Abstract: Visible light communication (VLC) is relatively secure communication when it compared with other wireless communications using radio frequency (RF). Visible light communication systems provide another to the current standards of wireless transfer of information, It is done by using light from LEDs it act as a communication medium for illumination as well as low cost, high speed, high power efficence and secure data communication. It can use as underwater light because LED operate at lower temperatures, use less energy, better vibration, work with DC voltages, and last far longer than conventional incandescent bulbs. Here a light encryption scheme using devices having light-emitting diode (LED) and a camera image sensor which is used under water. The original visible signal sending from the lamp can be first received by the proposed light encrypter, The information is encrypted and then emitted. In optical domain the light encrypter act as an encryption gateway for the signals. The rolling shutter effect of the complementary metaloxide semiconductor (CMOS) camera can be used, the data information can be obtained by demodulating the rolling shutter pattern. To define the data logic in the rolling shutter pattern we use Otsu thresholding scheme.
