Your heart may soon be key to unlock phone

Your heart may soon be key to unlock phone [ad_1]

Scientists have developed a new computer security system that lets you log in with a heart scan - using the dimensions of the organ as a unique identifier.

The system uses low-level Doppler radar to measure your heart, and then continually monitors your heart to make sure no one else has stepped in to run your computer.

The system, developed by researchers at University at Buffalo (UB) in the US, is a safe and potentially more effective alternative to passwords and other
biometric
identifiers.

It may eventually be used for smartphones and at airport screening barricades, researchers said.

"We would like to use it for every computer because everyone needs privacy," said Wenyao Xu, assistant professor at UB.

The signal strength of the system's radar is much less than Wi-Fi, and therefore does not pose any health threat, Xu said.

7 'hidden features' of fingerprint scanners in your smartphone

7 'hidden features' of fingerprint scanners in your smartphone

Most new Android phones above Rs 10,000 have a fingerprint scanner now. You typically use it to unlock your phone but did you know that it can be configured for other functions as well? Here, we show you what more you can do with it

​Lock down apps selectively

Normally, you should protect access to your device with a fingerprint, passcode or pattern. But in some cases, there are multiple people using one device. In such a case, you may want to keep your Whatsapp, Photos, Calendar, Email Calendar, Email etc locked with a password while allowing access to other apps, games, YouTube and Google search. AppLock - Finger print Unlock (by Cheetah Mobile) is free and contains no ads. You can selectively choose which apps to lock. Even settings like WiFi, Bluetooth use, app installs and phone calls can be locked.

​Authenticate Google Play purchases

Free apps can be downloaded easily but when it comes to paid apps, Google will prompt you for your password -- just to make that it's actually you making the purchase. If no one else (read: no kids) handles your phone, you can make this step faster. Open Play Store and head to the Settings by tapping the three horizontal lines. Check the box that says 'fingerprint authentication'. If you have a stored fingerprint on the device, you can just place your finger to complete the transaction.

​Your private journal

Remember those old diaries with physical locks on the side? Journey (free with in-app purchases; by Two App Studio) is the app equivalent, secured with a passcode and fingerprint. You can make entries in your journal (up to 4 photos or 1 video per entry) and have them synced across your devices using the cloud (Journey is available for Android, Chrome desktop, cloud and on WindowsMAC). It looks great because it adds a lot of digital flourishes to your entries: weather, geo-tags and social sharing options.

​Showing selective photos from gallery

Don't you just hate it when you pass your phone to someone to show photo and they start swiping through all the images in your gallery? Caramel Apps, the makers of Solo Photo, feel your pain. You can select a bunch of photos (or just one) that you want to show and open them in Solo Photo. This will be locked with your fingerprint. Then you can safely hand over you phone knowing that your friend will only be able to view the photos you have allowed. The basic version is free, ad-supported and allows you some functionality. To unlock all the features (including the ability to select multiple photos at once), it costs $1.99.

​Keep passwords secure

It is a good habit to have different passwords for different accounts and that you can have password vaults on your device to protect access to these passwords. The password vault acts as a secure place to store all your passwords, protected by a single, master password. Well, if you use LastPass on Android, one of the leading password managers, you can also use your fingerprint as the master password as well as to enter passwords (autofill) on known sites.

​Fingerprints as gestures

An app called Fingerprint Gestures (free with in-app purchases; by SuperThomasLab) lets you use a stored finger print to initiate certain actions. This is a feature built in on Google Pixel but you can enable it on other devices too. You can use these gestures to launch an app, control music play back, activate the torch, change ringing modes, open notifications and so on. Some of the gestures will only work on Android 6.0 onwards. Your success with this may vary depending on your particular device. Some devices have large finger print sensors while others may have a narrow oval -- this seems to be the primary reason why the gestures work or fail.

​Fingerprint as a camera shutter

Some devices have this feature built into the stock camera app -- the ability to just tap the fingerprint sensor to capture a photo rather than tapping the screen. Look through the settings of the camera app. If not available, you can add it to any Android phone with Dactyl (Rs 130 as one-time purchase; by Nick Yelito). To make sure that it works well for you (there can be so many variations in Android hardware) the developer has a free trial version that gives you 10 uses to check with your favourite apps.

"We are living in a Wi-Fi surrounding environment every day, and the new system is as safe as those Wi-Fi devices. The reader is about five milliwatts, less than one per cent of the radiation from our smartphones," he said.


The system needs about eight seconds to scan a heart the first time, and thereafter the monitor can continuously recognise that heart.

The system, which was three years in the making, uses the geometry of the heart, its shape and size, and how it moves to make an identification.

"No two people with identical hearts have ever been found," Xu said.

People's hearts do not change shape, unless they suffer from serious heart disease, he said.

Heart-based
biometrics
systems have been used for almost a decade, primarily with electrodes measuring electrocardiogram signals.

However, no one has done a non-contact remote device to characterise our hearts' geometry traits for identification, he said.

The new system has several advantages over current
biometric
tools, like fingerprints and retinal scans, Xu said.

It is a passive, non-contact device, so users are not bothered with authenticating themselves whenever they log-in.



It also monitors users constantly. This means the computer will not operate if a different person is in front of it. Therefore, people do not have to remember to log-off when away from their computers.



Xu plans to miniaturise the system and have it installed onto the corners of computer keyboards. The system could also be used for user identification on cell phones.



For airport identification, a device could monitor a person up to 30 metres away.
