Apple blocks web-tracking tools used by Facebook

During the inaugural day of company's annual conference for developers in San Jose, California, on Monday, Apple announced iOS 12, the latest version of its mobile operating system and also previewed macOS "Mojave", the latest version of its desktop operating system.

Besides making daily tasks faster and giving parents new tools to have more control of the time children spend interacting with iPhones and iPads, iOS 12 will also have new privacy features.

"As with all Apple software updates, enhanced privacy and security remain a top priority in iOS 12," Apple said in a statement.

In the web browser Safari, enhanced "Intelligent Tracking Prevention" helps block social media "Like" or "Share" buttons and comment widgets from tracking users without permission, the Cupertino, California-headquartered tech giant said.

"Safari now also presents simplified system information when users browse the web, preventing them from being tracked based on their system configuration," Apple added.

Industry experts believe that the move is likely to add to tensions between Apple and Facebook.

Apple's chief executive Tim Cook had previously described Facebook's practices as being an "invasion of privacy" -- an opinion Facebook's founder Mark Zuckerberg subsequently denounced as being "glib", the BBC reported on Monday.

At the Apple Worldwide Developers Conference (WWDC) 2018, the company's software chief Craig Federighi said that Facebook keeps watch over people in ways they might not be aware of.

"We've all seen these - these like buttons, and share buttons and these comment fields.

"Well it turns out these can be used to track you, whether you click on them or not," Federighi was quoted as saying.

Apple's privacy initiative has already been lauded by industry experts.

"Apple is making changes to the core of how the browser works -- surprisingly strong changes that should enable greater privacy," Kevin Beaumont, a cyber-security expert, was quoted as saying by the BBC.

Apple also said that MacOS Mojave would combat a technique called "fingerprinting", in which advertisers try to track users who delete their cookies.

The method involves identifying computers by the fonts and plug-ins installed among other configuration details.

To counter this, Apple will present web pages with less details about the computer, the BBC report said..

"As a result your Mac will look more like everyone else's Mac, and it will be dramatically more difficult for data companies to uniquely identify your device," Federighi explained.
