Abstract

A fingerprint-based network authentication method and system thereof comprises a user end and an authentication end. The user end has a fingerprint capture device comprising a fingerprint capture unit, a fingerprint processing unit, and a transmission unit. The fingerprint capture unit captures a fingerprint image, which is received and packaged into a data packet by the fingerprint processing unit. The transmission unit transmits the data packet. The authentication end has an authentication device comprising a transmission unit, a fingerprint processing and control unit, a data storage unit, and an interface unit. The transmission unit receives the data packet. The fingerprint processing and control unit receives and compares the data packet. The data storage unit stores fingerprint data and related user data. The interface unit transforms a comparison result into a control signal and replies the authentication result so as to authenticate the user's identity and confirm the limits of authority.

Dependent claims

A fingerprint-based network authentication system comprising:

a user end having a fingerprint capture device comprising a fingerprint capture unit, a fingerprint processing unit, and a transmission unit, wherein said fingerprint capture unit captures a user's fingerprint image, said fingerprint processing unit receives said fingerprint image captured by said fingerprint capture unit and packages said fingerprint image into a data packet defined by a self-described protocol with variable length (SPVL), and said transmission unit transmits said data packet formed by said fingerprint processing unit;
and
an authentication end for authentication and authorization, said authentication end having an authentication device comprising a transmission unit, a fingerprint processing and control unit, a data storage unit, and an interface unit, wherein said transmission unit receives said data packet transmitted from said transmission unit of said fingerprint capture device, and said fingerprint processing and control unit receives said data packet transmitted from said transmission unit and compares said data packet with a fingerprint minutia established in said data storage unit, wherein said data storage unit is connected with said fingerprint processing and control unit for storing fingerprint minutia data and related user data, and said interface unit transforms a comparison result of said fingerprint processing and control unit into a control signal and replies the authentication result so as to authenticate said user's identity and confirm the limits of authority by using said fingerprint minutia, thereby granting said user the right of use.

A fingerprint-based network authentication method in which a user end and an authentication end share an secret key, said authentication end sends out a effective time-dependent random number to said user end, said user end links up a user's fingerprint image, said secret key, and said effective time-dependent random number for forming a packet and sending back said packet to said authentication end, and said authentication end performs an operation so as to compare said fingerprint image, said secret key, and said effective time-dependent random number for authenticating said user, said fingerprint-based network authentication method comprising:

step one:
starting an authentication protocol by said user end;
step two:
asking said user end to input said fingerprint image by said authentication end;
step three:
capturing said fingerprint image by a fingerprint capture device of said user end;
step four:
sending said effective time-dependent random number to said user end by said authentication end;
step five:
performing said operation by said user end so as to link up said fingerprint image, said secret key, and said effective time-dependent random number for forming said packet and sending back said packet to said authentication end;
step six:
performing said operation by said authentication end for reading data of fingerprint minutia from an authentication device so as to compare a fingerprint minutia;
and
step seven:
granting said user to access network resources if said user passes the authentication and replying the authentication result.
