The problem of data right confirmation is a long-term bottleneck in data *** methods for confirming data rights lack credibility owing to poor supervision,and work only with specific data types because of their technical *** emergence of blockchain is followed by some new data-sharing models that may provide improved data ***,few of these models perform well enough in confirming data rights because the data access could not be fully under the control of the blockchain *** view of this,we propose a right-confirmable data-sharing model named RCDS that features symbol mapping coding(SMC)and *** SMC,each party encodes its digital identity into the byte sequence of the shared data by generating a unique symbolmapping table,whereby declaration of data rights can be content-independent for any type and any volume of *** blockchain,all data-sharing participants jointly supervise the delivery and the access to shared data,so that granting of data rights can be openly *** evaluation results show that RCDS is effective and practical in data-sharing applications that are conscientious about data right confirmation.
