This paper proposes a protocol, called BIO3G, for embedding biometrics in 3G security. BIO3G is an enhanced alternative to the common practice of utilizing biometrics locally, for gaining access to the device. BIO3G provides real end-to-end strong user authentication to the mobile operator, requiring no storing or transferring of biometric data and eliminating the need for biometric enrolment and administration procedures, which are time-consuming for the user and expensive for the mobile operator.
