Title: Towards Usable and Practical Image Privacy

 Abstract: Today image hosting platforms are a popular way to store and share images with family members and friends. However, such platforms typically have full access to images raising privacy concerns. In this talk we motivate the need for image privacy protection techniques that preserve certain visual features in images while hiding other information, to balance privacy and usability in the context of cloud-based image storage services. We will explore privacy schemes that use cryptographic, adversarial perturbation and semantic perturbation approaches and discuss their pros and cons.
