Veri-Pen is an alternative digital identification device that delivers identification through combination of fingerprint data and signature.
Most of the online identification systems relies on an ID - password combination, with variables including minimal string length, capitalization, numbers and non-alphanumeric characters. There exist two central axes in the functionality of such digital identification: secureness and simplicity. These two values are most often inversely proportional. A highly secure identification system utilizes a large set of variables, which sacrifices usability and simplicity. While this is true, biometric identification can be simple method of identification.
The user evaluation included a qualitative evaluation of the identification experience of Veri-Pen.I asked the participants to plot where Veri-Pen would lie along the Cartesian map of the axes.
The premise was that the participants would feel online authentication through the pen device to be safer and easier than the conventional ID - password method or other types of identification.
All participants found this system to be more secure than complex password combinations, while maintaining its simplicity. All participants agreed that the design of Veri-Pen was intuitive and use of biometrics seems more secure than passwords. One participant commented that, “it felt like signing on a digital receipt.” Another participant commented, “I sign regularly, so I think the pen based identification seems intuitive for people with distinct handwriting.”
