Abstract: The present invention discloses a method and system for authentication that is coercion resistant by using music that invokes reproducible neurological responses uniquely to a user in order to authenticate the user. The neurological responses may include neurochemical activities inside the brain and brain waves. The unique neurological response of a user to his or her selected music is stimulated by neurochemical release such as dopamine. During the most pleasing part of the music, the user's neurochemical activities and brain waves notably change, which can be captured by using sensors. The timing, rate and extent of the notable change in neurological responses can be used to form a user's unique and non-transferable password. The present invention can be used to authenticate a user while preventing against standard attacks as well as coercion attack, i.e., forcing the user to provide his or her authentication material such as a password.
