Final update: Three months after ReadWriteWeb first described these plans in detail, Google announces Google Circles as part of a larger social initiative. It is as we reported it.

We believe that Google will preview a major new social service called Google Circles at South by Southwest Interactive today. Update: Google has now officially denied that Circles will launch here, but not that it exists. See final update below, as of afternoon Texas time Google does now deny that Circles exists. If what we've heard is correct, the service will offer photo, video and status message sharing. Everything users share on Circles will be shared only with the most appropriate circle of social contacts in their lives, not with all your contacts in bulk. Circles may be shown off at an event co-hosted tonight by the ACLU, an organization focused on privacy and the liberties it affords. It may not be a big public launch yet, but it's clear that this is a major product in the works at the very least. Please see below the fold for what I hope will be the final update on this for now.

The service has been developed with extensive participation by Chris Messina, the co-creator of numerous successful social and software phenomena online, from BarCamp to Hashtags and much more. Messina declined to comment for this story. Jonathan Sposato, CEO of the photo editing service Piknik that Google acquired last year, is working on Circles as well. Sposato may be the only entrepreneur to have sold not one but two startups to Google - having founded Phatbits, a service that was acquired by Google in 2005 and became Google Gadgets. These are heavy hitting tech leaders and the service should be very interesting.

United States law enforcement officials have been utilizing data provided by global positioning satellite systems to track down individual suspects, without having to demonstrate probable cause before a judge first - that much is known. Rights groups such as the ACLU have wondered, just how much of that goes on?

The rights group's investigation of this practice has inadvertently triggered a renewal of the debate over privacy policy versus public disclosure, and whether it's possible for an agency or other entity to reveal data that could lead to further revelation of personally identifiable data (PID), without officially violating privacy. The final outcome could set a new precedent for privacy policy, not just by the government but for enterprises as well.

On Monday, 34 American Civil Liberties Union affiliates across the U.S. sent 379 records requests to local law enforcement agencies seeking to know when, how and why they are using cellphone location data to track American citizens. The ACLU wants to know if law enforcement is going over the heads of the U.S. court system to use what should be private information against American citizens. How big of a concern is this for the average American?

The ACLU wants to know how law enforcement obtains and uses location data from cellphones. Are they contacting the cellular operators directly? Are they issuing warrants to the operators? If so, is the person who owns the location data aware of the warrant? The implications are far reaching. Law enforcement's access to location data affects law-abiding private citizens, not just those involved in criminal activities.

Early this morning a coalition of authors, publishers and privacy advocates filed an objection to the Google search settlement case and surprisingly it had little to do with copyright or market control. Notable objectors such as the EFF, ACLU, Samuelson Clinic and authors Cory Doctorow and Jonathan Lethem are worried about privacy. According to a blog post by the EFF, the group is concerned that monitored book search and habit-based tracking could deter readership.
