ABSTRACT:
A method and apparatus for authenticating subscriber units (30) and users (25) in a communications system includes a communications node (200) which receives biometric information describing a user (25), and measures an RF signature of the subscriber unit (30). The biometric information and RF signature are compared against a valid user profile to determine authenticity of the user (25) and the subscriber unit (30). The biometric information can include retinal scan data, fingerprint data, or other data. The RF signature can include spectral content, phase or frequency characteristics, or other identifying features.
