Abstract

Our lives and society are digitized from every perspective by computers, smart devices and various information systems. A large amount of accounts are appearing and becoming essential tools to access resources and services in this digital age. Besides the power and convenience, people are also experiencing new challenges and difficulties in their use and protection of various accounts. The first part of this talk will present a recent study on account sharing practices in the workplace. Across two surveys, we will examine the sharing process at work, probing what accounts people share, how and why they share those accounts, and identifying the major challenges people face in sharing accounts. In the second part, a new authentication method to protect our account will be introduced. We will show it is possible to perform accurate account authentication with a single swipe on our touch screens. This may provide a possible option to save us from remembering different passwords to access large number of accounts when fingerprint and face recognition are not available.
