A tool trialed at the 2011 Rugby World Cup is now being used by police to scan social media for real-time information in order to prevent crimes and increase public safety, reports stuff.co.nz. Authorities say the software, Signal, scans only publicly-available postings and they are using it to search for keywords and hashtags in order to monitor large group activity. Signal will identify where messages are being sent from if Internet users have geolocation activated on their device. A privacy commission spokeswoman verified that the software appears to access only public information.
