Speech Title: Understanding Deepfakes: Human Judgements and Business Implications
Abstract: Deepfakes are artificially created media posing as actual video recordings and are a potential source of fake news or disinformation. Although research has been done in developing algorithms for the automatic detection of deepfakes, there needs to be more work conducted on how users identify deep fakes. This is a critical missing link because algorithms are currently not performing at a level where human judgement is unneeded. This presentation will discuss the verification strategies users adopt when engaging with content from deepfakes and the implications on businesses and societies.

Because people are the key element in the success of any crowdsourcing project, motivating and sustaining participation is an active research area. There are a variety of ways to foster participation in crowdsourcing projects, including appealing to altruism and providing compensation. Each method has advantages and drawbacks.
In this talk, we consider computer games as a promising means to attract crowdsourcing participants. Known as crowdsourcing games, they capitalize on people's desire for enjoyment, and aim to make crowdsourcing entertaining and engaging. However, like other motivational methods, designing game-based approaches are challenging because they have to meet the twin goals of engaging users and generating quality crowdsourced contributions. Put differently, a game that dwells too much on entertainment may result in users losing sight of the underlying crowdsourcing purpose, while conversely, a game that focuses primarily on the crowdsourcing task may not be engaging enough to encourage participation…
