Workshop on Design Issues for a data Anonymization Competition (WODIAC)

The analysis of large scale datasets, often refer to as Big Data, offers the possibility to realize inferences with an unprecedented level of accuracy and details. However, this massive collection of information also raises many privacy issues since most of these datasets contain personal information, which is thus sensitive by nature. As a result, only very few of them are released and available, which limits both our ability to analyze such data to derive useful knowledge that could benefit to the public and the society at large and slows down the innovative services that could emerge from such data. Thus, an important scientific and societal challenge is the design and study anonymization mechanisms that can be used to remove the sensitive information or add uncertainty to a dataset before it is released or before further services are developed on it.

To address this issue, we will organize a data anonymization competition, to be held in conjunction with PETS 2018, to study the strengths and limits of anonymization methods from an empirical perspective. The main objective of this workshop is to investigate the design issues related to the organization of such a competition:
The expected outcome of the workshop is a set of recommendations and guidelines to establish the competition.

Call for Contributed Talks

If you are interested to give a talk that fits within the scope of the workshop please send us a title and a one or two paragraphs description of our proposed presentation before June 25 to both of the chairs at the email addresses listed above. We are planning to release the detailed program of the workshop by the end of June. There will be no official proceedings but the expected outcome of the workshop will a set of recommendations and guidelines to establish the competition based on the presentations and exchanges generated during the workshop.

Important Dates:
