摘要： Systems and methods for privacy-preserving cross-domain tracking comprise, for each request received at an authentication server from a device associated with a user: obtaining, at the authentication server, a parent identifier, wherein the parent identifier is a pseudonymous identifier which is unique for the user; obtaining, at the authentication server, a child identifier, wherein the child identifier is associated with a software agent of the user and a domain associated with said each request; and linking, at the authentication server, the parent identifier and the child identifier thereby anonymously tracking the software agent of the user across one or more domains associated with said each request.
