I am asked to type these numbers into boxes as an authentication.

How does this work??

That interaction "proves" that a human is reading the page rather than
a computer program such as a spider indexing the contents, because the
number you see is sent as a picture which the program can not interpret,
or could only interpret with high effort and significant error.

I might use this method to keep an advertiser-supported service from
being pirated by another site that would access my service from a
program and surround my results into their advertising.
