User's Liability on the Copy of Online-Contents

The peculiarities of online-contents give rise to a serious trouble on copy of online-contents between the authors and the user. In spite of the possibility of a mass copy on internet, the copyright belongs to same family as the ownership. And Copyright Act enforce the regulations of user' liability on piracy. I examined two issues in detail. First, I asked the copyright belong to same family as the ownership. And I found that works is distinguishable from things in essence as well as in outward form. So the regulation of the duration and extinctive prescription apply to the copyright. Second, I asked that it is possible to get rid of the trouble on the copy of online-contents between the authors and the user. And I found that the authors putting the contents out to internet owe the duty of care and diligence to the unlawful copy of online-contents. So if the authors'sign is not on the online-contents, he can not lay claim to the copyright to the bona fide user of copy. By the time, the copyright is under discussion on the protection or the due to the public welfare. But it is necessary to be a lively discussion on works in essence and the bona fide user(customer). In adversary system, I hope to find the reasonable standpoint of the user' liability on piracy.
