Kroskinski, Ivo (author)Organizations use cloud service providers for outsourcing their data, since this includes advantages such as: scalability, security and no need for in house experts. Therefore, outsourcing data to cloud providers results in reduced costs. <br/>The disadvantage of outsourcing data to a cloud provider, is that organizations are not in control of...master thesis 2023

Hristov, Tsvetomir (author)Although digital watermarking has been a well-researched topic for the past decades and has seen numerous implementations for relational databases, it still lacks research for non-relational schema-less databases. In this paper, we explore proposed techniques for non-relational database watermarking and introduce an improved technique for NoSQL...bachelor thesis 2023

Nierop, Jaden (author)Digital watermarking has been used extensively in media in recent years. Yet, there are still relatively few techniques for watermarking 3D meshes. In this paper we implement a watermarking algorithm proposed by O. Benedens that encodes a bit string in the distribution of the normals of the faces of the mesh and investigate a method to improve...bachelor thesis 2023

Maesen, Palle (author)The media watermarking technique domain has had the last 30 years to develop itself. The non-media side, however, is a way newer sub-domain. [1] The data-gathering process for machine learning algorithms is a tedious and time consuming task. This becomes worse as the scale of these algorithms increases. Thus, protecting the datasets against...bachelor thesis 2023

de With, Wim (author)Recommender systems usually base their predictions on user-item interaction, a technique known as collaborative filtering. Vendors that utilize collaborative filtering generally exclusively use their own user-item interactions, but the accuracy of the recommendations may improve if several vendors share their data. Since user-item interaction...master thesis 2022

Palazzo, Marco (author)Large amounts of data are continuously generated by individuals, apps, or dedicated devices. These data can be aggregated to compute useful statistics from multiple sources using data aggregation protocols. However, oftentimes these data contain private information that must be protected from misuse. Privacy-preserving protocols can help to...master thesis 2022

Shen, Yu (author)Payment channel networks (PCNs) are a promising solution to the blockchain scalability problem. They move payments off-chain, i.e., not all payments have to be included in the blockchain. Thus, they do not require that every payment is broadcast to all participants and verified by them. Not requiring global consensus reduces latency, computation...master thesis 2022

Memar Zahedani, Armin (author)Double Auctions are mechanisms to trade commodities such as electricity or parts of the wireless spectrum at optimal prices. Bidders and sellers simultaneously submit quantity-price pairs to an auctioneer, denoting the quantity they want to buy or sell at specific prices. The auctioneer aggregates the offers into demand and supply curves to...master thesis 2022

Karahan, Asli (author)Healthcare recommender systems emerged to help patients make better decisions for their health, leveraging the vast amount of data and patient experience. One type of this system focuses on recommending the most appropriate physician based on previous patient feedback in the form of ratings. Such advice can be challenging to generate for new...master thesis 2022

Hondelink, Dieuwer (author)Digital signatures are used everywhere around us. They are well-studied and have been standardized since 1994. In 2002, Johnson et al. introduced the notion of homomorphic digital signatures, allowing one to perform computations on signed data. These signatures are especially useful for linear network coding, a technique used to improve...master thesis 2022

Kollár, Eniko (author)Globally, it is estimated by the UN that 2% - 5% of the annual GDP is lost to money laundering. Cur-rent anti-money laundering efforts are hindered by both the lack of trust between financial institutions internationally and the presence of local privacy regulations like GDPR. This makes it unfeasible to share plain transaction data between...bachelor thesis 2021
