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.
