Happy to help spread the word :)

Good question, and a bit technical for me, but I did find this in the comments section of that article:

<Sean, the patent application describing the technology is here:
www.google.com/patents

Looks like it gathers your hardware/software configuration (called a "fingerprint"), stores that in their central database server and in a flash cookie on your machine, and associates it with a screen name (like a poker login). If you reformat your hard drive, the central server just re-stores the cookie the next time you log in to the poker site with that screen name. The method also allows for some minor changes in your system configuration, like swapping out a network card, and simply associates your screen name with your latest information the next time you log in.

Unless they've figured out otherwise, the only way to create a new fingerprint and perhaps become anonymous again would be to drastically swap out your software and hardware and reformat your drive, or maybe at least swap out some undetermined critical component(s) (the patent suggests that getting a new CPU serial number would be a critical change). I'm sure the ACTUAL method you would use to avoid simply being re-associated with your new system configuration is tightly held at iovation. Even then, your fresh system would be flagged because its fingerprint doesn't match what was previously associated with your login.

The non-anonymity privacy concerns aside, I think an even bigger issue is that iovation's goal is to share your digital fingerprint among all its clients. That way if one website flags your account for fraud (rightly or wrongly), iovation alerts other client sites with whom you have accounts. Even assuming nothing insidious comes of that (not a fair assumption), the potential for unregulated abuse is huge. Think of iovation like a credit agency that collects your digital credit score information. We already know what happens if bad information gets in there (like when your credit card or identity is stolen) and how difficult it is to fix it. See www.iovation.com/images/pdf/dra_wp.pdf >

In case the links don't work:

The iovation link gets me to a 404 error

Does this help?
