With more than 38-million people and some of the largest technology companies in the world calling California home, the Golden State should be a leader in safeguarding electronic privacy. For years the state’s constitution has provided greater privacy protection than the Fourth Amendment. But when it comes to electronic privacy, the state has lagged behind, even as other states, such as Texas and Maine, have passed legislation to protect everything from the contents of email to the detailed location information generated by our phones.
Not anymore.
Update 2014-01-16: Turn announced today they will suspend their zombie cookie program by early February, but left open the possibility to resume in the future. We ask that they end the program permanently.
Verizon advertising partner Turn has been caught using Verizon Wireless's UIDH tracking header to resurrect deleted tracking cookies and share them with dozens of major websites and ad networks, forming a vast web of non-consensual online tracking. Explosive research from Stanford security expert Jonathan Mayer shows that, as we warned in November, Verizon's UIDH header is being used as an undeletable perma-cookie that makes it impossible for customers to meaningfully control their online privacy.
Mayer's research, described in ProPublica, shows that advertising network and Verizon partner Turn is using the UIDH header value to re-identify and re-cookie users who have taken careful steps to clear their cookies for privacy purposes. This contradicts standard browser privacy controls, users' expectations, and Verizon's own claims that the UIDH header won't be used to track users because it changes periodically.
2014 has seen a flurry of events surrounding the issues of privacy and security when it comes to mobile devices. Here are some highlights.
EFF started the year by releasing HTTPS Everywhere on Firefox for Android. Before, HTTPS Everywhere could only protect web browsing on desktop platforms, but with the release of HTTPS Everywhere for Firefox for Android, that same protection became available for Android devices as well.
