NEW YORK (AP) — Apple plans to tighten its online security measures to reduce the chances of its users being victimized by intrusions like the ones that stole nude photos from actress Jennifer Lawrence and other celebrities.

CEO Tim Cook told The Wall Street Journal in a story published Friday that Apple Inc. will use email and push notifications to alert the hundreds of millions of people using its services when there has been an attempt to restore their iCloud data on a new device, change an account password or log on to an account with a new device. Previously there were no notifications for restoring iCloud data, but users did receive an email when someone tried to change a password or log in for the first time from a new device.
