Insights into internet privacy for visually impaired and blind people

Abstract

Tracking blockers protect from and inform about hidden trackers and services that collect data in the background while the user is surfing the web. However, existing tracking blockers provide information and feedback visually and thus are barely accessible for visually impaired and blind users. In this paper we present insights about privacy concerns of visually impaired Internet users. Moreover we present feedback strategies and guidelines for an accessible tracking blocker developed in a user centered design process. The underlying feedback principles and guidelines can be used for the design of Privacy Enhancing Technology in other domains, and therefore serve as reference for designers and developers.
