Apple: Face ID is secure as data is encrypted and never leaves the phone37
Once again, Apple's senior vice president of Software Engineering passed along the company line. He stated during a published interview that the data derived by Face ID stays on the phone itself, and nothing is sent to the cloud. Even those adjustments made by Face ID to compensate for changes made to the user's facial appearance (by adding a beard or glasses) are kept exclusively on the iPhone X.
Federighi also responded to Franken's questions about how Face ID was tested by repeating comments previously made by Phil Schiller at last week's unveiling of the tenth anniversary edition of the iPhone. As the software executive stated, "Phil mentioned that we’d gathered a billion images and that we’d done data gathering around the globe to make sure that we had broad geographic and ethnic data sets. Both for testing and validation for great recognition rates."
Apple has responded to questions about Face ID with its own statement, which you will find directly below.
The Apple iPhone X will be available for pre-orders started on October 27th with the official launch taking place on November 3rd. The 64GB model will cost $999 while the version carrying 256GB of native storage will be priced at $1149.
