Workshop on Usable Privacy & Security for Mobile Devices (U-PriSM)


The U-PriSM workshop is an opportunity for researchers and practitioners to discuss research challenges and experiences around the usable privacy and security of mobile devices (smartphones and tablets).


The workshop seeks two types of original submissions: (1) short papers describing new research outcomes and (2) position papers describing new research challenges and worthy topics to discuss in all areas of usable privacy and security of mobile devices. Submissions should relate to both usability and either privacy or security in mobile devices (smartphones or tablets).

Workshop papers will be available on the SOUPS website, but will not be included in the ACM Digital library. Authors of accepted papers will be invited to present their work at the workshop.
