Privacy is being threatened by new technologies that collect and track personal data. Companies are developing facial recognition in phones and cameras, location tracking in vehicles, and smart home meters. The NSA also engages in mass surveillance programs like collecting cell phone metadata and infecting millions of devices with malware. While governments and businesses claim this data is used for security and research, it often leads to abuses of power over individuals. Strong privacy laws and oversight of data collection are needed to curb these threats and restore trust between technology and users.
