So a modern thumb drive is 1 Terabyte (1e12 b=Bytes) and I read on the internet that a typical thumb print is 10KB (https://www.govtech.com/security/Biometrics-Needed-.html), which is 1e4 Bytes. So that is 1e8 thumb prints, or 100 million. Your follow-on link says there are 10 million finger prints in the FBIs database (perhaps all in that photo), so in fact a modern thumb drive could store 10s times as many finger prints as in the photo, and a smart phone could probably find a matching fingerprint as quickly as Google can search the Internet.
Where is the building? When was it built, and was it built for this purpose? Does it still stand?
ReplyDeleteHere, let me Google that for you...

Good website. I've added it to the body of the post.
:-)
The "rare historical photos" on that site are often mislabeled. I would always do a deep Google Image Search on anything you find there.
DeleteMy glass top dining table collects fingerprints at the same rate.

These would all fit on a MicroSD card which is smaller than my pinkie fingernail. Technology is amazing. Thumb drive would be overkill...
