When you’re messing with reality, you’re probably going to want a decent security system.

Augmented reality company Magic Leap has acquired the Israeli-based NorthBit to help increase its security, via Geek Time. Augmented and virtual reality could become a $120 billion market by 2020, according to tech adviser Digi-Capital. AR could have multiple uses, from gaming to more practical applications like assisting a doctor in surgery by displaying holographic information about a patient’s organs. Making sure security is tight is important for any company investing in the emerging field. Increased security can prevent outsiders from accessing a company’s network and protect its users’ personal information.

NorthBit was able to hack the Android operating system last month, which likely alerted them to Magic Leap, a company with a valuation of $4.5 billion and impressive investors like Google, JP Morgan, Warner Bros., and the Alibaba Group from China.

Magic Leap is specifically working on cinematic experiences with AR, which you can see a demo of below.

Magic Leap, which opened back in 2011, differs from AR competitor Microsoft, which is working on HoloLens. The HoleLens uses stereoscopic tech, while Magic Leap uses “digital lightfields” to project images straight to a user’s eyes.
