Security certification system based on virtual reality helmet brain grain collection

Abstract

The invention discloses a security certification system and method based on virtual reality helmet brain grain collection. The system comprises a data access module, a brain grain generation module and a security certification module, wherein the data access module generates a first brain grain feature parameter corresponding to identity information of a user according to a preset brain grain local database; the brain grain generation module acquires a second brain grain feature parameter generated under stimulation to the user based on audio and video signals; the security certification module compares the first brain grain feature parameter with the second brain grain feature parameter, and carries out recognition and security certification on the identity of the user according to a comparison result. The security certification system solves the problem that no brain grain collection-based security certification system is provided at the present in the prior art, and has the advantage that a brain grain password is not liable to steal, copy and abuse; under an extreme condition, if the brain grain password is leaked, the user can reset the brain grain password conveniently.

Description

technical field [0001] The invention relates to the field of security authentication, in particular to a security authentication system based on virtual reality helmet brainprint collection. Background technique [0002] Electroencephalogram (ElectroEncephaloGram, EEG) is a nonlinear random signal, with period, amplitude and phase as the basic factors of its waveform. Variety. Research by neuroscientists has confirmed that there are at least four different brain waves in the brain: "α" (Alpha) brain waves, whose frequency is 8-12Hz, "β" (Beta) brain waves, whose frequency is 14-100Hz, "θ" (theta) brain waves have a frequency of 4-8 Hz, and "δ" (delta) brain waves have a frequency of 0.5-4 Hz. Brain wave activity (activity) refers to the EEG wave or wave continuity (such as β activity, α activity, etc.); brain wave rhythm (rhythm) refers to the brain electrical activity (such as β Rhythm, alpha rhythm, spine rhythm, etc.); complex (complex) is defined as a characteristic w...
