This paper considers improving the confidentiality of the next generation of wireless communications by using the watermark-based blind physical layer security (WBPLSec) in Visible Light Communications (VLCs). Since the growth of wireless applications and service, the demand for a secure and fast data transfer connection requires new technology solutions capable to ensure the best countermeasure against security attacks. VLC is one of the most promising new wireless communication technology, due to the possibility of using environmental artificial lights as data transfer channel in free-space. On the other hand, VLCs are even inherently susceptible to eavesdropping attacks. This work proposes an innovative scheme in which red, green, blue (RGB) light-emitting-diodes (LEDs) and three color-tuned photo-diodes (PDs) are used to secure a VLC by using a jamming receiver in conjunction with the spread spectrum watermarking technique. To the best of the author's knowledge, this is the first work that deals with physical layer security on VLC by using RGB LEDs.
