Microsoft Patents Multi-Domain User Tracking With Cookies
from the this-is-new? dept
theodp writes "A patent for Tracking usage behavior in computer systems was granted to Microsoft Tuesday after the software giant explained how it can use invisible images and 'small sized cookies' to surreptitiously track visitors on its own and others' web sites." The claims seem to get fairly specific, concerning keeping the cookies small (as to be less resource intensive) and using the system across multiple domains (generally frowned upon for cookie usage) to track usage outside the single domain.
