Robust Index Code with Digital Images on the Internet

Abstract

A new color code which has high robustness is proposed, called Robust Index Code (RIC for short). RIC can be used on digital images and link them with the database. There are several technologies embedding data into images such as QR Code and Digital watermark. QR Code cannot be used on digital images because it does not have robustness on digital images. Besides Digital watermark can be used on digital images, but embedded data cannot be extracted 100% on damaged images. From evaluation using our implemented RIC encoder and decoder, the encoded indexes can be extracted 100% on compressed images to 30%. We also implemented a doubt color correction algorithm for damaged images. In conclusion, RIC has the high robustness on digital images. Hence, 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.

Robust Index Code to Distribute Digital Images and Digital Contents Together

“…In Fig. 2 Example of RIC circle [9] addition, unlimited data can be linked with digital images because of using a database index. For now, RIC embeds only 50-bit index into each digital image, assuming a server on the Internet to store its content data.…”

“…Because the border prevents the degradation into the square, the shape of square will remain as same as the original square like shown in Fig. 5 Decoding process [9] Fig. 4.…”

“…Superdistribution system [10] is an ideal proposal to distribute digital products in which software is made available freely and without restriction but is protected from modi-Fig. 9 New superdistribution system architecture [9] fications and modes of usage not authorized by its vendor, and normally there are three principal functions [42] :…”

“…In this paper, revised Robust Index Code (called RIC) of our previous paper in SIGMAP 2016 [9], a brand new color codemark targeting digital images on the Internet is developed. This technique provides extremely high robustness on JPEG Compression and Resize which makes it possible to guarantee to extract 100% original embedded data on the sharing images on the Internet.…”

“…The result shows that the data of RIC are extracted Fig. 1 RIC Concept: RIC embeds a database index, and the database stores various data types [9]. 100% on the images, damaged by multiple times of over 420 pixels Resize and 30% JPEG Compression at the same time.…”
