A trading system for bidding multimedia contents on mobile devices

초록

Recently, new interests on digital contents and UCC(User Created Content)s are growing fast through the heterogeneous interest environment. However, there have been many side-effects on those interests. The representative problems are perverting illegal copies and the distributions for personal valuable digital contents to unauthorized anonymous users. These decrease creation motivation of good contents by interfering with the growth of information technology industry and the content provider's creative will. To resolve these problems, in the paper, we propose a novel auction system for multimedia contents and bidding processes. We call the system as MobileAuction. The system first regards the digital contents as the physical materials, and applies the concept of used goods onto digital contents. Especially, the auction system is based on mobile environment. We present new model of the auction process on digital contents by analyzing major algorithms among main auction processes. Finally, the performance evaluation shows that the main auction process algorithms indicate the time complexity of logarithm scale for insertions and searches even though we don't focus on the performance of the presented system. Therefore, the performance of the system is not significantly influenced by the amount of contents even though the volume of contents in the system is increasing. Our main idea of the paper proposes a novel multimedia content auction system. © 2011 Springer-Verlag.
