Simple database. Social, name, date of last appearance, money won. You could do it in a couple of megs.
A bit *too* simple; there are legitimate reasons for getting a new SSN, and some names are very common.

Throw DOB on top of that and a match will raise enough of a flag to warrant further investigation whilst adding precisely sixteen bits per record.

I'd say Name, DOB and SSN would suffice. It apparently works for blood donation centers. My sister recently gave blood at her high school blood drive and two days later when they entered her info and started processing her blood, the computer red flagged her and her blood because she had the same first name and DOB AND blood type to someone who lived in a town 5 miles away (Weird coincidence? I know.). They called to verify that she wasn't donating under a different last name, but if they can red flag a person that easily, Jeopardy should be able to do the same.
