Microsoft’s cofounder apparently shares those concerns. A recently surfaced patent naming Gates specifically as co-inventor details technology for computers and mobile devices that alert users to any cameras within their vicinity and blurs or edits the content displayed on their device in order to protect it from being recorded and surveilled.
