Touch screens that recognize the user

Touch screens that recognize the user

Today touchscreens are present in many applications of our day to day; tablets, smartphones, POS terminals, GPS devices or even computers have many cars touch interfaces. While it is possible to establish tactile patterns (very popular in Android) or passwords on our mobile devices to prevent use by others, there are many projects seeking to implement new measures in these devices. In the case of Rutgers University (located in the State of New Jersey), a research team has long been working on a system that can identify the user of a touch device using a ring that acts as a key.

The project, carried out by a team of eight researchers, aims to identify the users while they interact with capacitive touch screens using an electrical signal and a device trasnceptor (materialized in a ring that acts as a “key “) positioned on one of the user’s fingers. A ring on the finger of the user? Basically, the scheme is not too far removed from a coded key (as used by many cars today) because without that ring can not access the device but, in this case, to have the ring will not be enough because it will generate an electrical signal (voltage not much) that will air on our skin and serve to activate the capacitive touch device.

Put another way, the ring generates a control signal that passes through your finger and combining both, the capacitive screen will respond by identifying the user (or the opposite). The idea is quite interesting because it opens the door, on the one hand, to a new level of security in tablets and smartphones (think applications with high safety requirements) and, on the other hand, it also opens the door to the development of multi-user devices, this ensures isolation between biometric pattern profiles and therefore the data privacy.

For now, the device is in an experimental stage and have developed a working prototype with which team members can authenticate on a terminal but maybe in the future, could be used to adjust the settings of each user terminal that usase ( identifying by this method):

Imagine you knew any electronic device and adapted to your preferences or customized information offered you simply identifying who you are

The team hopes that the resulting prototype into a commercial product within a couple of years ago but have to work on miniaturizing the token (the ring) and the design and aesthetics (because now is a prototype made in a little plate or anything showy).

An interesting way to protect the privacy of users.
