Abstract

The invention relates to a safety management system for storing digital teaching materials, which includes a reserve unit, an authority unit, a collection unit and a central control unit. The present invention classifies the teaching material data by setting the reserve unit and acquires the authority of the important teaching material data, which improves the safety of important teaching materials and also improves the wide use of common teaching materials. When the acquirer needs to acquire important teaching materials At the same time, the acquisition unit is set to collect multiple groups of face images, which improves the accuracy of the face images. At the same time, the acquired face images are corrected by setting the central control unit, and the acquisition distance is compared by the image definition and the facial image ratio. Correction, the image offset is corrected by the level difference of the two eye images, and the acquisition angle is corrected by the facial area and brightness difference on both sides of the face image, which improves the accuracy of the acquired image and improves the face recognition. efficiency.

Description

technical field [0001] The invention relates to the technical field of face recognition security, in particular to a security management system for digital textbook storage. Background technique [0002] Digital textbooks, that is, digital textbooks, are different from traditional textbooks. They use multimedia technology to digitize traditional paper content and transform them into interactive textbooks suitable for various electronic terminals. Due to the high degree of openness of digital textbooks, important textbooks When storing data and test paper data, considering the security of important data, it is often necessary to use encryption processing. Face recognition is a more effective encryption method. [0003] In the face processing method in the prior art, since the collected real-time face images cannot be fully corrected, the angle and environment of the person to be photographed are required to be high, and there will also be problems requiring multiple acquisiti...
