Via NPR Science Friday, ‘A new online tracker is snooping on visitors to more than 5,600 popular sites, such as Cancer.org, WhiteHouse.gov and NYDailyNews.com—and its nearly impossible to block. Julia Angwin, author of Dragnet Nation and a senior reporter at ProPublica, talks about “canvas fingerprinting,” as the new technique is called, and what this post-cookie tracker means for privacy online.’ (thanks, Rich)
