SURI – Summer Research Institute / Security and Privacy edition
The Summer Research Institute (SuRI) is an annual event that takes place at the School of Computer and Communication Sciences of the École polytechnique fédérale de Lausanne, Switzerland.
This year the workshop will be bringing together 17 researchers and experts from academia and industry for research talks and informal discussions, including a poster session.
Exploring Artificial Intelligence to Predict Complications after Major Digestive Surgery
Major digestive surgery is associated with a high comorbidity (i.e. high risk of complications after surgery). Anticipating Postoperative complications (POC) may help and guide clinicians in the postoperative management of surgical patients. Unfortunately, the available tools in clinical practice are of restraint value due to their limited accuracy. Recently, artificial intelligence (AI) has shown a meteoric rise in medicine, showing numerous clinical applications but its role to predict POC remains unknown. We aim to use AI to develop new models allowing to improve the prediction of POC in a dataset of >2000 patients undergoing major digestive surgery.
Machine-Learning Prognostication in Patients Undergoing Surgery for Hepatocellular Carcinoma (Liver Cancer)
Liver cancer is the second deadliest malignancy. It essentially accounts hepatocellular carcinoma (HCC). Surgery with liver resection is the main curative option but unfortunately, it is only recommended in patients with early HCC. Prognosis of HCC is particularly challenging and results from numerous attempts using various strategies remain relatively poor.Artificial intelligence (AI) has demonstrated unmatched value to decipher complex traits and mechanisms. This multicentric effort will include 8 Academic centers from the United States, Europe and Asia, allowing to generate a large-scale dataset of patients undergoing liver resection for HCC. We aim to investigate the input of AI to improve prognostication of these patients.
Using Artifical Intelligence to Explore the Prognostic Value of Macroscopy in Liver Cancer
Liver cancer ranks third in terms of cancer-related mortality. Hepatocellular carcinoma (HCC) accounts for 90% of primary liver cancers. Tremendous efforts have been pursued to establish HCC prognostic, including clinical, radiological, pathological and even molecular readouts. Regardless of the strategy, the performance of these tools remains modest. Recent data using artificial intelligence (AI) on HCC histology (microscopy) have revealed promising results. We aim to submit pictures of liver cancers specimen to AI models to generate algorithms allowing to establish prognosis in a large-scale study including centers from North America, Europe and Asia.
Demystifying the Commercial Potential of Privacy-Enhancing Technologies
By 2025 the total amount of data created, captured and consumed is predicted to reach 175 zettabytes. However, much of that data’s value is being wasted due to distrust, as there is fear that the data would be exposed when used, computed on or shared with collaborators, possibly leading to trade secrets being leaked or data protection legislation fines.
Vitalik’s answers to the big questions
I found this nice twitter thread from Vitalik Buterin, the inventor of the Ethereum blockchain: Doing a random twitter experiment just on this day. Only the 268 people I follow can reply to this tweet. Feel free to ask things and I'll talk about anything crypto or non-crypto related. — vitalik.eth (@VitalikButerin) September 1, 2021 (…)
12 Questions on the Digital Immunity Passport
The certificate linked to the virus will not be available before June in Switzerland. Until then, here are twelve answers linked to questions of security, data and accessibility concerning what some call the “Immunity Passport”. In particular, Jean-Pierre Hubaux, C4DT Academic Director, provides insights on the questions linked to data.
Prof. Jean-Pierre Hubaux’s opinion piece in ‘LeTemps” on Trusting SwissCovid App
French-language news paper ‘Le Temps’ published an opinion piece by C4DT’s Academic Director and Head of the LDS lab at EPFL, Jean-Pierre Hubaux, on trusting the SwissCovid app. Prof. Hubaux raises the point that the excessive focus on privacy protection has cast doubt on a tool which makes it possible to defend other rights.

Joint C4DT-CyberPeace Institute-CTEI conference on “Manipulating elections in cyberspace: are democracies in danger?”
Increasingly, reports warn that state-sponsored actors use social media to spread fake news/disinformation in order to sow distrust and create panic during pandemics and create discord and polarized opinions among people on political issues during democratic elections. Adding to this, social media platforms’ algorithms “add salt to the wound” by feeding their users posts which are aligned with their opinion in order to increase their screen time. How serious and how massive is the problem? What are its implications? And what can/should be done about it?
During this forum, organized jointly by the Center for Digital Trust (C4DT), the CyberPeace Institute and the Graduate Institute’s Centre for Trade and Economic Integration (CTEI) in Geneva, we will discuss not only the technological aspects of this phenomena, but also the regulatory role executive and legislative branches of governments should play. Societal, economical and geopolitical implications will also be debated. This event is open to the general public.

Launch of the CyberPeace Institute in Geneva
Thursday 26 September 2019 saw the launch of the CyberPeace Institute, an independent NGO that will address the growing impact of major cyberattacks, assist vulnerable communities, promote transparency, and advance global discussions on acceptable behavior in cyberspace. EPFL President Martin Vetterli will be sitting on the Executive Board, and the Center for Digital Trust is named as a scientific partner.
The C4DT is looking forward to working with the @cyberpeaceinst led by @DuguinStephane and @MarietjeSchaake and supporting its mission to enhance the stability of #cyberspace. Please click below to access the official announcement.
C4DT Distinguished Lecture : Talk by Dr. Dan Bogdanov, Cybernetica, Estonia
In this talk, Dan Bogdanov will start by introducing secure computing technologies and their potential in enterprise and government use. He will then look at a focus group study of the barriers of adopting such technologies based on interviews in many industries.

C4DT Distinguished Lecture : Hidden Backdoors in Deep Learning Systems
by Prof. Ben Zhao, Univ. of Chicago
The lack of transparency in today’s deep learning systems has paved the way for a new type of threats, commonly referred to as backdoor or Trojan attacks. In this talk, Ben Zhao will describe two recent results on detecting and understanding backdoor attacks on deep learning systems.

AI’s “Gut Feeling”: Should Society Trust It?
Inspired by the panel session at this year’s “AI House” panel session on “Transparency in Artificial Intelligence”, this write up very informally summarizes Imad Aad’s thoughts about transparency and trust in AI. It is aimed at readers with all backgrounds, including those who had little or no exposure to AI so far.
The Limits of Privacy-Preserving Data Publishing
This project underscores the need for a paradigm shift in data privacy policies, acknowledging the inherent trade-off between data utility and privacy that current Privacy Enhancing Technologies (PETs) cannot fully mitigate. It highlights the limitations of PETs and the systemic responsibility issues within the data supply chain, where technology producers often evade accountability. Consequently, a shift towards a data-use case-centric evaluation framework is recommended, one that prioritizes utility while minimizing leakage through nuanced risk assessments. Finally, the porject calls for greater transparency and a redefined accountability structure in the data sharing ecosystem.

The Swiss Confederation E-ID Public Sandbox Trust Infrastructure
Switzerland’s E-ID journey so far In 2021, the Swiss E-ID law proposition was rejected by a public referendum. The reason for the refusal was due to privacy concerns in the implementation and management of that system. In a nutshell, the idea that a private entity would be in control of users’ data was frowned upon. (…)
