这个事很无奈,应引起重视!属于个人信息安全问题,恶意挖掘个人信息要遏制!!! DoNotTrack.Us is a collaboration of researchers at the
Stanford Law SchoolCenter for Internet and Society
and the
Security Laboratory
at the Stanford Department of Computer Science to explore implementation and foster pluralist discussion of Do Not Track. The principal researchers are
Jonathan Mayer and
Arvind Narayanan. Overview
Do Not Track is a technology that enables users to opt out of
third-party web tracking, including behavioral advertising. At present a
user cannot opt out of many of the hundreds of tracking services and
advertising networks; those that do allow opting out each require
setting (and not deleting!) an opt-out cookie. Much like the popular Do
Not Call registry, Do Not Track provides users with a single,
persistent setting to opt out of web tracking.
Here's how it works: Whenever a web browser requests content or
sends data using HTTP, the protocol that underlies the web, it can
optionally include extra information, called a "header." Do Not Track
simply adds a header indicating the user wishes to not be tracked. Note
that Do Not Track differs from the Do Not Call registry in employing a
decentralized design; it thus avoids the substantial technical and
privacy challenges inherent to compiling, updating, and sharing a
comprehensive registry of tracking services or web users.
Compliance with Do Not Track could be purely voluntary, enforced by
industry self-regulation, or mandated by state or federal law. We do
not take a position on these alternatives.
