Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of Invention  
           [0002]    The present invention relates generally to an authentication system. More particularly, the present invention relates to a fingerprint authentication system for accessing secured sites and apparatus having fingerprint verification capabilities thereof  
           [0003]    2. Description of Related Art  
           [0004]    It has become increasingly popular for users to remotely access public and private network for public use and business use, by using an artificial intelligent device through wired or wireless communication network. The information stored in the private network for business or personal use may include, but is not limited to, bank accounts, credit card numbers, addresses, commercial trade secrets, criminal records in characters, graphic images, moving pictures, sound, and animation. The artificial intelligent device may be provided with an Internet-based document management system and methods that allows user to access to services supported by a common Internet-based database, including storage of data, data sharing and document distribution. Further, the artificial intelligent device may be provided an Internet-based document management system and methods that allows the user to selectively filter electronic documents during storage to and retrieval from, an Internet-based storage site. Furthermore, the artificial intelligent device may be provided an Internet-based document management system and methods that allows users to collaboratively store, retrieve, modify and then return an electronic document to an Internet-based storage site. It is also further desirable to provide the artificial intelligent device a system for the construction and validation of access keys for use in an Internet-based document management system, where the access keys are not derived from user or resource information and can be used to control access to the services offered by the document management system. Still, further, the artificial intelligent device may be provided an Internet-based document management system and methods that enable the transaction logging and accounting functions needed for multi-user collaborative electronic document manipulation, for example, so that revisions to a document may be tracked. It also would be desirable to provide the artificial intelligent device an Internet-based document management system and methods that enable tracking of transactions performed on a document for billing purposes, and which provide needed access-control protocols.  
           [0005]    Therefore it is highly important to protect access to aforementioned services to any unauthorized users. Conventionally, a personal computer is coupled with an authentication software system that typically requires logging in identification name and password, which is verified to allow the authorized user to access the services. However, one problem is that the user may forget the password. Even in more serious situation, the password may be stolen without the knowledge of the user. Further, the procedure of keying in the identification name and the password is a time consuming process.
