Abstract: A method for visually authenticating photos comprises: calculating a first digital signature based on photo data corresponding to a photo to obtain first signature data, and storing the first signature data; and when a picture is displayed, implementing signature verification based on the picture data corresponding to the picture and the first signature data, and displaying an authentic mark with the picture when the signature verification succeeds. An apparatus for creating and assigning photos and an apparatus for visually authenticating photos are also disclosed.

Abstract: A method for managing closeness of a connection in SNS is provided and includes: calculating an intimacy distance of a connection based on times of activities or amount of interactions between a user and the other end of the connection, tuning the intimacy distance by other factors the user chooses; controlling the closeness of a connection and in disclosure according to the intimacy distance calculated. With the embodiments of the present invention, a user can control the closeness of a connection and control data disclosure based on the closeness with individual people regardless of their groups or circles.

Abstract: A method for generating a real time attribute mark of a picture comprises: extracting a first time from picture data corresponding to the picture; obtaining a current time; calculating a time interval between the first time and the current time; and generating a real time attribute mark indicating the time interval. An apparatus for generating a real time attribute mark of a picture is also disclosed.

Abstract: In general, techniques are described for modifying control plane messages for subscriber sessions with a network device to add and/or modify discrete information elements and thereby conform the messages to different versions of mobile network specifications, including roaming protocols, executed by different mobile networks or by heterogeneous infrastructure elements within a mobile network. In some examples, an input network interface of a network device receives a roaming protocol message on an interface connecting a first support node of a first mobile network and a second support node of a second mobile network. A roaming protocol module of the network device modifies the roaming protocol message by adding or modifying a discrete information element to conform the roaming protocol message to a roaming protocol of the second mobile network. An output network interface of the network device sends the modified roaming protocol message to the second support node.
