The present invention provides a biological identification feature based access control method and system. The method comprises: receiving a biological identification feature of a human body, and sending the biological identification feature of the human body to an intelligent card to perform biological feature verification; receiving a biological feature verification result sent by the intelligent card; and if the biological feature verification is passed, granting corresponding access control permission. Since the received biological identification feature is sent to the intelligent card to perform biological feature verification, the biological identification feature does not need to be stored in an authentication end or transmitted in a system network, and security of the biological identification feature of a user can be ensured to a certain degree.
