講座簡介：
Faces play an important role in decision making processes in many contexts (e.g., security screening, hiring decisions, online dating); yet, there is also a strong need to protect facial privacy. The authors propose a face anonymity-perceptibility (FAP) paradigm as a general framework for solving three types of tradeoff problems (non-perception, component perception and holistic perception) between face anonymization and face perception. Four different methods can be applied to achieve particular type(s) of tradeoffs: feature reduction and feature replacement from the computer vision literature, and two face abstraction methods (local abstraction and global abstraction) proposed by the authors and grounded in the social psychology and neuropsychology literature. The authors empirically test the FAP paradigm by applying the local abstraction and global abstraction methods to the online dating industry, where Type III (i.e., holistic perception) tradeoff is desired. The results demonstrate that both methods are effective in balancing face anonymization and perception. When evaluated on their predictive performances as screening tools, the proposed face abstraction-based screening (FAS) models generate a median relative improvement of 36.1% over a model without abstracted facial information.
