India: How breathing could unlock your phone

DW (English)

Researchers at an Indian university are working on innovative technology that could become one of the safest biometric authentication systems. And it could end up have other uses, too.

00:18 My research work is on human exhaled breath.

00:22 We study how unique the breathing is for each person.

00:27 We use a fingerprint or face recognition system.

00:31 This is a breath based biometric system.

00:34 The technology we have built is based on the flow of human exhaled air.

00:50 We can call it a breath fingerprint.

00:55 A unique difference with this biometric system is that

00:59 compared to other eye-raise based, fingerprint or face recognition based systems,

01:06 a dead person cannot unlock this biometric system.

01:12 The person has to exhale.

01:14 Only if the person exhales voluntarily, the biometric system will open.

01:36 What we see is highly constricted, medium constricted, dilated.

01:42 We started with the idea that it is enough to identify three types of individuals.

01:48 Now we have 100 individuals who are classified individually.

01:53 In user confirmation.

02:07 A big problem in medicine is that there is no personalized medicine.

02:11 If you take dolopar, everyone will get the same amount.

02:14 But everyone does not need the same amount.

02:16 But it is difficult to size dolopar for everyone.

02:19 That is why it is standardized.

02:21 So personalized medicine is going to come in a big way.

02:25 When it comes like that, using this technique,

02:27 you can find out your internal structure,

02:29 what device to use, what amount to give.

02:32 If you start thinking about all that, the applications will become more and more.

02:35 [Music]

02:48 Our research is still in the preliminary stage.

02:51 If we look over time, a person's breath can change or not change.

02:57 So further studies are needed to understand that.

03:00 That is why we are working now.
