Apple's iPhone 6 leaks continue to surface as the release date approaches. According to the latest video spotted, an iPhone 6 rear casing shows that the the 5.5-inch version of the device will sport a rounded unibody design. More importantly, the rear casing also shows a two-part Apple logo giving more insight as to what the upcoming flagship will look like.

According to Apple Insider, Japanese blog Mac Otakara provided the details of the casing. The video agrees with previous reports about the dimensions and design of the upcoming iPhone 6. The video shows off a microphone hole and rounded flash on the rear-mounted camera. The sides of the device also take a different approach from the iPhone 5s with Apple switching to a more rounded design.

The interior offers a range of screw holes and attachment points. People can also expect a series of plastic features around the top and bottom. What is interesting is that the Apple logo displayed on the back panel's upper part is cut. This may mean that Apple may have other use for the location like an antenna window. The company follows the same thing with the iPad.

Mac Otakara did not discuss the new part. Nonetheless, previous iPhone 6 mock up units leaked from Chinese sources like AliExpress indicate that these may be just speculative parts based on third-party sellers. It may be difficult to nail down the exact specs of the iPhone 6 based on the cases and the dummies. Other reported specs of the iPhone 6 variants include 4.7-inch and 5.5-inch screens, A8 CPU, optical image stabilization and up to 128GB memory.

According to USA Today, Apple's new app and decision to open the Touch ID to third party developers can open up opportunities for biometric banking. However, considering security concerns, bank experts and other organizations wonder how Apple's ecosystem will handle the data and ensure protection.

"Because you can't change it like you can with a credit card number or password," biometric data differ from routinely collected personal information," USA Today quoted Senior Electronic Frontier Foundation lawyer in San Francisco Jennifer Lynch.

"We need to push companies and the government to put policies into place that regulate collection and storage of biometric data." Lynch, who covers privacy and biometrics, added.
