abstract = {All indoor positioning approaches face the challenge to deal with errorneous input data from sensors. Especially independent systems like dead reckoning rely highly on high quality input data from accelerometers and gyroscopes for an accurate prediction of the user's position. But with the widespread of cheaper devices with low quality sensors, the obtained input data is noisy and of poor quality. Since errors accumulate within a pedestrian dead reckoning system, there is an inevitable need for recalibration on a regular basis. We propose a pedestrian dead reckoning system based on state of the art particle filters, which is recalibrated using anchor points and uses a pedestrian particle movement model. Our evaluation includes comparisons with a standard particle filter as well as a backtracking particle filter that includes information from indoor maps. We show that a combination of anchor point recalibration, error calculation of sensor bias and a fine-tuned particle movement model can decrease the RMSE be 0.77 m.}

  abstract={Bitcoin has become increasingly important for several years. While being declared dead in the meantime, it got a boost in 2011. The exchange rate increased from  in January 2013 up to 0 in April 2013 and even 0 in early 2014. Lots of existing work addresses the analysis of the publicly available transaction graph. There are evaluations of the user's anonymity and privacy, but no proper measurements of the underlying network. In this paper, we present novel insights about Bitcoin's peer-to-peer network, with a focus on its distribution among distinct autonomous systems. The resilience of the Bitcoin ecosystem, the unambiguousness of the blockchain in use, the propagation and verification of transaction blocks, but also the anonymity of Bitcoin's users depend on the structure of the global peer-to-peer network. Our work is the first thorough analysis of Bitcoin's underlying peer-to-peer network, especially with regard to its distribution at the autonomous system level. We traversed Bitcoin's peer-to-peer network in a protocol-compliant manner and made statements about the size of the accessible network and the number of clients. This information is useful when modelling the probability of attacks against the user's privacy or other aspects. Further, we investigated the distribution of the peer-to-peer network on autonomous systems. The concrete form has an impact on the above-mentioned topics, such as vitality, resilience or privacy. Finally, we analysed the mechanism to announce known peers. It turns out that Bitcoin's peer announcement is not well distributed, affecting information propagation.},

In der vorliegenden Arbeit wird gezeigt, wie Kontexte durch Bloom-Filter beschrieben werden können. Das ermöglicht eine generische Vergleichsoperation, mit der die Ähnlichkeit von Kontexten über bekannte Maße für Mengenähnlichkeiten ausgedrückt werden kann. Darauf aufbauend wird die kontextzentrische Adressierung für verteilte Systeme definiert.
Weitreichende Implikationen ergeben sich dadurch für die Kommunikation von Nutzern in Online Sozialen Netzen, wenn deren Profile nur innerhalb ähnlicher Kontexte verknüpft werden. Dann kann das Problem sich überschneidender Öffentlichkeiten verhindert und so eine authentischere Kommunikation ermöglicht werden. }

However, alternative routes have only been introduced recently for the indoor space due to the complexity of these environments. Furthermore, the number of alternative routes in buildings can be quite high. With this paper, we propose to organize sets of alternative routes by employing archetypal analysis on a feature space representation of routes and show results in which a set of hundreds of routes between the same start and end point has been compressed to only a few obviously different archetypal routes. Additionally, the framework allows for comparing routes with archetypes and with each other. This comparison does not reveal spatial similarity alone, but rather a measure of routes' similarity representing their inherent semantic character.}

Technological constraints offer great protection of listeners' privacy but prevent radio stations from implementing modern business models like personalization and mining valueable user information, at the same time. This paper describes a fully distributed system that aims at overcoming current technological constraints in interconnecting radio stations and their listeners while retaining a comparable protection of sensitive user data. Namely, a peer-to-peer architecture with integrated data-mining-capabilities employing differential privacy is proposed. The system will offer personalizable radio programs to listeners and it will enable radio stations to gather valuable information about their listeners. Furthermore, this paper points out key challenges in deploying, bootstrapping and maintaining such a distributed system.}

In der Konsequenz ist ihr Umsatz zwischen 2001 und 2011 um die Hälfte zurückgegangen. Junge, agile Unternehmen wie spotify und branchenfremde Riesen wie Amazon haben diese Chance erkannt und einen neun Markt für digitale Musikangebote etabliert, von  dem traditionelle Radiosender verdrängt werden. Um das zu verhindern, wird in dem Forschungsprojekt HbbRadio ein personalisierbares Live-Radio entwickelt. Dieser Hybrid aus herkömmlichem digitalen Rundfunk und Internetverbindung ermöglicht es Hörern, Musikstücke aus dem normalen Radiosignal durch „bessere" Stücke zu ersetzen. Gleichzeitig dient eine  (mobile) Internetverbindung als Rückkanal zum Sender. Die Hörerschaft und deren musikalische Vorlieben können darüber in Echtzeit analysiert werden. Das bedeutet nicht nur einen enormen Umbruch für den traditionellen Markt. Damit treten Radiosender plötzlich in Konkurrenz zu weltweit agierenden Streaming-Anbietern wie spotify und last.fm, deren Dienste zuweilen auch kostenlos genutzt werden können. Warum das verlockende Chancen bietet und warum Radiosender sich auf dieses Abenteuer einlassen sollten, beleuchtet dieser Artikel.}

   abstract={Modern databases tailored to highly distributed, fault tolerant management of information for big data applications exploit a classical data structure for reducing disk and network I/O as well as for managing data distribution: The Bloom filter. This data structure allows to encode small sets of elements, typically the keys in a key-value store, into a small, constant-size data structure. In order to reduce memory consumption, this data structure suffers from false positives which lead to additional I/O operations and are therefore only harmful with respect to performance. With this paper, we propose an extension to the classical Bloom filter construction which facilitates the use of floating point coprocessors and GPUs or additional main memory in order to reduce false positives. The proposed data structure is compatible with the classical construction in the sense that the classical Bloom filter can be extracted in time linear to the size of the data structure and that the Bloom filter is a special case of our construction. We show that the approach provides a relevant gain with respect to the false positive rate. Implementations for Apache Cassandra, C++, and NVIDIA CUDA are given and support the feasibility and results of the approach.}

Additionally, online social networks usually contain enough highly private information for personalization, but this information has been seldom used in modifying the social graph structure. With this paper, we define the novel paradigm of context-centric online social networking in which the social graph structure is derived from context-information alone. We show how a context-centric network based on Wi-Fi location information as well as geohash-based GPS location can be deployed using a specific metadata construction. We support our definitions with a location-based service relying on the metadata model and illustrating spatial and temporal awareness.}

abstract={Due to the rise of mobile computing and smartphones, a lot of information about groups has become accessible. This information shall often be kept secret. Hence distributed algorithms for privacy-preserving distribution estimation are needed. Most research currently focuses on privacy in a database, where a single entity has collected the secret information and privacy is ensured between query results and the database. In fully distributed systems such as sensor networks it is often infeasible to move the data towards a central entity for processing. Instead, distributed algorithms are needed. With this paper we propose a fully distributed, privacy-friendly, consensus-based approach. In our approach all nodes cooperate to generate a sufficiently random obfuscation of their secret values until the estimated and obfuscated values of the individual nodes can be safely published. Then the calculations can be done on this replacement containing only non-secret values but recovering some aspects (mean, standard deviation) of the original distribution.},

  abstract = {Interest dissemination in constrained environments such as wireless sensor networks utilizes Bloom filters commonly. A Bloom filter is a probabilistic data structure of fixed length, which can be used to encode the set of sensor nodes to be awake. In this way an application can disseminate interest in specific sensor nodes by broadcasting the Bloom filter throughout the complete wireless sensor network. The probabilistic nature of a Bloom filter induces false positives, that is some sensor nodes will be awake without the application having interest in their sensor values. As the interest is often depending on location such as in adaptive sampling applications, we present a novel method to encode both interest and possible location of information into one probabilistic data structure simultaneously. While our algorithm is able to encode any kind of tree-structured information into a fixed length bit array we exemplify its use through a wireless sensor network. In comparison to traditional Bloom encoding techniques we are able to reduce the overall number of false positives and furthermore reduce the average distance of false positives from the next true positive of the same interest. In our example this helps to reduce the overall energy consumption of the sensor network by only requesting sensor nodes that are likely to store the requested information.},

Moreover, the measurement data is typically stable over time at a fixed location and can thus be replayed at later times.

Therefore, a self-contained system is generating signed one-time passwords and communicates them via 2D barcodes for authentication of camera-enabled devices being in a specific location.},
