Privacy in Speech and Language Technology (Dagstuhl Seminar 22342)

Authors: Simone Fischer-Hübner, Dietrich Klakow, Peggy Valcke, and Emmanuel Vincent

Published in: Dagstuhl Reports, Volume 12, Issue 8 (2023)


Abstract
This report documents the outcomes of Dagstuhl Seminar 22342 "Privacy in Speech and Language Technology". The seminar brought together 27 attendees from 9 countries (Australia, Belgium, France, Germany, the Netherlands, Norway, Portugal, Sweden, and the USA) and 6 distinct disciplines (Speech Processing, Natural Language Processing, Privacy Enhancing Technologies, Machine Learning, Human Factors, and Law) in order to achieve a common understanding of the privacy threats raised by speech and language technology, as well as the existing solutions and the remaining issues in each discipline, and to draft an interdisciplinary roadmap towards solving those issues in the short or medium term. To achieve these goals, the first day and the morning of the second day were devoted to 3-minute self-introductions by all participants intertwined with 6 tutorials to introduce the terminology, the problems faced, and the solutions brought in each of the 6 disciplines. We also made a list of use cases and identified 6 cross-disciplinary topics to be discussed. The remaining days involved working groups to discuss these 6 topics, collaborative writing sessions to report on the findings of the working groups, and wrap-up sessions to discuss these findings with each other. A hike was organized in the afternoon of the third day. The seminar was a success: all participants actively participated in the working groups and the discussions, and went home with new ideas and new collaborators. This report gathers the abstracts of the 6 tutorials and the reports of the working groups, which we consider as valuable contributions towards a full-fledged roadmap.

Pattern Discovery in Colored Strings

Authors: Zsuzsanna Lipták, Simon J. Puglisi, and Massimiliano Rossi

Published in: LIPIcs, Volume 160, 18th International Symposium on Experimental Algorithms (SEA 2020)


Abstract
We consider the problem of identifying patterns of interest in colored strings. A colored string is a string in which each position is colored with one of a finite set of colors. Our task is to find substrings that always occur followed by the same color at the same distance. The problem is motivated by applications in embedded systems verification, in particular, assertion mining. The goal there is to automatically infer properties of the embedded system from the analysis of its simulation traces. We show that the number of interesting patterns is upper-bounded by 𝒪(n²) where n is the length of the string. We introduce a baseline algorithm with 𝒪(n²) running time which identifies all interesting patterns for all colors in the string satisfying certain minimality conditions. When one is interested in patterns related to only one color, we provide an algorithm that identifies patterns in 𝒪(n²log n) time, but is faster than the first algorithm in practice, both on simulated and on real-world patterns.

Online Privacy: Towards Informational Self-Determination on the Internet (Dagstuhl Perspectives Workshop 11061)

Authors: Simone Fischer-Hübner, Chris Hoofnagle, Ioannis Krontiris, Kai Rannenberg, and Michael Waidner

Published in: Dagstuhl Manifestos, Volume 1, Issue 1 (2011)


Abstract
While the collection and monetization of user data has become a main source for funding ``free'' services like search engines, online social networks, news sites and blogs, neither privacy-enhancing technologies nor its regulations have kept up with user needs and privacy preferences. The aim of this Manifesto is to raise awareness for the actual state of the art of online privacy, especially in the international research community and in ongoing efforts to improve the respective legal frameworks, and to provide concrete recommendations to industry, regulators, and research agencies for improving online privacy. In particular we examine how the basic principle of informational self-determination, as promoted by European legal doctrines, could be applied to infrastructures like the internet, Web 2.0 and mobile telecommunication networks.

Authors: Simone Fischer-Hübner, Chris Hoofnagle, Kai Rannenberg, Michael Waidner, Ioannis Krontiris, and Michael Marhöfer

Published in: Dagstuhl Reports, Volume 1, Issue 2 (2011)


Abstract
The Dagstuhl Perspectives Workshop "Online Privacy: Towards Informational Self-Determination on the Internet" (11061) has been held in February 6-11, 2011 at Schloss Dagstuhl. 30 participants from academia, public sector, and industry have identified the current status-of-the-art of and challenges for online privacy as well as derived recommendations for improving online privacy. Whereas the Dagstuhl Manifesto of this workshop concludes the results of the working groups and panel discussions, this article presents the talks of this workshop by their abstracts.
