基于情境感知的区块链中防伪溯源技术研究
首发时间:2020-03-12
摘要:随着区块链技术多样性发展,越来越多领域开始尝试使用区块链技术解决问题。区块链具有不可更改的特点,区块之间用时间戳链接,天然具有溯源的优势。与此同时,人们追求优质多样化产品与造假行为之间的矛盾依然存在,利用区块链技术优势的同时增加溯源系统防伪能力是本课题的研究目标。基于以上目标,本文结合区块链智能合约自动执行的特点,基于情境感知技术设计了自动防伪报警算法,针对抽象造假产品在市场流通的特点,对溯源产品增加防伪可信值,使得每个产品的防伪可信值可以基于溯源流程中对产品区块数据的操作而变化,溯源产品个体的真伪相关状态可以表示为向量 X=(x1,x2,x3,…,xn),其中 xi 为某个步骤会对真伪有影响的操作。当然最终的真伪可信值表示为Y=F(X),其中Y为最终作为真伪判断的目标值,可信值的变化会触动智能合约中的防伪操作,自动向用户告警同时触发监管部门后续操作。自动防伪报警算法增加了区块链溯源系统的防伪能力,减少了有关部门的监管成本,促进区块链在现实领域的应用。

Research on Anti-fake Traceable Technology in Blockchain based on Context-awareness
Abstract:With the development of blockchain technology, more and more companys begin to try to use blockchain technology to solve their problems. Blockchain is unalterable, and the blocks are ordered by timestamps so that it has the advantage of traceability naturally. At the same time, the contradiction between people\'s pursuit of high-quality and diversified products and counterfeiting behaviors still exists.Using the advantages of blockchain technology while increasing the anti-counterfeiting capability of the traceability system is the research goal of this subject. Based on the previous point, this article combines the characteristics of blockchain smart contract automatic execution, based on Situational Awareness technology, we designed an automatic anti-counterfeiting alarm algorithm and aimed at the characteristics of abstract counterfeit products circulating in the markets. Adding anti-counterfeit credible value to traceable products could make the anti-counterfeit and trusted value of each product change with the operation of product block data in the traceability process. The authenticity of the traceable product individual can be expressed as vector X=(x1,x2,x3,…,xn) , which xi is an operation whichhas an effect on authenticity in operation.The final authentic value is expressed as Y=F(X), and Y is thefinal target value of the judgment. Changes in trusted value will trigger anti-counterfeiting operations in smart contracts. Automatically alert users and trigger follow-up actions by regulatory authorities.The automatic anti-counterfeiting alarm algorithm increases the anti-counterfeiting capability of block chain tracing system, reduces the supervision cost of relevant departments, and promotes the application of block chain in the real world.
