Abstract
A user recognition system that utilizes two CCD cameras to obtain two images of the user from two different angles of view. A three-dimensional model of the user'"'"'s face is created from the obtained images in addition. The generated model and an additional facial texture image of the user are compared with a stored user profile. When the obtained 3D model and facial texture information matches the stored profile of the user, access is granted to the system.

13. A mobile terminal for recognizing a user'"'"'s identity when they are attempting to access a system, comprising:
-
at least one charged coupled device (CCD) camera adapted to obtain at least two still images of the user'"'"'s face from at least two different predetermined angles of view and to obtain at least one still image of the user'"'"'s face;
memory means for storing user profile information relating to authorized users of a system; and
processing means connected to said at least one CCD camera and said light source for generating a 3-dimensional model of the user'"'"'s face using the at least two still images, and for generating a facial texture but map of the user'"'"'s face using the at least one still image, said processing means comparing the 3-dimensional model and the facial texture bit map to the stored user profile information contained in said memory means and enabling access to the system when the generated 3-dimensional model and facial texture bit map match a user profile stored in said memory means. - View Dependent Claims (14, 15, 16)

17. A method for recognizing a user using a mobile hand held terminal during an attempt to access the mobile terminal, comprising the steps of:
-
obtaining, by the mobile terminal, at least two 2-dimensional still images of the user from at least two different angles of view;
sending the images to a server over a network;
generating, by the server, a 3 dimensional model of the user'"'"'s face from the obtained images;
determining, by the server, the user'"'"'s facial shape using the generated 3-dimensional model;
sending the 3-dimensional model and the user'"'"'s facial shape to the mobile terminal;
comparing, at the mobile terminal, the determined facial shape with profile information stored in memory, the profile information comprising data relating to the facial shape of authorized users; and
determining, at the mobile terminal whether the determined facial shape matches the profile information stored in the memory. - View Dependent Claims (18)
