Towards sovereign domains P2P overlays in blockchain systems

Blockchain technology has proven to be a promising solution for decentralized systems in various industries. At the core of a blockchain system is the peer-to-peer (P2P) overlay, which facilitates communication be- tween parties in the blockchain system. Recently, there is increasing evidence that this P2P overlay plays a major role in limited...

Privacy-preserving cross-device tracking

Online advertisement is a multi-billion dollar industry that constitutes a primary source of income for most publishers offering free content on the Web. Online behavioural advertisement refers to the practice of serving targeted ads to online users based on their potential interests. In order to infer these interests, online advertisers...

Predicting Near-Future Demand of Self-Storage Rooms

The value of data has increased enormously over the last couple of years. Many datasets contain valuable information that can, for example, be used to make forecasts. In this thesis, the dataset of a company in the self-storage industry is analyzed. The company offers customers rental storage facilities, such as lockers, rooms, containers at...

Out of Sight, Out of Mind: A Comprehensive Study on the Prevalence and Security Impact of Orphaned Web Pages

Security misconfigurations and neglected updates commonly lead to systems being vulnerable. Ranging from default passwords to unpatched software, many systems, such as websites or databases, are being compromised due to these pitfalls. Often stemming from human error, it is difficult to avoid these misconfigurations, which is why they are...

AI Soccer: the Most Effective Methods to Dispossess the Opponent Player

In this paper, one of the challenges that comes with defending in AI soccer is highlighted and an attempt is made in finding a solution for the problem. In soccer, defense is an important part of the game and the research question in this research is formulated as follows: what are the most effective methods to take by surprise and dispossess...

Defensive Positioning Strategies For A Goalkeeper In The AI World Cup

The AI World Cup is a virtual competition in which teams of five players compete in a football match. The defensive strategies for the goalkeeper in this environment are yet to be researched, however. In previous editions of the competition the participating teams use a basic goalkeeper that can only dive but not position itself. This project...

Where to Score in AI World Cup Football?

To push the boundaries of technology, the world cup football for robots, RoboCup, is organized on a yearly basis since 1997. To push the boundaries of artificial intelligence, a simulated version of the RoboCup, AI World Cup Football, is arranged yearly from 2017. This requires skillful attackers, defenders and goalkeeper. A large part of having...

AI soccer: covering an opponent not in possession of the ball

Virtual robot soccer competitions have been rising in popularity in recent years, due to their easier accessibility than physical robot soccer. This is also the reason these virtual competitions were created. The goal is to compete in the AI world cup, one of the virtual soccer competitions. A coach-based framework has already been built, and...

Facing the ball carrier in AI World Cup soccer

Robot soccer competitions have been around for a while and have been a great environment to develop AI algorithms in. One of these environments is the AI world cup. The AI world cup environment is a virtual environment where two teams with five robots each play a soccer match. This paper focuses on defending the attacker that is carrying the...

Understanding Context Effects in the Evaluation of Music Similarity

This work analyses context effect in the evaluation of music similarity performed by human annotators to better understand the impact of context effects in the current annotation protocol of Music Information Retrieval Evaluation eXchange (MIREX). Human annotators are known to be subjective when giving similarity judgements. The Audio Music...

Minimally-Interactive Protocols for Privacy-Preserving Set and Multiset Operations Between Multiple Parties

In our increasingly digital society, we are making a growing amount of data available to computers, networks and third parties. As a consequence, our sensitive data is in danger of getting exposed. The field of multi-party computation attempts to mitigate this by studying protocols that enable parties to perform their operations digitally,...

Generating Private Contrastive Explanations with Differentially Private Classifiers and Foil Trees

Due to the rapid growth of diseases like diabetes, machine-learning (ML) advanced clinical decision support systems (CDSS) that support doctors or patients in their care might prove to be a valuable asset. In the battle to make healthcare more accessible, adopting ML techniques could be supportive in increasing the overall<br/>effectiveness and...

Privacy-Preserving Data Aggregation with Probabilistic Range Validation

Privacy-preserving data aggregation protocols have been researched widely, but usually cannot guarantee correctness of the aggregate if users are malicious. These protocols can be extended with zero-knowledge proofs and commitments to work in the malicious model, but this incurs a significant computational cost on the end users, making adoption...

An Elliptic Curve Cryptography Acceleration Core for OpenVPN on an FPGA Softcore

Elliptic Curve Cryptography (ECC) performance is a major performance bottleneck when serving many VPN clients from a single server on a low-frequency FPGA softcore CPU. Using an area-efficient Elliptic Curve Point (ECP) multiplication accelerator core on the same FGPA, a much higher amount of clients can be served using the same FPGA chip. Using...

Little or Large?: The effects of network size on AI explainability in Side-Channel Attacks

For a system to be able to interpret data, learn from it, and use those learnings to reach goals and perform tasks is what it means to be intelligent [1]. Since systems are not a product of nature, but rather made by humans they are called Artificial Intelligence (AI). The field of Side-Channel Attacks (SCA) has benefited from applying AI...

Circumventing Secure JTAG: A detailed plan of attack

Forensic science is the cornerstone of the modern justice system, as it allows us to analyze evidence in order to discover the truth behind a crime scene. As mobile phones became more important to our daily lives they've taken up a bigger part in forensic research as well. These devices contain digital traces telling us the story of our lives....
