New submitter wermske writes "Ars Technica and ZDNet report the Location Privacy Act of 2012 (SB-1434) was passed by the California legislature on Wednesday. The California Location Privacy Act, co-sponsored by the ACLU of California and the Electronic Frontier Foundation, updates California privacy law to reflect the modern mobile world by providing needed protection against warrantless government access to a person's location information. Recent reports indicate that cell phone tracking is routine and few agencies obtain warrants for such surveillance. The need for this protection resurfaced last week when warrantless GPS tracking appeared again in the national news — a federal appeals court ruled that law enforcement is allowed to track the GPS signal coming from a suspect's prepaid phone without a warrant. The scope of the Location Privacy Act would include gathering GPS or other location-tracking data from cell phones, tablets, computers, automobiles, etc. The next stop is the governor's desk; however, there is concern that Governor Jerry Brown may not sign this act into law. In 2011, Gov. Brown vetoed an attempt at enforcing stricter privacy rules."
