Relay server and relay communication system

Abstract: A relay communication system includes a relay server R that can communicate with a relay server R in another LAN through an external server S in a WAN. The relay server R stores account information of terminals T in the LAN, relay group information 100 on a group of relay servers R, and shared resource information 120 including a resource and accounts of the terminals T sharing the resource. The relay group information 100 and the shared resource information 120 include status information 107 and 127 indicating a status of the relay server R. The relay server R periodically performs an operation check to automatically update the status information 107 and 127.

The relay server includes an account information registering unit arranged to store account information including information of a client terminal connected to the same LAN; a relay group information registering unit arranged to store relay group information including information of a group of relay servers permitting connection with one another; a shared resource information registering unit arranged to store shared resource information including information of a resource and information of the client terminals sharing the resource; a relay processing unit arranged to, when accepting from the client terminal stored in the account information registering unit operation instruction on a resource operable by a client terminal connected to another LAN based on the shared resource information, relay the operation of the resource based on the relay group information; and a resource information providing unit arranged to, when accepting an access based on a predetermined protocol from an external client terminal, convert the shared resource information to a format of the predetermined protocol and providing the information to the external client terminal, the external client terminal other than the client terminal stored in the account information registering unit being registerable in the shared resource information registering unit.

File transfer server

Abstract: This invention provides a technique of allowing shared use of a file between different networks beyond the Internet. File transfer servers on different LANs access file servers on the respective LANs to prepare a list of shared files, respectively. The file transfer servers are registered in a SIP server, and then send a SUBSCRIBE method to each other to issue a request to transfer the file list, respectively. In response to the request, the file lists are exchanged. A communication terminal on each LAN makes a request to acquire a specific file on the basis of information about the shared files stored in the file transfer server. Through a media session, one of the file transfer servers issues a request to acquire the file to the other file transfer server; thus, the file is transferred to the communication terminal.

File server device, communication management server device, and network system including the file server device and the communication management server device

Abstract: A file server device includes a communication function using a call control protocol such as a SIP, a reply unit and an access accepting unit. When receiving an “INVITE” message, the reply unit returns a response message including information necessary for accessing an object stored in the file server device. The access accepting unit establishes a data session with a transmitter of the “INVITE” message and accepts access to the object stored in the file server device in the established data session.

Relay server and communication system

Abstract: PROBLEM TO BE SOLVED: To provide a communication system which can readily conduct connection between terminals within different local systems. SOLUTION: A terminal 11 logs in a relay server 4, and the terminal 11 updates the connection information and notifies the update to a relay server 5, when communication with the relay server 4 is available. Likewise, a terminal 21 logs in the relay server 5, and the terminal 21 updates the connection information and notifies the update to the relay server 4, when communication with the relay server 5 is available. When a connection request from the terminal 11 to the terminal 21 is transmitted to the relay server 4, the relay server 4 refers to the connection information to estimate the connection state of the terminal 21, and the fact that the terminal 21 is connected to the relay server 5. If the terminal 21 can be communicated, the relay server 4 transfers the connection request to the relay server 5, and then the relay server 5 transfers the transferred connection request to the terminal 21. Hereinafter, the relay servers 4 and 5 relay communications between the terminal 11 and the terminal 21.

Unlocking a device by performing gestures on an unlock image

Abstract: A device with a touch-sensitive display may be unlocked via gestures performed on the touch-sensitive display. The device is unlocked if contact with the display corresponds to a predefined gesture for unlocking the device. The device displays one or more unlock images with respect to which the predefined gesture is to be performed in order to unlock the device. The performance of the predefined gesture with respect to the unlock image may include moving the unlock image to a predefined location and/or moving the unlock image along a predefined path. The device may also display visual cues of the predefined gesture on the touch screen to remind a user of the gesture.

Embedded authentication systems in an electronic device

Abstract: An electronic device with a display and a fingerprint sensor may authenticate a user for a respective function. While a respective function of the device is in a locked state, the device displays a graphical element on the display, the graphical element indicating a first direction of finger movement that enables unlocking of the respective function. While displaying the graphical element, the device detects an input that includes movement of a finger in the first direction over the fingerprint sensor and determines whether the input meets unlock criteria based at least in part on fingerprint information of the finger detected by the fingerprint sensor during the input. In accordance with a determination that the input meets the unlock criteria, the device unlocks the respective function; and in accordance with a determination that the input does not meet the unlock criteria, the device maintains the respective function in the locked state.

Device, method, and graphical user interface for manipulating user interfaces based on fingerprint sensor inputs

Abstract: An electronic device with a display and a fingerprint sensor displays a fingerprint enrollment interface and detects, on the fingerprint sensor, a plurality of finger gestures performed with a finger. The device collects fingerprint information from the plurality of finger gestures performed with the finger. After collecting the fingerprint information, the device determines whether the collected fingerprint information is sufficient to enroll a fingerprint of the finger. When the collected fingerprint information for the finger is sufficient to enroll the fingerprint of the finger, the device enrolls the fingerprint of the finger with the device. When the collected fingerprint information for the finger is not sufficient to enroll the fingerprint of the finger, the device displays a message in the fingerprint enrollment interface prompting a user to perform one or more additional finger gestures on the fingerprint sensor with the finger.

Information processing apparatus, information processing method and program

Abstract: A method is provided for modifying an image. The method comprises displaying an image, the image comprising a portion of an object; and determining if an edge of the object is in a location within the portion. The method further comprises detecting movement, in a member direction, of an operating member with respect to the edge. The method still further comprises moving, if the edge is not in the location, the object in an object direction corresponding to the detected movement; and modifying, if the edge is in the location, the image in response to the detected movement, the modified image comprising the edge in the location.
