| The updating and improvement of copyright system are based on the advances in technology, the development of which is driving forward the relevant copyright legislation. The coming era of cloud computing is neither the first challenge of copyright protection nor the last. With the maturation and promotion of its technologies, it has gradually become the main way for information processing of individuals, companies or institutions. The new operating mode based on meta-computing greatly affected the formation of the copyright law system. Cloud computing contains three service modes-Infrastructure as a Service, i.e. IaaS, Platform as a Service, i.e. PaaS and Software as Service, i.e. SaaS.With the development of information technology, as a new type of applications software, SaaS is different from the traditional physical sales mode in the aspect that it is transformed into an software operation mode with leased properties, setting the required software in its cloud servers and providing temporary use for the users with compensation. The same software will be able to simultaneously leased to multiple tenants. This paradigm shift puts forward higher requirements, for copyright protection of software. Under the SaaS mode, when the cloud service provider, as the provider of specific software works, provide works to relevant users without authorization, by which exclusive right of the copyright owners can such behaviour be controlled? These are the issues need to be explored.We need to further explore how to solve the applicable problem of the exclusive right of the current copyright system in governing the provision of software and service under the SaaS model. Based on the analysis and considering the fact that the using actions of SaaS software are consistent with the core elements of the rental right, the writer thought an explanation with moderate expansion can not only meet their own content, but also agree with the dominant effect of the rental right. Besides, the author also thought providing software services under the SaaS mode bears the applicable feasibility of rental right, but we need to expand the explanation of the rental right in the traditional copyright.Cloud computing service providers’strong protection of its service system may upset the balance of intellectual property rights as private rights and public interests. If the interest fails to keep balance, resistance may occur among public, which is also detrimental to the development of cloud computing technology and ultimately damages the benefit of more people. |
