LONDON (AP) — Travelers should prepare for extra scrutiny of devices when crossing borders, especially when entering the U.S. Experts say 100% privacy might be impossible but there things you can do to make it harder for someone to see your private data. If possible, leave your phone at home. If you need one, you could get a temporary device with just the information needed for your trip. If you have to bring your phone or laptop, store any sensitive information in a cloud storage service and then delete it from the device. Power off your phone when you get to the border. Turn off biometrics and used PINs and passcodes instead.
