  • Patent number: 9398040
    Abstract: Disclosed herein is an Intrusion Detection System (IDS) false positive detection apparatus and method. An IDS false positive detection apparatus includes a payload extraction unit for extracting payloads by dividing each packet corresponding to an IDS detection rule into a header and a payload. A false positive payload information generation unit generates false positive payload information required to identify a false positive payload by extracting a payload of a false positive packet based on results of packet analysis received from a manager. A false positive payload determination unit transmits results of a determination of whether each payload extracted by the payload extraction unit corresponds to a false positive payload, based on the false positive payload information, to the manager.

  • Publication number: 20160149951
    Abstract: A secure transmission method and system that can reduce the channel capacity of an eavesdropper even in an environment in which there is no direct path between a source and a destination. In the secure transmission method, all of a plurality of relays between a source and a destination receive a transmission signal including first artificial noise from the source, and decode the transmission signal. All the relays forward decoded signals to the destination. The source outputs second artificial noise while all the relays are forwarding the decoded signals to the destination. The second artificial noise is received only by an eavesdropper.

  • Patent number: 9323987
    Abstract: An apparatus and method for detecting forgery/falsification of a homepage. The apparatus includes a homepage image shot generation module for generating homepage image shots of an entire screen of an accessed homepage. A character string extraction module extracts character strings from each homepage image shot using an OCR technique. A character string comparison module compares each of the extracted character strings with character strings required for determination of homepage forgery/falsification, thus determining whether the extracted character string is a normal character string or a falsified character string. A homepage falsification determination module determines whether the corresponding homepage has been forged/falsified, based on results of the comparison. A character string learning module learns the character string extracted from the homepage image shot, based on results of the determination, and classifies the character string as the normal character string or the falsified character string.

  • Publication number: 20160065600
    Abstract: An apparatus and method for automatically detecting a malicious link. The apparatus includes a threat information collection unit, a priority management unit, a malicious link collection unit, a malicious link analysis unit, and a malicious link tracking unit. The threat information collection unit collects threat information, and identifies whether a malicious link is present in each target site. The priority management unit determines the priorities of the target sites, and performs the assignment and management of the target sites in order to collect and analyze a malicious link. The malicious link collection unit collects the uniform resource locator (URL) of the malicious link from the target sites. The malicious link analysis unit analyzes a call correlation based on the collected URL, and analyzes the malicious link through pattern matching. The malicious link tracking unit tracks the real-time changing state of the malicious link.

  • Patent number: 8094013
    Abstract: A baby monitoring system for remotely monitoring a child's breath rate and body orientation is disclosed. The system comprises, in one embodiment, a parent unit retained by a supervisor, a sensor unit removably engaged around the child's abdomen, and a nursery unit positioned proximal the child, preferably in the same room. The sensor unit provides at least two tri-axial accelerometers positioned and configured such that each is independently capable of measuring both the child's breath rate and body orientation, even where the child's body is oriented such that movement of at least one of the accelerometers is restricted. The sensor unit then wirelessly transmits this information to the nursery unit, which performs necessary calculations and transmits this data to the parent unit, which displays the data on a display screen. Additionally, the system is capable of recording and reproducing a heart beat sound of the child's mother.
