Abstract: This is a proposal for Invisible-Watermarking Image Sensor Communication (IISC) Scheme
based on the Intensity Modulation technique of a image pixel. The proposed scheme is asynchronous and
supportive for frame rate variation. This scheme is feasible for different kind of digital signage application,
smart advertising, device-to-device communication and so on.
Purpose: Call for Proposal Response

Invisible-Watermarking Image Sensor Communication (IISC): Communication
between any image senor such as camera and imaging device, for instance, display,
monitor, digital signage etc. can be defined as IISC.

Working Principle
Image Frame
Steps:
1. During video transmission, one image frame is
made as reference image and the sequential image
frame is modulated to transmit data i.e. the frame
#i is the reference frame and the #(i+1) is the data
frame.
2. The image is divided into NxM block where each
block contains group of pixel. If the image frame
contains PxQ pixel (P=row of pixel, Q= column of
pixel), then every block will contain approximately
(PxQ)/(NxM)= R pixels.
3. The data can be embedded real-time or prior to
data transmission.
4. The data bit ‘1’ interprets changing in the average
intensity or less intensity elements of the pixel
block; while the ‘0’ indicates no variation in the
intensity of the pixels in the block.
5. The reference image and the data image is
compared to extract the data.
