Installing GPS trackers without permission to obtain a person's whereabouts is an illegal act that infringes on citizens' personal information.
Citizens' whereabouts information is strictly protected by law. Illegally obtaining, selling, or using such information may constitute a crime and easily breed downstream offenses.
Some GPS trackers have been modified to include microphones and other functions, turning them into eavesdropping devices and falling into a legal regulatory blind spot. Their production, sale, and use are suspected of being illegal.
Related cases exhibit characteristics of being chain-like and covert. Industries such as vehicle rental and financial lending are prohibited from using illegally installed tracking devices for risk control or debt collection.
