Digital product secure transaction system and method based on blockchain technology

Abstract

The invention provides a digital product secure transaction method based on a block chain technology and a system for realizing the method, solves the problem of right and interest guarantee in a digital commodity transaction process, and confirms ownership of a commodity through a digital watermarking technology and one-time asymmetric encryption from the perspective of a commodity provider; from the perspective of a commodity demander, malicious attacks can be effectively prevented in the transmission process of commodities through symmetric encryption, authenticity and effectiveness of the commodities are guaranteed, and it is guaranteed that the commodities can only be effectively accessed by a commodity demander through secondary asymmetric encryption; once transaction is completed, whole transaction information is uploaded to a block chain and cannot be tampered manually, transaction records can be checked, and the method can be used for responsibility investigation after events. According to the invention, the data security is guaranteed from three aspects of right confirmation, right use and right protection by utilizing a block chain technology and combining digital watermarks, so that the security in the digital commodity transaction process can be improved, the ownership of digital commodities is guaranteed, and legal disputes possibly generated by buyers and sellers after transaction are effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of computer security, relates to block chain technology, in particular to a digital product security transaction method based on block chain technology and a system for realizing the method. Background technique [0002] With the increasing development of network technology, the network transaction volume of digital products has been greatly increased year by year. During the online transaction and transmission of digital products, digital information is easily tampered with, copied and distributed; therefore, how to protect it is an important issue. The data transaction method in the prior art only uses the traditional digital watermarking technology to contribute from the perspective of data rights protection, and lacks all-round and multi-angle control of digital products and their transaction process. After analysis, we found that the existing implementation method only simply completes the delivery of ...
