Online copyright protection is covered under copyright laws, and those who are victims of copyright theft may pursue legal means to stop copyright violations and in some cases recover monetary damages. Many web users who post copyrighted material on the Internet use programs designed to track their content on the Internet These programs often function like search engines, scanning the web for duplications. Other users may simply use standard search engines to make sure their material hasn't been stolen or unlawfully republished. Often, copyrights may be violated accidentally by web users who are unaware of specific copyright laws. A person may, for example, reprint an article on their personal website without properly attributing it. In these cases, often a simple email explaining that a copyright has been violated is all that is required to remedy the situation. In other cases, a tougher approach may be needed. Filing an official copyright infringement notice may be necessary in order to resolve certain copyright violations.
