iPhone X Worries Privacy Experts

iPhone Privacy
Apple has already won accolades from privacy experts last September for assuring that facial data used to unlock its new iPhone X would be securely stored on the phone itself.

However, Apple's privacy promises do not extend to the thousands of app developers who will gain access to facial data in order to build entertainment features for iPhone X customers, such as pinning a three-dimensional mask to their face for a selfie or letting a video game character mirror the player's real-world facial expressions.

Apple allows developers to take certain facial data off the phone as long as they agree to seek customer permission and not sell the data to third parties, among other terms in a contract seen by Reuters.

App makers who want to use the new camera on the iPhone X can capture a rough map of a user's face and a stream of more than 50 kinds of facial expressions. This data, which can be removed from the phone and stored on a developer's own servers, can help monitor how often users blink, smile or even raise an eyebrow.

That remote storage raises questions about how effectively Apple can enforce its privacy rules, according to privacy groups such as the American Civil Liberties Union and the Center for Democracy and Technology. Apple maintains that its enforcement tools - which include pre-publication reviews, audits of apps and the threat of kicking developers off its lucrative App Store - are effective.

The data available to developers cannot unlock a phone; that process relies on a mathematical representation of the face rather than a visual map of it, according to documentation about the face unlock system that Apple released to security researchers.

But the relative ease with which developers can whisk away face data to remote servers leaves Apple sending conflicting messages: Face data is highly private when used for authentication, but it is sharable - with the user's permission - when used to build app features.

"The privacy issues around of the use of very sophisticated facial recognition technology for unlocking the phone have been overblown," said Jay Stanley, a senior policy analyst with the American Civil Liberties Union. "The real privacy issues have to do with the access by third-party developers."

The use of face recognition is becoming ubiquitous on everything from social networks to city streets with surveillance cameras. Berlin law enforcement officials in August installed a facial recognition system at the city’s main railway station to test new technology for catching criminals and terrorists.

But privacy concerns loom large. In Illinois, Facebook Inc faces a lawsuit over whether its photo tagging suggestions violated a state law that bars the collection of biometric data without permission. Facebook says it has always been clear with users that it can be turned off and the data for it deleted.

Privacy experts say their concerns about iPhone X are not about government snooping, since huge troves of facial photographs already exist on social media and even in state motor vehicle departments. The issue is more about unscrupulous marketers eager to track users' facial expressions in response to advertisements or content, despite Apple's contractual rules against doing so.

App makers must "obtain clear and conspicuous consent" from users before collecting or storing face data, and can only do so for a legitimate feature of an app, according to the relevant portions of Apple's developer agreement that Apple provided to Reuters.

Apple's iOS operating system also asks users to grant permission for an app to access to any of the phone's cameras.

Apple forbids developers from using the face data for advertising or marketing, and from selling it to data brokers or analytics firms that might use it for those purposes. The company also bans the creation of user profiles that could be used to identify anonymous users, according to its developer agreement.

"The bottom line is, Apple is trying to make this a user experience addition to the iPhone X, and not an advertising addition," said Clare Garvie, an associate with the Center on Privacy & Technology at Georgetown University Law Center in Washington.
