The invention provides an anti-fake iris identity authentication method used for intelligent glasses. According to the method, requirements for periphery devices are low, multiple faking methods can be detected, and the high-adaptability anti-fake purpose is achieved. The method comprises the steps of (1) extracting standard images and saving user iris characteristics in the standard images as standard iris characteristics; (2) generating a random incident light intensity change sequence based on ambient light to stimulate the eyes of a user, collecting a dynamic user eye image, obtaining an eye image sequence, and extracting and saving user iris characteristics in the dynamic eye image as iris characteristics to be detected; (3) obtaining a pupil diameter change sequence through the dynamic user eye image and calculating the matching rate Pass1 between the pupil diameter change sequence and the incident light intensity change sequence; (4) selecting an image to be authenticated from the dynamic user eye image, selecting a comparison standard image from the standard images, and calculating the matching rate Pass2 of the iris characteristics of the image to be authenticated and the iris characteristics of the comparison standard image; (5) obtaining an authentication result according to the Pass1 and the Pass2.
