What is the purpose of the US Department of Homeland Security to collect immigrant social media information?

According to foreign media reports, the US Department of Homeland Security began to collect "social media accounts, aliases, relevant identity information and search results" of all immigrants who want to enter US territory on June 5438+08.

According to reports, the initiative was announced at the end of September, but the US Department of Homeland Security has been tight-lipped about how to collect data and how to conduct inspections. Foreign media said that this wide-ranging initiative further expanded the previous efforts of former President Barack Obama.

Talbert, a spokesman for the US Department of Homeland Security, said, "This is not a new policy. The Department of Homeland Security has been paying attention to the content of social media in the process of law enforcement and immigration review to protect national security. "
