Abstract: Software defined network (SDN) for preventing an attack on a host tracking service and a controller included in the same are disclosed. The SDN comprises a plurality of switches arranged on a data plane of the SDN, and connected to at least one host, and a controller arranged on a control plane of the SDN, configured to control the switches and perform a host tracking service for recognizing location of at least one host connected to the switches. Here, a switch A of the switches receives a packet from a host A connected to the switch A and transmits an address information message of the host A to the controller based on the packet. The controller determines whether or not the host A is a host for performing an attack on the host tracking service, by using the address information message and previous address information of the host.

Abstract: A method of preventing priority inversion in power line communication includes generating a priority notification signal of each node in order to prioritize a packet transmitted by each of the nodes, decreasing carrier detection threshold value of a prioritization section in the priority notification signal of each of the nodes, increasing transmission power level of the prioritization section in the priority notification signal of each of the nodes, transmitting the priority notification signal generated by each of the nodes, prioritizing the nodes by comparing the prioritization sections of the priority notification signals, and preferentially transmitting a packet of a node with a higher priority. This can solve a priority inversion problem between signals in a network to safely transmit signals without collisions and latency.

Abstract: This method for determining alcohol use comprises the steps of: detecting an effective frame in an input audio signal; detecting a difference in signal within the original signal of the effective frame; performing a fast Fourier conversion on the difference signal to be transformed into a frequency domain; detecting high-frequency components within the difference signal subjected to the fast Fourier transform; and determining the state of alcohol use on the basis of a gradient difference between the high-frequency components. Accordingly, the present invention can identify the state and extent of alcohol use by a driver or an operator from a long distance and thus can prevent accidents caused by driving or operating vehicles and machines under the influence of alcohol.

Abstract: Provided are a harmful site collection device and method for determining a harmful site by analyzing a connection between harmful sites. The harmful site collection device extracts a URL linked to a web page of a harmful site; checks a link circulation on the basis of link information on a web page of the URL linked to the harmful site to determine whether the web page of the URL linked to the harmful site is a harmful site; and, when a URL of a prestored non-harmful site is extracted while the link circulation is checked, stops checking the link circulation that includes the URL of the non-harmful site. Accordingly, the harmful site collection device can more easily determine a harmful site merely with information on a URL linked to a web page and can reduce the amount of computation using information on a URL of a prestored non-harmful site.
