Description

The present application claims priority from Japanese Patent Application No. JP 2010-134178 filed in the Japanese Patent Office on Jun. 11, 2010, the entire content of which is incorporated herein by reference.

BACKGROUND

This disclosure relates to an information processing device capable of communicating with devices on a network, and an information processing program which are suitable for such an information processing device.

Recently, with the penetration of digital consumer electronics capable of accessing LAN (local area network), digital contents such as videos, photographs, and music become easily shared through LAN. One of the technical specifications for using devices such as personal computers, consumer electronics, mobile terminals, digital cameras, and mobile phones which are mutually connected and worked together through LAN is DLNA (digital living network alliance) guidelines.

In the DLNA guidelines, with use of UPnP (universal plug and play), it is possible to search a device connected to LAN, or to capture a content list. Further, in the guidelines, contents stored in a certain device on LAN may be reproduced by other devices.

Wireless LAN is also gradually penetrated with the penetration of LAN. Those not familiar with setting of an encrypted communication of wireless LAN is also inevitably increased with penetration of wireless LAN. As a result, for example, while a user is unaware that outside leakage of the electric waves from user's house occurs and others' devices are connectable to the user's wireless LAN, contents owned by the user are at risk of being looked furtively by others. Thus, Wi-Fi Alliance that is an industry group of wireless LAN vender formulates Wi-Fi Protected Setup (WPS) as an implementation specification for setting an encrypted communication of wireless LAN easily. Note that the logo of Wi-Fi is a registered trademark of Wi-Fi Alliance.

Before formulation of WPS, unique specifications for simplifying setting procedures of an encryption key have been implemented in products by many manufacturers, and recently, some methods in which the user does not need to input a password that is for generating an encryption key necessary for an encrypted communication and is called PIN (personal identification number) have been widely used. For example, as described on Buffalo's website: http://buffalo.jp/aoss/, a method in which an AOSS (AirStation One-Touch Secure System) (registered trademark of Buffalo Inc.) button of a device to be connected to a wireless LAN is pressed within a predetermined time period after an AOSS button of an access point is pressed, thereby performing authentication has been in practical use as a simple setting method. Moreover, as described on a website of AtermStation: http://121ware.com/product/atermstation/special/rakuraku_start/index.html, a method in which a predetermined button of an access point is pressed to perform authentication has been in practical use as a simple setting method.

However, in the above-described methods, since it is necessary to press a button of an access point, it is extremely inconvenience when a device located away from the access point accesses to a wireless LAN, or when the access point is disposed at a place beyond the reach of a person, for example, under the roof. As described above, the methods in the related art have difficulty that usability of a user is impaired for authentication.

SUMMARY

It is desirable to provide an information processing device and an information processing program which are capable of performing wireless network connection safely without impairing usability of a user.

A first information processing device according to an embodiment of the technology includes a communication section performing communication with other devices on a network, and an image generation section generating image information representing three kinds of information for each of contents. Specifically, the three kinds of information includes (1) address information of contents held by any of the other devices on the network or by the information processing device, (2) network identification information for authenticating participation of a wireless device to a wireless network configured to include an access point on the network, and (3) process instruction information set for each of the contents. The first information processing device further includes a display request section requesting a display device to display, on a screen thereof and together with a content list, the image information generated by the image generation section.

As used herein, the term device refers to a physical or logical entity which is independent and is capable of communicating with other devices in a network environment. The term content refers to a bundle of information sensed by a person through viewing, such as news, movies, dramas, television programs, music, images, photographs, videos, games, and animations. The term authentication means a process to identify a wireless device in order to allow access to a network.

In the first information processing device according to the embodiment of the technology, the communication section may capture the network identification information from a registrar-function implemented device on the network. Examples of the registrar-function implemented device include an access point. The access point is a device allowing a wireless device to access to a network, and example thereof is a Wi-Fi router. Note that the registrar refers to a logical entity having an authority for issuance and cancellation of the identification information, and the registrar is capable of being integrated into any devices including the access point. In addition, when any of the other devices on the network holds the content, the communication section may capture the address information and the process instruction information from the device. On the other hand, when the first information processing device according to the embodiment of the technology holds the content and the process instruction information in a storage region, the image generation section may read the information from the storage section.

In the first information processing device according to the embodiment of the technology, the network identification information includes, for example, a name of the wireless network and a passcode used for accessing to the wireless network. For example, the passcode is generated by the registrar-function implemented device, and is preferably generated for each of the contents. In addition, in the first information processing device according to the embodiment of the technology, the image information is, for example, a QR code (registered trademark of Denso Wave Inc.).

A first information processing program according to an embodiment of the technology is an information processing program for a device on a network capable of performing communication with other devices on the same network. The first information processing program allows the device to execute the following two steps:

(A1) a step of generating image information for each of contents stored in another device on the network or in the information processing device itself, with use of address information of the contents, network identification information, and process instruction information provided for each of the contents, the image information representing the three kinds of information, and the network identification information being used for authentication which allows a wireless device to participate in a wireless network configured to include an access point on the network; and

(A2) a step of requesting a display device to display, on a screen thereof and together with a content list, the image information generated by the image generation section.

In the first information processing device and the first information processing program according to the embodiments of the technology, the image information representing the network identification information and the like is generated for each of the contents, and the display device is requested to display the generated image information together with the content list on a screen. Therefore, the display device displays the image information representing the network identification information and the like, together with the content list on the screen.

At this time, for example, it is assumed that a user of the first information processing device (hereinafter, simply refer to as a user) thinks of copying one content in a content list to a wireless device (for example, personal computers, consumer electronics, mobile terminals, digital cameras, or mobile phones) owned by the user. In this case, the user captures the image information arranged corresponding to the content with use of a camera provided on the wireless device, captures the information represented by the image information, allows the wireless device to output the captured information to the wireless network, thereby capturing the content. At this time, the user recognizes only that the user presses a button of the wireless device several times to capture the image information and capture the desired content. In practice, in the background, as will be described below, a predetermined registration protocol and content transfer are performed between the access point and the wireless device.

For example, first, when information output from the wireless device to the wireless network is received by the access point on the network, the access point performs authentication with use of the network identification information included in the received information. If the authentication is successful, key exchange is performed between the access point and the wireless device, and the setting information such as wireless parameters is transferred from the access point to the wireless device. Next, the wireless device uses the captured setting information such as wireless parameters to access to the wireless network. By performing such a registration protocol, the wireless device becomes possible to perform normal data communication with use of an encryption key common to the access point. After that, the wireless device outputs the address information and the process instruction information which has been captured from the image information to the wireless network. Then, the device corresponding to the address information on the network receives the information from the wireless device to perform processing according to the process instruction information included in the received information. When the process instruction information indicates transfer of a copy of a content corresponding to the address information to the wireless device, the device transfers the copy of the content corresponding to the address information to the wireless device. As a result, the wireless device captures the copy of the content corresponding to the address information. In this way, the content transfer is performed.

A second information processing device according to an embodiment of the technology is an information processing device connecting a wireless device to a network. The second information processing device includes a receiving section receiving a wireless signal including three kinds of information from the wireless device, and a transmitting section transmitting, when any of the other devices on the network requests second network identification information for authenticating participation of the wireless device to the wireless network, the second network identification information to the device which has requested the second network identification information. Specifically, the above-described three kinds of information indicates (1) address information of a first content stored in a first device on the network, (2) first network identification information for authenticating participation of the wireless device to the wireless network of an access point on the network, and (3) process instruction information for the first content. In addition, the second network identification information transmitted by the transmitting section is issued by the transmitting section or is captured from a registrar-function implemented device on the network. The second information processing device according to the embodiment of the technology further includes an authentication section authenticating access of the wireless device, which has transmitted a wireless signal, to the network when the first network identification information is coincident with the second network identification information or when the first network identification information and the second network identification information have a predetermined relationship.

In the second information processing device according to the embodiment of the technology, when the wireless signal including the network identification information and the like is received from the wireless device, whether the first network identification information included in the received information is coincident with the second network identification information transmitted to any of the other devices on the network in past times or whether the first network identification information and the second network identification information have a predetermined relationship is examined. As a result, when the first network identification information is coincident with the second network identification information or when the first network identification information and the second network identification information have a predetermined relationship, the wireless device which has transmitted the wireless signal is allowed to access to the network.

If the authentication is successful as described above, for example, key exchange is performed between the second information processing device and the wireless device, and the setting information such as the wireless parameters is transferred from the second information processing device to the wireless device. Next, the wireless device uses the captured setting information such as wireless parameters to access to the wireless network. By performing such a setting protocol, the wireless device becomes possible to perform normal data communication with use of an encryption key common to the second information processing device. After that, the wireless device outputs, to the wireless network, the address information and the process instruction information which have been captured from the image information. Then, the device corresponding to the address information on the network receives the information from the wireless device through the second information processing device to perform processing according to the process instruction information included in the received information. When the process instruction information indicates transfer of a copy of a content corresponding to the address information to the wireless device, the above-described device transfers the copy of the content corresponding to the address information to the wireless device through the second information processing device. As a result, the wireless device captures the copy of the content corresponding to the address information. In this way, the content transfer is performed.

According to the first information processing device and the first information processing program of the embodiments of the technology, since the image information representing the network identification information and the like is displayed together with the content list on the screen, only a person near the display screen on which the image information is displayed may capture the image information using the wireless device with a camera, access the wireless network using the captured image information, and capture the content. The wireless device is not necessary to be a specific device such as a pre-registered device as long as the device has a camera and a function to access to the wireless network. In addition, in the technology, it is not necessary to press a button of the access point or to perform any setting operation on the access point. Therefore, even if the wireless device is located away from the access point, the wireless device may access to the wireless network, and the access point may be located at a place beyond the reach of a person, for example, under the roof. Accordingly, in the technology, wireless network connection may be performed safely without impairing usability of the user.

According to the second information processing device of the embodiment of the technology, in the case where the wireless signal including the network identification information is received from the wireless device, when it is determined that the first network identification information included in the received information is coincident with the second network identification information transmitted to any of the other devices on the network in past times, or when it is determined that the first network identification information and the second network identification information have a predetermined relationship, the wireless device which has transmitted the wireless signal is allowed to access to the network. Therefore, for example, the image information representing the network identification information and the like is displayed together with the content list on a screen of the device on the network, the image information is captured by the wireless device with a camera which is owned by a person near the display screen where the image information is displayed to access to the wireless network with use of the captured image information, and thus the content is obtainable. Here, the wireless device is not necessary to be a specific device such as a pre-registered device as long as the device has a camera and a function to access to the wireless network. In addition, in the technology, it is not necessary to press a button of the access point or to perform any setting operation on the access point. Therefore, even if the wireless device is located away from the access point, the wireless device may access to the wireless network, and the access point may be located at a place beyond the reach of a person, for example, under the roof. Accordingly, in the technology, wireless network connection is safely achievable without impairing usability of the user.

It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the technology as claimed.
