'One reason was that palm recognition is considered more private than some biometric alternatives because you can’t determine a person’s identity by looking at an image of their palm.'
Umm, if this is true, how are you identifying the person then?
- brian_herman 6y agoYeah, I was confused at this statement too.
- n_t 6y agoI think they are saying that humans cannot associate palm prints to an individual, unlike face (or even eyes in certain cases). It's just security by obscurity kind of thing but yes, not very convincing argument for privacy.
- strawberrypuree 6y agoThis is a sleight of hand on Amazon's part. Humans looking at a palm print and identifying the person is not a concern, it's computers looking at a palm, associating it with a credit card, which can then open up a trove of behavioral data to push (i.e., ads) to people. It's disingenuous, like putting someone in a tiger cage and saying "Don't worry, there's no way you can drown in here -- we made sure there's no water."
- BerislavLopac 6y agoMy guess is that they meant that a person couldn't determine someone's identity, unlike with, say, facial recognition.
- IshKebab 6y agoPerhaps using some electrical or acoustic properties? They're very cagey about how it works, so I doubt it is just a camera. > Q: What is the device actually scanning when it creates my unique palm signature? > > A: the technology evaluates multiple aspects of your palm Ok then.
- hughw 6y agoThey don't identify you. They read your future.
- jacobr1 6y agoI think it means that they are using some 3d representation of a palm that a (single) 2d image won't capture (unlike a fingerprint). Maybe they use video (gesture was mentioned) or maybe something like lidar.
- smhost 6y agoWe should read the opposite of what they're saying to be true: they already have our fingerprints, and they want the rest of our hands.
- giancarlostoro 6y agoHate to go that way but I was thinking this. What's worse is that it is uploaded to some server somewhere instead of being kept localized.
- ragona 6y agoMy hope and suspicion is that they’re storing a one way hash of the data to create the signature.
- losteric 6y agoThe camera is just one of many signals, some of which do change over time
- nerdjon 6y agoThe wording of that is odd. But my guess is, your face could be identified wether or not you are using this particular system. But your palm only works after the system does the scan of you so you have to specifically opt in to use it.
- julianozen 6y agoIs it possible they are saying that you can’t uniquely identify a person in the population at large based on palm, but you can in a smaller population of people such as registered Amazon go users or ticket holders for a venue? On an iPhone, biometric is being treated as a password where the expectation is that no one but you could open it. For Amazon go, it is just an identifier to a user Plus a data dump of uuids and palms might not be useful information. Maybe there is a effectively a way to hash the raw palm data since this is just effectively a user look up This is pure speculation
- mister_hn 6y agohere's a famous video on how it can be hacked easily (example: Fujitsu PalmSecure) https://www.youtube.com/watch?v=FsZE6fyF26U https://www.youtube.com/watch?v=FsZE6fyF26U
