South Korea's Personal Information Protection Commission said on May 19 it published a personal data protection guide for users of generative AI services to address common questions. It said the guide focuses on strengthening users' AI literacy, based on complaints, policy proposals and consultation cases. The guide visualises how personal data is processed from collection to AI training and service use, and covers user-controlled functions such as opting out of training and managing chat record storage and deletion.

Western Digital said on May 19 it integrated post-quantum cryptography into its latest high-capacity Ultrastar UltraSMR hard disk drives. The company said it will introduce HDDs that apply quantum-resistant algorithms approved by the U.S. National Institute of Standards and Technology. Western Digital said the move shows quantum security is shifting from theory to hardware-level defense and could help protect large-scale data lakes backing AI innovation from future quantum computers.
