Visiting professors express concerns on how big data, mass surveillance will affect criminal justice system

on

"Hu delivered a presentation on big data and cyberspace in the criminal justice system.

Hu said the government uses mass surveillance to gather data on people. People are “flagged” based on what they do on the internet and when they do it, Hu said.

“In a big data, cyber-surveillance world, the analytical method is to start with the data,” Hu said. “The data becomes suspicions — it’s not necessarily that people are suspicious anymore. This leads to pre-crime ambitions — to stop crime before it starts.”"
