Is there any way to link this data over longer periods of time?
A lot of data can change over days, weeks, but if you can maintain an accurate fingerprint with tinier changes, and granted you have consistent visits from the user, could you just keep up?
Especially if one service is tapped into several websites, and can continually keep up with smaller data changes and distribute that info. Is this possible? In practice anywhere?
I'm thinking that you just need one website where you can associate a given fingerprint to a specific user and then tracking its activity around the web becomes easy.
Let's say I'm logged in a famous search engine, they associate my fingerprint X to my account A. If they then encounter fingerprint X anywhere else, there is a good chance it was me, A, doing it. If the next day I get fingerprint Y, it gets attached to A as well and the tracking information follows it.
Does this make sense?
You mean, like a really popular web service or app that someone would log into every day/week/month...?
Even easier if, additionally, many of the smaller websites were syndicated into a tracking network?
