“In order to use Ticket Tag, you simply place your finger on a reader. The system, which utilizes the technology of biometrics, takes an image of your finger, converts the image into a unique numerical value and immediately discards the image. The numerical value is recalled when you use Ticket Tag with the same ticket to re-enter or visit another Park. Ticket Tag does not store fingerprints.”
(Personal experience)
That's SO reassuring.
So nothing prevents them from taking the packages of their fries stand, get fingerprint images from them, figure out who it is, and send you an offer for 50% off the weight loss holiday package ?
What exactly does privacy for fingerprints imply, except that people are not able to do exactly that ? And I don't mean that they won't. Privacy means they CAN'T. Not even if the next Disney CEO is Vladimir Putin.
This is what gets me about most arguments around privacy maximal-ism the end result especially for a company like Disney is ridiculously circuitous and could be easily achieved with much lower costs. Why in the world would they go through all that trouble when everyone is either on camera or paying with credit card/the Disney wristband.
Sure, it may be hypothetically possible. But is it realistically going to happen? Of course not.
BigInt picToNumber(pic){
BigInt x = 0;
for (int r=0;r<pic.w;r++)
for (int c=0;c<pic.h;c++)
x = (x*265)+pic.pixel(r,c);
return x;
}
Perfect for storing a quantity of high resolution “unique numbers” which you might need to recall at some point, when you want to match them up with other oddly similar (but not precisely equal) high resolution unique numbers.
I hear that you can convert images to “unique numbers” using a technique known as “lossless compression” but that stuff’s all way above my pay grade.
