What would your internet searches reveal about you if others could scrutinize and second-guess them? It’s something to think about, given that the big search engines, like Google, store search histories and make them available to the authorities. In fact, as happened in a recently decided Colorado case, police can start from search terms of interest and pressure tech companies to surrender the identities of anyone who has surfed for specified keywords. The decision is chilling for anybody who has ever pondered their online history in the hands of a stranger—or who just cares about privacy.
“Today, the Colorado Supreme Court became the first state supreme court in the country to address the constitutionality of a keyword warrant—a digital dragnet tool that allows law enforcement to identify everyone who searched the internet for a specific term or phrase,” Jennifer Lynch and Andrew Crocker of the Electronic Frontier Foundation (EFF) reported on Monday. “The case is People v. Seymour, which involved a tragic home arson that killed several people. Police didn’t have a suspect, so they used a keyword warrant to ask Google for identifying information on anyone and everyone who searched for variations on the home’s street address in the two weeks prior to the arson.”
