The invention discloses an identity identification method based on a quick voice presentation normal form of an electroencephalogram. The identity identification method which is put forward by the invention can overcome the defects that an authentication certificate is likely to be forgotten and stolen or lost by aiming at certain traditional identity identification and individual certification methods, including passwords, PINs (Personal Identification Number), radio frequency cards and the like; meanwhile, a vision disorder population is considered and can not be realized by electroencephalogram visual certification, so that the method which is put forward by the invention is suitable for the population with visual disturbance; electroencephalogram data obtained after a subject receivesvoice stimulation is collected to obtain an initial electroencephalogram dataset D, and the dataset D can not be directly subjected to feature extraction but is firstly subjected to denoising (low-pass filtering, coherent average and quick independent component analysis) to obtain a preprocessed dataset D'; then, carrying out feature extraction on the dataset D' to obtain a training feature set C;and finally, carrying out classified identification to carry out identity authentication.
