This is what I want...
- A human walks up to a place which requires previous approval to get in the building.
- The human claims to be Samuel SpecificGuy
- The human places his two hands on two pieces of glass
- Two scanners take a look at them
- Software compares these two scans with previous scans of his hands which are on file
- The software indicates the level of confidence that this really is Samuel SpecificGuy
This can't be a brand new idea. I mean, really; checking hand size to help guess if the guy is an impostor ? I've seen the same at least once, without a human; just software granting access to places with pretty important security restrictions.
I'm NOT talking about fingerprints !!! Just hand size.
I asked google and bing for something about hand scanners and I got a bunch of hits about bar code readers.
Could somebody provide me with a vocabulary lesson as to what I should ask, e.g., phrases that google or bing might understand ?

Try palm scanner?
Probably get a lot of results about palmprint scanning though.
|
|
|
|

How about a combined face palm scanner?

After a short search I've found something that can help you, I guess you'll be able to get the source code somehow:

Good luck!

I've designed and created something similar. Rather than putting the palm on glass panels I give authenticated users a device that is placed in the palm instead and the device grants the user the required access. I call it a "key".

With the first sentence you raised my hopes for the one scanner I always was waiting for. Imagine lowering your pants and sitting on the scanner until it has verified your identity, the whole time surrounded by security guards.
For some reason this always must be a lengthy and complicated procedure with bonus points for being embarrassing or involving being groped all over by strangers.

Facial recognition and gait analysis are sufficiently advanced that you should be able to verify Samuel Specificguy before he gets to the door using already installed security cameras.

I'm with DEJ facial existing recognition stuff alone should get you a reasonably high level of confidence for most requirements.
Bloody hell a local restaurant has the dammed thing set up so the waiter can greet you by name and knows you purchase history.

Why in the world would you want that? You may as well ask them to guess a number between 1 and 4. It will be just as accurate determining if it is the right person or not.
There are two kinds of people in the world: those who can extrapolate from incomplete data.
There are only 10 types of people in the world, those who understand binary and those who don't.

I don't think hand-size would be unique.
And how hard the person presses on the scanners would change readings too easily.

Google "hand size" scanner. Note the quotes. Several links down, you find this. Not related to security, and probably more than what you're looking for, but might give some guidance on other phrases to try, like "hand measurement."

Excellent ! Thank you Marc

What if Samuel had gotten stung by a bee on a finger one evening and the next morning that hand was swollen? That hand wouldn't match would it? Or some other injury to the hand causing it to swell.

Does this include a robot armed with a bottle of glass cleaner so that each time it is used it can be sanitized again?
Ohhh...you know what? You could identify the person based upon the unique bacteria on their hands.

OK, here's my situation. I have a dir that has a bunch of subdirs & files at various levels of nesting on a pair of drives. My goal is to have both be the union of the original set of stuff so that they have exact same contents.
Using the Properties dialog for the 2 drives, both as directly selecting the top node dir folder icon, and as going into the dir and searching for *.*, then selecting the all the files I get for the # of files & dirs:
C: via *.* -> 3826 in 616
H: via *.* -> 3826 in 616
C: via top folder -> 3824 in 616
H: via top folder -> 3819 in 613
If I open the top dir and select all the items (which are all dirs), the value is the same as if I had selected the top folder.
Going into the CMD window and doing dir *.* /w /s (or whatever) gives the same size as per the *.* selection, although for whatever reason, it shows 3X the # of dirs. 
So the good news it that everything seems to be copied (the total size is also the same) properly. However, I like to use the Properties dialog to do a quick check of the # of files, dir & size to make sure that a copy has been done properly. Here, the copy has been done properly, but it still does not show when accessing the Properties via the folder icon, and thus doing this check will involve a big PITA to get something that should be simple. 
I have no idea how to fix this!

I seldom ask for this sort of stuff on CP, but today I find myself wishing to proposition the good will of all that is CP and its CPians.
Turns out I got a phone call from a talent acquisition manager at NBC Universal moments ago and they're looking for a role that's perfect for me, which is to work directly with the business sponsors to help build up a new project in the TV Development department. This is something I did at Live Nation, so this would be an awesome job for me because A: I can continue the growth in my career I started at Live Nation B: it's freaking NBC and C: it's literally like one mile away from where I live so I'd have no lengthy commute.
What I would require is for all those who believe, is to keep the positive juju alive and put it out there in the great ether that is the universe that I should get this job. Believe it with me.
And if so, I promise to never, ever, ever again say anything good about JavaScript again to Marc (well for at least a day or two). I also promise to say nothing but delightful accolades in regards to VB.NET to Chris (for at least a day or two). And of course for Gary, I'll go so far as to say bicycles are better than motorcycles (for an hour or two). And well, I don't really know OriginalGriff, but as a bonus I'll go upvote his articles or something.
Positive vibes... positive juju... let's put it out there folks.
