Google may be helping the government conduct warrantless searches into your online behavior, according to the Electronic Privacy Information Center.

According to an amicus brief filed by the Electronic Privacy Information Center (EPIC), Google is scanning billions of user files in search for illegal content. The brief, which was was highlighted in a report by Tom’s Hardware this week, alleges that Google searches user files and then sends information to various law enforcement agencies.

The brief claims that Google has developed a proprietary algorithm to investigate files uploaded by their users. The algorithm, which has not been made available for public inspection, then automatically sends information on offending users to law enforcement agencies.
