In modern society, there exist many different types of authentication processes that we are unaware of not only in IT fields but also in our daily lives. Many recent issues of cyber crimes target weak passwords or careless management of passwords. This fact proves the importance of user authentication. In this paper, a secure user authentication scheme using smart cards in IPTV and also offer, by using smart cards and bio information to ensure strong security and a secure user authentication scheme is proposed. We propose extended model of "Fingerprintbased access control using smart card in IPTV" suggested in the previous work. We can extend our scheme to provide contents to subscribers according to an attribute of a subscriber instead of an age by modifying the function in the registration phase. And we analyzed the security of our proposed scheme about caused by malicious attacks.
