摘要:
A Peer-to-Peer (P2P) based social networking service method for providing a social networking service, includes transmitting a request to a peer group and performing a group-based social networking service; transmitting news or a question to peers in the peer group, and then receiving a response to the question; and storing the received information in a storage medium, and uploading specific information among the stored to a rendezvous peer. The method further includes delivering the uploaded specific information to another rendezvous peer in a network. A P2P based social networking service system includes a P2P middleware unit for providing services of communicating between and grouping the peers; a P2P service application program interface layer for providing a network element function; and a P2P application service layer for calling the network element function, if required, to thereby provide a user with a P2P based network service.

A method of creating a security group over a Peer-To-Peer (P2P) network is disclosed. An invitee terminal attaches a public key to a peer advertisement in which its own identification information is encrypted using its own private key, and then sends a resulting peer advertisement over the P2P network. An inviter terminal, which has found the peer advertisement, encrypts a group advertisement, including group information about the security group, using public keys of the corresponding invitee terminal, and then sends a resulting group advertisement to the invitee terminal desired to be invited to the security group. The invitee terminal decrypts the group advertisement using its own private key, and participates in the security group using the group information.

An apparatus for multicasting contents between devices in different networks includes: a home-to-home multicast control device for finding the devices in the networks, downloading contents from a device in a network to which the home-to-home multicast control device belongs, processing the contents to generate file blocks, each file block having chunk files, and multicasting the processed contents to the devices in the networks; and at least one home-to-home multicast bridge device for receiving the contents transmitted from the home-to-home multicast control device and streaming the contents to one or more devices in a network to which the home-to-home multicast bridge device belongs. The apparatus further includes a multicast relay device for relaying the contents between the home-to-home multicast control device and the home-to-home multicast bridge device.
摘要:
An apparatus and method for automatically migrating user's working data by using automatic work data migration apparatuses connected respectively to work devices. In the method, the automatic work data migration apparatus detects that the user leaves or accesses the work device. User work data related to the work device are collected and the collected user work data stored in the automatic work data migration apparatus, if it is detected that the user leaves the work device. The storage location information of the user work data is provided to another automatic work data migration apparatuses connected to the automatic work data migration apparatus. The automatic work data migration apparatus searches the storage location information of the user work data if it is detected that the user accesses the work device. The automatic work data migration apparatus connected to the work device accessed by the user receives the user work data related to a work executed in the previous work device.

Provided are a multimedia play apparatus and method. The multimedia play apparatus and method enable synchronization between an audio and a video through existing multimedia play time information, and even in a multimedia service that simultaneously provides multimedia and a message, the multimedia play apparatus and method enable synchronization between multimedia and a message that occurs by terminal characteristics between different environments and different users on the basis of existing multimedia play time information and multimedia meaning information. Moreover, by performing synchronization between multimedia and a message on the basis of the multimedia meaning information, the multimedia play apparatus and method can prevent the damage of a multimedia service that provides multimedia and a message together because of a spoiler corresponding to a malicious message.
