Abstract: An anti-phishing method includes the steps of establishing an information center having a blacklist database, wherein the information center is liaising with at least an Internet service provider (ISP) through a communication network; collecting a plurality of phishing sources to be stored in the blacklist database to form a plurality of blacklist items therein; and sending the blacklist sources to the Internet service provider such that when a user of the Internet service provider tries to access a website source which matches with one of the blacklist items, the user receives a warning signal to inform the user that the website address is the phishing source.
