## Abstract

A first terminal configured to operate in conjunction with a second terminal, the first terminal including: a sensor configured to obtain information corresponding to a motion of the first terminal; a communicator configured to receive information corresponding to a motion of the second terminal from the second terminal; and a controller configured to, in response to a distance between the first terminal and the second terminal being greater than or equal to a critical value, control the communicator to transmit a notification message to the second terminal based on the information corresponding to the motion of the first terminal and the information corresponding to the motion of the second terminal.

## Claims

### Claim 1

A first electronic device for operating in an information protection mode, the first electronic device comprising:
a communicator configured to communicate with a second electronic device; and
a controller configured to, based on a signal strength of a signal transmitted to the second electronic device by the communicator or a signal strength of a signal from the second electronic device received by the communicator, control the first electronic device to operate in the information protection mode.

### Claim 2 (depends on 1)

The first electronic device according to claim 1, wherein the controller is further configured to, when the first electronic device operates in the information protection mode, control operations of the first electronic device based on state information of the first electronic device and state information of the second electronic device.

### Claim 3 (depends on 1)

The first electronic device according to claim 1, wherein the controller is further configured to, when the first electronic device operates in the information protection mode and in response to an attempt to unlock the first electronic device, control the communicator to transmit a notification of the attempt to unlock the first electronic device.

### Claim 4 (depends on 1)

The first electronic device according to claim 1, wherein
the second electronic device comprises a wearable device, and
the controller is further configured to, in response to a determination that the wearable device is not being worn by a user, end a communication between the communicator and the wearable device.

### Claim 5 (depends on 2)

The first electronic device according to claim 2, wherein
the state information of the first electronic device corresponds to movement of the first electronic device, and
the state information of the second electronic device corresponds to movement of the second electronic device.

### Claim 6

A non-transitory computer-readable medium having stored thereon instructions executable by a first electronic device to cause the first electronic device to perform:
controlling to communicate with a second electronic device by a communicator; and
controlling to operate in an information protection mode based on a signal strength of a signal transmitted to the second electronic device by the communicator or a signal strength of a signal from the second electronic device received by the communicator.
