摘要
随着大数据的不断发展,数据的收集和共享得到重视,产生了大量数据交换平台。然而大部分平台将重点放在数据安全与用户隐私的考量上,从而忽视了用户交换意愿方面的问题——实际应用中用户往往因为缺乏足够的动机而少有交换意愿。针对该问题,构建了一种基于区块链的数据交换激励框架,提出了一种基于历史贡献和当前贡献的数据交换激励机制,一方面从历史维度考量用户的过往表现,另一方面从当前维度考量用户的实时贡献。对所提出的方法进行了理论分析和实验评估,结果表明该激励机制能够有效起到长期激励用户进行积极正向数据交换的作用。
With the sustained development of big data,data collection and sharing are highly valued,resulting in a large number of data exchange platforms.However,most platforms focus on data security and user privacy,but neglecting the issue of users′willingness for exchange.In practical applications,users often have little willingness to exchange due to a lack of sufficient motivation.In response to this issue,this article constructed a blockchain based data exchange incentive framework and proposed a data exchange incentive mechanism based on historical contribution and current contribution.On the one hand,it considers users′past performance from the historical dimension.On the other hand,it considers users′real-time contributions from the current dimension.The article conducted theoretical analysis and experimental evaluation for the proposed method,and the results show that the incentive mechanism can effectively motivate users to engage in positive data exchange in the long term.
