FILE - In this Dec. 8, 2011 file photo, Harriman, Tenn., resident Shannon Robinson shows the map displayed on his GPS device that tracks the location of his hunting dogs. Animal rights groups are suing California over rules that allow animals to be hunted with the aid of hunting dogs wearing GPS tracking devices on their collars. The Animal Legal Defense Fund says the hunting method is "cruel and unfair." The group says tracking devices allow dogs to chase prey to the point of exhaustion. Then hunters follow the GPS to find an animal that is easily shot. The lawsuit targets the Fish and Game Commission, which didn't immediately respond to requests for comment.

FILE - In this Aug. 31, 2018, file photo, a child and a woman wait outside a school entrance mounted with surveillance cameras and barricades with multiple layers of barbed wire in Peyzawat, western China's Xinjiang region. The Chinese database Victor Gevers found online was not just a collection of old personal details. The discovery by Gevers, a Dutch cybersecurity researcher who revealed it on Twitter last week, has given a rare glimpse into China’s extensive surveillance of Xinjiang, a remote region home to an ethnic minority population that is largely Muslim. The area has been blanketed with police checkpoints and security cameras that apparently are doing more than just recording what happens. The database Gevers found appears to have been recording people’s movements tracked by facial recognition technology, he said, logging more than 6.7 million coordinates in a span of 24 hours.

FILE - In this July 20, 2016 file photo, six fitness tracking devices measuring step counts and other fitness features are worn in New York. A new Pentagon order says military troops and other defense personnel on certain sensitive bases and warzone areas won’t be allowed to use fitness tracker or cellphone applications that can reveal their location. The memo stops short of banning the fitness trackers or other electronic devices, which are often linked to cell phone applications and can provide the users’ GPS details to social media. It says GPS technologies present significant risk to personnel. (AP Photo/Bebeto Matthews)

In this Oct. 30, 2017, photo provided by the Connecticut Department of Energy and Environmental Protection, Wildlife Biologist Jason Hawley affixes a GPS tracking collar on a bobcat at the Sessions Woods Wildlife Management in Burlington, Conn. GPS collars were placed on several dozen bobcats in the fall of 2017 to track their movements. The collars are programmed to fall off on and after Aug. 1, 2018. The agency wants to find all the collars, recharge the batteries and place them on other bobcats in the fall to continue the study.
