Identity checking system by light blinking id-beacon using image sensor

Abstract

In this paper, a new method for the ID checking system was proposed by using the Visible Light Communication (VLC). The proposed method uses an image sensor of webcam camera and smartphone that can use fulfill some limitations of QRCode and RFID technology. In the experiment, ID the system can identify identity codes transmitted in 1-50 meters in daytime and night to find the processing time for the first time to detect LED Blinking. As the result, the performance of ID checking can use webcam camera to identify objects the maximum distance in daytime and night but smartphone can identify in short distance at night. Comparing a performance for application in various systems between webcam camera and smartphone image sensor.
