Researchers have developed a scanner that can identify and monitor a specific heart in order to increase device security.
Researchers have recently developed a new biometric tool that can be implemented to unlock devices. The scanner will be able to scan a user’s heart, focusing on the dimensions of the particular user’s heart to unlock the device.
A press release by the University of Buffalo stated that this new biometric tool will be the next step in cybersecurity. Like fingerprints and irises, there are no two people with identical hearts.
The system works by using a low-level Doppler radar. The radar identifies and continually monitors its user’s heart. This will add an extra layer of security as a locked device will be inaccessible by any person other than the user.
The researchers plan on presenting their latest findings at the International Conference on Mobile Computing and Communication (MobiCom) this October.
Right now, the researching team, led by Wenyao XU at the University of Buffalo’s Department of Computer Science and engineering, is working towards making the scanning device smaller and more condensed to easily implement inside smartphones, tablets, and computers.
This device will pose no health risks to the user, as the waves emanating from the scanner, are weaker than Wi-Fi waves. The Doppler scanner is even safer than being in a Wi-Fi area. According to Xu, the scanner emits 5 milliwatts of waves, which is less than 1% of the radiation coming from smartphones.
It takes the scanner approximately eight seconds to make a successful initial scan of the user’s heart. After the initial scan is made, the scanner continuously monitors the heart while the device is in use. The scanner uses the geometry of the heart as its guides, such as the heart shape, size, and its beating patterns. The shape of the heart never changes, which makes this an effective way of securing devices.
The research team has admitted that in a small number of cases, the shape of the heart may change in those enduring a serious heart disease. Though they have not yet developed a method for addressing this contingency.
The team is enthusiastic about this method’s success in the future, not only because a heart cannot be replicated, but also because it is contact-free, non-invasive, and remote.
The device will be able to monitor and scan a user’s heart from a distance of up until 30 meters away. The device also has the potential of being used for international security. Such as identifying and tracking people at airport security.
