Query: Cardea: Context-Aware Visual Privacy Protection from Pervasive Cameras   The growing popularity of mobile and wearable devices with built-in cameras,
the bright prospect of camera related applications such as augmented reality
and life-logging system, the increased ease of taking and sharing photos, and
advances in computer vision techniques have greatly facilitated people's lives
in many aspects, but have also inevitably raised people's concerns about visual
privacy at the same time. Motivated by recent user studies that people's
privacy concerns are dependent on the context, in this paper, we propose
Cardea, a context-aware and interactive visual privacy protection framework
that enforces privacy protection according to people's privacy preferences. The
framework provides people with fine-grained visual privacy protection using: i)
personal privacy profiles, with which people can define their context-dependent
privacy preferences; and ii) visual indicators: face features, for devices to
automatically locate individuals who request privacy protection; and iii) hand
gestures, for people to flexibly interact with cameras to temporarily change
their privacy preferences. We design and implement the framework consisting of
the client app on Android devices and the cloud server. Our evaluation results
confirm this framework is practical and effective with 86% overall accuracy,
showing promising future for context-aware visual privacy protection from
pervasive cameras.
