The CSK receiver and transmitter can identify a specific SDM frame shape, chromaticity coordinate assignment area in a color diagram, and the CSK code. After identifying both the chromaticity coordinates of CSK cells and the
frame shape, the corresponding CSK cell content is paraphrased into the original data by different mapping tables. To introduce CSK communications for commercial purposes, security must be enhanced by adopting encryption technologies. It should also be noted that changing the shape of the CSK frame can significantly improve security and the error-free performance can be attained by increasing the number of CSK symbols in a frame. We also describe new communication service concepts that can be implemented with the current technological level of CSK communication. We propose smart glasses applications using cyberphysical space by combining the VLC technology and a computer database, leading AR applications
