Method and system for authenticating passwords on basis of brain wave signals

Abstract

The invention discloses a method and a system for authenticating passwords on the basis of brain wave signals, and relates to the technical field of security authentication. The method includes allowing a user to select an initial brain password according to requirements, extracting feature information of the initial brain password to form an authentication brain password, transmitting the authentication brain password to terminal equipment where security authentication is required and completely registering application of the terminal equipment; allowing the user to transmit an authentication brain password to the terminal equipment when security authentication is carried out on the application of the terminal equipment, enabling the terminal equipment to compare the authentication brain password transmitted by the user to the authentication brain password transmitted when the user is registered, checking whether the authentication brain passwords are matched with each other or not, determining that the user passes authentication if the authentication brain passwords are matched with each other, or determining that the user fails to pass authentication if the authentication brain passwords are not matched with each other. The method and the system have the advantages that the 'brain passwords' are technically used for recognizing and authenticating identities, particularly, the personal brain wave signals are difficult to counterfeit or copy, and accordingly the safety of security authentication can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of security authentication, in particular to a method and system for password verification based on brain wave information in the field of brain-computer interface. Background technique [0002] Brain-computer interface (brain-computer interface, BCI), sometimes referred to as "brain port" direct neural interface or "brain-computer fusion perception" brain-machine interface, it is in the human or animal brain (or brain cell culture) A direct connection path established with an external device. In the case of a one-way BCI, the computer either accepts commands from the brain or sends signals to the brain (such as video reconstruction), but cannot send and receive signals at the same time. The two-way brain-computer interface allows two-way information exchange between the brain and external devices. In this definition, the term "brain" means the brain or nervous system of an organic life form, not j...

Problems solved by technology

If a common password is used, there must be potential security risks, and the use of independent passwords puts forward high requirements on the user's memory, which is easy to cause password forgetting
