Atomic word secure digital (SD) learning card management system

Abstract

The invention discloses an atomic word secure digital (SD) learning card management system which consists of a management control system, a central database system, an SD card management system, an equipment serial number (SN) management program, a HASH management program, a verification module, a user management module, an order management module and a client management system, wherein the SD card management system comprises a card-issuing module, an encryption and decryption module, a card operation module and a content protection for recordable media (CPRM) management system; the client management system comprises the verification module, an input / output module, an encryption and decryption module, a card operation module, a CPRM management system, the equipment SN management program, the HASH management program, a user management interface and an order management interface; and the client management system is relatively independent, is independently arranged on a client, is used for verifying, controlling and managing, and has communication with the central database system by an SD card operation module.

Description

technical field [0001] The invention relates to the field of making SD learning cards, in particular to the field of designing SD learning cards based on an atomic word learning method and capable of communicating with a multifunctional card-type point-touch learning machine. Background technique [0002] Electronic learning machines have been widely used in various teaching and teaching aids, and are currently a popular learning tool. However, since the current electronic learning machines are generally in an electronic state, the update of their learning resources is more complicated, or even impossible, and they have become disposable school supplies without compromise, which is not conducive to the repeated use of resources. [0003] With the continuous development of social science and technology, there are also learning machines based on operating systems such as Android, which solve the problem of updating learning resources to a certain extent, but because their upda...

Problems solved by technology

Although the former saves costs, most of its learning courses are updated for free, so developers are not very motivated. Although the latter takes care of the enthusiasm of course developers, it needs to replace the entire learning machine in the face of new courses. , the cost paid by learners is extremely high

[0010] In response to this, there are currently some learning machines that are updated and sold in the form of learning cards, but due to the small capacity of learning cards or poor confidentiality, it is not conducive to large-scale promotion
