No existing evaluation infrastructure for shared tasks currently supports both reproducible on- and offline experiments. In this work, we present an architecture that ties together both types of experiments with a focus on reproducibility. The readers are provided with a technical description of the infrastructure and details of how to contribute their own experiments to upcoming evaluation tasks.<\/p>\n\n\n\n

In case of a server\u2019s corruption, all contacts are either directly available in plaintext or can be unmasked using a simple dictionary attack. To solve this problem, we present procd [p\u0281o\u02d0st] a python implementation for privacy preserving contact discovery. procd is a trustless solution that requires neither plaintext numbers nor hashes of single phone numbers to retrieve contacts. Instead, we transfer hashed combinations of multiple phone numbers, which increases the effort for dictionary attacks to an unfeasible level using today\u2019s hardware.<\/p>\n\n\n\n Keywords:<\/strong> private contact discovery; private set intersection; secure multi-party computation; private information retrieval<\/p>\n\n\n\n Long Paper<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":" Chair: Raphael Wimmer A Living Lab Architecture for Reproducible Shared Task Experimentation Timo Breuer, Philipp Schaer TH K\u00f6ln – University of Applied Sciences, Germany Abstract No existing evaluation infrastructure for shared tasks currently supports both reproducible on- and offline experiments.
