Next week marks the inaugural Silicon Valley Human Rights Conference (AKA Rightscon) in San Francisco. This event will explore the role that technology plays in the expansion -- or elimination -- of human rights and the ways that technologists and high-tech firms can either help or harm humanity. In an age when American companies supply "deep packet inspection" technology to the Iranian government so that Iran's secret police can figure out whom to brutally murder (to cite just one example among many), this is an important question.

The Electronic Frontier Foundation is dispatching several staffers to speak at the event, and they've provided a helpful guide to the more interesting sessions to keep an eye on.

Google, a Rightscon sponsor and participating organization, as well as a member of GNI, is just one example of a company that has done a lot of thinking on human rights: its YouTube platform has been instrumental in getting news out of Syria, thanks to a policy that allows violent content to remain available if intended for documentary or educational purposes. And just this week, Google expanded its use of encryption technology to default to SSL search on Google searches.

Twitter, whose General Counsel Alex MacGillivray will be among the keynote speakers at Rightscon, is another company that has taken human rights under consideration when designing its policies, particularly when it comes to free expression. Another rights-thinking company is Mozilla, whom the EFF has praised for its stance on privacy.

On the lists of attendees and sponsors, EFF also sees several companies about which we have grave concerns. A prime example is AT&T, which famously acted in tandem with the NSA to illegally spy on American citizens. Also amongst the participating companies is Comcast, against which the FCC issued an order (crediting EFF research) in 2008 to stop blocking peer-to-peer traffic. Skype is also on our list of companies of concern due to its surveillance capabilities. Skype is also one of several companies in attendance that has been ranked in EFF's Who Has Your Back? campaign (so far, the company has zero stars).

Notably absent from the list are the myriad Silicon Valley companies that provide censorship and surveillance capabilities to authoritarian regimes, among them Boeing's Narus, Cisco (sign our petition here), McAfee/Intel's SmartFilter, and H-P.
