At the time of ASCII terminals and command line interfaces, passwords made sense. Nowadays, however, the main online interface is a graphically rich mobile device. So why are we stuck to alphanumeric passwords? This is the question asked by Ilesanmi Olade in "SemanticLock: an authentication method for mobile devices", which only uses semantically related images. Instead of organizing an arbitrary alphanumeric character string, you can start with a group of images from which to select a few that tell you a meaningful and memorable story. Listening can be simple, like "Drink a coffee at breakfast". So when you unlock the phone or website, you can choose from a group of graphic icons to tell you the story.
The big screens of today can accommodate up to 12 to 20 icons. As the icons are used, other pictograms can take their place, increasing the number of possible combinations. Most SemanticLock techniques are based on models. Users move their finger on a network in a template that they have created. Model-based authentication is faster than PIN authentication, but vulnerable to attack, where the fingerprint on the screen can reveal the location.
The researchers tested SemanticLock against authentication and PIN models. They found that while the templates provide the fastest authentication and the lowest error codes, memorizing stories from SemanticLock is superior, with only 10% of participants not remembering their password. other authentication methods. Researchers have been exploring graphical passwords for over a decade. What is new in the approach of this work is the emphasis on memorability through stories that appeal to human love for narrative. This study highlights the importance of industrial work with fingerprint recognition and facial recognition
