Ultrasonic Fingerprint Scanners: How do they work?

2016-02-17
this episode is brought to you by domain.com do you ever have that nightmare where someone cuts off your thumb uses it to get into your phone and then has access to your clash of Clan gems while qualcomm feels your pain let's take a look at Qualcomm sense ID ultrasonic fingerprint scanner and see how this technology works and what sort of advantages it has to offer over current fingerprint scanning technologies on the market to actually capture the details of a fingerprint the hardware consists of both a transmitter and a receiver an ultrasonic pulse is transmitted against the finger that is placed over the scanner some of this pulse is absorbed and some of it is bounced back to the sensor depending on the ridges pores and other details that are unique to each fingerprint there isn't a microphone listening for returning signals instead there's a sensor that can detect mechanical stress that is used to calculate the intensity of returning ultrasonic pulses at different points on the scanner scanning for longer periods of time allows for additional depth data to be captured resulting in a highly detailed of 3d reproduction of the scanned fingerprint now this is considerably different even the best capacitative fingerprint scanners on the market at the moment which are only able to reproduce 2d images 3d details are much more difficult to forge or fool than 2d versions of the technology potentially making the ultrasonic system much more secure another added perk of this technology is that it allows the fingerprint scanner to still operate through thin materials such as a smartphone case built from glass aluminum or plastic therefore the scanner can be embedded under the case allowing for a more discreet look now when it comes to security Qualcomm secure MSM architecture in its Snapdragon processor provides additional protection by a separate execution environment that is kept away from the rest of the high-level operating system secure MSM is traditionally used to handle cryptographic and other sensitive bits of data this way important user security information is kept secure on its own piece of hardware and in a separate software bubble away from potential malicious bits of code Qualcomm sense ID also supports Fido or fast identity online Alliance protocols which can be used for online password less authentication without transferring any of the confidential fingerprint information to the cloud or through networks that can be compromised now to unpack that for you that just means you'd be able to log into certain apps or websites by simply using your fingerprint scanner and not having to type in your password with your two little thumbs pretty cool this is very geeky but very exciting it allows us to make our devices much more secure I hope Qualcomm can market this in an effective way just say that it's way more secure than first generation fingerprint scanners instead of going into all the techy details what do you guys think would that be a distinguishing feature for you to buy a phone if it had you know Qualcomm sense ID would be for me what do you guys think let me know in the comments below so do you guys remember from like 15 years ago when people were making money hand over fist in the dot-com bubble remember we didn't call it a dotnet bubble or dot org bubble we didn't call them dot biz billionaires we called them dot-com billionaires because that's the power of a dot-com now why is that because no domain name extension tells your story with the same degree of trust as a dot-com or dotnet domain name.com and dotnet domain name extensions and jet credibility into your online presence save fifteen percent on domain names and web hosting when you use our coupon code android at domain.com check out when you think domain names think domain.com thanks for watching edward army my name is Jace just a quick reminder that yes I still am taking uh you know thanks for watching Edward army my name is Jace I'm still sick I know forgive the voice but I wanted to say that I still am taking domain name suggestions via Twitter or in the comments below Twitter's usually best because I follow that all the time and I will announce that at the next domain.com show alright good stuff don't want to forget about my brothers and sister and Android who are working super hard to be your source for all things Android
