Invisible Information Casting System Based on Visible Light Communication
An invisible information casting system based on visible light communication (VLC) is proposed.Invisible information is embedded in normal displayed images which can be captured by imaging devices and recovered by corresponding decoding algorithms under the premise of displaying original images and videos normally.Transmitting advertisement information in the invisible way can avoid the harassment by mass media and realize directional advertisement to the target customers.The system is easy to be transplanted to many handheld devices like cell phones and pads.Finally,the system feasibility is verified and the main factors which affect the system performance are evaluated through experiments.
