Computers can recognise our faces, fingerprints and retinas. But soon software could also know our heartbeats too, and use them as a way of locking our tech gadgets.
Chun-Liang Lin, a scientist at the National Chung Hsing University in Taiwan, has created a prototype that can use your heartbeat to unlock a technological device. It works using a technique similar to a electrocardiograph (ECG) that measures the electrical activity of a person's heart. Lin used this in conjunction with a method of encryption, meaning the system can recognise an individual's heartbeat. He then placed this technology into a device that can recognise a specific person just from the pulse in their hand. In other words, if the technology were put into a personal tech device such as a mobile phone, a person would only need to touch it with their hand to unlock it.
The death of the desktop can't be far away as computers shrink into smartphones and tablets. As a result, passwords may also soon no longer exist. For instance, Apple's new iPhone is rumoured to have facial recognition as a means of unlocking the device. Seeing as the touch-based nature of those devices is what sets them apart, heartbeat encryption data seems a more fitting way to keep your data safe and private.
