CA 2596948

There is provided a technique for increasing safety of access to a content. A virus/fishing site list (161) holds a list of URL of fishing sites for acquiring personal information such as a card number, a personal identification number, and a password in an unauthorized way by giving an appearance as an authorized site. When a communication control unit (2) receives a packet containing communication data for requesting an access to a content via a network, a search circuit (30) compares the URL of the content of the access destination contained in the communication data to the URL of the fishing site contained in the virus/fishing site list (161). If the address of the content of the access destination is matched with the URL of the fishing site, a processing execution circuit (40) inhibits the access to the content.

La présente invention décrit une technique permettant d~accroître la sécurité d~accès à un contenu. Une liste de virus /de sites de phishing (161) répertorie une liste d~URL de sites de phishing visant un accès non-autorisé à des informations personnelles telles qu~un numéro de carte, un numéro personnel d~identification, et un mot de passe en prenant l~apparence d~un site autorisé. Lorsqu~une unité de contrôle des communications (2) reçoit un paquet de données contenant des informations de communication demandant un accès à un contenu par le biais d~un réseau, un circuit de recherche (30) compare l~URL du contenu de la source à laquelle on veut accéder apparaissant dans les informations de communication à l~URL du site de phishing figurant dans la liste des virus/des sites de phishing (161). Si l~adresse du contenu de la source à laquelle on veut accéder correspond à l~URL du site de phishing, un circuit d~exécution du processus (40) bloque l~accès au contenu.
