Since now many people don’t trust the traditional passwords, some technology companies began to explore other ways to ensure people’s online account safety. Some companies invented to use brain waves or fingerprints as passwords. Now there’s a new encryption method in the world.
A wristband called Nymi can detect user’s heart rate through ECG sensor, and allows user to use own heartbeat to decrypt device. This product can be used with iPad or even cars. This product manufacturer is Bionym from Toronto, the company’s developers said using human heartbeat to unlock the device is safer than using fingerprints, facial recognition and other external means to do that.
When first time getting the device, users simply need to use finger to press on the sensor of the wristband, the sensor will automatically monitor and store the user’s heart rate. The whole process takes about two minutes, after saving the user’s heartbeat, the device will only recognize the user’s heartbeat. Ordinarily, the sizes of people’s hearts are completely different, so produced electrocardiogram is unique.
Daily use of the device is also very simple, you need to press and hold the sensor with your finger, after a few seconds, the sensor will be able to identify the user’s heart rate, and use Bluetooth technology to connected with the device that need to be controlled to unlock the device. When wristband leaves outside of the scope of Bluetooth, the device automatically locks.
Nymi even works with the gesture control feature, for example, when a user is in the car, waving can open the drive side door or rotating the wrist to open the front passenger side door. In addition, the product also has a secure payment feature, at highway toll stations users can use it to scan the device charges, and the fees will be automatically deducted from the user’s account. The wristbands can also remind users of receiving a mail or social network message by vibration, while the device vibrates, the screen will also display.
This encryption method is limited used to protect devices. We now still use traditional password most. For example, we use traditional password to protect files/folders on computer or external hard drive.
