LG Announces G8 ThinQ Smartphone That Uses 'Advanced Palm Vein Authentication' Tech To Unlock (techcrunch.com)

LG's flagship G8 smartphone has been officially launched today, bringing many expected features that were teased over the past few months and several not-so-expected features. One such unusual feature in the G8 is its palm vein recognition, dubbed Hand ID, which LG claims is the first to offer this capability. TechCrunch reports: From the company's press materials, "LG's Hand ID identifies owners by recognizing the shape, thickness and other individual characteristics of the veins in the palms of their hands." It turns out, like faces and fingerprints, everyone's got a unique set of hand veins, so once registered, you can just however your hot blue blood tubes over the handset to quickly unlock in a few seconds. The Z camera also does depth-sensing face unlock that's a lot harder to spoof than the kind found on other Android handsets. LG's also put the tech to use for a set of Air Motion gestures, which allow for hands-free interaction with various apps like the camera (selfies) and music (volume control). Other features of the G8 include a 6.1-inch QHD+ "Crystal Sound OLED" display that uses the screen as an audio amplifier. There's a Snapdragon 855 processor with 6GB of RAM and 128GB internal storage, three cameras on the rear including a 16-megapixel Super Wide (F1.9), 12-megapixel Standard (F1.5), and 12-megapixel Telephoto (F2.4), a 3,500mAh battery that charges via USB-C, a headphone jack, and 32-bit Hi-Fi Quad DAC.

      I think amplifier could be perfectly acceptable use of the word here. The transducer is what would be acting on the back of the screen, and the shape of the screen amplifies the air pressure waves which would otherwise be tiny without the available surface area, but would none the less still be air pressure waves.

      The screen only acts as a transducer for calls. Basically a bone conduction system that makes it easier to hear the other person in a noisy environment. It can't be used as a speaker.

      So with your logic, for a loudspeaker, the motor (magnet circuit and voice coil) is the transducer, and the cone is the amplifier. Nope, not gonna let that one slide... A transducer in this case is what changes electrical energy into pressure - and that includes the radiating surface (since the pressure generated is proportional to the radiating surface, and the radiating surface is required for the transformation to take place).

      Yes, it could be used as a speaker. Even microphones can be used as speakers (albeit they suck), and a bone conduction transducer IS a speaker as well. Additionally, since SPL is proportional to displacement, and a screen is huge compared to a typical 6mm x 15mm speaker in a phone, you'd need precious little motion on that large area to get usable SPL output. A typical microspeaker has around 1.5mm - MAYBE 2mm - of maximum excursion. This screen has about 120 times the surface area, so you could have the same SPL level with around 16 microns of motion. LG may choose not to use it as a speaker - but it would actually be a pretty decent one, if the story is accurate that the entire screen moves...

      What I'm saying is it COULD be used right now - there is nothing physically limiting it from working that way. Your claim that it could not be used as a speaker is wrong; it's a choice LG has made right now, there is no physical reason it could not be used, given the level of excursion required to replace a traditional speaker.

      the motor (magnet circuit and voice coil) is the transducer

      definitely.

      and the cone is the amplifier

      arguably.

      Cut the cone out of an old loudspeaker. Notice it still makes sound but at a greatly reduced volume and efficiency?

      in this case is what changes electrical energy into pressure

      Like the the magnetic coil that applies the force to make something move?

      and that includes the radiating surface

      That is your own definition. In fact I can't find the radiating surface mentioned in Wikipedia or in my textbook.

      since the pressure generated is proportional to the radiating surface

      So you're saying a bigger radiating surface would "amplify" the pressure?

      and the radiating surface is required for the transformation to take place

      Again hold up one of those surface transducers in the air and hear that wonderful transformation having already taken place. Likewise cut the cone out of a speaker (but you need to point the speaker vertically) and listen to that transformation still making sound.

      The word transducer doesn't include mention of volume or quality in its definition which makes it independent of its radiating surface. The word amplifier on the other hand ... well you get the point.

      Nobody is forcing you to use biometric authentication. You always need to set a password lock on your device if it fails to recognize you anyways. A lot of people "protect" their devices with such terrible passwords (I can see someone making an L or a square to unlock their phones without even meaning to) that biometric authentication turns out to be safer that what they're currently doing. My opinion is that, although in theory biometric authentication is weaker than a strong password, it protects you more effectively against theft (the most frequent attack vector in my opinion) than a password. A thief may be able to infer you password by looking at you type it; he may even record you with his cellphone while you're unlocking your own for when he gets a chance to steal your device. It's not likely though that he will be able to make a convincing fingerprint or even take a good enough picture of your face to fool some primitive face recognition technique which is frequent on some Android devices.

      Biometrics are a massive security win for most people. You simply don't understand the threat model most people face: Laziness and imperfect human memory.

      Having a decent password is obviously best, but also annoying to have to type it in every time, vulnerable to shoulder surfing when used in public, and the more secure it is the easier it is to forget. Most people re-use their passwords too.

      So for the majority of customers the choice is between no security, crap security like a short PIN number or unlock pattern (vulnerable to observation and smudge detection), or relatively difficult to bypass biometrics. Sure, a determined attacker could clone your fingerprints with sufficient fidelity to fool the sensor, but given that even the police don't seem to be able to do that I doubt it's much of a concern for most people.

      Face unlock is probably the worst, if you are worried about your partner using it on you while asleep, but a lot of people know their partner's passcode anyway.
