Detection of private information in documents based on federated learning

The overall goal of this project is to train neural network models to extract private information from text including texts from scribed meetings, legal documents, medical data and so on.

Description

Data privacy is a becoming increasingly important with Data Protection Laws in Canada and the General Data Protection Regulation in European Union. The overall goal of this project is to train neural network models to extract private information from text including texts from scribed meetings, legal documents, medical data and so on. These models are supervised and require training data; however, training datasets are themselves subject to privacy. The outcome of this project will be a dataset of documents that contains private information of fictitious people and the labels that correspond to their private information as well as federated learning algorithms for detecting this private information.


Objectives

  • Software will be developed that will, for the application of interest, automatically collect pages from Internet and modify them to add privacy information. When private information is generated, the document will be annotated with the label that corresponds to a privacy type including name, email address, address, and affiliation and so on.
  • Development and training of the networks for federated learning that can be used to extract private information about people without exchanging data between the multiple sites.
