Last week, Apple made an announcement about some new security features it would be offering to users. One of those features involves users' ability to opt in to encryption for iPhone backups to iCloud. While this new feature will enhance data privacy and security for those users who choose to opt in, it may create additional challenges for law enforcement to obtain evidence in criminal investigations.To discuss the implications and potential impact of this new security feature, Lawfare senior editor Stephanie Pell sat down with Riana Pfefferkorn, research scholar at the Stanford Internet Observatory. They discussed the costs and benefits to users who may choose to opt in to this feature, how Apple's choice to offer this feature plays into a broader conflict known as the Crypto Wars, and how this feature relates to another part of Apple's announcement where it indicated that it would not be scanning all iPhones for child sexual abuse material before images were backed up to iCloud.Support this show http://supporter.acast.com/lawfare.
