Note special time and day of week

Cognitive and psychological studies have revealed that humans perform far better at remembering pictures than words. This has inspired fast growing research into the design of graphical password systems in both the security and the HCI communities, in the expectation of delivering a graphical alternative to the ubiquitous textual password scheme (which has long suffered from usability problems). However, much work must be done to realise the benefits of the picture superiority effect, and make graphical passwords a usable and robust security solution. In this talk, I will present our recent work on designing graphical passwords that are both secure and usable for hand-held devices.
