Apple SVP of Software Engineering Craig Federighi demonstrated how a user could apply Bing's Translate extension to Safari to translate the text on a Japanese website into English, as well as share an item from the page via a Pinterest extension. Federighi added that user data would not be shared between the apps.
Federighi also said that third-party app providers will be able to "take advantage" of the TouchID fingerprint sensor on the iPhone but did not specify how.
About 83% of iPhone owners whose phones include the TouchID feature use it to authenticate their devices, according to Federighi, who added that the actual fingerprint data will not be shared with third-party vendors. An anonymized version of the fingerprint data could serve as another data point to further connect users across mobile devices and channels, especially if it is implemented in Apple's other devices.
There are also rumors that Apple will unfurl enhancements to its iBeacon technology during the WWDC, giving advertisers more ways to connect with consumers.
