One thing that bugs me about fingerprint reader is that why don't they make it like a password? With 20 fingerprint (10 hands + 10 legs), you have 20 possible answer to unlock your device. But with combination of n "character", you have 20^n, much harder to break like your password is harder to break the longer they are.
Oh right, that would be great! That way there's no risk of people cutting your hand to open your safe
the question is, does that make any difference from using a password+fingerprint or password only? the numbers of tap you need in the end will be the same. and the reason why we use fingerprint is to make more convenient than remembering the password.
But is that actually secure? If I remembered right, there are ways to fool them. Does using fingerprint + cellotape to open fingerprint lock still work? it's real? you have 1/20 chance of using someone's finger to open their fingerprint lock right now. If you use 2 fingerprint combination, that's 1/400. 3 -> 1/8000.
but i still dont understand, what happen if you hurt your fingerprint?(ex: burned) you can't open the password?
Chances are that if the person is desperate enough to fake your fingerprint to take something from you it must be very valuable
doesn't matter if its a combination or not. imagine using 10 images to input as your password. Also imagine the time it would take for you to input 10 fingerprints and figuring out the difference if this is a new fingerprint or the same one a second ago. In short it may take more time than more practical methods making it impractical for phones in general when you just want to open your phone to watch youtube.
10 fingers* and 10 toes* I cannot imagine someone with that many hands and legs as well. As for the idea, I would prefer you just stick to the 10 fingers instead.
It's same as asking, why not use 20 key locks for your door when it'd be more secure I'm pretty sure that if someone were inventive enough to get your fingerprint, they surely would be able to get in your phone anyway, unless it's some super important thing, and for those cases people generally have many better and more expensive ways to secure stuff.
Not that many actually. Phones are often used one handed, plus using many fingers will increase the chances of dropping the phone. Apple, which is a trendsetter, also moved quickly up the tech ladder to facial recognition, which has many potential clients.
I mean, first off all, multiple finger/toe prints are going to take more time to process, both the scan and verification in the software. Then you have to consider the hygiene of using your feet as well as the hassle of removing shoes and socks to use them. A potential issue I can see is having to remember a chain of prints if you want to use them in sequence as you would a password, although you could argue you might not need that given how unique prints are, and it's just a matter of having the prints present and not necessarily in the correct order presented. I'm also not particularly worried about losing your prints to injuries, at least sanding or acid will have your fingerprints regrow in about 10 days anyways. I've no idea about the time frame for burns since you are going to be replacing more than a few layers of skin most likely. All of this could be circumvented by say using all 10 prints, but only needing 3 or 4 to unlock a device, since you are unlikely to have all prints removed. At an end note, I'm not particularly sure what the grand purpose of having a need for multiple prints would be, at least for individuals who aren't hiding anything of importance on a national scale. You will always be threading a line between convenience, accessibility, and security.
Sure! Soon tablets would be "in" & people would carry them all i/o handphones Just think for a moment 'bout how big a human palm (or foot) is if you even want to use 5 fingers id Might as well goes for a palm print id instead
depend from the fingerprint sensor are you using. here the link for more info if you are curious about them: https://www.arrow.com/en/research-a... optical scanner,the user's own personal code.
It would say, “fuck you” I have a deep scar on my left thumb and that part of my thumb doesn’t have its fingerprint part anymore. Whenever I have to get printed or scanned, the machine or person administering it get confused and I usually get questioned and then have to show them my thumb before they okay the scan. So yeah, if something is wrong with your finger, a normal scanner probably won’t take it.
