"The service checks to see if the hashed value exists and then lets you know if your udid is among the ones compromised. Only hashed values are stored in the service, not any of the raw udid values."

So all the site owner has to do is hash the udids to know who you are?

The udids have already all been hashed. It is the hashed values only that are stored on the site. The only piece of information sent to the site is a hashed udid (the udid is hashed on the browser before any information is sent over the wire).

I realize that. But all the site owner has to do is keep a list of the UDID->hash mapping and then he can lookup the original UDID...

If your UDID tests negative, you still could be compromised. The original FBI file had 12 million. AntiSec released 1 million.

This linked testing site says 20 million, which is wrong, as far as I know.

Thanks for info. I've updated the information on the page.
