Meet the Online Tracking Device That is Virtually Impossible to Block

This is an interesting new tracking method that I`ve seen in a few places.

The basic idea is to gather machine and browser data of a request and turn it into a signature that uniquely identifies that browser. That way you can track people without needing cookies.

These trackers aim to report on individual users activities.

It has to be limited. One small change like a browser upgrade would probably change a signature and break the tracking. It is also browser specific and not user specific so no cross device tracking is possible.? Meet the Online Tracking Device That is Virtually Impossible to Block
