The majority personal information available online is now in some sense user-generated and most of this is subsequent to further processing by service providers pushing, structuring and aggregating the content. The new ecosystem raises unprecedented challenges for the data protection framework both as regards the safeguarding of users themselves and the allocation of responsibility between them and service providers for the protection of the rights of other individuals who may be identifiable in the published data.
In the annual WYNG-Hatton Lecture, delivered on 9 November 2016 at the University of Hong Kong, Dr David Erdos explored these issues from both an historical and contemporary perspective concentrating especially on the case examples of health discussion forums, the publication of data from internet of things tracking devices and the responsibilities of search engines in the wake of the "right to be forgotten" ruling in Google Spain (2014).
