Summary:PROBLEM TO BE SOLVED: To execute accurate filtering in a short processing time in response to a connection request to the Internet.SOLUTION: In a filtering device 100, when a connection request from a user terminal 200 to the Internet 300 is made, a destination URL is converted into a hash value for performing high speed determination (collation), and when it is determined that the hash value is not present (it is determined that the destination URL is a filtering object candidate), determination (collation) is performed by using the destination URL as it is. Thus, it is possible to achieve accurate filtering in a short processing time.
