Abstract
The invention relates to a one-time password generating method and an apparatus. The method includes steps of collecting fingerprint images, extracting fingerprint feature data from those fingerprint images, and comparing the fingerprint feature data with one or more pre-stored fingerprint feature templates for authentication. After the authentication is passed, a one-time password is generated by the corresponding fingerprint feature template or a user's secret corresponding to the template. The invention also discloses a one-time password apparatus, including a fingerprint collecting unit, a fingerprint feature extracting unit, a storage unit, a comparison unit, a one-time password generating unit, a control unit, and an output unit. By adding fingerprint authentication function to a one-time password generating apparatus, the invention avoids disadvantages such as no user authentication in the present apparatus, only for a single user, and imitation of the apparatus by others when it is lost or theft, as a result, increases security of the apparatus.
