I have noiticed when using trhe web that sometimes a series of boxes
appear with numbers in them.
I am asked to type these numbers into boxes as an authentication.
How does this work??
Thanks

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.

A.k.a. CAPTCHA. http://en.wikipedia.org/wiki/Captcha

There are ways to work around it. The most ingenious proposition is to
set up a free pr0n site that shows the captchas a robot has bumped into
to the clients, and then relays the responses back. The users don't
necessarily know that the optical riddle has nothing to do with getting
access to bare boobies.

1. A robot wants access to a site that uses a captcha to stop robots
2. A user wants to access free XXX
3. The robot forwards the captcha to the client of the XXX site
4. The client replies using human intelligence
5. The client gets access to free XXX
6. The robot forwards the reply to the site that set the captcha
7. The robot gets access to the protected site.
If the XXX site is large enough, it will always have a human client to
consult, whenever the robot needs it.

The numbers are such that a machine would have a very hard time reading
them, but people can. This prevents automated logins.

You read the numbers and type them into boxes.

Hmm, I wonder if something like this would work for spam filters, which
have a hard time reading GIF spam. Could the spam-filter vendors set up
a porn site, and when they need to determine whether a GIF is spam or
someone sending a Dilbert to a friend, they display it as the porn
site's captcha?

It is the ultimate in social engineering: mindless robots outsource
human intelligence from wankers...
