Data Hiding Based on Mini Program Code

A mini program code (also known as sunflower code) comes with WeChat APPs. With the popularization of APPs, codes have become more and widely used. As a new carrier, study information hiding technology based on is great significance for expansion covert communication carriers can also deal security problems in advance. At present, to best our knowledge, there no steganographic research codes. In this paper, we propose scheme embed secret into first time. After studying construction codes, coordinate system constructed represent its module coordinates. Then, binary stream message embedded encoding region or edge patch. Experiments show that proposed data effective feasible. The could be extracted while keeping readability code. Moreover, payloads patch V-36 are 72 bits 29 bits, respectively.
