Description

A kind of security certification system based on the acquisition of virtual implementing helmet brain line
Technical field
The present invention relates to safety certification field, in particular to a kind of safety certification based on the acquisition of virtual implementing helmet brain line System.
Background technique
Brain wave (ElectroEncephaloGram, EEG) is a kind of nonlinear random signal, with the period, amplitude and Phase is to place exploring electrode in the head surface of people, between the paired electrode of record as the Fundamentals for constituting its waveform Potential difference variation.Confirm that at least there are four different brain waves in brain: " α " (Alpha) by the research of neuroscientist Brain wave, frequency 8-12Hz, " β " (beta) brain wave, frequency are 14-100Hz, " θ " (Xi Ta) brain wave, frequency Rate 4-8Hz, " δ " (Delta) brain wave, frequency 0.5-4Hz.The activity (activity) of brain wave refer to EEG wave or Continuous (such as β activity, α activity etc.) of person's wave;The rhythm and pace of moving things (rhythm) of brain wave refers to the wave institute structure by the constant period At 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, and is had characteristic Waveform or occur fairly constant waveform repeatedly, with background activity distinguishing 2 or 2 or more wave Xiang Lianxu (such as The slow complex wave of spine, point slow complex wave, K complex wave etc.).
Brain line is the feature of the eeg signal measured, and the brain of different people has a certain specific matters different anti- It answers, 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 object.Brain wave be to the reaction of specific matters it is unique, everyone is not quite similar, it by scientist letter Referred to as " brain line ".If this reaction verified as unique password, cipher round results are very difficult to crack.
Current security certification system mainly uses numerical ciphers certification, picture password certification or living things feature recognition to recognize Card.Wherein, biological feather recognition method has: fingerprint recognition, recognition of face, iris recognition, voice recognition, hand identification, palmmprint Identification, signature recognition, Gait Recognition etc..
In various biological feather recognition methods, fingerprint recognition is most widely used.Fingerprint refers to the positive surface skin fovea superior of finger The lines of convex injustice.Although fingerprint is the sub-fraction of human skin, it has contained a large amount of information.These fingers The lines of skin be on pattern, breakpoint and crosspoint it is different, they are referred to as " special by we in information processing Sign ", these features are different each finger.Moreover, the fingerprint characteristic of people be it is inherent, birth 6 months after It basically forms, hereafter, significant change just no longer occurs for the streakline type of fingerprint, structure, overall distribution of statistical nature etc..According to By fingerprint characteristic uniqueness feature, we can be mapped a people with his fingerprint, special by comparing his fingerprint It seeks peace the fingerprint characteristic pre-saved, so that it may verify his true identity.
Compared to fingerprint, brain line has a variety of behavioral characteristics.Brain line may be used as identification terrorist or other danger point The method of son, by measuring him when specific written document known before showing to him or image (such as training camp or handbook) " brain line ".Brain line can be also used for identification, as fingerprint, iris, can be applied to numerous safety certification occasions.
In terms of identifying personal identification, brain line has the no potential advantages of some fingerprints.For example, if someone fingerprint It is stolen, the leeway that he does not just retrieve substantially, because fingerprint is " irrevocable ".Fingerprint exists as safety certification to be usurped With the possibility of failure.When finger is peeled because of reasons such as dry weathers, cause identification abnormal.After fingerprint is by stamp, it is easy quilt Abuse.As soon as the event leaked more than 6,000,000 user fingerprints once occurs to the tight famous U.S. in safety measure.And brain Line is then different, it can be cancelled.In case of extremely individual situations, 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 identify " cognitive characteristics " of a people, the state of mind of rapid evaluation visitor.To sentence The cognitive state of disconnected visitor, can whether the state of mind be normal, allow visitor to enter system.For example, an if aerial friendship Logical controller is too tired or attention is more dispersed, even if his authentication success, he also cannot be introduced into system.If The state of mind is good before one pilot enters system, occurs abnormal, the then brain line acquisition in aircrew helmet in flight course After device monitoring to abnormal brain line, it can send a warning message to earth station, to adopt remedial measures.
Although brain line is with having many advantages in terms of safety certification, there is no a kind of peaces based on the acquisition of brain line at present Full Verification System and method.
