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.
