Privacy Protection and Performance Enhancement in IoT Applications using Blockchain and Machine Learning Techniques

The Internet of Things (IoT) is producing significant amounts of data. Protecting this data from adversaries is therefore a prominent field of research. This paper conducts a review of the current state-of-the-art in the field of IoT integrated with Blockchain (BC) and Machine Learning (ML). The review focuses on the use of privacy and...

Keyword Search Shareable Encryption for Fast and Secure Data Replication

It has become a trend for clients to outsource their encrypted databases to remote servers and then leverage the Searchable Encryption technique to perform secure data retrieval. However, the method has yet to be considered a crucial need for replication on searchable encrypted data. It calls for challenging works on Dynamic Searchable...

Smart contracts in energy systems: A systematic review of fundamental approaches and implementations

Given the ongoing transition towards a more decentralised and adaptive energy system, the potential of blockchain-enabled smart contracts for the energy sector is being increasingly recognised. Due to their self-executing, customisable and tamper-proof nature, they are seen as a key technology for enabling the transition to a more efficient,...

Exploring the adoption of the dataBox in the University: Interaction design for the data subject's perspective

The recently introduced General Data Protection Regulation (GDPR) allows universities to use WiFi Access data for their research activities. The richness, ubiquity, and scalability of WiFi tracking make it an extremely relevant resource for studying the behavior and mobility patterns of groups and social systems. However, it is also a sensitive...

Verkenning locatiegegevens en sociale platforms

In deze rapportage hebben we ons verdiept in de wereld van de commerciële toepassingen van sensordata, waarin locatiegegevens van smartphones op grote schaal worden vastgelegd. Een beter inzicht in de wereld van de sociale en commerciële platforms zou ervoor moeten zorgen dat deze beter begrepen wordt door de geosector.

Improved privacy of dynamic group services

We consider dynamic group services, where outputs based on small samples of privacy-sensitive user inputs are repetitively computed. The leakage of user input data is analysed, caused by producing multiple outputs, resulting from inputs of frequently changing sets of users. A cryptographic technique, known as random user selection, is...

Open data and beyond: Exploring existing open data projects to prepare a successful open data strategy; Deelrapport privacy

Bij de selectie van welke datasets als open data kunnen worden aangeboden wordt privacy vaak genoemd als aandachtspunt. Dat is terecht want aandacht voor privacy is noodzakelijk bij het aanbieden van open data. Privacy is een van de mogelijke argumenten om voor bepaalde gegevens geen open data beleid toe te passen. Dit rapport is een uitwerking...
