A method, apparatus, and system for using Bluetooth devices to secure sensitive data on other Bluetooth devices is described. A Bluetooth device is paired with a “trusted” Bluetooth device. When contact with the trusted device is lost, designated sensitive data on the secured Bluetooth device is automatically encrypted. When contact is restored, the data is automatically decrypted. In an alternate embodiment, a secured device can be associated with multiple trusted devices, and the secured device designate different sensitive data for each trusted device. In this way, multiple users can share a common, “public” Bluetooth device without concern that the other users will access their sensitive data on the device when the device is not being used by that user.
