Iris scanning the safest biometrics solution on phones, coming soon to midrangers


Leave it to the company that just unveiled an Android flagship with iris scanning authentication to try and explain how this is the safest personal ID method that can realistically be put in phones for now. Samsung has done a meeting yesterday, extolling the virtues of the iris scanner that it put in the Galaxy Note 7 as the most secure identification method this side of actual DNA analysis.

Seriously, Samsung has thrown in that exact argument: “Mucus and blood from inside a mouth need to be collected to obtain information about one’s DNA,” according to Kim Hyeong-seok of Samsung Electronics’ Wireless Business Department’s Development Room. “Because it takes more than an hour to analyze this information, it is realistically impossible to use DNA information on portable devices.”

Apparently, that is why the company chose to go the way of the iris scanner as an extra biometric identification method - there is one in a billion chance it will be the same on another person, and the pattern disappears right after death (oops, what about alien abduction). The scan is then scrambled and stored in the trusted zone of the ARM processor, from where it is matched each time you want to unlock your phone with your gaze, and not going to any servers, so it is as secure as iris or finger scanners get on phones.

Funny enough, just while Samsung equipped its Note 7 with a dedicated iris scanning camera and near-infrared LED emitter, that same setup has now been combined in one for the front-facing camera of future handsets by another Korean company, Dongwoon Anatech. They announced the development of a technology that incorporates a filter in the selfie snapper that can be actuated for near-IR light emission, then taken away when you need a photo. This combining of two modules will lower costs and free up space inside phones, so the company is "working on design with South Korean and foreign сmartphone camera module manufacturers" to equip even midrange models with iris scanning authentication.

Samsung's patience and investments in R&Ds is paying back... the only breakthrough really left is on phone batteries....

Nah, Touchwiz lag on the Note 7 needs immediate attention from Samsung. XD

I'm guessing that they aren't going to fix that jank in this version of TouchWiz and have just shifted effort to their Nougat version. That is likely why it is a mess because why expend resources with something they have to update within a month of release.

No. Only you lag of ideas and reality.

Mobile batteries are improving every year and components are getting more and more efficient. The reason we are not seeing real life advantages is because android is getting worse every year at battery management, making up for all the improvements, and then some with google play services and android system drain. On to apple side, they are making devices thinner with less battery. So that's preventing battery life gains there. If you don't believe me, look at laptops. They have literally doubled to tripled their battery life in last 5 years.

Let me stop you there Reason why laptops have improved so drastically in battery life is largely due to the fact that processors weren't focused on power usage before. There was no real need/demand for power efficiency prior to all of these mobile devices taking a chunk out of the overall portable devices share

That's part of the reason. But mobile phones could have done that too.

Mobile phones have been more efficient then laptops.

10. sarcastic_nerd unregistered

Duh, everyone knows that. But they didn't change their efficiency in last 5 years for phones. Manufacturers just want the biggest numbers on the benchmark charts instead of undervolting high end chips to get more battery life out of them. A snapdragon 820 at 1.7 GHz will consume roughly half the power while not being much slower to affect fluidity. Yet no manufacturer has even tried to do that. We don't need faster chips, we need more efficient ones. If only, the peak power consumption has only grown over the years for phones, often exceeding the TDP limits and then throttling to avoid overheating while consuming a lot of power in the process. We both know that mobile battery scene is pathetic at best. But it isn't due to no improvement in battery technology. If manufacturers want, they can optimize their software and undervolt their chips to provide excellent battery life out of their phones. But no one is even trying.

I don't know your intentions but your information is ridiculously wrong. Android hardware and software is literally the most efficient it has ever been and likely far ahead of their competition. Every chip currently in use undervolts when not being used 100%. Power management at a per core level has been in all mobile phone for the last few years. The problem is the screen and resolution. The vast majority of battery drain comes from the screen. The Apple koolaid suggests that Apple is more efficient because of iOS but it isn't. It is more "efficient" because it has a low resolution screen. The obvious example for that is that Apple devices usually have a lower battery life compared to other devices of higher specs but same battery capacity. For example: Galaxy S7 Edge has a 20% larger battery and gets about 10% better battery life than the iPhone 6s Plus. But that is with 2x the resolution of the iPhone 6s Plus. http://www.anandtech.com/show/10196/the-samsung-galaxy-s7-and-s7-edge-review-part-2 Your original assertion that laptops have been improving in battery life is also wrong. The resolution on most modern laptops are lower than current gen smartphones and they also have a lower brightness in almost every case. Those are the two main power drains in any device with a screen and therefore, smartphones are leagues ahead of laptops and likely will remain that way.

BS. iPhones consume almost no power in stand-by while android phones have android system/google play services at second or 3rd spot in battery consumption. Also the battery drain is 1-2% per hour in standby on most android phones. Android standby consumption has risen steadily with each version and is at the worst currently. Also I'm hearing complaints on 7.0 consuming ridiculous amount of battery in standby through background processes. So yes, it's getting worse now too. The anandtech test completely ignores the standby time which is an integral part of battery usage. Yes, they undervolt while not in use. But the peak power consumption is way higher than it should be. Laptops can maintain their peak performance but current smartphones cannot. Not to mention how the battery life of current flagships tank while under heavy CPU usage. Also how badly they throttle. I'm mainly unhappy about 2 things: 1. Standby drain getting worse on android: I mentioned it very clearly the first time. But you probably are too thick to understand. Yes, android is much more efficient now 'under use' as it should be. I'm talking about the standby consumption though and not usage when screen is active. I remember the old days when my S4 would barely consume 1% every 3-4 hours on standby. Try to duplicate that standby performance on any android phone in 2016. While iOS devices can easily achieve that. 2. Over-achieving processors: As I said, most CPUs consume too much power than they should on smartphones, especially the flagship SoCs. That's mostly because they are clocked higher to achieve higher benchmark numbers instead of being optimized for battery. There should be no reason for a mobile SoC to have a power envelope of 5W. That would drain a normal sized battery(3000 mAh, 3.7V) in under 2.5 hours. They should be underclocked and undervolted at their peak. For example, a Snapdragon 820 should have been a 1.7 GHz processor, and not a 2.2 GHz. It consumes way too much power at load compared to other chips. I guess I made myself perfectly clear here.

1) I haven't lost more than 3% on my Z5 compact over 8-9 hours overnight. That is with LTE, bluetooth and NFC on. My Nexus 7 loses about 4-5% but I'm pretty sure that is because of its battery age rather than the OS. I don't know what devices you are using, but it likely has to do with the downloaded bloat you've got on it rather than the OS itself. 2) Qualcomm processors are fairly hot running, battery eating pieces of crap but that is the only option anyone has. That has more to do with the broken patent system than anything else, but nothing you can do about that.

19. sarcastic_nerd unregistered

Not talking about overnight drain. That's pretty low since doze runs. I'm talking about drain in 2-3 hours standby when the phone is in your pocket and you're walking about. P.S. : 3% overnight is pretty bad drain. iPhones usually lose less than 1% overnight and my oneplus 3 does the same. 2. Agree on that part.

double or tripled for netbook and convertible.. since battery eat most of its internal space, and they use power efficient (low performance) hardware.. if you look at $400-$600 normal i5 laptops, battery life didnt change that much on the last 5years, its just become more power efficient thanks to newer gen of processor.. battery size didnt change that much check Wh size of 6-cells battery for 5 years ago, compare it to newer 6-cells... battery improvement is more obvious on smartphone.. 7mm smartphone nowadays can fit 4000mAh battery, while 5 years ago 10mm smartphone only have 2000mAh (or even less)

I have had a lot of people asking me if my phone is the note 7 these days. I'm using the lumia 950XL as my main phone. Have had iris scan for over a year. People were always fascinated but now they are associating it with Note 7 haha.

950/xl says hello from a year ago and showed how iris was more secure since last year, you're welcome

Saliva reader? Nah, takes too long to identify. Kinda gross too if you keep spitting on your phone.

Even then the Iris scanner is still hit or miss with scanning (forgot which review stated had this issue) but it will definitely improve in future implementations.

did they really consider using DNA to unlock if it were fast enough? how did you unlock your phone? spit on it? or kill the owner and drop some of his blood on it? (sounds like some weird ritual)
