## Abstract

According to one embodiment, an electronic apparatus comprises a communication module and a connection control module. The communication module is configured to execute close proximity wireless transfer. The connection control module is configured to start an operation of establishing a connection between the communication module and an external device which is in close proximity to the communication module if an identifier of the external device wirelessly transmitted from the external device is included in a connection permission list. The connection control module is configured to display a password entry screen if the identifier is not included in the connection permission list, and to add, if a password entered on the password entry screen matches with a registered password, the identifier to the connection permission list and start the operation of establishing the connection between the communication module and the external device.

## Claims

### Claim 1

An electronic apparatus comprising:
a communication device configured to execute close proximity wireless transfer; and
a controller configured to restrict devices which are connectable to the communication device by using a connection permission list indicative of identifiers of one or more devices which are permitted to establish a connection for close proximity wireless transfer with the communication device,
wherein the controller is configured to determine whether an identifier of an external device in close proximity to the communication device is on the connection permission list, the identifier being wirelesslv transmitted from the external device to the communication device,
wherein the controller is configured to start an operation of establishing a connection between the communication device and the external device if the identifier of the external device is on the connection permission list, and
wherein the controller is configured to display a password entry screen prompting a user of the electronic apparatus to confirm whether the external device is to be registered as a device which is permitted to establish a connection for close proximity wireless transfer with the communication device if the identifier is not on the connection permission list, and if a password entered on the password entry screen matches with a registered password, the controller is configured to add the identifier to the connection permission list to register the external device as the device which is permitted to establish a connection for close proximity wireless transfer with the communication device, and start the operation of establishing the connection between the communication device and the external device.

### Claim 2 (depends on 1)

The electronic apparatus of claim 1, wherein the controller is further configured to set an operation mode of controlling the close proximity wireless transfer to either a first mode or a second mode,
wherein the controller is configured to display the password entry screen if the identifier is not on the connection permission list in the first mode, and
wherein the controller is configured to add the identifier to the connection permission list if the identifier is not on the connection permission list in the second mode.

### Claim 3 (depends on 2)

The electronic apparatus of claim 2, wherein the controller is configured to display a confirmation screen which allows a user to confirm whether the device identified by the identifier is to be added to the connection permission list, if the identifier is not on the connection permission list in the second mode, and to add the identifier to the connection permission list if the user confirms that the device is to be added.

### Claim 4 (depends on 1)

The electronic apparatus of claim 1, wherein the controller is further configured:
to display a password registration screen in response to a password registration request, and to store a password entered on the password registration screen as the registered password; and
to display a password registration screen if the password registration request is received in a state where the registered password is stored, to store a password entered on the password registration screen as a new registered password, and to delete identifiers on the connection permission list.

### Claim 5 (depends on 1)

The electronic apparatus of claim 1, wherein the controller is further configured to restrict the registered password to comprise only numerals.

### Claim 6

A communication control method of controlling close proximity wireless transfer of a communication device in an electronic apparatus, comprising:
determining whether an identifier of an external device in close proximity to the communication device is on a connection permission list the connection permission list being indicative of identifiers of one or more devices which are permitted to establish a connection for close proximity wireless transfer with the communication device, the identifier being wirelessly transmitted from the external device to the communication device;
starting an operation of establishing a connection between the communication device and the external device if the identifier is on the connection permission list;
displaying a password entry screen prompting a user of the electronic apparatus to confirm whether the external device is to be registered as a device which is permitted to establish a connection for close proximity wireless transfer with the communication device if the identifier is not on the connection permission module; and
adding, if a password entered on the password entry screen matches with a registered password, the identifier to the connection permission list to register the external device as the device which is permitted to establish a connection for close proximity wireless transfer with the communication device, and starting the operation of establishing the connection between the communication device and the external device.

### Claim 7 (depends on 6)

The communication control method of claim 6, further comprising setting an operation mode of controlling the close proximity wireless transfer to either a first mode or a second mode,
wherein the password entry screen is displayed if the identifier is not on the connection permission list in the first mode, and
wherein the identifier is added to the connection permission list if the identifier is not included in the connection permission list in the second mode.

### Claim 8 (depends on 6)

The communication control method of claim 6, further comprising:
displaying a password registration screen in response to a password registration request, and storing a password entered on the password registration screen as the registered password; and
displaying a password registration screen when the password registration request is received in a state where the registered password is stored, changing the stored registered password to a password entered on the password registration screen, and deleting identifiers on the connection permission list.
