"A 43-year-old man is the second known person arrested in Japan for using Perfect Dark to share copyrighted material in its encrypted P2P network.According to the [Kyoto-based] High-Tech Crime Task Force, the Okayama police, and the Saga police, the Osaka-based suspect uploaded about a thousand files, including anime. The suspect admitted that he thought he would not get caught because he was using Perfect Dark.
Perfect Dark is the third generation of japanese anonymous P2P network clients, developed with the intent to fix the security flaws found in its predecessors Winny and Share, in spite of also adopting a "Secure through Obscurity" closed-source model. In 2004, Winny's developer, Isamu Kaneo, was charged 1.5 million yen for assisting in copyright infringement, but he was acquited last October. Since 2008, at least 15 people were arrested in Japan suspect of uploading copyrighted material to those "secure" networks."
