Abstract: Privacy-enhancing mobile applications that employ anonymous digital signature (ADS) schemes can be beneficial for users who strongly concern about their privacy and security. This paper deals with ADS schemes and their usability on smartphones. We implement seven ADS schemes on smartphones in order to get the practical results. Further, we discuss the usability of these schemes in different scenarios such as data collection, access control and data notification. We believe that our analysis and performance assessment can help engineers and security experts to choose a proper ADS scheme into their secure and privacy-friendly mobile applications.

Keywords: ADS; anonymous digital signature; cryptography; group signature; performance evaluation; privacy.
