  • Patent number: 11323560
    Abstract: An illegal call detection apparatus comprises a data collecting unit, a preprocessing unit, and a learning unit. The data collecting unit collects, from at least one of a subscriber terminal or a call exchanger, a raw packet generated by the subscriber terminal using a VoIP service, and collects, from the billing server, CDR data related to the raw packet. The preprocessing unit generates learning data by using service usage information extracted from the CDR data and service detailed information extracted from the raw packet, and generates a training image by converting the training data into an image according to a predetermined imaging rule. The learning unit extracts at least one or more features from the training image, and learns whether the training image is related to an illegal call by using the features, through an illegal call detection model.

  • Patent number: 8245299
    Abstract: A method and apparatus for monitoring a code to detect intrusion code is used to monitor target code to determine whether the target code is a resident code in a system or an intrusion code into the system. A first code pattern is extracted from the target code and a second code pattern is loaded from a storage unit, and a distance between the first code pattern and the second code pattern is calculated. The calculated distance is compared to a threshold to determine whether the target code is an intrusion code.
