Sorry about the repeat posts - they've now been replaced with a dot (couldn't delete them for some reason). When I tried to initially submit, I kept getting an error page so I kept doing it over and over again.

I really wish i could tell you how we do this but it is all software that is written in house. Plus manually reviewing all order placed and having a feeling about a order and patteren recognition. Am a fraud reviewer for the largest e-commerence company in the world and we really do not want this type of information to get out. I do Fraud protection for over 35,000 different companies online.
Normally we are dealing with Fraud rings that attack us. But we also have to protect us from the customers that charge items and do a chargeback without going thru the proper channels, or trying to return something after the date.
If you want to send me a PM with some questions i will see what i can answer.

1. Identity tracing with CCs
2. IP addresses
3. cookies
3. MAC addresses of network adapters and cable modems?? (not sure of this, is this possible to obtain this info?)
4. hostname aka computer name (can this be done?)
5. browser (and version), os (and version), processor (even if these were obtained, many many people have the same configuration so I doubt this is an effective method to block the specific person who you want to block but probably useful for tailoring the appearance of the page)
What other possible methods can modern websites use to know who is coming to their site?

I guess as somewhat of an engineer, feel weird not knowing something. Does this mean that the site knows who I am if it knows what I input before? Does the fact that when I log into a secure area (like the pop up boxes I've linked in my initial post) and that the fields pre-fill with values I input before mean that the site knows who I am? Or is this something that is on my side (client) exclusively? If the former, how do they do this even though I cleaned out all conventional data (I cleared out cookies, temp internet files, autocomplete, in my tools --> internet options in IE and deleted all files within my documents of my xp login system folder)? Is there something I'm overlooking? Btw, I never installed anything from websites either. Thanks for your help.
