Apple has patented facial technology, which will be added as another security measure for its devices.

The company already added the fingerprint sensor to the latest iPhone 5S, and they are expected to take security steps further by adding on the facial technology, which detects and recognizes actual faces.

Apple's next flagship phone, the iPhone 6, is expected to pack a sapphire glass screen, which will be very hardwearing and stronger than concrete. The glass will be scratch-resistant and will not break easily.

According to The Mirror, the company has spent $578 million to develop the iPhone 6. This is because the sapphire glass is more difficult to produce than the Corning Gorilla Glass that is currently used for the iPhone 5S. The funds are reportedly being used towards the development of furnaces that will produce the sapphire glass in large quantities.

Last month, reported that Apple bought PrimeSense, an Israeli chipmaker company responsible for producing gesture-detecting sensors similar to the Kinect controller for Microsoft's Xbox 360.

According to Reuters, the company was bought for $345 million.

The acquisition of PrimeSense may mean that Apple may incorporate the 3D machine vision gesture controls to all of its devices, including the Apple TV, iPad tablets and future iPhones. The technology allows digital devices to observe a scene in 3D.

Apple and PrimeSense have not officially announced anything as of yet and only time will tell how Apple will be using the 3D motion sensor in its devices.

The iPhone 6 is expected to release some time in 2014 and is speculated to pack a bigger 4.7 to 5.5 inch display with sapphire glass, Liquidmetal body, 4GB RAM, 64-bit A8 processor, dedicated M7 chip and 128 GB Storage.
