Apple says photos in iCloud will be checked by child abuse detection system

Apple Inc on Monday said that iPhone users’ entire photo libraries will be checked for known child abuse images if they are stored in the online iCloud service.

The disclosure came in a series of media briefings in which Apple is seeking to dispel alarm over its announcement last week that it will scan users’ phones, tablets and computers for millions of illegal pictures.

While Google, Microsoft and other technology platforms check uploaded photos or emailed attachments against a database of identifiers provided by the National Center for Missing and Exploited Children and other clearing houses, security experts faulted Apple’s plan as more invasive.
