The "balance of interests principle" seeks to find a balance between "maintaining the development of the Internet industry" and "protecting the legitimate rights of copyright owners", so that the balance of interests of multiple parties can be achieved. The key lies in clarifying the obligation of network technology service providers to protect the copyright of others. This article clarifies this: before an infringement occurs, the network technology service provider cannot directly infringe the copyright of others, and must exercise reasonable care and the obligation to "build a copyright database". When an act of infringement occurs, the online technology service provider must comply with the "notice-and-delete" rule, fulfil its obligation to "forward notification" and provide an obvious channel for complaints. After an infringement has occurred, the OTS provider has an obligation to assist the "rights holder" in its investigation and to prevent repeated infringements by unusual Internet users.
