In this study, we propose color barcodes using tree-structure joint stereo coding (TJSC). TJSC is a method that combines sets of tree-structure coding channels. Optimum pairs of reference channels are searched by using vector similarity to form channel pairs. TJSC is expected to improve the compression ratio by 6% on average when compared to the conventional joint stereo coding methods. In this study, we propose high capacity color barcodes with bit data arranged in multilayers that provide color information to each layer. As both tree-structural and coding information are generated during coding by TJSC, encrypted color barcodes can be generated by generating a decoding key of the tree-structural information. The color barcodes proposed in this study are expected to be accepted as a new printing medium that employs an information protecting function and uses an electronic medium with a high security function.
