Description

  The present invention relates to a screen sharing server, a screen sharing system, and a screen sharing method.

  In recent years, home appliances such as digital televisions can be connected to a network and browse still images and moving images. There is also a service for uploading personal image data and the like to a server on the network and accessing the server when necessary to browse the image data and the like. In order to access such a server, authentication processing is usually performed using a user ID or password so that only image data that the user has the authority to access can be viewed. Therefore, various mechanisms for using such services not only with conventional personal computers and mobile phones but also with home appliances such as digital televisions have been considered.

For example, to transfer the device ID to the portable telephone terminal from the information appliance terminal, a method of sending from the mobile telephone terminal and the user ID and the device ID to the authentication server performs authentication has been disclosed (e.g., Patent Documents 1).
JP 2005-323070 A

  However, when acquiring content with restricted access at the information home appliance, when the server on the network provides the content, it is necessary to transmit a session ID for authenticating the information home appliance to the information home appliance. There are cases where information appliances do not have a cookie (HTTP cookie) used for user identification, session management, and the like. In such a case, there is a problem that user authentication cannot be performed.

  In addition, there is a problem that the screen of one information home appliance cannot be displayed by another information home appliance, not only when the information home appliance outputs a screen acquired on the network.

  Therefore, the present invention can perform user authentication even for information home appliances that do not have a cookie, and display the screen on other information home appliances, including the screen of the screen acquired with one information home appliance. An object is to provide a screen sharing server, a screen sharing system, and a screen sharing method.

  The present invention provides the following solutions.

(1) Connected to a mobile electronic device (for example, a later-described portable electronic device 30) and an information home appliance (for example, a later-described information home appliance 10) via a communication line (for example, an external network 40 and an internal network 90 described later) A session identifier generating means (for example, a session ID generating means 211 described later) for generating a session identifier (for example, a session ID described later) for identifying a session with the information home appliance, and the session identifier generating means session identifier transmitting means for transmitting the generated session identifier to the information home appliance (e.g., a session ID transmission unit 212 to be described later) and the a information transmitted by the portable electronic device, the session identifier and the user A user including an identifying user identifier (for example, a user ID described later). The authentication information (e.g., session ID will be described later, a device ID, user ID, password) and user authentication information receiving means for receiving (e.g., user authentication information receiving unit 213 to be described later), received by said user authentication information receiving means the user authentication information and the authentication means for performing authentication of the user based on the session identifier generated by the session identifier generating means (e.g., authentication means 214 to be described later), the portable electronic device or the screen from the information home appliance ( For example, based on screen request receiving means (for example, screen request receiving means 215 described later) for receiving a request for a screen described later and device identification information for identifying the portable electronic device or the information home appliance, the portable electronic device A screen for displaying the screen of the device or the information home appliance on another portable electronic device or information home appliance Storage means for storing shared information (e.g., memory unit 220) and, based on the stored the screen sharing information in the storage means, the portable electronic displaying the portable electronic device or screen is requested from the information home appliance A specifying unit (for example, specifying unit 216 described later) for specifying a device or the information home appliance; a screen acquiring unit (for example, screen acquiring unit 217 described later) for acquiring a screen of the portable electronic device or the information home appliance; it comprises a transfer means for transmitting to display output the screen acquired by the screen obtaining unit to the portable electronic device or the information home appliance identified (e.g., below the transfer means 218) by said specifying means A screen sharing server (for example, an authentication server 20 described later).
