Brain activity-based biometric authentication with a password

A computer readable storage medium embodying computer program code, the computer program code comprising computer executable instructions configured for authenticating information of a user by:

• generating a user prompt identifying a mental task to be performed by the user;
• sending the user prompt to a computing device for presentation to the user;
• receiving a biometric brain activity signal that is collected by scanning the user during a scanning interval when the user performs the mental task, where the biometric brain activity signal reflects brainwave activity of the user when performing the mental task;
• comparing the biometric brain activity signal to a reference biometric template signal;
• and
• determining whether to authenticate the user based on whether the biometric brain activity signal matches the reference biometric template signal.
