User terminal, unauthorized site information management server, and method and program for blocking unauthorized request

摘要

The transmission of an unauthorized request from a terminal is blocked. It is possible to provide a user terminal which blocks an unauthorized request made by malicious content by detecting the transmission of a request generated in a user terminal, investigating whether the request contains an improper word registered in an improper word database, and inhibiting the transmission of the request when it is determined that the request contains the improper word.
