Reliable Microsecond-Scale Distributed Computing
The landscape of computing is changing, thanks to the advent of modern networking equipment that allows machines to exchange information in as little as one microsecond. Such advancement has enabled microsecond-scale distributed computing, where entire dis ...
EPFL2023An Exploratory Study of Reactions to Bot Comments on GitHub
Denis Gillet, Juan Carlos Farah, Sandy Ingram, Xinyang Lu
The widespread use of bots to support software development makes social coding platforms such as GitHub a particularly rich source of data for the study of human-bot interaction. Software development bots are used to automate repetitive tasks, interacting ...
ACM2022The Role of Compromised Accounts in Social Media Manipulation
In recent years we have seen a marked increase in disinformation including as part of a strategy of so-called hybrid warfare. Adversaries not only directly spread misleading content but manipulate social media by employing sophisticated techniques that exp ...
EPFL2022Children, Robots, and Virtual Agents: Present and Future Challenges
Shruti Chandra, Elmira Yadollahi
Research on child-agent interaction is rapidly expanding. It is, therefore, necessary to converge our collective efforts to broaden our understanding and perspectives of how virtual agents, affect and potentially improve the well-being of children. "Childr ...
ASSOC COMPUTING MACHINERY2021Integrity and Metadata Protection in Data Retrieval
Secure retrieval of data requires integrity, confidentially, transparency, and metadata-privacy of the process. Existing protection mechanisms, however, provide only partially these properties: encryption schemes still expose cleartext metadata, protocols ...
EPFL2021Mneme: A Mobile Distributed Ledger
Boi Faltings, Sujit Prakash Gujar, Dimitrios Chatzopoulos
Advances in mobile computing have paved the way for new types of distributed applications that can be executed solely by mobile devices on device-to-device (D2D) ecosystems (e.g., crowdsensing). More sophisticated applications, like cryptocurrencies, need ...
IEEE2020Automatic Online Fake News Detection Combining Content and Social Signals
Stefano Moret, Gabriele Ballarin
The proliferation and rapid diffusion of fake news on the Internet highlight the need of automatic hoax detection systems. In the context of social networks, machine learning (ML) methods can be used for this purpose. Fake news detection strategies are tra ...
IEEE2018Oblivious Dynamic Searchable Encryption on Distributed Cloud Systems
Dynamic Searchable Symmetric Encryption (DSSE) allows search/update operations over encrypted data via an encrypted index. However, DSSE has been shown to be vulnerable to statistical inference attacks, which can extract a significant amount of information ...
SPRINGER INTERNATIONAL PUBLISHING AG2018Trusted Registration, Negotiation, and Service Evaluation in Multi-Agent Systems throughout the Blockchain Technology
Michael Ignaz Schumacher, Alevtina Dubovitskaya
Some recent trends in distributed intelligent systems rely extensively on agent-based approaches. The so-called Multi Agent Systems (MAS) are taking over the management of sensitive data on behalf of their producers and users (e.g., medical records, financ ...
IEEE2018Atom: Horizontally Scaling Strong Anonymity
Bryan Alexander Ford, Henry Nathaniel Corrigan-Gibbs
Atom is an anonymous messaging system that protects against traffic-analysis attacks. Unlike many prior systems, each Atom server touches only a small fraction of the total messages routed through the network. As a result, the system’s capacity scales near ...
