Abstract:
In this demo, we present UnseenCode, an invisible on-screen barcode scheme. We borrow inter-frame embedment method from VLC-based screen-camera communication techniques to achieve invisibility. Unlike existing VLC-based methods, UnseenCode does not require video-based extraction which is more unreliable and computationally expensive on off-the-shelf smartphones when compared to image-based extraction of traditional barcode methods. We design a delicate image-based barcode extraction method based on cross-component correlation of color images. Our demo implementation includes a transmitter running on desktop computers, and a scanner application running on any off-the-shelf Android smartphones. We would like to exhibit the applicability of UnseenCode in the real world.
