| [10:15-11:00] | Keynote 1 | By Prof. Feng Hao – University of Warwick Title: SEAL: sealed-bid auction without auctioneers Abstract: In this talk, I will present our recent work on e-auction. I will show how to combine standard zero-knowledge proof techniques with a novel Boolean logic to transform a simple Boolean-OR function to a MAX function. This results in a decentralized e-auction protocol that is dramatically more efficient than any previous schemes in terms of computation and communication complexity. Our work demonstrates, for the first time, that it is possible to securely and efficiently implement a Vickrey auction without involving any auctioneer. The removal of the dependence on any trustworthy auctioneers clears a major obstacle of deploying Vickrey auctions in practice, e.g., implementing them as smart contracts over an Ethereum-like blockchain.

| [13:30-14:15] | Keynote 2 | By Dr. Nikolaos Laoutaris, IMDEA Networks Title: Measuring Online Behavioural Advertising and Other Adventures in Data Protection & Data Economics Abstract: 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. Website: http://laoutaris.info/ |
