Description
Technical Field
The invention belongs to the technical field of block chain technology application, and particularly relates to a digital content distributed transaction method, a system, a storage medium and computer equipment.
Background
The internet technology is developed at a high speed, the network increasingly becomes a high-incidence and easy-to-develop field of infringement piracy, the copyright industry taking innovation as a core faces a serious challenge, and the video work case grows rapidly. The size of picture copyrights has increased from 161 million RMB in 2015 to 240 million in 2019. The block chain has the inherent advantages of openness, transparency, traceability and non-falsification, and plays an important role in the protection work of intellectual property rights. Even if blockchain + title protection applications exist, copyright protection still faces the following problems:
the piracy phenomenon is rampant to infringe the interests of the copyright holders, and the copyright holders are infringed by the impossibility of clearing the royalties and the low income. The reasons for the difficult settlement of royalties and the low royalties are as follows: one is that the benefit distribution system is imperfect. In the digital publishing industry, digital platform operators and terminal equipment manufacturers master digital authors' bargaining digital work distribution channels, and have a dominant position in a copyright profit distribution system, and content providers or originality are weak, so that equal profits conforming to the real value of the works cannot be obtained in profit distribution. The second is that the revenue calculation mode is opaque. Taking the music industry as an example, distributors have strong channel control force, the use of music works for record making, music live performance and movie and television series is transparent, and copyright income is determined, but digital copyright channels tend to be diversified, and music originators authorize copyright to pay to the music, and the income comes from the calculation of song download amount and click rate. However, the data is opaque, falsified and difficult to monitor, and the original author and the content provider cannot control, so that royalty settlement is opaque and income is delayed, and the benefit of the original author is difficult to guarantee. Third, low awareness of content payment results in low overall revenue. The social recognition of the pursuit of free or cheap use utility results in the incomplete formation of the institutional environment of user's paying habit and respecting copyright and paying to obtain resources. In addition, the immaturity of the continuous profit model leads to undesirable royalty income for content providers and originators, and influences the originators to create enthusiasm.
Through the above analysis, the problems and defects of the prior art are as follows: in the prior art, copyright settlement is difficult, a benefit distribution system is imperfect, a profit calculation mode is opaque, and the content payment consciousness is low, so that the overall income is low.
The difficulty in solving the above problems and defects is: the key point of applying the digital product to transaction lies in constructing a third-party transaction platform which can be trusted by both buyers and sellers, and simultaneously, the operation convenience is improved as much as possible, and the transfer of picture copyright or the endowment of use right can be completed under any condition. The difficulty in solving the above problems is how to design a transaction method and a transaction system so that the trust of the buyer and the seller can be obtained.
The significance of solving the problems and the defects is as follows: in the current society, the scale of picture copyright rises year by year, and networks increasingly become the highly-prone field of infringement piracy. The profit calculation mode of the copyright maintenance platform is not transparent, and the prior art has the problems of difficult copyright settlement and the like. The problem is solved, the trust of the user on the platform can be enhanced, and more people are guided to join the queue for protecting intellectual property rights.

A seller transaction sub-module: after the transaction is started, the seller encrypts the digital commodity information and sends the encrypted digital commodity information to the buyer. And after the partial points of the buyer are frozen by the judge sub-module, the seller sends the encryption key to the buyer through the judge sub-module. However, if the digital goods sent by the seller are false, the frozen points will not be entered into the seller's account, but instead are returned to the buyer's account by the judge module.
The buyer transaction submodule: after the buyer receives the digital commodity encryption data of the seller, the judge freezes partial points of the buyer. After the buyer receives the encrypted key of the digital commodity of the seller through the judge, the encrypted data of the digital commodity is decrypted and whether the data of the digital commodity is correct or not is verified. When the buyer verifies that the data is wrong, the buyer provides relevant data to the judge so that the judge can verify the authenticity of the data. And when the judge verifies that the data is wrong, the credit of the buyer is unfrozen and the transaction is ended, otherwise, the transaction is continued, and after the transaction is finished, the judge sends the frozen credit to the seller.
A judge module: the intelligent contract in the product serves as a judge which plays a role in making the transaction safe. When the legal officer receives the encryption key sent by the seller, the encryption key is stored and then sent to the buyer. And after receiving the verification result and the partial data sent by the buyer, the judge verifies whether the data of the transaction is wrong through the encryption key and the partial data which are stored before. And if the data has errors, unfreezing the points of the buyer, ending the transaction and returning the frozen points to the buyer, otherwise, continuing the transaction, and after the transaction is finished, sending the frozen points to the seller by the judge.
Further, the safety protection module is composed of a digital commodity encryption sub-module, a user identity privacy protection sub-module and a fund transfer sub-module, and the details are as follows:
