A new method of QR code accumulation encoding in mobile education

QR code identification is a kind of effective method in mobile education information authentication, this paper puts forward a new QR code accumulation encoding method owing to the limited information faults in traditional QR code encoding. The accumulation of segmentation and bar code decoding identification were improved in this method. Through experiment analysis and compared with the original QR code encoding, it can be concluded that the method in encoding output, image segmentation and decoding aspects has better effects for large capacity files.

I. Introduction

Mobile education refers to the movement of the study area or the use of mobile learning tools implement education, the corresponding user group also has mobility. Under this environment in order to safeguard the rights and interests of the users, to identify users legal information is indispensable link. Two dimensional barcode identification authentications is a common way, it has a series of superiority such as high information capacity, high reliability, and supports multiple error correction level. It is a concise and cheap way of information storage. In specific encoding rules, the two-dimensional bar code technology can compress numbers, text and image data sources into geometry image. Decoding device in reading this graphics can restore this graphics into the corresponding original data according to the appropriate decoding algorithm.
