Measuring Online Behavioural Advertising and Other Adventures in Data Protection & Data Economics

Wednesday, December 4, 2019


ISI seminar room 1st floor

Nikolaos Laoutaris Research professor at IMDEA Networks Institute Madrid

In this talk I will present our results on detecting behavioural targeting in online advertising and will cover the two families of methods that we have developed for this problem, based on 1) content-based analysis for identifying correlations between visited web-pages and obtained ads, and 2) frequency-based analysis using only impression counts to detect ads that follow a user across domains. I'll also cover my initial work on establishing transparency around online price discrimination, as well as how this work lead to the creation of the Data Transparency Lab while at Telefonica. I will complete my talk by introducing my new line of work around Human-Centric Data Economies and the related research group I am building at IMDEA Networks.
