Do facial recognition systems retrain themselves to compensate for change caused by growth or age?
- kyrra 8y agoRandom side-fact: a co-worker who climbs a lot stopped using fingerprint sensors on his phones because his prints change frequently enough due to climbing, that it's basically useless.
- baddox 8y agoMany years ago I had to clock in and out of a job with a fingerprint scanner. I had the same issue because I played acoustic guitar a lot and had thick calluses on my fingers that would occasionally crack.
- excalibur 8y ago> Many years ago I had to clock in and out of a job with a fingerprint scanner. Interesting, I don't think I've ever heard of a company doing this. Was it like a second factor in addition to some type of card reader?
- chc4 8y agoI've also had to do this. Worked at a fairly big healthcare company.
- baddox 8y agoIt was an entry-level IT support job at a US public school district circa 2005. They had just recently installed the scanners at every building. I believe that part-time and hourly employees like custodians, mechanics, groundskeepers, and cafeteria workers were the primary target, but the policy also extended to the tech support department (which was only me).
- mikestew 8y agoMandolin positions your finger such that the callouses form even further onto the fingerprint than with guitar. I gave up on TouchID with my left hand (thumb still worked, though), and FaceID was a nice upgrade.
- baddox 8y agoYeah, I believe at one point I had them rescan with my left thumbprint.
- hnick 8y agoI had continual issues ~20 years ago when I worked nightfill in a supermarket's perishable department. The freezer exposure apparently changed my prints enough that clocking out was an issue.
- kurtisc 8y agoLikewise for weightlifting hook-grip, which squashes your thumbs against the bar's knurling.
- LeftTurnSignal 8y agoI mostly stopped using mine because I have a bad case of hyperhydrosis (sp?), so my fingers are always sweaty / oily enough that none of the devices I use can reliably tell what my prints are. Even when I got printed for the feds (for work reasons), they had to redo most of the fingers.
- jfoutz 8y agoUse a knuckle. I have a similar problem. Works ok.
- takk309 8y agoI climb regularly and can say that I am a bit concerned that the finger print scanner on my Pixel 2 works as often as it does. It makes me wonder if the initial scan of an abused finger means that it will read false positives more often.
- Wowfunhappy 8y agoApple claims their FaceID system does, at least.
- trothamel 8y agoGoogle Photos was able to determine that pictures of my niece as an infant, and pictures of my niece as a 5 year old, are pictures of the same person.
- sigmar 8y agoI've noticed this competency in google photos as well. Though surely it is using the photos of her in between those ages to extrapolate(?)
- Kipters 8y agoAnecdata: I regularly grow a beard and then cut it fully. Windows Hello on my Surface Pro works flawlessy during the growth phase, but it stops working when I cut it off. I guess it adjusts while my beard grows and then it can't recognize me anymore once I don't have it anymore all of a sudden.
