Abstract:
PURPOSE: A personal information leakage alarm system in cloud computing environment and a method designate a security level according to importance of a data file, manages data on a data basis, and thereby more effectively manages problems related to security of personal information. CONSTITUTION: A file registration unit (210) disperses/stores files into multiple chuck servers, and manages security level information of the file. A file search unit (220) receives a file access request from a client module, and confirms the security level information of the file corresponding to the file access request. In case the security level information of the file is above a pre-set level, the file search unit notifies an owner of the file of the file access request.

Abstract:
PURPOSE: A fountain code based video streaming system and a method thereof are provided to supply a seamless video streaming service by using a fountain code. CONSTITUTION: Fountain encoders(400,420) of transmitting devices(40,42) perform fountain encoding of source symbols. A fountain decoder(440) decodes a source symbols by fountain decoding of the fountain-encoded symbol. A pier selector(4440) of a controller(444) selects the peers with reference to a bandwidth of peers. A symbol size determinator(4442) determines the size of a symbol in consideration of a buffer state. The symbol size determinate changes the size of a symbol by recognition of data size of a video decoding buffer(442).

Abstract:
PURPOSE: A dynamic overlay network configuration system based on an ISN store is provided to supply an IPTV, a social network service and an individual broadcasting service. CONSTITUTION: A service information registration unit(310) registers service information of a service provider. An OT(Overlay Transport) reference and registration unit(330) obtains network OT resource information from an ISN(Intelligent Service Networking). A service network topology configuration unit(340) dynamically configures an overlay network. The service network topology configuration unit transfers overlay network information to a service user.
Abstract:
PURPOSE: An additional service providing apparatus and method using an open type profile are provided for third service providers to offer a differentiated personal recommended service. CONSTITUTION: A service management unit(111) operates and manages an IPTV service. A contents management unit(113) performs the reception and distribution of contents, the compression of a received video signal, or the encryption of the contents. A profile management unit(115) manages information used in the service management unit and the contents management unit. User terminals(131~133) reproduces compressed digital information delivered through an IPTV transmission network(120). The user terminal creates an inputted control signal.
Abstract:
PURPOSE: A context-aware system and method for real-time metering and billing various types of energy consumption are provided to collectively analyze the situation information on the object consuming energy by using a charging system. CONSTITUTION: According to received energy consumption, a charging system(110) calculates the charging amount for a charged target. A metering system(120) transfers to the charging system not only the energy consumption amount of the measured device but also the context information measured by a sensor node(140). The sensor node measures the condition information related to the use method of a user device. The measure terminal is attached to the device.
Abstract:
PURPOSE: A video transmitting system method, an audio receiving system and a method thereof are provided to solve a service blocking problem of a VoD(Video-on-Demand) which is available when burst or compensate a request about constant video by using unicast schema. CONSTITUTION: A video transmitting system(200) includes a multicast video determining unit(210), a video transmitting unit(220). The multicast video determining unit determines multicast among a plurality of videos based on requesting history about the video. The video transmitting unit multicasts the multicast video by allocating a multi-session.
