Abstract: An alcohol consumption determination method includes: detecting an effective frame of an input voice signal; detecting a difference signal of an original signal of the effective frame; performing fast Fourier conversion on the original signal and the difference signal; and determining, in the frequency domain, whether alcohol has been consumed based on a slope difference between the fast-Fourier-transformed original signal and the fast-Fourier-transformed difference signal. Accordingly, it is also possible to determine whether a driver or an operator from a remote location has consumed alcohol and a degree of the consumption, thus preventing an accident caused by an individual operating a vehicle under the influence.

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.
