“…Digital media content distribution has achieved rapid growth recently [1]. The contents are distributed in various ways, such as 2D Barcodes [2], Watermark [3], Digital Rights Management (DRM) [1], [4] and so on. However, the platform-independent distribution system being able to share digital contents on the Internet with high robustness is not realized.…”

“…However, the platform-independent distribution system being able to share digital contents on the Internet with high robustness is not realized. In [2], the contents are distributed by device-todevice transmission, so that it is not an appropriate method for sharing them. In [3], Reversible Data Hiding (RDH) using the watermark scheme is proposed but the embedded data get damaged on JPEG Compression.…”

The main purpose of Codemark is to distribute digital contents using offline media. Due to the main purpose of Codemark, Codemark cannot be used on digital images. It has high robustness on only printed images. This paper presents a new color code called Robust Index Code (RIC for short), which has high robustness on JPEG Compression and Resize targeting digital images. RIC embeds a remote database index to digital images so that users can reach to any digital contents. Experimental results, using our implemented RIC encoder and decoder, have shown high robustness on JPEG Comp. and Resize of the proposed codemark. The embedded database indexes can be extracted 100% on compressed images to 30%. In conclusion, it is able to store all the type of digital products by embedding indexes into digital images to access database, which means it makes a Superdistribution system with digital images realized. Therefore RIC has the potential for new Internet image services, since all the images encoded by RIC are possible to access original products anywhere.

“…This type of distortions severely affects the performance of Quadrature Phase Shift Keying (QPSK) -Orthogonal Frequency Division Multiplexing (OFDM) modulation. To avoid this, DPSK-OFDM modulation is used [9]. Here data is stored in phase difference of adjacent frequency components.…”

QR codes have played a significant role in mobile applications due to their beneficial properties, including small tag, large data capacity, reliability, and high-speed scanning. Any information on a cell phone can be transmitted to a second cell phone as QR code displayed on the LCD which is then captured using camera of second phone and can be decoded there. But motion-blur distortions can be introduced in captured image due to relative movements during capture. This can be solved by using orthogonal frequency division multiplexing (OFDM) modulation along with differential phase shift keying (DPSK). In this technique, large number of closely spaced orthogonal sub-carriers carries data on several parallel data streams (channels). The sub-carriers can be modulated with any of the conventional modulation techniques whereas here DPSK modulation is used. In order to make the subcarriers orthogonal, Inverse Fast Fourier Transform (IFFT) is applied. This modulated message is encoded into QR code is displayed. The original message can be obtained by applying Fast Fourier Transform (FFT) on QR code captured by receiver, followed by demodulation. Since data is stored in phase difference, adjacent elements are less affected by the motion blur distortions. However, the private data of the QR barcode lacks adequate security protection. Due to the visual nature, 2D barcodes are subject to eavesdropping when they are displayed on the Smartphone screens. In order to add security to this data transmission, AES 128 encryption is used.
