The U.S. Supreme Court decision to overturn Roe v. Wade resulted in data brokers becoming key cogs in some states’ efforts to criminalize reproductive health care, Duke University graduate Joanne Kim and undergrad student Aden Klein write in the Technology Policy Press. They said that beyond personal data obtained from period tracker health applications, data brokers “have already been outed for selling data on pregnant women and abortion-relation information.” Both writers previously worked on Duke’s data brokerage research project. They said states that criminalized abortion procedures “could abuse this unregulated data economy for abortion surveillance purposes.”
