PURPOSE: A method for generating a spam message classifier in a social network site by using a relation between a transmitter and a receiver, a device thereof, and a spam message filtering method thereof are provided to accurately filter the spam message by checking if a message is a spam or not through relation information between the receiver and transmitter of the spam message. CONSTITUTION: A spam message classifier generating device collects a real message transceived between members from a specific Internet social network site(S210). The device checks whether the collected message is a spam message(S220). The device calculates a connection degree and a relation distance of a transmitter and a receiver of the message(S230). The device generates a spam message classifier by using features derived from the calculated message(S240).

Abstract:
PURPOSE: A user location information protection method and a system thereof are provided to approximately track a first portable terminal of a user for a second portable terminal of the user without exposing an exact location of the first portable terminal of the user. CONSTITUTION: A transmission/reception unit(113) receives location information of a user from a first portable terminal of the user. A detection unit(133) detects location semantic using duration and time context. The duration shows a time period of the user in a specific location for more than predetermined time according to the location information of the user. The time context is a time period where the user is busy in the specific location. A generation unit(153) generates a semantic graph based on the location semantic.

Abstract:
PURPOSE: A method for effectively saving consumption power in a wireless lan device when using a mobile ip storage and a mobile terminal for executing the same are provided to store a fixed amount of data received through a wireless LAN in a first input buffer and convert a wireless LAND device during time for consuming the data into a low power mode, thereby changing power efficiency of the mobile terminal. CONSTITUTION: A first input buffer(126) inputs/outputs data for an IP storage device(200). A first input buffer controller(125) controls first input of the data for the first input buffer. The first input buffer controller measures first input speed and data consuming speed. The first input buffer controller determines the size of the first input buffer according to a parameter.
Abstract:
PURPOSE: A WLAN device power control method for low power mobile IP storage for converting low power mode is provided to reduce power consumption by converting a WLAN device into low power mode when receiving data through network. CONSTITUTION: A data is received from an IP(Internet Protocol) storage server. If the data is stored to the critical capacity of a prefetch buffer of a mobile terminal, the prefetch of the data is interrupted(S7). After interrupting the prefetch of the data, a WLAN(Wireless Local Area Network) device is maintained in a power saving mode(S8). The data stored in the prefetch buffer is consumed in an application program(S9). If the data stored in the prefetch buffer approaches, the WLAN device receives data in the active mode(S10).

Abstract:
Disclosed is a technology relating to an apparatus and a method for user authentication on a mobile platform. The apparatus for user authentication comprises: an information generating unit which generates usage pattern information based on application usage information received from an application which is used in a terminal of a user, and which generates user situation information based on situation information received from at least one sensor sensing circumstance information of the terminal; and an authentication processing unit which generates an authentication result by comparing the usage pattern information and the user situation information with information of a preset authentication policy, and which determines whether or not to process an additional authentication. According to the present invention, the convenience of a user of the terminal can be improved and a mobile terminal can be used more efficiently if the apparatus and method for user authentication on the mobile platform are used.
Abstract:
PURPOSE: A virtual environment management method and a terminal using the same are provided to separately drive a virtual smart phone, thereby driving an application program in a different VM(Virtual Machine) of the virtual smart phone. CONSTITUTION: When situation information causes the change of a virtual environment, VMs(100_1,100_2) receive the situation information and provides the situation information to a hypervisor(200). The hypervisor determines the virtual environment corresponding to the situation information and changes a driving environment which is provided by a VM. The hypervisor changes a situation of the VM into one of an execution state, a stop state, and an end state. The hypervisor changes the situations of a part of VMs into the end state or the stop state and changes the situations of the remaining VMs into the execution state.

PURPOSE: An authentication method at an IPTV system and set top box for the same are provided to reduce a packet delay time and a packet loss. CONSTITUTION: An IGMP(Internet Group Management Protocol) message is created(610). By using RC(Remode Controller)-5 algorithm, a pseudo-random number is generates as a weak authentication trailer(620). A set top box generates an HMAC value of 128 bit by using MD(Message-Digest)-5 alogrithm(630). The weak authentication trailer and a strong authentication trailer is inserted to the IGMP packet(640). The IGMP packet is transmitted(650).
