  • Patent number: 10380244
    Abstract: The present disclosure includes a memory in which a content providing program is stored, and a processor that executes the program stored in the memory. Herein, upon execution of the program, the processor extracts a subject and a verb property including multiple verbs corresponding to the subject from a target content, infers a verb-form subject of the target content on the basis of the subject and the verb property, and extracts one or more contents matched with the target content from among multiple candidate contents on the basis of the verb-form subject of the target content. Further, the multiple verbs corresponding to the subject are extracted from an associative verb group.

  • Publication number: 20070143845
    Abstract: Provided are a method and system for preventing personal information of a user using server registration information and an authentication system connected to the Internet. The method includes collecting information regarding servers which provide an Internet service; classifying the safety of sites using the servers based on the information; and providing site information containing the information regarding the servers at the request of a client which tries to access the servers. In the method, addresses of servers of major organizations connected to a network are registered in advance. Therefore, when a terminal of a user tries to access an external site through the network, it is possible to identify which organization has actually registered an address of the site and determine whether the site is a harmful site. If the site is determined to be harmful, the access to the site is blocked, thereby preventing the damages of phishing.

  • Publication number: 20070136139
    Abstract: 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.

  • Publication number: 20050190304
    Abstract: Disclosed herein is RF modulator with a narrow bandpass filter. The RF modulator for modulating video and audio signals into RF signals corresponding to a frequency band of a predetermined channel includes an oscillation unit for generating a predetermined RF signal suitable for the frequency band of the predetermined channel; a mixer for modulating the video and audio signals using the RF signal generated from the oscillation unit; and a narrow bandpass filter for receiving an RF-modulated signal from the mixer, and passing only a signal of the frequency band of the predetermined channel from among the RF-modulated signal. Therefore, the RF modulator can remove or block unnecessary components such as lower side band and harmonic-frequency signals generated after video and audio signals have been RF-modulated, such that it can prevent interference between channels from being generated, resulting in the creation of more excellent video and audio signals.

  • Publication number: 20050089740
    Abstract: The present invention relates to a solid oxide fuel cell for internal reforming of hydrocarbons and carbon dioxide, in particular, to a solid oxide fuel cell in which one side of solid oxide electrolyte (YSZ) is attached to an air electrode (La0.8Sr0.2MnO3) and its other side is attached to a catalyst electrode of Ni-YSZ type or perovskite type metal oxide. The electrochemical conversion system using the solid oxide fuel cell permits the occurrence of internal reforming of hydrocarbons and carbon dioxide concomitantly with the coproduction of a syngas and electricity, and overcomes the shortcomings associated with the catalytic deactivation due to carbon deposition and the high-energy consumption.
