Apple is in the news again over patent infringement dispute for an application feature, which resembles the feature of a mail service called Blue Mail created by the user Blix.
Blue Mail application provides the ability to create and use masked email addresses to send and receive emails without ever giving up your real email address. The Apple new Sign-In service works in a similar way as a user can create new random email addresses and send emails back and forth with the help of Apple account credentials.
