Model analysis of digital copyright piracy on P2P networks

Distribution of copyrighted material through the Internet, while considered by some as a possible business opportunity, has been infested with piracy in reality. Infringement of copyright law on peer-to-peer networks has been expanding rapidly according to S. Sen and J. Wang (2002) and S. Saroiu et al. (2002) making it nearly impossible to get an accurate estimate of the amount of pirated materials that are being transmitted. The current Japanese Diet amended the compensation law, making it possible to calculate compensation based on the quantity of illegally transmitted material (received duplication). However, the means in which to determine the exact quantity is yet to be determined. What is the amount of illegally copied material necessary to dent production incentives? What is the price society has to pay to minimize the spread of illegally copied works? These questions need to be answered to come up with a plausible policy regarding pirated works. Based on the context presented above, the analysis presented in this paper focus on determining the reality of digital copyright infringement, as well as creating and analyzing a model that defines this reality.
