Welcome to CITP News. Catch up on the various ways in which CITP research on artificial intelligence, privacy and security, web3 and other digital technologies is informing the tech community, policy, and media — across the globe, and at home.

CITP Tools Help Journalists Break Story About Hospitals Sharing Patient Data with Facebook
The investigative journalism site, The Markup, revealed in its June 16 story, Facebook Is Receiving Sensitive Medical Information from Hospital Websites, that 33 top hospitals in the country have been sharing patient data with Facebook via trackers embedded on their websites known as Meta Pixels.

The Markup was able to discover the tracking using tools co-developed by a team of CITP computer scientists led by Princeton Computer Science Professor Jonathan Mayer, a member of CITP’s faculty. The coding CITP designed allowed The Markup site to see how Facebook’s Meta Pixel tracked ordinary patients who were logging into patient portals.

CITP built the tools as part of a Mozilla Rally research initiative that uses crowdsourcing to investigate the behaviors of platforms like Facebook. As a result of the Markup’s reporting, several hospitals removed the Meta Pixels from their websites.

Federal Trade Commission Report on AI Tools Cites Multiple CITP Papers
The FTC this month sent Congress a 78-page report, Combatting Online Harms Through Innovation, calling for accountability among firms that deploy artificial intelligence technologies designed to counter harmful online content, and warning that such AI tools could be faulty. The FTC report cites several CITP documents:


With political campaigns spending millions of dollars to advertise on platforms like Facebook, Google and TikTok, a new paper from CITP researchers and scholars Orestis Papakyriakopoulos, Christelle Tessono, Arvind Narayanan and Mihir Kshirsagar digs into more than 800,000 ads and 2.5 million videos tied to the 2020 presidential election to evaluate how well these platforms moderate political content. Their paper, How Algorithms Shape the Distribution of Political Advertising: Case Studies of Facebook, Google, and TikTok, will be presented at the Artificial Intelligence, Ethics, and Society (AIES) Conference at the University of Oxford in August.

CITP Researcher Angelina Wang presented a talk entitled, "Measuring Representational Harms in Image Captioning," at the ACM Conference on Fairness, Accountability, and Transparency in Seoul, South Korea.

CITP Researcher Anunay Kulshrestha and CITP Faculty Jonathan Mayer will present their paper, Estimating Incidental Collection in Foreign Intelligence Surveillance: Large-Scale Multiparty Private Set Intersection with Union and Sum at USENIX Security '22 in August. The paper proposes a new approach to estimating the scale at which U. S. intelligence agencies intercept communications without a warrant, using secure multiparty computation.


CITP Founder Ed Felten was interviewed in the June 17 episode of the Epicenter Podcast on the topic, “Arbitrum: The Layer 2 Scaling Solution For Ethereum.”


Former CITP researcher Carsten Schwemmer announced on Twitter that he will join the Department of Sociology at Ludwig-Maximilians-Universität (LMU) München in Germany as a Computational Social Science professor.



Congratulations to CITP Associated Faculty member Olga Russakovsky, an assistant professor in the Computer Science Department, on winning a National Science Foundation career award for her work related to Overcoming bias in computer vision: Building fairer systems and training diverse leaders. Russakovsky also co-directs Princeton AI4ALL, a program that brings high school students from groups underrepresented in computing to the Princeton campus for 3 weeks to learn about Artificial Intelligence.

The Center for Information Technology is a nonprofit, nonpartisan, interdisciplinary hub where researchers study the impact of digital technologies on society, with the mission of informing policymakers, journalists and the public for the good of society. CITP's programming includes a Technology and Society undergraduate certificate, a Tech Policy Clinic, a Public Interest Technology Summer Fellowship, and an Emerging Scholars in Technology program.

CITP is an initiative of Princeton University’s School of Engineering and Applied Sciences (SEAS) and the School of Public and International Affairs (SPIA)
