 parallel lectures with posters – the most important results of the scientific studies by the Cologne Research Centre for Reinsurance were presented and discussed. The heterogeneity of the topics presented by academic staff reflects the dovetailing of Cologne Research Centre with reinsurance practice.
