A method of and an apparatus for sorting data traffic based on a predetermined priority such as a bandwidth and a liveliness is provided. The method includes operations of: receiving the data flows; sorting the data flows based on bandwidth by defining a plurality of bandwidth ranges and classifying the sorted data flows according to the bandwidth ranges to which the bandwidth of each data flow belongs; and sorting the classified data flows based on liveliness representing frequency of occurrence of the data flows. The sorting of the classified data lows determines that the data flow which is recently received has the higher liveliness and sorts the data flows based on the determination. The method and apparatus facilitates selecting data flows which are possible hostile attack attempts from a vast amount of data traffic and allowing selective and intensive monitoring of the selected data flows.

User/service authentication methods and apparatuses using split user authentication keys are provided. A user authentication key is generated using user's personal information including an identification number and bio information, the generated user authentication key is split into a plurality of keys, and a request for authentication of a user that uses a first user authentication key provided to the user from among the plurality of split user authentication keys is authenticated using the other user authentication keys. After the authentication is successful, a service authentication is performed according to a result obtained by recombining the split user authentication keys, so that when some of distributed service authentication keys are lost or stolen, since original user authentication information cannot be restored, user information is prevented from being exposed, damage caused by a lost or stolen authentication key owing to double authentication is reduced, security protection is reinforced using a security channel formed through the service authentication, and communication exchanges such as electronic commerce over Internet are safer.

Provided are a key authentication/service system and method using one-time authentication code. In the system and method, a key management client sends a key management server a message requesting transmission of a message for generating authentication code required to request a key management service. Next, the key management server creates a challenge message based on a challenge/response method using the received message. Next, the key management client generates the one-time authentication code using the challenge message and transmits it along with a message requesting a key management service to the key management server. Next, the key management server receives the one-time authentication code from the key management client and checks whether the one-time authentication code is certified to determine whether the key management client has a right to use the key management service. Then, the key management server provides the key management service to the key management client when it is determined that the key management client has a right to use this service.

A prefiltering method and apparatus for prefiltering a data stream for pattern matching are provided. The prefiltering method includes: receiving a data stream; loading previously stored filtering policies; filtering the data stream according to the loaded filtering policies and generating additional filtering information regarding the filtered data stream; determining whether to transmit the data stream to a search engine apparatus that performs pattern matching based on the additional filtering information; and transmitting the data stream to the search engine apparatus if the data stream is determined as requiring transmission. Therefore, it is possible to provide a high-performance pattern matching system that can achieve a high precision of pattern matching.

The present invention relates to an anisotropic conductive adhesive comprising an anisotropic conductive adhesive combined with a crystalline polymer to realize anisotropic conductivity and PTC (Positive Temperature Coefficient) characteristics at the same time. The anisotropic conductive adhesive having PTC characteristics according to the present invention comprises an insulating adhesive component and a plurality of conductive particles dispersed in adhesive component, in which the insulating adhesive component comprises a crystalline polymer. Since the anisotropic conductive adhesive according to the present invention includes a crystalline polymer, when temperature rises and the volume expands, electrical resistance is rapidly increased, whereby current flow is intercepted resulting in blocking current, providing PTC characteristics acting as a switch. Thus, it shows circuit protection function as well. Accordingly, it is possible to intercept a circuit upon occurrence of excess current without using a separate element for circuit protection such as PTC thermistor.

The invention relates to a nitride semiconductor LED and a fabrication method thereof. In the LED, a first nitride semiconductor layer, an active region a second nitride semiconductor layer of a light emitting structure are formed in their order on a transparent substrate. A dielectric mirror layer is formed on the underside of the substrate, and has at least a pair of alternating first dielectric film of a first refractivity and a second dielectric film of a second refractivity larger than the first refractivity. A lateral insulation layer is formed on the side of the substrate and the light emitting structure. The LED of the invention effectively collimate undesirably-directed light rays, which may be otherwise extinguished, to maximize luminous efficiency, and are protected by the dielectric mirror layer formed on the side thereof to remarkably improve ESD characteristics.

Provided are an apparatus and method of protecting a user's privacy information and corporate intellectual property against a denial-of-information (DoI) attack, and more particularly, a privacy & intellectual property protection framework (PIPPF) and a network-based privacy & intellectual property protection system (NPIPPS). The PIPPF includes the NPIPPS and an integrated identity access and management (IAM)/network access control (NAC) solution. The NPIPPS monitors inbound and outbound contents at the network level and prevents the leakage of important information. In addition, the integrated IAM/NAC solution prevents abnormal user activity within a network and unauthorized use of information.

A method and apparatus for generating discriminant functions for distinguishing obscene videos by using visual features of video data, and a method and apparatus for determining whether videos are obscene by using the generated discriminant functions, are provided. The method of generating discriminant functions includes: creating a first frame set by extracting a predetermined number of frames for each video data unit from a group of video data classified as obscene or non-obscene, and creating a second frame set by selecting the frames; generating a frame based discriminant function by extracting visual features of frames of the second frame set, and then generating a first discriminant value by determining whether each frame of the first frame set contains obscene video data; generating a group frame based discriminant function by extracting visual features of a group of frames of the first frame set, and then generating a second discriminant value by determining whether the frames of the group contain obscene video data; and generating a synthetic discriminant function by using the first and second discriminant values as a representative value of the video data. Accordingly, obscene video data stored in a computer system can be automatically and accurately distinguished.
