Description

A kind of security certification system gathered based on virtual implementing helmet brain line
Technical field
The present invention relates to safety certification field, more particularly to a kind of safety certification gathered based on virtual implementing helmet brain line System.
Background technology
Brain wave (ElectroEncephaloGram, EEG) is a kind of nonlinear random signal, with the cycle, amplitude and Phase place, as the Fundamentals for constituting its waveform, is the head surface placement exploring electrode in people, between the paired electrode of record Potential difference changes.Through the research confirmation of neuroscientist, at least four different brain waves in brain:" α " (Alpha) Brain wave, its frequency is 8-12Hz, " β " (beta) brain wave, and its frequency is 14 100Hz, " θ " (Xi Ta) brain wave, its frequency Rate 4-8Hz, " δ " (Delta) brain wave, its frequency are 0.5-4Hz.The activity (activity) of brain wave refer to the ripple of EEG or Continuous (such as β activities, α activities etc.) of person's ripple;The rhythm and pace of moving things (rhythm) of brain wave is referred to by the ripple institute structure in constant cycle Into electrical activity of brain (such as beta response, alpha rhythm, spine rhythm and pace of moving things etc.);Complex wave (complex) is then defined as, with distinctive Waveform or there is repeatedly fairly constant waveform, the ripple of distinguishing with background activity 2 or more than 2 mutually continuous (for example The slow complex wave of spine, point slow complex wave, K complex waves etc.).
Brain line is the feature of the eeg signal for measuring, and the brain of different people has different anti-to a certain specific matters Should, so as to produce the brain wave of different characteristic, by the external manifestation feature of brain wave, can be used as particular person or specific thing The basis of characterization of thing.Brain wave is unique to the reaction of specific matters, and everyone is not quite similar, and it is by scientist's letter Referred to as " brain line ".If this reaction being verified as unique password, its cipher round results is very difficult to crack.
Current security certification system is mainly recognized using numerical ciphers certification, picture password certification or living things feature recognition Card.Wherein, biological feather recognition method has:Fingerprint recognition, recognition of face, iris recognition, voice recognition, hand identification, palmmprint Identification, signature identification, Gait Recognition etc..

Compared to fingerprint, brain line has multiple behavioral characteristics.Brain line can serve as recognizing terrorist or other danger point The method of son, by showing to him before familiar specific written document or measure him during image (such as training camp or handbook) " brain line ".Brain line can be also used for identification, as fingerprint, iris, can be applicable to numerous safety certification occasions.
In terms of identification personal identification, brain line possesses the potential advantages that some fingerprints do not have.For example, if someone fingerprint Stolen, the leeway that he does not just retrieve substantially, because fingerprint is " irrevocable ".Fingerprint is used as safety certification presence and usurps Possibility with failure.When finger is peeled because of reasons such as dry weathers, cause identification abnormal.After fingerprint is by die, easy quilt Abuse.As soon as once there is the event more than the leakage of 6,000,000 user fingerprints in safety measure to the tightly famous U.S..And brain Line is then different, and it can cancel.In the event of extremely individual other situation, hacker really tries to steal from authorized user there " brain line ", authorized user can also reset " brain line ".
Brain line can also be used to " cognitive characteristics " for recognizing a people, the state of mind of rapid evaluation visitor.So as to sentence Can whether the cognitive state of disconnected visitor, the state of mind be normal, allow visitor to enter system.For example, if an aerial friendship Logical controller is too tired, or notice, than relatively decentralized, even if his authentication success, he also cannot be introduced into system.If Before one pilot's entrance system, the state of mind is good, occurs abnormal, the then brain line collection in aircrew helmet in flight course To after abnormal brain line, can send a warning message device monitoring earth station, to adopt remedial measures.
