Real-time security authentication method based on EEG data features

Abstract

The invention discloses a real-time security authentication method based on EEG data features, and belongs to the technical field of brain waves. A personal safety certification library is constructed, a certification terminal sends a safety certification request to a safety certification server based on an instruction, the safety certification server sends at least one vibration frequency based on the instruction, a user holds the terminal to acquire the vibration frequency, vibration is sent based on the frequency, and at least one brain wave signal generated by the user under vibration stimulation is obtained; data are encrypted and transmitted to a security authentication server for feature extraction and analysis, comparison is performed based on features of at least one brain wave signal generated under vibration for authentication, and an instruction is sent to the authentication terminal based on a comparison result; vibration is adopted as a stimulation source, so that the influence of emotion on a result is avoided, and the verification accuracy is improved; and meanwhile, based on frequency mapping, a random verification password can be generated in real time during each security authentication, and then a corresponding vibration frequency is generated based on the verification password, so that real-time authentication is realized.

Description

technical field [0001] The invention belongs to the field of brain wave technology, in particular to a real-time security authentication method based on EEG data features. Background technique [0002] Electroencephalogram (Electroencephalogram, EEG) is a method that uses electrophysiological indicators to record brain activity. When the brain is active, the synchronous post-synaptic potentials of a large number of neurons are summed and formed. Everyone's brain waves are different, so with the development of science and technology, researchers gradually apply brain wave technology to security authentication, perception and other technical fields; such as CN201510813543. The most important is to use the image verification information as a stimulus source, so that when the user observes the image, he will induce corresponding emotional fluctuations, radiate brain waves, collect this part of the brain waves for verification, and judge whether he is an authenticated user; emot...

Problems solved by technology

[0003] Based on the above description, it can be known that the existing technology assumes that when a person is emotionally stable, the same person's brain responds almost the same to the same picture or the same piece of audio and video; but if the mood fluctuates, the brain wave It is impossible to ensure whether the correspondence can be obtained, which will lead to the deviation of the existing scheme. At the same time, based on the brain wave classification of emotional fluctuations, it can be known from the existing literature that the selection of the transition-dependent algorithm is very different; and the existing research It is found that human emotions include six basic emotions of happiness, sadness, anger, surprise, fear and disgust, and also include admiration, worship, appreciation, entertainment, anxiety, awe, embarrassment, boredom, calmness, confusion, desire, disgust, empathy Pain, fascination, jealousy, excitement, fear, hate, fun, joy, nostalgia, romance, sadness, satisfaction, sexuality, sympathy and gratification 27 different extended emotions, and each emotion can coexist; The emotions derived from observing the same audio and video data in different age groups may be different, such as being happy when young and calm when middle-aged; therefore, it can be judged that it is not appropriate to use emotions as a means of security certification; therefore, the applicant proposes a The new technical means solves the authentication method that relies on emotion as the core in the existing technology, and at the same time realizes the random authentication method through the new technical means to ensure the security and real-time performance of the authentication
