Abstract
A method of protecting data stored by an electronic device includes determining an identity of a restricted device. Also determined is the identity of restricted data associated with the restricted device, the restricted data being one or more items of data stored by the electronic device. Data protection for the restricted data to limit access to the restricted data by the restricted device in invoked when geographic presence of the restricted device with respect to the electronic device is detected.
Claims18
A method of protecting data stored by an electronic device, comprising:
- receiving an identifier of a restricted device;
- determining an identity of the restricted device based on said identifier;
- determining restricted data associated with the restricted device, the restricted data being one or more items of data stored by the electronic device;
- identifying a data directory not accessible by said restricted device;
- detecting geographic presence of the restricted device with respect to the electronic device;
- and
- determining cloaking settings for the restricted data to limit access to the restricted data by the restricted device, wherein the data protection for the restricted data includes disabling an ability to access the restricted data using the restricted device by cloaking the data directory to hide the existence of the restricted data as part of the data stored by the electronic device.
4 more elements
An electronic device, comprising:
- a memory that stores data, some of the data being specified by a user of the electronic device as restricted data for an associated restricted device;
- and
- a control circuit that is configured to protect the restricted data by limiting access to the restricted data by the restricted device when the restricted device is detected to be in a geographic presence with respect to the electronic device, wherein the data protection for the restricted data includes determining cloaking settings for the restricted data to limit access to the restricted data by the restricted device by disabling an ability to access the restricted data using the restricted device by cloaking a data directory to hide the existence of the restricted data as part of the data stored by the electronic device.
