Pokemon Go is a free augmented reality mobile game where the picture displayed on the smartphone screen is projected onto real-world locations. The main aim of the game is to catch a Pokemon, a pocket monster.
"The game has sparked concern in Europe, where a potent new privacy regime has recently been established. Nintendo needs to be very careful about how it sets the game’s privacy defaults or it risks legal actions both inside the US and – most acutely – in Europe," Davies said.
The European Union's new General Data Protection Regulation for protecting personal data within the bloc entered into force on May 24, 2016, "to give citizens back control over [the use] of their personal data."
Pokemon Go has become a worldwide hit since its launch two weeks ago and has already been blamed for a wave of crimes, traffic violations and complaints in cities around the globe. Several countries have issued warnings that the game poses a security threat when played by military and intelligence staff.
Indonesia has already banned police and military personnel as well as staff of the presidential palace from playing Pokemon Go while on duty. Earlier this week, the US government issued a warning to military and intelligence personnel to play the mobile game carefully to avoid leaking sensitive geolocation data, while some Arab countries warned residents that the app's geolocation features may be used by criminals to target victims, adding that players of the game were vulnerable to hacker attacks.
