PassNum: A usable and secure method against repeated shoulder surfing.
Conventional PIN and password methods failed to be resilient against observational attacks. In the wake of usable security, this gap is filled with enormous proposals of graphical passwords that claim to be resistant but sacrifice the usability concerns in the shape of other afflictions (second devi...

In the wake of usable security, this gap is filled with enormous proposals of graphical passwords that claim to be resistant but sacrifice the usability concerns in the shape of other afflictions (second device 'phone/PC', headset, vibration motor, weird hand motions). In comparison, we propose PassNum, a grid-based usable, deployable, and secure graphical PIN authentication method (GPA) in the replacement (for every device) of conventional PIN. It is low-cost, user-friendly (child vs. old), secure (high entropy), and has a compatible design for low-sensitive (social sites) to more sensitive (banking apps). Through extensive experiments with 32 participants, PassNum achieved 98% accuracy with 10 s login time (average scores) and 100% memorability (cumulative scores). Furthermore, the 4th variation of PassNum proves to be 100% resilient against even recurring (3 repeated login sessions) recorded shoulder surfing attacks. Our qualitative survey revealed that PassNum might be the prime replacement for conventional PIN and password methods. pubtype: Academic Journal doctype: algorithm research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
