Now at #soups2015: Alexander De Luca (for Hang et al.) on using location-based security questions for fallback authentication

Maria Wolters @mariawolters

De Luca: Idea based on GeoPass (SOUPS 2013) and PassMap (ASIACCS 2012) #soups2015

#soups2015 attendees: Anyone got a android charger/USB cable that I could borrow for a couple of hours?

Maria Wolters @mariawolters

De Luca: Location-based questions can be very complex, with 1-4 pieces of information required to choose correct place #soups2015

Maria Wolters @mariawolters

De Luca: Users only made very few mistakes, some due to map changes or precision required. #soups2015

Christine Mekhail (she/her/elle) @cmekhail_ux

"Where's the centre of the route to your childhood friend?" great LBS security fallback authentication! #soups2015 bit.ly/1JiUEYF

Maria Wolters @mariawolters

De Luca: location based questions are highly memorable and hard to guess - perfect! #soups2015

Maria Wolters @mariawolters

Now: Al-Ameen et al. on how to make graphical passwords more memorable. Strategy: ensure rich, complex encoding #soups2015

Maria Wolters @mariawolters

Now at #soups2015: How to remember PINs. Very important as US is moving to chip and pin, and banks move to 6 digit pins. #soups2015

Martin Ortlieb @uxprivacy

Study on how chunking could help memorability of PINs goo.gl/elVhUn #soups2015

Maria Wolters @mariawolters

#soups2015 Comparison of 12 chunking policies, with at least one 4 digit chunk and smallest chunk size of 2.

Maria Wolters @mariawolters

PINs for memorization were presented chunked or not chunked. Impact of chunking policies v minor, 4 digit PINs worked best #soups2015

Now at #soups2015: How effective are hints for autobiographical authentication? presented by Yusuf Albararam

Maria Wolters @mariawolters

I really need to check the #soups2015 paper on remembering PIN numbers to see whether they determined the digit span of participants.

Maria Wolters @mariawolters

Autobiographical question generation based on who phoned / texted whom at a certain time or location at certain time #soups2015

Maria Wolters @mariawolters

#soups2015 based on autobiographical memory literature, events for the autobiographical questions are selected using equation #soups2015

Martin Ortlieb @uxprivacy

For autobiographical challenge questions still counts: the user has to #trust the provider! goo.gl/JH575h #soups2015

Maria Wolters @mariawolters

Additional hints are of the same form (previous calls / texts/ locations), but can be pos or neg #soups2015

Maria Wolters @mariawolters

Comment from #soups2015 audience: autobiographical questions based on phone history very vulnerable to phone hackers or NSA
