Collaborative Research: SaTC: CORE: Medium: Broad Spectrum Facial Image Protection with Provable Privacy Guarantees

The goal of this project is to overcome the following challenges which have not been well studied: (i) Privacy protection for human subjects and sensitive objects in the background of the images which are usually ignored by the existing works; (ii) Consideration of location-dependent image sensitivities whereby images taken at certain places (e.g., pubs, hospitals) may impact privacy of some people in the images who do not want their occurrences or co-occurrences at those locations to be known; (iii) Need for a comprehensive privacy model that can determine the extent to which the privacy protection mechanism reduces practical privacy risks; (iv) Enforcing the privacy protection that conforms with different privacy needs of multiple people in the same image.
