Description
Technical Field
The invention belongs to the technical field of educational resource right confirmation, and particularly relates to a multi-source digital educational resource right confirmation method based on an intelligent contract.
Background
In recent years, with the rapid development of education informatization, the number of digital education resource copyright transactions and the transaction scale are rapidly expanded. By 1 quarter in 2018, the related transaction scale of the copyright of the domestic Internet education market reaches 682 million yuan RMB, the commensurately increases by 48.9%, and the transaction scale of the digital resource copyright in China in 2018 is predicted to break through 3000 million yuan. At present, the problems of complicated reading right and ownership confirmation, non-real-time property, frequent infringement and the like still exist in digital education resources. Copyright protection of digital educational resources is to provide protective measures for resource usage and management to prevent unauthorized use and ensure the integrity of digital content. The traditional education resource platform still has the following problems for protecting the rights of digital education resources: (1) when copyright infringement occurs, a person responsible for disclosing the copyright cannot be tracked and locked, and the behavior of infringing the copyright lacks real investigation; (2) the definition of the rights is unclear and the classification and protection of the rights with fine granularity are lacked. For example, copyright protection is limited to only protecting digital resource ownership, and protection of reading rights is ignored, the reading rights refer to rights for resources to be viewed and downloaded, and producers of digital education resources can bring knowledge back through selling of the reading rights, so that value is created for the producers, and knowledge innovation is promoted.
The multi-source digital education resources aim at digital resources under multiple platforms, resource information among different education resource platforms is not intercommunicated currently, high-quality education resources can only be shared in a single resource platform, in the resource transmission process of different platforms, a lot of time is consumed in the traditional authorization links such as application, registration and review, the problem of difficulty in real-time authorization exists, due to the lack of protection of resources, the legal rights of right owners cannot be powerfully guaranteed, and numerous resource owners are unwilling to share and exchange data without compensation, so that the integration and sharing of resources are seriously hindered. The digital education resource right confirmation is a copyright protection for resources, and the key problems are that the problems of right confirmation and right protection for the education resources are solved, a resource copyright protection and transaction mechanism is established, the right confirmation and protection for copyright resources in a classified mode are determined, free circulation of the education resources among different platforms and quick change of high-quality resources can be well achieved by using a block chain system, and meanwhile real-time right confirmation in the resource transmission process is guaranteed.
The intelligent contract is essentially code running on the blockchain, the intelligent contract coding realizes business logic and can automatically run on the blockchain, and once the contract is validated on the blockchain, the corresponding business logic automatically runs. Meanwhile, the cryptology characteristic of the block chain and the multi-party backup mechanism ensure that the intelligent contract can be tracked and cannot be tampered, and any transaction participant can not change the transaction logic any more, so that the fairness of the transaction is ensured. Specifically, compared with the traditional contract, the intelligent contract has the characteristics and advantages that the problem of credit is solved, the resources on the blockchain are real and transparent, the contract content cannot be changed after being determined, the execution is not dependent on any additional operation, and the privacy and the safety of the resources on the blockchain are ensured. The block chain has the characteristics of self, is very suitable for copyright confirmation, and copyright transaction can reduce the cost of a copyright confirmation link through an intelligent contract.
The traditional copyright transaction is generally carried out on line, and both parties realize resource right confirmation by signing a copyright transaction protocol, but the mode has the characteristics of no standard, low transparency and difficult right maintenance, and the existing traditional copyright protection mode can hardly meet the protection requirement of digital resources. Currently, there is a method for applying blockchain to copyright protection, which uses the technical feature of blockchain "decentralized" to embed 16-ary password into original digital education resource, and this password will be stored in the blockchain system of decentralized structure at the same time, and this method is used to achieve the security of resource authorization and copyright transaction, however, this method still has the following problems: (1) the exercise and tracing process of all rights of the digital resource cannot be normalized; (2) settlement and right confirmation in the copyright transaction process cannot be solved in real time; (3) the real-time right confirmation of the educational resources under multiple platforms cannot be realized.
