Proposal of Secure Business Architecture by Visible Light Communication System

Progress in visible light technology has provided increased opportunities for new mobile communication infrastructure and business creation using visible light communication. This paper proposes a secure business architecture through collaboration of technologies in visible light communication, public key cryptography, and power line communication. Moreover, it presents an evaluation on the technology's effectiveness using a concrete business architecture. This model using visible light communication gives an "optical attestation ID" to the source of LED light, and it is characterized by strict position authentication that enciphers these data using public key infrastructure (PKI). Furthermore, the network between the server for distributing the optical authentication ID and the LED light source enables high security using power line communication. Thus, we achieved a secure business architecture using visible light communication, one that can contribute to the creation of new business such as optical electronic value trading platforms, optical digital signage, and optical Fintech.
