With the increasing ease with which users can take and post photos, the unintentional disclosure of sensitive information of various kinds through mistakes made while posting has become a problem. In this work, we focused on the privacy of people appearing in photos and developed a method called “PrivacyTag” for adaptively blurring their facial area in accordance with the communities to which they belong by using tags embedded with community-based privacy policies. We also evaluated a newly designed privacy tag and developed a prototype application for Facebook that uses this tag. %G English %Z TC 6 %Z WG 6.1 %2 https://inria.hal.science/hal-01768504/document %2 https://inria.hal.science/hal-01768504/file/978-3-319-68557-1_24_Chapter.pdf %L hal-01768504 %U https://inria.hal.science/hal-01768504 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-WG %~ IFIP-TC6 %~ IFIP-WG6-1 %~ IFIP-I3E %~ IFIP-LNCS-10595
