A system for a new two-dimensional code: secure 2D code

摘要

A new 2D code called Secure 2D code is de- signed in this paper, both encoder and decoder are also pro- posed. Secure 2D code can store any kind of data and pro- vides high security. With regard to security, the input data is divided into two parts: general and secret. The general data is transformed into a 2D code pattern, then secret data is hidden in the 2D code pattern. To raise the reading speed and allow various reading environments, some features are added around the 2D code pattern boundary. As to the reli- ability, RS code is adopted to treat damaged patterns.
